Preparation of biol with an adequate concentration of NPK,4using various sources of organic matter in discontinuous biodigesters

Abstract

The research was carried out with the objective of determining the adequate concentration of NPK in the biol, using different sources of organic matter in discontinuous biodigesters, for this purpose, different amounts of organic matter from cattle and rabbits, plant remains such as beans, watercress, alfalfa and other elements were used, These were processed in hermetically sealed biodigesters for their anaerobic decomposition and to obtain liquid fertilizer (biol). The different concentrations of macronutrients were evaluated for their use in vegetable production as a foliar liquid biostimulant. A completely randomized design with a 2x3 factorial arrangement was used. The variables measured were decomposition time and macronutrient concentration in the sample. It was observed that the biols produced did not show uniformity in terms of pH, conductivity and macronutrient content depending on the raw material used. The results show that the biol samples produced have adequate amounts of macronutrients that will help many crops in their growth and development.
