ORGANIC FERTILIZERS

There are a wide variety of products that can be used as organic fertilizer. According to their sources are natural and manufactured.

When speaking of compost produced referred the different types of compost that may occur, including those that is reinforced in an effort to improve their quality.

Compost

The compost is an aerobic decomposition of the organic substrates in the presence of oxygen. The main products of bio

logical metabolism are

CO2, water, ions, minerals, organic matter stabilized (humus) and heat.

Benefits Composting

Composting has the advantages of transforming th

e heterogeneous organic material to a material more homogeneous and stable, reducing the

volume and mass of primary materials.

The final product is free of odor, it is

easy to use and can be stored for long periods of time. Composting destroys pathogenic organisms from humans and plants, seeds of weeds, insects and insect eggs and is used as a valuable “conditi

oner” in the soil.

Compost is an excellent soil improver in

its physical, chemical and biological characteristics.

Factors for a good process

The principal factors to get good results are: ox

ygen, temperature, Humidity, Carbon / nitrogen (C / N), Degree of acidity (pH Particle size, stabilize step and storage.

Material to be used for the compost

The ingredients for the compost will be available organic materials that are generated after any activity or culture.

You can use in agriculture: crop and garden residues, parts or pruning, manure, the litter of coffee, waste of bananas, pineapples, such as co

rn stubble or beans, sugar cane biogases, and others.

And DO NOT USE THE FOLLOWING MATERIAL: products with chemical residues Weeds with ripe seeds motor oil. feces of dogs or cats. Toxic materials such as gasoline, diesel, turpentine, can fin and motor oil.

The use of the compost depends of the composition of the ma

terials from which it is made. Each type of compost will have a specific value of fertilization, which can be taken into account in the calculations of fertilization.

Another very viable alternative when you have the knowledge and experience, as well as the physical and technical conditions necessary to transform organic waste and good quality of product is with earthworms, which allow for excellent.
