The evaluation of soil properties allows to know the level of degradation of indicators related to fertility and to have a better understanding of the responses of crops to fertilizer applications, in order to obtain acceptable yields. The present work was carried out with the objective of characterizing the current state of two types of soils dedicated to the production of forage plants for cattle feed. In both soils, their contours were delimited, their profiles were morphologically described and later they were classified. In the agrochemical sampling, elementary plots were delimited by soil type, in which a sample was formed for each one, to which were determined the pH, the assimilable phosphorus, the interchangeable cations, the content and the carbon reserve and They took several samples to determine their mechanical composition, clay dispersion coefficient, natural and hygroscopic moisture, soil density and solid phase density, total porosity and stability of the aggregates. The soils studied were classified as Gley Nodular Ferruginous and Red Brown Fersialitic. In addition, both soil types showed signs of degradation in the upper horizon, reflected by a low carbon content, high dispersion coefficient of clay, low moisture retention, low percentages of porosity, high values in the density of the soil and the density of the solid phase, together with a structure characterized by the presence of medium-sized prismatic blocks.
