Soil is a natural resource that throughout history has provided sustenance for the population; however, with its growth, the demand for food has increased, putting pressure on this resource and causing damage.
Among the actions to protect agricultural ecosystems and prevent their degradation, the application of organic fertilizers has a significant importance, since it is unavoidable that organic matter does not damage the soil and, on the contrary, can improve it.
Humus can define its productive potential. In this context, animal manures, crop residues, compost and worm humus, among others, are included.
A well-known practice applied worldwide is the use of manure from various animals to restore nutrients to the soil. These have the advantage that in addition to restoring the major elements, they contain a good number of nutrients for the soil. It contains a good number of nutrients for plants.
Another option is compost; in which any organic matter can be used, as long as it is not contaminated.
Worm humus is considered by researchers and producers as one of the best organic fertilizers. The amount of nutrients depends on the chemical characteristics of the substrate on which the worms feed.
A biostimulator is defined as a product containing live or dormant cells of previously selected microbial strains, which are characterized by producing physiologically active substances (amino acids, peptides and vitamins) that trigger metabolic events to stimulate the growth, development and yield of crops.
Another alternative that has gained increasing interest in the ecological management of soils is the gradual introduction of green manures, plants used in rotation, succession or association with crops, which, when incorporated into the soil or left on the surface, are capable of maintaining or improving the physical, chemical and biological characteristics of the soil.
