CLEANER PRODUCTION: A SUSTAINABLE TOOL IN SOY TO REDUCE THE ENVIRONMENTAL FOOTPRINT OF CONVENTIONAL FERTILIZER USE

Abstract

For a more sustainable agriculture, new agricultural management must be adopted in order to maintain productivity and grain quality while respecting the environment. This study aims to investigate the feasibility of implementing rock dust-based biofertilizers in soybean crops, using the cleaner production program as a basis, aiming to reduce the environmental footprint of the use of conventional fertilizers. To this end, testing in the field this diversity of agrobiological products and managements, thus being exposed to climatic variation, pest and disease attack, in relation to the management adopted. The results showed that when contrasting the chemical and bioagricultural treatments, the latter presented significant results in relation to the variables number of active nodules in R1, NDVI V3, number of grains per pod, weight of one thousand grains, yield in kg/ha and SC/ha.
