Chemical indicators of soil quality of part of the settlement Gleba II rural Garden Amorés of municipalities Pederneiras and Bauru/SP

Abstract

Historically, the characteristic of the agrarian structure in Brazilian territory is the concentration of land whose use is geared predominantly to the agro-export production, while the peasants, as a rule, are engaged in the production of major foodstuffs. In addition, farmers tend to have poorer access to agricultural credit and technical assistance, which may result in impairment of soil quality, especially in rural settlements. As the soil an indispensable natural resource for the survival of society, need to be in proper condition to perform its primary function: to produce food. Inserted in this context, this project aims to assess the social and environmental conditions and changes in chemical soil quality, caused mainly by inappropriate use Gleba II in Rural Settlement Aimorés Horto, municipalities and Flints Bauru / SP. That settlement was regulated in 2007 and includes approximately 373 lots and a total area of 5432.15 hectares. Result of the process of weathering of the sandstone formations and Marilia Adamantina, Bauru Group, the region's soils are sandy and acidic, which impairs the production and the permanence of families in the countryside. For both, will be work-in 50 batches of field II, where sampling will be done according to statistical procedures. Chemical analyzes will include the following attributes: pH, organic matter, Na, P, H + Al, K, Ca, Mg, V% and CTC, and will be made in the Laboratory of the Department of Soil Soils and Fertilizers of UNESP/Jaboticabal. Social and environmental information will be ascertained through a questionnaire consisting of open and closed questions, to be codified in the form of tables and graphs.
