- ÍtemEfecto, en el corto plazo, de la porcinaza en suelos. Estudio de caso desde diseño de experimentos en algunos municipios de Valle y Antioquia(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Ruiz Ramírez, Diana María; Zambrano Moreno, Gregorio Salomón; Fonseca Gómez, Lida RubielaThis work has the objective of analyzing in the short term the effects of the application of the porcinaza as fertilizer in the soils of some municipalities of the departments of Antioquía and Valle del cauca. For this, an experimental design was carried out using a parametric factor analysis and a non-parametric analysis with the Kruskal - Wallis test. The experiment consists of the following treatments: SNF (Unfertilized soil), SSF1 (Fertilized with porquinaza 2 months after application), SSF2 (Fertilized with porquinaza 4 months after application). Samples were taken in six experimental farms, three in each of the analysis departments. The samples were taken at two levels of depth, the first from 0 to 5 cm and the second from 5 to 30 cm. Having a total of 108 replicates for the experiment. With the application of swine as a fertilizer, significant differences were found in variables such as nitrogen and phosphorus, going from 18.16 (ppm) parts per million to 29.16 (ppm) at a depth level of 0 to 5 cm and from 14.22 (ppm) to 20.02 (ppm) at a depth level of 5 to 30 cm in the case of nitrogen, showing evidence of significant change. For phosphorus a change from 236.06 (ppm) to 314.83 (ppm) was found at a depth level of 0 to 5 cm and from 67.86 (ppm) to 167.58 (ppm) at a depth level of 5 to 30 cm. The above variables are considered as macro nutrients that help plant growth. It is concluded that porcine fertilization does have effects on the chemical and physical characteristics of the soil.
