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

Abstract

For a more sustainable agriculture, new agricultural management practices must be adopted 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, this diversity of agrobiological products and management practices was tested in the field, thus being able to be exposed to climate variation, pest and disease attacks, in relation to the management adopted. The results showed that when chemical and bioagricultural treatments were compared, 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 a thousand grains, yield in kg/ha and SC/ha.
