Afegir etiqueta | Sumari: | The present research work was carried out in the family Romero’s farm located San Roque neighborhood- El Pangui city, where there is an excessive use of glyphosate to combat weeds in coffee and cocoa crops, delivering as consequence effects on health, soil pollution and low productivity. In order to solve this problem, it was proposed to remedy the soil using the treatment 1: bocashi in biopilas, whose relation was 64/36 (soil / bocashi) and the treatment 2: biopila, considered as control. For treatment 1, the bocashi was prepared with supplies from the zone, which was the biopila added later, delivering thus, the registry of temperature, pH and humidity variables, with the purpose to provide adequate conditions for the development of Microorganisms. This remediation process was carried out in 90 days. At the end of the research, treatment 1 presented a 90% of degradation, while treatment 2 maintained the same concentration. As conclusion it was determined that the bocashi addition showed greater remediation efficiency, contributing to the soil with 4,89% of organic matter. The remediation cost for one hectare is estimated at $ 54,081 under the relationship described before, however, considering the fertilizer quantity that a farmer uses in cocoa crops, it would be necessary to use 800 fertilizer bags to remedy 10.94% to the year, investing an amount of $ 5,600, whose decontamination process of 98.44% would be given in 9 years. |
