Impactos ambientales de la empresa florícola Agrogana y su remediación

Abstract

This research, conducted in Agrogana, company dedicated to growing roses for export of flowers, analyzes the application of synthetic nitrogen fertilizers, biol and organic matter, total nitrogen input per hectare year, and leaching Nitrates with the irrigation water drained. The results conclude that during the year 2013 were leached NO3-N 536 kg ha-1 yr-1. Leaching is directly proportional to the amount of water drained and the nitrogen fertilizer apply. To reduce leaching of NO3 -, there has been designed a calculator of nitrogen, which allows the reduction of its excessive application, reducing their losses by calculating the depth of water required by the crop. Other options to reduce the leaching of NO3 -, are the use of slow release fertilizers, retardant molecules nitrification and daily monitoring of the concentration of NO3 -saline soil by suction
