Description
Summary:Microbial plant biostimulants represent one of the solutions for the negative impacts associated with high residues agricultural systems. We developed a hydro-gelified and film forming formulation, which we used for in situ formation of a bio-composite mulch, by treatment on crop residues. Into this hydro-gelified and film forming composition we included microbial biostimulants strains, Trichoderma asperellum T36 and Brevibacillus parabrevis B50. We tested the effects of application of such microbial plant biostimulant formulation on polyamines and ortosilicic acid release from a mixture of hairy vetch and corn residues, on controlled conditions. We evaluated the influence of crop residues treatment with our formulation on crop yield and soil characteristics - water stable aggregates, glomalin related soil proteins. The results demonstrate that treatments on crop residues with our formulation of microbial plant biostimulants compensates some disadvantages of high residues conservation agriculture, enhancing its effects on soil aggregate stability, due to the promotion of glomalin related soil proteins formation.
