Caracterização físico-química do solo no Assentamento Chão do Amanhã

Abstract

The objectives of the present work were to characterize the soil of Chão do Amanhã agricultural settlement located in Sorriso – MT, aiming to understand the soil profile in this region due to its location and the use of the soil for the agricultural purposes, as well as, providing subsidies for the settlers for an adequate handling of plantations, besides to analyze the current use and occupation of the soil and the agricultural activities developed by the settlers. Composite samples of 0 - 20 cm depth was collected, making up the entire area to be analyzed for the physicochemical characterization. In the physical analyzes, the soil texture was determined. In the chemical analysis, soil fertility analyzes were performed on all collected samples, being: pH in H2O and in SMP and P, K+ , Ca2+, Mg2+, Al3+ and H+ Al contends. It was verified the occurrence of Latosol, differences in the clay and sand fractions between the parts near to the BR 163 and those nears to the Teles Pires River, as well as, variations of macronutrient levels. The fertility of the profiles studied, from medium to high values, allows the maintenance of natural vegetation, from shrubs to large trees, as well as, the cultivation of legumes, vegetables and cereals. Both, geographic location and adequate soil management can infer desirable or not desirable characteristics of their productivity and that, unfortunately, the settlers of Chão do Amanhã Settlement does not yet have a proper attention regarding the treatment of the soil that they use for agricultural production with efficiency.
