Influencia del suelo en la calidad de cuatro especies de pasto en cinco localidades del estado de Durango

Abstract

Soil is the substrate where terrestrial plants develop their roots, with which absorb water and nutrients essential for life. Grasses are the most important agricultural plants in the world because they provide the food necessary for growth and reproduction of herbivores. Evaluating the elements present in the forage and its relationship allows us to apply soil conservation techniques and grazing management that lead to greater production and less deterioration of the ecosystem. The objective was to determine the influence of soil on the quality of grasses Bouteloua gracilis, Bouteloua curtipendula, Bothriochloa barbinodis and Melinis repens in the localities of Torreon de Cañas, Los Lobos, El Arenal, El Sagal and Los Adobes, in the state of Durango. Evaluations were made of soil physico-chemical and chemical and botanical composition of pasture. These assessments were analyzed using canonical correlation to verify the degree of association between soil-pasture variables. The results obtained indicate that the fat content of the species is related to the calcium, potassium and cobalt of the soil; neutral detergent fiber with potassium; the magnesium content of the species with the content of magnesium, phosphorus, copper and cobalt; phosphorus and cobalt with manganese content of the soil.
