Microrganismos eficientes (em) associados à adubação com composto orgânico e remineralizador de solo no cultivo de aveia em solo degradado

Abstract

The recovery of degraded soils is crucial for mitigating climate change and increasing food production. However, the excessive use of chemical fertilizers can cause environmental impacts and create dependence on imports. The solution may lie in the use of soil remineralizers, composting, and efficient microorganisms. This study aimed to examine the impact of various organic fertilizers and different sources of Efficient Microorganisms on the emergence, vegetative growth, grain production, and biomass production of oats. A factorial scheme (3 x 4) + 2 was used in a Completely Randomized Design, evaluating fertilization with an organic compound, an organomineral compound, and a soil remineralizer, when exposed to the application of Efficient Microorganisms from the forest, bamboo, and the commercial product, in addition to the absence of application. In addition, the application of fertilizers without the application of microorganisms was explored. The control groups were chemical fertilization and the absence of fertilization. The results indicated the potential of the organomineral compound as an alternative to chemical fertilization, highlighting the viability of using remineralizers to enrich organic compounds. Inoculation with the commercial product did not show significant improvements. Inoculation with the Efficient Microorganisms from the forest and bamboo demonstrated toxic effects on the system, at the dosage and time of inoculation used in this work.
