Field efficiency
Thanks to the implementation of this project, we optimized crop nutrient supply, improved field efficiency, reduced GHG emissions, and also improved cow lifetime production.

Why does it matter?
A lack of nutrients and Selenium (Se) content in soil causes fertility and metabolic issues for crops.
How did we solve this?
Manure can be used to provide crop nutrition and can be combined with mineral fertilization to increase the nutrient content in forage, such as increased levels of Sulphur (S) and Selenium. For this project, the fertilization plan was defined by calculating a baseline reading, based on soil assessment results. Nitrograss Selenium fertilizer was used in a tailored approach to increase Sulphur and to reduce protein shrinkages, and to increase levels of Selenium.
This project resulted in green yield (ton/ha) increasing by 11%, a positive effect on cow lifetime production and an increased milk index (kg milk/ha) by 17%. Finally, the project brought about a GHG emissions reduction. The resulting carbon sequestration (calculated by 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. By adopting a balanced nutrient approach, farmers can calculate and integrate the amount of nutrient inputs that plants need.
