- •
Fertilizer mixture of controlled-release urea (CRU) and normal urea increased crop yield, NUE, and net farm profit, compared with normal urea.
- •
Release rates of CRU in water and soil were investigated.
- •
Releases rates of N from fertilizer mixture corresponded well to the N requirements of wheat and maize plants.
- •
Fertilizer mixture reduced the leaching of inorganic nitrogen from the crop root zones, compared with normal urea.
