| Corn silage is a roughage widely used to fill the food deficit caused by the seasonality of forage supply. In addition to being a demanding crop in soil fertility, the harvest exports all the material, increasing the extraction of nutrients. The objective of this study was to technically evaluate the fertilization used in agricultural production units (APUs) that do not carry out soil analysis (SA) prior to cultivation and to estimate the possible financial return of a properly oriented fertilization. The sample consisted of 36 APUs that adopt the non-tillage system, located in nine municipalities in Western Region of Santa Catarina State, Brazil.
