RESUMO:

The present study aimed to provide a scientific basis for the use of organic residues from a sewage treatment plant, enriched with phosphorus and potassium as an organomineral fertilizer (FOM) in agriculture, identifying the best proportion of nutrients to be adopted for cultivation in systems organic. For that, the specific objectives were the elaboration of the FOMs containing in their composition P and K; testing in laboratory conditions of FOMs, in contrast to the use of constituent fertilizers in isolation, regarding the dynamics of release and losses by leaching of N, P and K from FOMs; evaluation, in a greenhouse, of the corn response, as a test plant, regarding the application of the selected FOMs in the laboratory; evaluation of the residual effect of applying the FOMs to the soil after cultivation.

The present work is organized in two chapters. In chapter 1, entitled “Formulation and granulation of organomineral fertilizer and evaluation of fertilizer efficiency”, the sources used for the production of the compound FOM, as well as the formulations from these were characterized. The dynamics of nutrient release considering the particularities of organic fertilizers, as well as the effect of the use of FOM on the loss of nutrients by leaching were also evaluated. In Chapter 2, entitled “Agronomic efficiency of compound organomineral fertilizers from permitted sources for organic agriculture”, the agronomic performance test of FOMs and the effect of their application on the dynamics of nutrients in the soil is presented.
