N-(n-Butyl) Thiophosphoric Triamide (NBPT) coated urea (NCU) improved maize growth and nitrogen use efficiency (NUE) in highly weathered tropical soil

Nitrogen (N) fertilizer is commonly used to supply sufficient N for plant uptake, for which urea is one of the highly preferred synthetic N fertilizers due to its high N content. Unfortunately, N provided by urea is rapidly lost upon urea application to soils through ammonia volatilization, leaching...
