<p>The Organic Fermented Manure richness, is determined by the micro - organisms population it presents, which depend mainly on temperature, pH, humidity, oxygen and food. This conditions change between a biol, bocashi and the floor; because in this one the populations that can be found are not the same as the AOF´s populations. In consequence, the contribution of such manure is food to the plants starting out of the incorporated minerals as sulfates, phosphates and carbonates, and out of the mineralizationsteamification of the organic substance. It is also a nutrient to the micro organisms that use these minerals and to the organic molecules. The percentage of organic substance transforms itself into: food source for the actinomicets, carbon for free life nitrogen fixers, inorganic phosphates for soluble-makers of this compound and other present organisms in the enviroment.</p>
