Organic agroindustrial waste transformation into vermicompost

Abstract

Organic agro-industrial waste represents a global environmental problem, its management represents a solution by transforming organic nutrients into an inorganic form that can be returnedto the agricultural cycle. The process represented here is in charge of the earthworm Eisenia foetida that presents humic substances in the final product which act by amending the structure of the soil, thus improving the development of the plant. The present work is based on the characteristics faced by a producer of earthworm humus as a basis for the raw material coming from organic agro-industrial waste, where 80–90% of it comes from cattle manure, the challenges it faces is to carry out an adequate management to not contain phytopathological microorganisms, and to comply with physicochemical characteristics according to the regulations allowing it to venture into greenhouses for importation. In the results, the presence of phytopathogens, E. Colli and Salmonella was not found, but twelve units are missing to complete the range for N. Y. An analysis of earthworm leaching is presented which results that can be obtained by washing and directly by dragwhich shows that they can make a synergy to achieve a higher quality of it.
