Higher NUE
Optimal Maize Production: Agromaster boosts yield and NUE effectively
Castetis, South of France 2023
8
Key Conclusions
- Higher yields – up by 4% Steered by soil temperature, nitrogen is released according to plant needs and improves yield by extra 530 kg/ha.
- Higher NUE – up by 8% Agromaster is more efficient than conventional N-fertilizers due to its controlled release technology.
- Positive ROI – extra 80 €/ha Yield increase brings extra profit to growers and makes Controlled Release Fertilizers (CRF) a reliable solution to fertilize open field soil grown crops.
Objective
To evaluate the possibility of reducing fertilizer rates in the production of maize grains by using Controlled Release Nitrogen fertilizers, like Agromaster. Agromaster consists of 30% coated nitrogen by using ICL’s fully biodegradable release technology – eqo.x®.

Results
In general, when reducing N rates by 20% the yield is decreasing. However, Agromaster increased both yield and NUE compared to conventional urea when applied at the same rate/ha. The results with Agromaster at the reduced N rates of 20%, showed similar yields to the 100% N rate with conventional fertilizers.
