Plant fertilisation is a very important yield-forming factor. It also accounts for a large proportion of farm costs. In addition, it can make a significant contribution to groundwater pollution and emissions. The workshop “Efficient Nutrient Management in Field Crops” will provide an overview of tools to reduce the use of fertilisers, which will contribute to reduced costs for farms, lower energy inputs for field production, and significant reductions in emissions when using nitrogen fertilisers. The target group is interested farmers, agricultural consultants, representatives of agricultural schools, universities, chemical-agricultural stations, and all interested parties.
