AVALIAÇÃO DOS ATRIBUTOS FÍSICOS DE UM ARGISSOLO VERMELHO-AMARELO COLETADO EM ÁREA DE UVA ENTRE PLANTAS, NAS ENTRELINHAS E EM MATA NATIVA.

Viticulture is an important activity for the sustainability of small property in Brazil. In recent years, it has become important in generating employment in large enterprises that produce table grapes and grapes for processing. Gravatá, located in the Pernambuco agreste, only one property, Sítio Brabo, started in 2016 a vineyard for a small table grape production, Vitis labrusca Cultivar. 'Isabel' which is normally cultivated and has good adaptation to the climatic conditions of southern Brazil. The objective of this study was to evaluate the spatial variability of a YELLOW LATOSOL under different use systems: Native forest and grape growing area with collected soil. between plants and between rows, having as variables evaluated the soil density and gravimetric humidity. The experiment was carried out in Gravatá-PE on Sitio Brabo property. Soil density was made according to the methodology of the Koppeck ring with sharp edges, and the gravimetric soil moisture was obtained with the same soil sample of the ring. The experimental design used was the split plot, where the main treatments were three systems of use: Grape Cultivation (with collection between plants and between rows) and native forest. And the secondary treatments were four layers of the soil profile: 0-10cm, 10-20cm, 20-30cm and 30-40cm. The replacement of native forest by grape cultivation negatively influences the soil structure, over the years the native forest maintains its structure and the grape area presents soil density variation from 0.10 to 0.20m.
