El impacto de la ganadería y la agricultura en los ecosistemas terrestres.-Valorización agronómica de purines para su utilización en común

Abstract

ABSTRACT Due to the intensification of livestock production and the concentration of holdings in specific areas, has disrupted the balance between production and utilization of swine waste in agriculture. Given the volume of slurry generated in Murcia, and the total cultivable area and considering the legislation, RD 261/1996, which allows a maximum application of 170 kg N / ha / year in areas designated as vulnerable, it is estimated that to implement the slurry generated in the region in a year, would require only half the arable land devoted to irrigation. In this way, this study has included detailed monitoring of the effect of the application of pig slurry at a concentration recommended on the properties and chemical, physical and biological properties of soil, water and plant to determine the influence of slurry on the reserve of organic matter in each of these crops, as well as contaminated soils, through the creation of a pilot system for managing livestock waste in accordance with preventive measures that allow for their optimal use, without risk of contamination for the system watersoil- plant.
