Yield increase
Reduction of N rate by 20% while maitaining high yields is possible when using controlled release fertilizers.
Slupia, Poland 2023

Key Conclusions
- Higher yields – up by 12% Steered by soil temperatures, nitrogen is released according to plant needs and improves yields by extra 6.8 mt.
- Higher NUE – up by 65% Agromaster® is more efficient than conventional N-fertilizers due to its controlled release technology. Every kg of nitrogen applied with Agromaster® provided extra 53 kg of potatoes..
- Positive ROI – up to 1,000€/ha extra Yield increase brings extra turnover per ha and makes Controlled Release Fertilizers (CRFs) a reliable solution to fertilize open field soil grown crops.
Objective
To evaluate the possibility of reducing fertilizer rates in potato production by using Controlled Release Nitrogen fertilizers, like Agromaster®. Agromaster® consists of 60% coated nitrogen by using ICL’s fully biodegradable release technology – eqo.x®.
