Abstract. Profitability is an underestimated concept in precision agriculture. In this research, a new module is
developed within a pre-existing farm management system to assess the profitability of precision agriculture
applications in extended crops. The module is regulated on a 5-meter spatial resolution, thus allowing scaling
up of original and processed data on a zone-, field-, cultivar-, and farm-scale. A bottom-up approach, taking
advantage of the full functionality of the farm management system, together with a flexible architecture and
an easy-to-use interface, renders the new module an innovative commercial application.

1. Introduction
1.1. The problem
The financial success of a business can be evaluated by its profit and profitability. Profit refers
to the absolute measure of earnings minus the expenses involved in achieving a particular outcome.
In a market-driven economic system, it is imperative for entrepreneurs to prioritize profit realization,
as failure to do so compromises the sustainability and longevity of their enterprise [1]. Apart from
maximizing profits, though, the goal of any agricultural enterprise is also to minimize costs.
Profitability represents a relative measure of a company's effectiveness, allowing for a
comparison between the achieved outcome and the associated costs [2]. To ensure the profitability of
an agricultural enterprise, efficient management is essential, typified by tasks such as soil tillage, crop
planting, irrigation, weed management, pest, and disease control, and harvesting.
Further, effective farm management requires a combination of knowledge, skills, and
experience, and often involves the use of technology and data-driven decision-making. The key lies
in effectively utilizing production resources and adopting advanced techniques to produce crops [3].
It is crucial for businesses to prioritize maximizing their profits within the limitations of available
resources, including financial and credit resources, material support for production, and the
necessary skills to carry out the tasks of the workforce [4].
Precision Agriculture (PA) is one of several methodologies which can improve farm
management by providing timely, thorough, site-specific crop information within a decision-making
framework. Data can be retrieved from a variety of sources, such as soil sampling, sensors, weather
stations, satellite or drone images, and yield monitors.
As a tool facilitating farmers to more efficiently manage their land, precision agriculture
significantly and variously impacts farm management. According to global trends, the application of
precision agriculture worldwide is estimated to increase in the next four years, with the market value
doubling from 17.41 billion U.S.in 2022 to 34.1billion U.S.in 2026 [5].
The main goal of precision agriculture research is to define a decision support system (DSS) for
whole farm management with the aim of optimizing returns on inputs while preserving resources

[68]. However, farming is a complex endeavor involving many factors and inputs, such as land cost,
labor, expensive machines and various tools, fertilizers, pesticides, and irrigation. In most cases,
farming activities are not properly logged, at least not in a systematic and analytic way, while most
data are fragmented, dispersed, and difficult to use [9].
According to a recent review based on 23-year meta-analysis [10],
profitability, consultancy, and computer use had only a moderate effect on the adoption of precision
agriculture. However, these findings should be viewed cautiously due to issues of sample size and
heterogeneity embedded in some of the reference studies, while at the same time, other factors had a
negligible effect on adoption. Precision agriculture must be discriminated from “smart agriculture”,
regarding the concept of site-specificity. Smart agriculture is associated with various types of sensors
used (soil, moisture, climatic, etc.) to derive crop information (and potentially return a decision),
regardless satisfaction of within-field spatial variability, as it happens with precision agriculture
practices.
1.2. State of the art
Lately, several farm management platforms and technologies have become available to support
precision and smart agriculture applications; below are some indicative platforms in English
available in the market:
Climate FieldView: An integrated digital platform that collects and analyzes field data, helping
farmers make more informed decisions regarding crop management, planting, and harvesting.
The available tools allow farmers to manually delineate management zones
(https://www.fieldview.com.au/).
Granular’s Farm Management Software (FMS), credited as the first cloud-based, mobile-centric
program of its kind, offers an intuitive breakdown of everything a farmer needs to consider,
from financial to soil management to operations. The platform is mostly oriented to sensors and
smart agriculture (https://www.corteva.com/resources/media-center/granular-provides-new-
digital-nitrogen-management-options-to-farmers.html).
Farmers Edge: A comprehensive smart agriculture platform that includes field-centric data
collection, satellite imagery, variable rate technology, and weather analytics to optimize farm
operations (https://farmersedge.ca/).
Agworld: A collaborative farm management platform that allows farmers, agronomists, and
other stakeholders to work together on planning, budgeting, and reporting of farm activities. It
incorporates add-in applications for specific works (e.g. Satamap for satellite image display)
(https://www.agworld.com/us/).
Taranis: This platform uses artificial intelligence (AI)-driven image analysis, combining high-
resolution aerial imagery and field-level weather data to detect and predict pest and disease
issues, enabling farmers to make proactive decisions (https://www.taranis.com/).
Trimble: A platform offering a range of precision agriculture solutions, mostly oriented to
equipment and automation, including guidance and steering systems, flow and application
control, yield monitoring, and water management tools
(https://agriculture.trimble.com/en/products/software/trimble-agriculture-software).
Sentera: A platform that integrates drone and satellite imagery with sensor data, enabling
farmers to monitor plant health, track growth, and identify potential issues
(https://sentera.com/).
John Deere Operations Center: A web-based platform that helps farmers track equipment,
manage field data, and analyze agronomic information to optimize their operations
(https://operationscenter.deere.com/).
Topcon Agriculture: A suite of visualization and decision-making tools including auto-steering
systems, variable rate control, yield monitoring, and farm management software
(https://tap.topconagriculture.com/).
Raven Industries: Providing automations like guidance and steering systems, application
controls, and field computers to help farmers optimize their operations (https://ravenind.com/).

