N-NH 3 Daily Volatilization Rate (DVR) (a) and N-NH 3 Accumulated Volatilization Rate (AVR) (b) based on the treatments applied in the second side-dressing fertilization, 52

The purpose of this study was to compare the influence of urea coated with sulfur or with boric acid and copper sulfate, and of conventional nitrogen fertilizers on nitrogen losses

Nitrogen application had a favorable effect on N concentrations in leaves and grains, Soil Plant Analysis Development (SPAD) chlorophyll meter readings and on grain yield, where

We evaluated urea-based N fertilizers treated with coating technologies, i.e., coating with boric acid and copper sulfate - UCuB (N = 44.6 %, B = 0.39 % and Cu = 0.16 %) and

Daily N-NH 4 + volatilization rate from the evaluated nitrogen fertilizers: U_Z-i, urea+zeolite incorporated; U_NBPT-i, urea+NBPT incorporated; U_S-I, urea+elemental

This study aimed to evaluate nitrogen losses by ammonia volatilization from stabilized, slow and controlled release urea and its absorption by maize grown under no-till in an

Therefore, when planning for nitrogen fertilization, one should consider many factors, such as the cost of fertilizers and staff for fertilizer application and the fact that the use
