Uso de técnicas sustentáveis para remineralização de solos tropicais

Abstract

The combination of rock rock and biofertilization technologies can be used, in a combined way, to increase the availability of nutrients and to revitalize soils in tropical regions. This work aims to present, particularly for the Bahian agricultural sector, a compilation and analysis of the state of the art on these two technologies - which represent sustainable alternatives to enable soil remineralization. For that, we used: a) analysis and interpretation of available databases, aiming at identifying areas with potential occurrences of multinutrient silicate rocks and the demand of remineralizers in the State; b) compilation of knowledge related to agronomic efficiency tests of remineralizers, and c) association of the concepts of remineralizers and biofertilization, discussing the mechanisms through which the combination of these two technologies can accelerate the release of nutrients to the soil. Throughout the work, the advantages of using these techniques were analyzed and demonstrated, as well as the benefits to plants and, by extension, to the food produced, to living beings and, mainly, to the environment. It is important to highlight that the combination of these techniques is capable of promoting the maintenance of soil fertility over time and reducing expenses with imported inputs.
