Recuperação de pastagens degradadas através da arborização: um estudo de caso no assentamento Santa Maria, Copavi, Paranacity - PR

Abstract

The silvopastoral system is still not very widespreadby most agricultural producers. However, those placed on the market have the opportunity to offer better conditions to the integrated management between soil, forages, animals and forests. The use of this technology becomes more demanded due to the benefits that the system provides such as soil fertility improvements, ananimal’s thermal environment, production diversification, commercial wood income and environmental protection. The objective of the study was to evaluate the improvements promoted by the integrated system of pasture-afforestation in relation to pasture under open field. The study was carried out at the Santa Maria settlement, where part of the area is in desertification process, due to the soil matrix being of arenite origin, associated with the inadequate management of agricultural activities.The activities developed for the recovery of grazing in degraded soils indicate that the implantation of the afforestation in paddocks, together with planting of forage and fertilizers management is promoting the soil and pasture quality improvements. The adoption of integrated afforestation in pastures has the potential to recover sandy soils. The soil quality indicators that most evidenced the potential of afforestation in pastures were the biological activity, soil compaction and water infiltration and organic matter content.
