Organomineral fertilization and NPK in corn (Zea mays L.)

Abstract

At present, it is remarkable the evident concern with our productive system to attend to the premises of sustainable development, paying attention to the fulfillment of the pillars that base it being of an economic, social and environmental nature. Organomineral fertilizers are a good alternative, being basically composed of a mixture of mineral and organic fertilizers, which present potential for agricultural use, since they tend to have a lower cost in relation to chemical fertilizers, and comes from residues from other productive systems such as Such as the chicken litter, allowing investments in its use and research to meet the growing awareness of production, management and sustainable rural development. The use of organic matter allows a rationalization of the mineral fertilizer, promoting an increase in the cation exchange capacity (T), reducing leach losses and helping to release the nutrients to the plant, contributing to increase productivity. The objective of this work was to verify productivity parameters in relation to the behavior of the use of strictly chemical and conventional fertilization, as opposed to organomineral fertilization, aiming at sustainable development, supply, solubilization and residual effect of nutrients in the soil, reuse of by-products and costs of production.
