Diagnóstico da regeneração natural e qualidade do solo na área de reserva legal da fazenda cristalina após a implantação de espécies florestais nativas

Abstract

Natural regeneration is the oldest and most natural form of renewal of a forest. All tree species have mechanisms that allow its perpetuation in the natural system. Natural regeneration is an important element in the evolution of a tree species and is closely correlated with the environment in which species developed, as well as the biocenosis that evolved Natural regeneration is one of the recommended methods for forest restoration in Permanent Preservation Areas Legal Reserves and the National Council of the Environment (CONAMA) and is the best strategy for areas with small degree of disturbance. Natural regeneration occurs through the gradual replacement of different plant species, so that sufficient leave the area to be restored so that it recovers naturally. In some cases recovery occurred faster if already available remaining young individuals, seed bank and / or regrowth of plants by the roots. So, we tried to work with this diagnose natural regeneration and soil quality in the Legal Reserve area of Finance Cristalina after the introduction of native species inoculated with mycorrhizal fungi. The study was conducted at Fazenda Cristalina in São Domingos do Araguaia, in the Biomes Project, in an area of 0,64ha. Soil fertility of Legal Reserve Area Crystal Farm is a limiting factor for the good development of seedlings of native forest species and their natural regeneration since regeneration is occurring slowly, due to the dominant presence of braquiária and braise fish and lack of silvicultural management in the area. The soil organisms found in soil samples of the experimental area, show that the soil is in the process of rehabilitation.
