Determinación de nutrientes que aporta al suelo la biomasa de plantas cosechadas de banano inoculadas con microorganismos eficientes

Abstract

The banana activity during its productive cycle originates large amounts of agricultural residues or biomass, highlighting the discarded leaves, pseudostems, rachis and fingers, which are not technically used. This activity during its productive cycle originates large amounts of plant residues, highlighting the leaves, pseudostems and rachis, which are not technically used. The objective of this research was to determine the amount of nutrients provided by the biomass of plants harvested and inoculated with efficient microorganisms, the following variables were considered: pH, organic matter (OM), nitrogen (N), phosphorus (P), potassium (K), copper (Cu), iron (Fe), magnesium (Mg), calcium (Ca), manganese (Mn), ratios of Ca/Mg, Ca/K, K/Mg and Ca/ K/Mg. The analysis indicated that the pH, OM content, and the value of the nutrients in the soil improved in T1 (BT+ME); the contents of P, Cu, Ca and the Ca/Mg ratio presented highly significant values when comparing the soil analyzes at the beginning and at the end of the investigation. T1 is an alternative to reduce fertilization costs and reduce the negative impact caused by chemical fertilizers on the soil, favoring the sustainability of production.
