O uso de água residuária e composto orgânico no cultivo do algodão a partir de uma visão socioambiental.

Abstract

The process of development and reproduction of urban space by societies has been occurring in way disordered in the whole planet, to point of cause irreversible environmental impacts. One alternative between so many, is the planned agricultural use of wastewater and organic compound originating from urban solid residues. To meet the premises initially proposed we conducted an experiment vegetation house in the facilities of UFCG and having as a guiding research, the cultivation of cotton herbaceous, variety BRS sapphire, whose fibers have a reddish brown shade, naturally colored using two variables, wastewater and organic compound, both from domestic origin. The research had as base of philosophical sustentation, a work gone back toward an environmental perception, initially using as instrument, a cooperative of collectors of Esperança-PB. As result was verified that in relation to the positive aspects of work in the cooperative, 53% of the interviewees affirmed that the most important in the plant is capable of maintaining the family dignity. While 29% said that gaining insurance, same being little, is what more stimulates the permanence in this work type. In relation to the cultivation of cotton was found that in the conditions that the experiment was developed, the organic substratum and wastewater can replace the chemical manuring, once the production of the plants treated with these variables did not differ from that received chemical fertilizer.
