Atributos físicos e químicos de qualidade de solos do engenho Várzea do Coaty sob uso com bananeira, sabiá, pastagem e mata nativa

Abstract

Less environmentally aggressive crops have taken on global strength and proportions, producing production systems such as Agroforestry Systems and Integration of Livestock Crop Forest. The work evaluates the physicochemical state of the Engenho Várzea do Coaty soils under the use of banana, thrush, Piatã grass and forest reserve; In addition to analyzing the method of production and management of soils, it classifies the risk of degradation, nutritional support, physical structure and soil classes (which best represents). The research is exploratory-descriptive, with a total of 16 composite samples collected at depths (0-20 cm) and (20-40 cm), and divided by bands of the same relief, distributed in the forest reserve areas, control group, and banana, forestry and grassland crops for physical and chemical analysis; In addition to these, 3 simple samples were collected to consider the soil classes. Red-Yellow Argisol (in loco analysis), Eutrophic Cambic Red-Yellow Latosol and Typical Tautic Eutrophic Melanic Gleysol, with acid pH, medium fertility and satisfactory organic matter content were verified. The texture is sandy clay loam, except in the lowland / pasture and lower third of hill / savanna areas; with better stability on the horizon (0-20 cm). Therefore, soil correction should be performed by liming and fertilization specific to each type of crop, by calculating the liming recommendation; In addition, it can use modern production systems such as Forest Livestock Integration through a forested banana consortium, and forested pasture to promote synergy between the planted crops.
