Abstract

The application of micronutrients in the soil, in a homogeneous way, with the least contact with soil particles may increase its agronomic efficiency. Storing a solution of fertilizers in a solid porous medium, which is used as a vehicle for application, links great homogeneity to low soil contact. The Solid Capillary Support for Fluid Fertilizers (SC) was used as porous solid medium. It is a compacted cylinder made of gypsum (CaSO4 2H2O), developed experimentally by ULTRAFERTIL. The SC was an efficient way in supplying micronutrients, resulting in similar or better yields in relation to direct application in the soil.
