Nutritional requirements is one of the most important factors in the maintenance of soil fertility, weakening the morphological and botanical development of plants, thus achieving a long or medium term decrease in the yield percentage of agricultural production.

▶ Traditionally, nutrient deficiencies, especially nitrogen (N), are corrected through the addition of inorganic fertilizers; where a large amount is used, which, in the eyes of the producer, notably increase the productivity of his crops in the first years.

However, this production will not be sustainable in time, due to different factors that alter this synthetic incorporation and abuse of the same; causing sterility to the edaphic factor due to the decrease or destruction of the microfauna and microflora present in a natural way, which brings as a consequence an environmental impact.

It is for this reason that greater awareness has been raised and a strategy of nutrient supply to crops (perennial and short cycles) has been adopted, integrating the application of organic fertilizers, to reduce the damage caused to the environment, human and animal health by the irrational methods that have been used in recent decades.

In view of the situation described above, it is necessary to evaluate the effect of organic fertilization on perennial crops as well as on short-cycle crops, in order to avoid further deterioration of the microfauna and microflora populations present in the soil.

With the application of organic fertilizers such as worm humus, this biological product can be evaluated on crop yields and its physical, chemical and organoleptic characteristics, comparing it with a chemical fertilizer, giving to observe the benefits and disadvantages that could cause any of the fertilizers to the microfauna and microflora present in the soil.
