Green fertilization as strategy to increase organic matter and recovery of degraded area

Abstract

The implementation of agroecological management aims, in addition to the production of quality
food, to improve soil properties. Conventional farming systems degrade soil, a non-renewable
natural resource, increasing the demand for input external to rural property. In this way, the
present work refers to a report of experience lived in the Professional Masters in Agroecology,
whose objective is to analyze projections, over 10 years, of the effects of consortia of green
fertilizers aiming the recovery of a degraded area through contribution Of residues and possible
increases in organic matter contents and cation exchange capacity. The study area was
divided into 3 subareas: subarea 1 will be cultivated pigeon pea and Crotalaria juncea; in subarea
2, pigeon pea and Leucena and subarea 3, Leucena and Crotalaria juncea. Considering
the contribution of carbon by residues and the soil carbon losses, the projections show that the
management of green manures could increase the organic matter and CEC contents.
