FOFE

Goal

• Develop methods to reduce N2O emissions from the Danish crop rotation system equivalent to a reduction of 960 tons by 2030 while maintaining yields and avoiding other environmental negative impacts.
• Quantify the reduced N2O emissions from the use of foliar nitrogen application
• Implement weather, satellite, and soil sensor data in combination with AI to optimize N rate and timing.

Plan

• Field plot experiments are conducted at three sites to test foliar fertilizer formulation and strategies
• The fate of foliar applications of N is followed in small scale experiments with application of ¹⁵N labelled fertilizers
• Develop and implement a novel nutrient application algorithm based on sensor data and SoilOptixdata
• Validation of protein algorithm based on data from farmers field experiments
• Evaluate the economic and environmental benefits from foliar nutrient application

Expected results

• Develop methods to reduce N₂O emissions from the Danish crop rotation system by 30% while yields are maintained and other environmental negative impacts are avoided
• Implement the use of weather, satellite, and soil sensor data in combination with AI to optimize N rate and timing
• Quantify the reduced N₂O emissions, the economic and environmental benefits from the use of foliar nitrogen application
