Thanks to the implementation of this project we optimized the crops nutrient supply, resulting in a reduction of GHG emissions and better field efficiency, with positive effects on the lifetime production of the cows.
In collaboration with Yara
Why does it matter?
Lack of nutrients and Se content in the soil causes fertility and metabolic issues for the crops.
How did we solve this?
Manure can be used as crop nutrition and combined with mineral fertilization increases the nutrient content in forage such as S and Se. In this project, the fertilization plan was defined based on the results of the analysis of the soil. Nitrograss Se fertilizer was used for higher S reducing protein shrinkages and higher Se content.
The results from the project on farm show green yield (ton/ha) increased by 11%. Also, the project provided positive effects on the lifetime production of the cows, increasing the milk index (kg milk/ha) of 17%. Finally, the project brought reduction of GHG emissions. The carbon sequestration (calculated in kg of CO2 eq/ha fixed to the soil) increased by 200%.
Opportunities for other farms?
Strategies to improve soil health can be applied in all farming systems, for all regions and crops. Thanks to a balanced nutrient approach, we can integrate the amount of inputs plants need.
