The salinity of the soils in the conception of the quilombola community of cupira-santa maria da boa vista-pernambuco

Abstract

The present study sought to analyze the interrelation between the practical knowledges of the farmers of the quilombola community of Cupira, semiarid of the state of Pernambuco, with the process of salinity of the soils. For the development of this study, the ethnopedology, elements of social cartography and the chemical analysis of soil samples, collected on farmers’ indication, were used as a methodological basis. The results indicate that most farmers recognize easily the occurrence of the salinity process, as well, as impacts on soil structure in the agricultural production. It is concluded that the farmers present practical knowledges to recognize the process of salinity and also, the practices that collaborate for the development of the accumulation of salts, nevertheless, it was verified the need for the sum of technical scientific knowledge and the aid of public policies to solve and avoid problems arising from salinity.
