Title : Application of vermicompost mixed with inert materials during the development of vegetables and cucurbits in protected systems
Abstract:
The need to reduce or eliminate the use of synthetic fertilizers, used to generate high yields in response to the high demand for food from a constantly growing population with less available arable land, without considering their efficiency, their significant polluting potential, their impact on biological diversity, and soil degradation, has led to the need to promote alternatives that help mitigate these harmful effects. The alternative we have promoted is related to the application of vermicompost (VC) or earthworm humus. This organic fertilizer, obtained from the decomposition process of various organic waste under the action of microorganisms present in the digestive tract of earthworms, is rich in essential nutrients. When applied to soil or plant growth substrates, it offers the following benefits: it improves its structure, increases moisture retention and aeration, promotes microbial activity, gradually releases nutrients, and facilitates their absorption, creating a healthier environment for the roots of plant species. Considering the elements described, and as a result of the use of VC in various crops, we intend to share the experiences gained, as well as the results obtained, regarding the substrates and proportions used, their impact on the development of plant species, savings in water consumption and, finally, their impact on the phytochemical composition of the fruits harvested in each crop evaluated.
