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®.
