Crops adapt to different agroecological conditions, which is why research results or practical experiences have been extrapolated from one locality to another without considering the possible consequences that may occur in the short, medium and long terms, according to the fragility of the environment where said crop is going to be exploited.
In this sense, when the farmer's management of his lands for production is oriented to copy external models with the use of synthetic products, costs increase and can cause an imbalance in ecosystems in the medium or long term, which translates into a productive decrease of agroecosystems. This means that there are two production approaches, one with the use of organic fertilizers and the other with the use of inorganic fertilizers.
In this same vein, Vera, Cepeda, Cárdenas, Espejo, Granda, Inga, Balón and Delgado (2020), point out that corn producers recognize that the appropriate applications of fertilizer in the plant are necessary to obtain high yields, however, the dilemma is to recognize that the dose to be applied since, the fertilizer that is not used produces economic damages and environmental damage.
For the aforementioned reasons, it is necessary to mention that there are various ecological fertilization alternatives known as organic fertilization that allow to correct these aforementioned problems, regardless of the appearance that said organic fertilizer presents; that is, whether it is in a solid or liquid form, but sometimes the dose that can be established in different crops of tropical zones is unknown.
Using organic fertilizers, brings with it different benefits such as the reduction of the indiscriminate use of synthetic fertilizers avoiding the pollution of water sources and improves soil fertility, in addition, according to those reported by Torres and Medina (2009), these fertilizers have the minerals that plants need for their development among these organic fertilizers we must mention the biol, which is presented as a good biostimulant, which helps in the growth and development of crops, and is produced in an artisanal or natural and economical way, because its preparation is based on materials found in the field such as manure, water, among others (Chacón, 2011).
With the use of organic fertilizers such as biol or vermicompost in agricultural ecosystems, organic matter can be contributed to the soil, which favors the retention of water and nutrients, improving the structure and biological activity of the soil. In addition, the microorganisms present in these products decompose organic matter and release essential nutrients for plants, such as nitrogen, phosphorus and potassium, in assimilable forms. The continuous use of this type of ecological product contributes to creating a healthier and more fertile soil, which benefits the growth and development of crops.
Dear readers, establishing this type of agroecological alternatives would be of great relevance for small and medium-sized producers, therefore, all efforts should be made to direct research that shows that this approach to conventional agriculture can be progressively replaced.
