CARRIZO, M. E et al. Rendimiento de maíz y cambios en propiedades edáficas luego de la aplicación de efluentes líquidos porcinos. FAVE. Secc. Cienc. agrar. [online]. 2014, vol.13, n.1, pp.51-62. ISSN 1666-7719.

CORN YIELD AND CHANGE IN SOIL PROPERTIES AFTER THE APPLICATION OF LIQUID SWINE WASTEWATER The aim of this paper was to assess the effect of the swine effluent application on the corn production and some chemical and physical properties of an Argiudoll of the center of Santa Fe. A field experiment was carried out applying three rates of swine liquid effluent in a randomized complete block design with three replications. No changes were observed on crop density from the beginning to the end of the experiment. The crop productivity increased notably due to the swine effluent application and the highest yield was obtained with the intermediate rate. Soil chemical properties showed some changes related to swine effluent application while the physical properties did not show significant changes, with the exception of soil mechanical resistance. More research and continuous monitoring of the soil chemical properties are needed in order to minimize potential risks of environmental contamination and toxicity over plants.
