PHYSICAL AND CHEMICAL ATTRIBUTES OF SOIL CULTIVATED WITH SUGAR CANE FRAGMENT NEAR NATIVE

Abstract

Currently, the countryside is dominated by intensively cultivated areas with large monocultures, bare ground suffering severe erosion, riparian areas without vegetation and small forest fragments isolated and disturbed by human activities. This model proves to be untenable today, with severe and irreversible environmental consequences. This study aimed to characterize physical and chemical parameters in order to explain the influence of native forest fragments on production and quality of sugar cane grown near the fragments and also prove the usefulness of conservation of these fragments. The study was conducted in a fragment at the Center for Agricultural Sciences - UFSCar Campus Araras, São Paulo. To achieve this goal, we evaluated the quality of the soil, through its components: organic matter, pH, P, K, Ca, Mg, S, Al, H + Al, Na, B, Fe, Mn, Zn, m, SB, CEC, V, density, macro and microporosity, at intervals of 5m to 50m away from the forest edge towards the agricultural area, moving into the area cultivated with sugar cane and 10m inside the forest, and soil sampling done in depths of 0-10 and 10-20 cm. The headquarters of forest and cane sugar were very different in relation to soil characteristics. The effects observed in soil cultivated with sugar cane were sharper and more pronounced in the first 20 meters from the forest.
