Although herbicides are essential for global agriculture and controlling weeds, they impact soil microbial communities and CO2 emissions. However, the effects of herbicides, tillage systems, and nitrogen fertilisation on CO2 emissions under different environmental conditions are poorly understood. This review explores how various agricultural pract...
Winter wheat (Triticum aestivum L.) is one of the most important crops in the world. Due to the changing climate conditions, winter wheat yield becomes more hectic. The goal of this study is to compare and analyze the Normalized Difference Vegetation Index (NDVI) values derived from the GreenSeeker handheld crop sensor and MicaSense RedEdge-MX Dual...
The EU aims to reduce chemical pesticide use by 50% by 2030. To achieve this, it's crucial to monitor the temporal and spatial effects of pesticides on weeds in various crops. Syngenta Ltd., in collaboration with researchers, plans to use UAVs to monitor the impact of five herbicides in two tillage treatments (Conventional and Conservation) during...
Site-specific management requires the identification of treatment areas based on homogeneous characteristics. This study aimed to determine whether soil mapping based on apparent soil electrical conductivity (EC a) is suitable for mapping soil properties of fields with topographic heterogeneity. Research was conducted on two neighbouring fields in...
More exact information on soil nutrient management is crucial due to environmental protection, nature conservation, decreasing sources for mining, general precaution, etc. Soil magnesium (Mg) analytical methods of potassium chloride (KCl), Mehlich 3 (M3), water (WA) and cobalt hexamine (CoHex) extractions are compared with an elemental analysis and...
This work aims to compare and statistically analyze Normalized Difference Vegetation Index (NDVI) values provided by GreenSeeker handheld crop sensor measurements and calculate NDVI values derived from the MicaSense RedEdge-MX Dual Camera, to predict in-season winter wheat (Triticum aestivum L.) yield, improving a yield prediction model with cumula...
Within the soil spectroscopy community, there is an ongoing discussion addressing the comparison of the performance of prediction models built on a global calibration database, versus a local calibration database. In this study, this issue is addressed by spiking of global databases with local samples. The soil samples were analysed with MIR and XR...
Understanding the role of natural drivers in greenhouse gas (GHG) emitted by agricultural soils is crucial because it contributes to selecting and adapting acceptable eco-friendly farming practices. Hence, Syngenta Ltd. collaborating with researchers, aimed to investigate the effect of two tillage treatments, conventional-tillage (CT) and minimum-t...
Agriculture faces several challenges to use the available resources in a more environmentally sustainable manner. One of the most significant is to develop sustainable water management. The modern Internet of Things (IoT) techniques with real-time data collection and visualisation can play an important role in monitoring the readily available moist...
Phacelia tanacetifolia, an excellent cover, green manure and honey crop is now widely cultivated throughout the world. One of its principal European seed production regions is north-western Hungary, where the recent withdrawal of a potent herbicide, linuron, created a new challenge for many growers. The goal of this study is to identify the main fa...
The current study compares the phosphorus (P) analysis methods of ammonium lactate (AL), Mehlich 3 (M3); water extraction (P-WA(P)&P-WA(PO4)), cobalt hexamine (CoHex) and X-ray fluorescence (XRF) as an estimate of total soil P. The ratio of the P-content/XRF was first calculated and compared with the whole dataset. Based on the comparison of all th...
Understanding the roles of natural drivers in greenhouse gas (GHG) emissions of arable fields is crucial for adequate agricultural management. This study investigated the combined effect of two tillage treatments (NT - no-tillage; CT - tillage with mouldboard ploughing) and environmental (air pressure, air temperature) and soil factors (total organ...
Zn is an essential micronutrient involved in a wide variety of physiological processes. Soils are tested for zinc in many countries with several extractants. Each country has its validated methods, best-suited for its soils. The current study was designed to compare different zinc content measuring methods with seventy-one samples from Hungary. The...
The purpose of the present paper is Authors aim was to deliver a compilation of to summarize the Hungarian soil analysies methods and theas well as to present the advisory system for nutrient management advisory system. Both of them are based on several decades of work. We need to should learn from these past experiences of reasonable and good agri...
Agriculture, Forestry, and Other Land Use (AFOLU) sectors have been responsible for
24 percent of the global anthropogenic greenhouse gas emission (GHG emission) in
2010. GHG emissions from agricultural production were estimated at 5,4 – 5,8 GtCO2 in
2010. The volume of nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2) are
the most releva...
Az élelmiszerek feldolgozási fázisa során sokféle hulladék, melléktermék keletkezik, melyek jó része értékes biológiai anyag, hasznosításuk ezért számos előnnyel járhat környezetvédelmi, fenntarthatósági, gazdasági értelemben. Ennek ellenére jelenleg kevés figyelem irányul erre a területre, a szabályozás sokszor nem segíti a megfelelő hasznosítást....
