Microbiological and Physico-Chemical Characterization of Soil of an Agroforestry System in Tetela De Ocampo, Puebla Méxic.

The loss of the physicochemical and microbiological properties of soils, it is linked to the use of conventional agricultural practices. Knowledge of partnerships within agroforestry systems helps to establish management practices in order to restore and conserve the environment, preserving their physical, chemical and microbiological characteristics. This investigation aims microbiological identification and physicochemical determination of the soil present in the vegetation an agroforestry system in Tetela de Ocampo, Puebla-México. Was confirmed the presence of 14 plant species, 3 species of grasses are reported with forage use and 11 herbaceous two of which are legumes with forage use. The soil is classified as loam clay, with a Dap of 1-1.3 g cm^-3, with an acid pH, influencing the establishment of certain microbial groups adapted to these environmental conditions. The content of organic matter was predominant in medium scale, the values of total N, P and K were variable in all sampling points. Besides the presence of Pseudomonas, Coliform spp., Trichoderma spp., Penicillium sp., Fusarium spp., Pythium spp., Aspergillus spp., and Rizophus sp. was identified. [ABSTRACT FROM AUTHOR]