Most of the above solutions -although quite technologically advanced- respond partially or even
inadequately to the need for an integrated site-specific management. Moreover, economic records
stored in the database (if they exist) are not always effectively linked to relevant precision farming
data, or (even if they are), the platform leaves the user alone to carry out the analysis or make out the
decisions. Therefore, in all cases there is a gap between available data, decision making on site-
specific applications, and their economic evaluation.
To bridge this gap between farm management and precision agriculture applications, two Greek
enterprises, Agrostis and Ecodevelopment, cooperated in 2022 to incorporate a site-specific
fertilization service (namely PreFer) into a pre-existing Farm Management Information System
(FMIS) (namely ifarma) [9].
ifarma was introduced to the Greek market in 2014 by Agrostis, as a cloud-based farm
management information system (FMIS). The data model of ifarma integrates all information relevant
to a farm, such as fields and land parcels, crops, farming activities on fields and inputs and resources
used to plan and execute these activities. This data model organizes the information in a hierarchical
manner, where the farm is at the top. Today, ifarma is a well-known trademark recognized as the
best farm management software for agricultural holdings in Greece [11].
PreFer service developed by Ecodevelopment, produces prescription maps, which together with
a variety of spatial layers (including soil properties, agronomic information, crop indices, statistical
and predictive climatic parameters, and yield records) become available to the farmers on 5-meter
spatial resolution on a regular basis. The prescription maps are created within a GIS, where big data
are analyzed using machine learning methodologies [12].
1.3. Objectives
Going a step further, the objective of this research was to offer a complete and easy-to-use
commercial solution for profitability assessment of precision agriculture applications in extended
crops on an annual basis.
Accordingly, a new module was developed within the ifarma farm management platform using
PreFer functionalities, especially its mapping environment and algorithms, thus facilitating
interoperability, swiftness, and ease. In this respect, the next Section will present the materials and
methods employed, Section 3 will demonstrate the results along with discussion and Section 4 will
provide the main conclusions of this work.
2. Materials and Methods
2.1. System architecture
The new profitability module, namely, ProFit, is an independent module of the ifarma FMIS, in
terms of interface and algorithms, although it cooperates with the PreFer module of ifarma, for
exchanging map data. More specifically, ProFit takes spatial data from the PreFer database as input
into its algorithms and returns output maps for display in the map viewer of PreFer. In this way, the
original PreFer (say v.1) is upgraded into a new version (say v.2) after integrating with ProFit (Figure
1).

Figure 1. The architecture of ProFit, based on its conjunction with PreFer module of ifarma.
Going a step further, the objective of this research was to offer a complete and easy-to-use
commercial solution for profitability assessment of precision agriculture applications in extended
crops on an annual basis.
ProFit alone comprises two components (Figure 2). A site-specific cost component, which is fed
by the database of PreFer, where the precision agriculture applications are stored and displayed. A
shared cost component for other (non-precision agriculture) practices, where the required records are
manually entered as lump sum amounts. The site-specific cost component takes input from two kinds
of spatial data: a) the fertilizer application maps and b) the yield maps. The former is used to calculate
fertilization cost at every surface unit (of 25 m2) after the multiplication of the fertilizer’s rates with
its corresponding unit cost; the latter, meanwhile, are used to calculate earnings at every surface unit
after the multiplication of the yield with the price of the corresponding cultivar in the market.
The shared cost component holds the lump sum amounts per expenditure category. The
distribution of these lump sum costs is then based on an empirical classification of the fields of the
farm according to a degree of difficulty (or weighting factor) on a categorical scale of 1-5, with ‘1’
corresponding to the easiest field and ‘5’ to the most difficult for each of the agriculture practices
applied (e.g., soil tillage, irrigation, weed management, etc.).
The output data will be in two forms: a) descriptive statistics of cost, earnings, and profit per
field; and b) profitability maps (cost, earnings, and profit maps) at a 25-m2 surface unit. The
calculations will be done automatically according to embedded formulas.

module).

