Interacción Suelo, Planta, Animal en el Contexto de Dos Sistemas Productivos Desarrollados en Ambientes Ecológicos Diferentes

Abstract

In the search for more biologically and economically sustainable production systems, the understanding of soil-plant-animal interaction seems to be a relevant element when making decisions. That is why in this work it is proposed to know the relationship of land-plant-livestock, emphasizing the evaluation of some components in a systemic way, as well as the effect that grasslands have on the quality and productivity of the cow. The UPSE production system is located on the extension of the Faculty of Agricultural Sciences of the Peninsula de Santa Elena State University, located in the Manglaralto parish, based on free grazing with Llanero pastures, (Brachiaria dictyoneura). The UTA Production System is located in the Experimental Farm of the Technical University of Ambato, Querochaca Campus, located in the canton of Cevallos, based on rotational grazing with kikuyo (Pennisetum clandestinum) pastures, the parameters of pH and content of Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Iron, (Fe), Manganese (Mn), Copper (Cu) and Zinc (Zn) were sampled in a single soil sample, collected in the pasture area dedicated to cattle grazing of the two systems. the content of Calcium (Ca), Magnesium (Mg), Potassium (K) and Phosphorus (P), in a single plant sample, collected in the area the content of the minerals Calcium (Ca), Magnesium (Mg), Potassium (K) and Phosphorus (P), Urea, and Total Proteins (T.P.) in the blood serum of cattle from the two production systems under study was evaluated. This leads to the conclusion that both grass covers in the case of the two production systems can contribute to generating better responses from the animal components, closing the different cycles that allow grasses and legumes to interact in the soil environment with a direct effect on the grazing animal. This approach to understanding the soil-plantanimal interaction is important in order to contrast the best alternative from the productive point of view and at the same time that can be incorporated by producers into their local agronomic practices.
