Abstract


Water has a great importance for the survival of living beings, therefore it is increasingly expressive the search of alternatives which reduce the environmental impact caused by the activities of production, for agriculture, markedly the use of agrochemicals. This work has as objective to develop a study about the cost of implantation and estimative of the effect of the community water supply in the management of agrotoxics based in the soybean, maize, bean and wheat production in small properties in Rio Novo and Santa Luzia, in the municipality of Candói – PR. The methodology of the work was constituted in different steps, including the definition of the place, considering the representative agricultural characteristics for the agricultural model practiced in the small properties in most part of the state of Paraná; definition of model of water supply and prevision of costs, and c) realization of the work of construction of the water supplies in the communities, d) estimative of the effects of the use of water supplies over the reduction of the discharge of residues of the agrochemicals in the places of study. Together with this, it was surveyed the characteristics of the agricultural areas, collecting information about the produced cultures and the phytosanitary treatments applied trough spraying. For the calculation of the risks of contamination in the moment of the supply it was considered characteristic data of the place, besides the information available in the literature. It was verified that the use of community water supply represents an alternative for the management of agricultural sprayer in the stage of preparation of the solution, with potential to reduce the volume of agrotoxics to be released in the environment in the moment of supply of the sprayer. The community water supply presents technical execution of low cost with economical viability for small rural properties.
