Contrary to what we think, plants can not live without this specialized flora is responsible (each group of these specialized agencies in a given cycle or function) to make available to plant different mineral elements (nitrogen, phosphorus , potassium, sulfur, calcium, etc.), in addition to being too important manufacturers of substances such as antibiotics, vitamins, different types of organic acids, etc. Ultimately are the key to nutrition.
Besides organic matter in soil can retain water and nutrients, acting as a reservoir that will supply the different crops. Improves soil structure, allowing air circulation and water essential to the efficient functioning of the roots, balanced between both substances.
Source of Natural fertilizers
Within natural fertilizers have the organic and mineral origin.
Natural fertilizers of organic origin
Traditionally manure was the fertilizer for excellence. While past data exists of how certain groups like the Templars, but they produced no manure compost. In general terms, the manure should be incorporated directly into the soil, but after composting.
Compost is the result of a series of processes and phenomena (fermentation, oxygenation, pasteurization, enrichment of beneficial microbial flora, etc.) Resulting in a new product out of raw material base (or mixture of substances), free viruses and pathogens, free of weed seeds and enriched with beneficial microorganisms. We can only composted manure or adding other debris such as straw, grass, leaves and fresh prunings, etc. Or even a vegetable compost alone.
Sometimes the compost is enriched with mineral substances, such as rock phosphates, clays, salts of potassium and magnesium, etc. Hence arise organo-fertilizers.
Within natural fertilizers also have the crowd is its greatest use as a base substrate for cuttings, seedlings, pots, small seedlings of trees and shrubs, etc. Special mention worm compost, compost quality produced by the excreta of earthworms in a delicate process.
Natural mineral fertilizers
As epsonita kieserite, dolomitic rock, rock phosphate, calcium carbonate of natural origin such as chalk, marl, ground limestone, potassium salts such as sylvite and kainita, patenkali, etc. Also, some clays and clay such as kaolin, attapulgite, etc..
Fertilizers both organic and mineral origin may be the raw material for the manufacture of liquid fertilizers as well as the correction of deficiencies.
