ENVIRONMENTALIMPACT FOR THE INADEQUATE USE OF CHEMICAL FERTILIZERS IN CULTIVATIONS OF THE CORN

Abstract

The objective of the present investigation was to identify the application of chemical contaminants, which farmers use and the frequency of application in the cultivation of corn. The field methodology was used, samples were taken from water sources. The results indicate that there are between 1,500 and 2,000 hectares planted with corn and the average production in quintals per hectare is between 51 and 100, the quality of the soil is regular. In the identification of surface water chemical contaminants, the results indicate that the maximum permissible limit, according to the standard of the unified text of the secondary legislation of the Ministry of the Environment, took into account; for waters for human consumption and domestic use that only require conventional treatment, here it can be seen that the result obtained is less than 0.01000, the paraquat has values ​​less than 0.1 and the glyphosate itself has values ​​less than 0.001, which indicates that the waters of the river still do not present a high contamination.