2.2. Data requirements
The data entry of the shared cost records in ProFit is carried out manually through a new form
which is divided into two sections, each corresponding to a number of agricultural practices. The site-
specific data will be read from the maps stored in the PreFer database.
The shared cost data are related to total annual amounts for the entire cultivation and can be
divided into the following categories (using a common ordering regardless change of category):
Section A (related to categorized total annual costs):
1. Land rent
2. Seeds
3. Irrigation
4. Fertilizers
5. Weed killers
6. Pesticides/Insecticides
7. Harvest
8. Machinery
a) Depreciation
b) Maintenance
c) Spare parts
Section B (related to total annual costs per field):
9. Land rent (absolute amounts)
10. Degree of difficulty per field for shared cost (weighting factor: 1-5)
d) Seeds
e) Irrigation
f) Fertilizers
g) Weed killers
h) Pesticides/Insecticides
i) Harvest
j) Machinery
2.3. Algorithms developed
A set of interrelated functions have been setup for ProFit, which carry out arithmetic, categorical,
and logical operations, and transfers of tabular data. The overall arrangement is integrated and
executed in a prototype Excel spreadsheet, where all internal functions and options and the external
data feed are arranged. The monetary rate unit is set to euros per hectare (€/ha), the fertilizer amounts
in kilograms per hectare (kg/ha), and the yield in tonnes per hectare (t/ha) (Figure 3).

The basic formula for cost, earnings, and profit calculations applied per field, is shown simplified
below:
Cost =
Field Rental Cost +
Field Shared Cost for Agricultural Practice [1] +
Field Shared Cost for Agricultural Practice [2] +
Field Shared Cost for Agricultural Practice [3] +
Field Shared Cost for Agricultural Practice [8c] +
Quantity of Fertilizer-1 [Input from the Fertilization Maps of PreFer database] x Price of Fertilizer-1
(manual input in relevant table) +
… (as many times as the number of fertilizers, n)
Quantity of Fertilizer-n [Input from the Fertilization Maps of PreFer database] x Price of Fertilizer-1
(manual input in relevant table)
Earnings = Yield (t/ha) [Input From the Yield Map] x Cultivar Price (monetary unit/kg) [Input from
the Crop List]
Profit = Earnings Cost
For splitting the shared cost lump sums of the different agricultural work categories into cost
items per field, a stepwise procedure is followed (Figure 4):
1. First, the rate of difficulty of each field is multiplied by the field’s extent and then divided
by the number of fields under consideration, to give a weighted rate of difficulty.
2. Then, the weighted rate of difficulty of each field is divided by the total weighted rate of
difficulty to give the cost share for the field (for each of the shared cost categories).
3. Finally, the cost share of every field is multiplied by the total cost of the category and
divided by the number of fields to give the absolute cost per field (for that cost category).
Therefore, for every category, the algorithm retrieves the lump sum amount for the entire
cultivation from a manually filled table and the field extents from the farm’s geodatabase (i.e. from
PreFer). Thus, the only inputs required by the algorithm are the rates of difficulty per field and for
each work category. An internal control function will check if the earlier entered lump sum for the
working cost category is equal to the one calculated by the algorithm.
Figure 4. An example of the cost lump sum splitting algorithm (prototype) (same dataset as Figure 3).
3. Results and Discussion
3.1. System functionality
The new module ProFit comprises a spatial and a non-spatial component. The spatial component
is developed in the pre-existing module PreFer within the ifarma FMIS. As a result, the output maps
of ProFit follow the same standards as that of the PreFer module, i.e., a spatial resolution of 5 meters
(surface unit of 25 m2) and a classification of the original values into 7 categories.
The non-spatial components include output tables which at the same time contain the entire
input information. Thus, the user gets the whole economic picture of the cultivation in a single tabular
arrangement.

