How to increase nutrient use efficiency in maize fertilization

 

This field trial's goal was to determine the best coating-ratio and the N level for maize, compared with fertigation, and to test the influence of CRF application methods

Conclusions

Summary

In this experiment the application method had the highest impact on the Nutrient Use Efficiency, where the impact of the coated/uncoated ratio was minor.

the application of the nutrients via banding combined with the 25% coated N product seems to be the most efficient way to match the nutrients release pattern with the plants N demand, minimizing the N losses and reaching the highest N-NUE
