Key Conclusions
- Higher yields – up by 9%
Steered by soil temperature, nitrogen is released according to plant needs and improves yield – plus 8 mt/ha - Higher NUE – up by 41%
Compared to conventional fertilizers, Agromaster® increases nitrogen use efficiency (NUE). In this trial NUE increase is 41% – i.e. extra 72 kg of onion per kg of N applied - Positive ROI – extra 1,965 €/ha
Yield increase brings additional profit to growers and makes Agromaster® a reliable solution to fertilize open field soil grown crops
