Historically one of the agrarian structure characteristics in Brazil is the land concentration, the use of which is geared predominantly for agro-export production, while the peasants, as a rule, are engaged in the production of key foodstuffs. Moreover, farmers tend to have more difficult access to agricultural credit and technical assistance, which can result in compromising the quality of the soil, especially in rural settlements. As the soil a natural resource indispensable for the survival of society, must be in proper condition to perform its main function: to produce food. Inserted in this context, this research aims to evaluate the environmental conditions and changes in the chemical quality of the soil caused mainly by inappropriate use in Gleba II of the Rural Settlement Horto Aimorés, cities of Bauru and Pederneiras / SP. That settlement was regulated in 2007 and holds approximately 373 lots and total area of 5432.15 hectares. Result of sandstone weathering process of Marilia formations and Adamstown, Bauru Group, the region's soils are sandy and acidic, which impairs the production and permanence of families in the countryside. For that, he worked in 60 lots of plot II, where sampling was done according to statistical procedures. Chemical analysis comprised the following attributes: pH, organic matter, Na, P, Al + H, K, Ca, Mg, V% and CTC, and were held in the Soil Laboratory of the Department of Soils and Fertilizers UNESP / Campus of Jaboticabal. The environmental information was ascertained through a semi-structured questionnaire. From the results...
