Full-text available
The article presents predicted changes in soil water content in the Bystra river catchment (eastern Poland) for various scenarios of climate change and adaptation practices obtained on the basis of a SWAT model simulation for three regional climate models driven by the global climate model EC-EARTH for the years 2041–2050 and the RCP 4.5 and 8.5 RC...
Article
To date, assessing the adaptive measures to climate change effects on cropping systems have generally been based on data from field trials and crop models. This strategy can only explore a restricted number of options with a limited spatial extent. Therefore, we designed a questionnaire that incorporated both qualitative and quantitative aspects of...

The aim of the study is a comparative assessment of the deep fertilizer placement method with surface broadcast application of fertilizers as rega...
Article
Sustainability assessment is a complex field and its uptake amongst agricultural producers limited. Furthermore, the scope of current sustainability assessment tools does not extend to systems in which food production is integrated with production of non-food biomass (e.g. agroforestry). Participatory approaches to tool development offer a means to...

In this study environmental efficiency of main root crop (sugar beets and potatoes) cultivation in Poland is evaluated. Survey data from 62 sugar beet and 74 potato farms in the years 2016 and 2017 were used for analysis. To assess efficiency, the slack based Data Envelopment Analysis model (SBM-DEA) was used, where greenhouse gas emissions were as...

Evidence shows that soil moisture (SM) anomalies (deficits or excesses) are the key factor affecting crop yield in rain-fed agriculture. Over last decades, Poland has faced several major droughts and at least one major soil moisture excess event leading to severe crop losses. This study aims to simulate the multi-annual variability of SM anomalies...

The results of the multifractal analysis performed for meteorological time series coming from four stations in Poland and Bulgaria located in varying climatic zones are presented. To assess climatic shift response (in 2001/2002), the analysis was conducted separately for two subsets. To analyze long-distance power-law correlations within the studie...

Europe accounts for around 20% of the global cereal production and is a net exporter of ca. 15% of that production. Increasing global demand for cereals justifies questions as to where and by how much Europe’s production can be increased to meet future global market demands, and how much additional nitrogen (N) crops would require. The latter is im...

Full-text available
Agro-meteorological quantities are often in the form of time series, and knowledge about their temporal scaling properties is fundamental for transferring locally measured fluctuations to larger scales and vice versa. However, the scaling analysis of these quantities is complicated due to the presence of localized trends and nonstationarities. The...

ABSTRACT. It is commonly accepted that an important role of phytochrome lies in signaling the proximity of competing plants. However, not all photoresponses conveyed by the phytochrome can be explained by the competition only. Because a better description of the natural variability of solar spectral irradiance is necessary to recognize the other ro...

Unsustainable production of agricultural biomass for electricity and heat can increase greenhouse gas emission and nitrates leaching. The DNDC (DeNitrification and DeComposition) model was used to estimate carbon sequestration and field losses of nitrogen, especially N 2 O emission in willow production. The model is capable of predicting willow yie...

To date, projections of European crop yields under climate change have been based almost entirely on the outputs of crop-growth models. While this strategy can provide good estimates of the effects of climatic factors, soil conditions and management on crop yield, these models usually do not capture all of the important aspects related to crop mana...

The studies on anthropogenic climate change performed in the last decade over Europe show consistent projections of increases in temperature and different patterns of precipitation with widespread increases in northern Europe and decreases over parts of southern and eastern Europe. In many countries and in recent years there is a tendency towards c...

Greenhouse gas emissions (GHG) were simulated from commonly used crop rotations in eastern Poland for conventional and conservation tillage systems. We used denitrification-decomposition (DNDC) model baseline climate conditions and two future climate scenarios (2030 and 2050). Analyzed cropping systems included corn, rapeseed, and spring and winter...

Since a positive trend of mean air temperature was observed over the last 40 years, the climatic “normals” i.e. averaged past observations ought not be used as a sole base for the agroclimatic analyses. The description of the recent climate needs also some prognostic measures. Because of the uncertainty of the causes and further evolution of climat...
Conference Paper
In the paper, infinite-dimensional, continuous-time control systems described by nonlinear and semilinear abstract differential equations are considered. Using methods of functional analysis sufficient conditions for constrained exact local controllability are formulated and proved. It is generally assumed that the values of controls are in a conve...

The predicted rapid increase of agricultural land areas with energy crops in the EU can cause transformation of significant amount of usual agricultural land and, as a result, lead to serious environmental implications. One of the consequences of high biomass production by energy crops is a concomitant usage of large amounts of water. Short rotatio...

The main source of risk for agricultural production is year-to-year variability in meteorological conditions. Moreover, many authors propose that variability in yields in recent decades become greater, meaning an increase in risk. This variability is usually calculated on the basis of residuals from an extended series of yield data. The objective i...