3.2. System interface
The ProFit module is available as an option in the main menu of the ifarma interface, specifically
in the ‘Management of works, inputs, and yields’ group (currently only in Greek). By clicking the
ProFit button (set below the ‘PreFer’ option), the input form for entering values for the required
economic items is launched in a single web page (Figure 5). For convenience, the output fields are
displayed in a different form after the execution of the calculations and can be exported to
spreadsheets.
Apart from the tabular output data (e.g., statistics per field and the entire cultivation), which are
displayed on a different web page of the ifarma environment, the output maps are displayed within
the PreFer map viewer. The options for displaying the cost, earnings, and profit maps for every
cultivation are available inside the ‘Performance’ group of options in the PreFer map viewer menu
(which also includes the yield maps).
3.3. Experiences
Most of the existing platforms in the market are top-down, originating from the need of an
already established market player to promote its products, services, or goods through the concepts
of precision agriculture. In most cases, these platforms provide financial management as a parallel
service to another main service, e.g., fleet management, crop calendar, etc.
Conversely, ProFit on ifarma follows a bottom-up approach, starting from the applications and
considering all the farming details to conduct a thorough economic analysis, while enabling spatially
distributed outputs in terms of maps.
The development team was assisted significantly by several farmers who implemented precision
agriculture over the course of years, through their ideas and experience and by using and testing the
module with authentic farming data from the 2022 cultivation year in Greece.
Using real data combined with some notional options, for example, in the selection of the
difficulty factors per field, to test the module under extreme data ranges it was noticed that yield
maps might be quite different from profitability maps (especially between fields) (Figure 6).

5. Conclusions
In this research, an innovative module for assessing the profitability of precision agriculture
applications was developed, namely ProFit. In terms of architecture, ProFit is embedded within a
cloud-based farm management information system, namely “ifarma”, while taking advantage of pre-
existing functionalities, such as a precision agriculture database provided by other ifarma modules,
like PreFer.
ProFit offers an easy-to-use interface, which encourages farmers to enter economic records
quickly and reliably, while using an empirical method to share apportionable expenditures between
fields (when and where site-specific maps are not available). At the same time, it uses the map view
environment of PreFer to display the profitability maps.
Future work will focus on widening the range of precision agriculture practices (I.e., beyond
fertilization) within ProFit, such as soil tillage, seeding, irrigation, weed management, and crop
protection.

Article
In this work, an innovative process chain is set up for the regular provision of fertilization consultation services to farmers for a variety of crops, within a precision agriculture framework. The central hub of this mechanism is a geographic information system (GIS), while a 5 × 5 m point grid is the information carrier. Potential data sources include soil samples, satellite imagery, meteorological parameters, yield maps, and agronomic information. Whenever big data are available per crop, decision-making is supported by machine learning systems (MLSs). All the map data are uploaded to a farm management information system (FMIS) for visualization and storage. The recipe maps are transmitted wirelessly to variable rate technologies (VRTs) for applications in the field. To a large degree, the process chain has been automated with programming at many levels. Currently, four different service modules based on the new process chain are available in the market.

The purpose of this paper is to conduct an empirical investigation of the theoretical and literature-based constructs related to the adoption of precision agriculture (PA) practices by young farmers. For this research, primary and secondary data are used. The sample includes 220 young farmers. Among the results of this research, farmers are aware of the positive effects of technology systems in agriculture. Also, young farmers seem to be familiar with precision agriculture and have already adopted some of its methods, but the high cost of investment prevents farmers from adopting such technology. Innovative technologies and production methods can help young farmers to be competitive in the worldwide market.

Today, bridging precision agriculture (PA) with farm management is a high priority. To answer to this challenge, a precision fertilization service for extended crops was embedded as a new module in the platform of a pre-existing cloud-based farm management information system (FMIS), namely ‘ifarma’. The new module (namely, ‘PreFer’) uses interoperable geospatial formats, to guarantee free and rapid data exchange between a server-based geographic information system (GIS) and the ifarma platform. The GIS is used to store and process the complete farmers’ geodatabases, which are fed with data from multiple sources (e.g., soil surveys, satellite data, yield monitors, etc.). It is also used to feed the machine learning algorithms of ‘PreFer’ with the required data to produce the fertilization prescriptions in the form of digital maps. All the necessary maps are transferred automatically to the platform upon their production, where they can be viewed by the farmers. The platform is used also by farmers to insert pre-known or last-minute agronomic information required to the analysis. The overall developmental experience showed that such a customized application (such as ‘ifarma/PreFer’) is the most effective solution today, compared to other alternatives, towards fully operational precision agriculture services.

