Microbial Activity in the Agricultural and Forestry System

Soil quality is directly related to the diversity and density of microorganisms present in it, as they perform important functions that promote growth plant species, maintaining soil sustainability favoring increased agricultural production environmental regeneration. With this, objective was describe relate existing their action potentials forestry species. Some species fungi bacteria are able solubilize phosphorus from phosphate sources, releasing it be absorbed by roots, resulting gains crop productivity. Other bacteria, when inoculated seeds, besides stimulating development plants, act biofertilizers fixing nitrogen air (N2). Mycorrhizae constitute a specialized symbiotic association between roots some which fungal hyphae absorb nutrients solution transport them plants. The inoculation with help availability phosphorus, due its low concentration soils, becomes essential supplying nutritional demands plants arbuscular mycorrhizal (AMF) solubilizing among can this function. In relation main forest cultivated Brazil, all have potential benefit associations microorganisms, hence importance knowing, researching increase microbial soil.
