AgroRegion together with AgriLab demonstrated a master class on how to save up to 1500 UAH / ha using plant matter that remain on the field. For this, a differential application of nitrogen was carried out to mineralize the straw.
The project was implemented in several stages: to determine the mass of straw in the field, the C: N ratio in the straw and the actual “situation” in the soil, a complex field expertise, satellite monitoring and analysis of yield maps were carried out. Based on the obtained data, a task map was developed for the differential application of fertilizers.
What did you get as a result of this approach?
- Reasonable distribution of a dose of nitrogen depending on the mass of straw. Similarly, you can work with biologies.
- Avoidance of unproductive nitrogen losses, which is especially important for light soils.
- From 5-6 t / ha of barley straw, about 70-80% of macro- and microelements will be available for the next crop.
- Positive effect on soil fertility. More details about the project are in the video.