The scope of this research was to provide rice growers with optimal N-rate recommendations through precision agriculture applications. To achieve this goal, a prediction rice yield model was constructed, based on soil data, remote sensing data (optical and radar), climatic data, and farming practices. The dataset was collected from a rice crop surface of 89.2 ha cultivated continuously for a 5-year period and was analyzed with machine learning (ML) systems. A variational autoencoder (VAE) for reconstructing the input data of the prediction model was applied, resulting in MAE of 0.6 tn/ha, with an average yield for the study fields and period measured at 9.6 tn/ha. VAE learns the original input data representation and transforms them in a latent feature space, so that the anomalies and the discrepancies of the data are reduced. The reconstructed data by VAE provided a more sophisticated and detailed ML model, improving our knowledge about the various correlations between soil, N management parameters, and yield. Both optical and radar imagery and the climatic data were found to be of high importance for the model, as indicated by the application of XAI (explainable artificial intelligence) techniques. The new model was applied in the 2022 rice cultivation in the study fields, resulting in an average yield increase of 4.32% compared to the 5 previous years of experimentation.

In the article we investigate the problem of determining the main factors of increasing the profitability of agricultural enterprises in order to effectively use the resource potential of agricultural producers. In this study, we used a set of modern scientific methods, among which we highlight such methods as factor analysis, structural analysis, graphical and tabular methods, grouping methods, regression statistical analysis, etc. In particular, grouping methods are used in the study for the distribution of the researched enterprise’s totality according to the special features of their functioning. Also in the process of our study regression, a statistical analysis method was used to build a regression model to assess the relationship of profit and revenue from agricultural enterprises with such factors as a capital ratio, the average annual amount of enterprise assets, the labour costs, and the number of material costs per unit of land area. Besides, in order to study the level of profitability of agricultural enterprises in terms of their organizational and legal forms of management, the scope of financial and economic activities as well as the unit of the occupied area, livestock and taking into account the products produced, we used the structural analysis method. According to the results of the study, we found that the profitability of agricultural enterprises in the Lviv region of Ukraine depends on the characteristics of their versatility. Thus, according to the results of the study we proved, that the constructed multifactorial correlation and regression models allow us to make the conclusion about availability of the significant impact on the profitability of the security of the agricultural enterprises in Lviv region of Ukraine and the level of their intensification of the production activities. Based on the study, it can be argued that the profit of agricultural enterprises is a key indicator for the implementation of the process of agricultural production, and is one of the main criteria for the effectiveness of the agricultural sector. It is determined that the activity of agricultural enterprises is significantly influenced by external factors that are not directly related to the production activities of enterprises.

Using a literature pool spanning 23 years, this meta-analysis quantifies the effect of factors underlying the adoption of precision agriculture. Unlike statistical significance, which demonstrates how likely adoption is due to chance, effect size indicates the importance of a factor to adoption. This meta-analysis finds that perceived profitability, consultants and use of a computer factors have a moderate effect. However, the findings should not be regarded as definitive because of issues of sample size and heterogeneity embedded in a number of the reference studies. This latter point is re-enforced by observation of other factors that had a negligible effect on adoption. Whether future studies will provide meaningful policy implications depend on a careful understanding and selection of factors, models, and statistical treatment in relation to decision-making paths and their context.

Precision Agriculture is advancing but not as fast as predicted 5years ago. The development of proper decision-support systems for implementing precision decisions remains a major stumbling block to adoption. Other critical research issues are discussed, namely, insufficient recognition of temporal variation, lack of whole-farm focus, crop quality assessment methods, product tracking and environmental auditing. A generic research programme for precision agriculture is presented. A typology of agriculture countries is introduced and the potential of each type for precision agriculture discussed.

As innovative information and communication technology (ICT) tools were gradually introduced over the past decades into the agricultural sector, the use of farm management information systems (FMIS) was widely expanded and nowadays are regarded as important tools for managing the agricultural business. Nevertheless, the necessary workload for collecting, aggregating and importing data related to farming activities into a FMIS, is a task which is often time-consuming and farmers are reluctant to perform. The current paper describes the implementation of three automation levels, which enhance a FMIS by providing solutions related to the collection of fragmented-missing data and time-consuming data entry. The three levels involve: (i) the development of a modular FMIS based on future internet technologies, (ii) the use of standard values for assessing the cost of performed agricultural tasks and (iii) automating the process of importing task-related data into a FMIS using tractor's CAN-Bus ISO 11783 and SAE J1939 communication information. To assess the financial analysis of the developed FMIS, related data were collected, recorded and analysed for an entire growing season, from two distinct crops, i.e. winter wheat and maize. Furthermore, to assess the automated task formulation in the FMIS, machine data were acquired while ploughing with a mouldboard plough. The application proved capable of performing a profitability analysis based on the recorded cost transactions but also based on the information given by the user related to the performed tasks. With the automatically created task, the FMIS gave the possibility to the user to present and process the necessary information with minimum effort.
