Qualitative and quantitative aspects must be considered in the side-dressing fertilization in the cultivation of corn. This study aimed to evaluate in the counties of Votuporanga (SP) and Uberlândia (MG), the effect on productivity of corn using different mixtures of granules in the side-dressing fertilization, containing nitrogen (N) and sulphur (S). In Votuporanga (SP), in an Argisol (120 g kg-1 of clay) were estimated losses through volatilization of NH3-N granules mix consisting of urea (U) + ammonium sulfate (AS) or […]
