Arbuscular Mycorrhizae for Sustainable Cul-Tivation of Grasses in Regenerative Agricul-Ture

This study focuses on solving rural problems, sustaining environmental conditions, improvement of pastures, and reduction of CO₂ concentration, suggesting inoculated vegetation types found in the tropics as a nature-based solution for degraded agroecosystems, besides for use as cover crops in regenerative agriculture Noninoculated plants are intensively used for revegetation of degraded and mined lands, as well as for for arbuscular mycorrhizae (AMF) taxonomic and plant-fungal ecological studies. Among those grasses, Urochloa brizantha is a tropical forage, having vigorous deep roots, commonly used (AMF) multiplication in glasshouse and nursery, developing infective propagules to be conserved in germplasm banks. Other grass species, such as Urochloa decumbens, is also used for arbuscular mycorrhizal multiplication in addition to its cultivation for sustainable livestock systems. In the present study, a site of 100 m² was selected to take soil samples in a plain area, with U. brizantha pasture, and the soil chemical characterization, microcharcoal content and AMF spore identification, were evaluated 3 + 6showing high amount of potassium (K), high microcharcoal content and the occurrence of 11.32 spores of AMF, most of Glomeraceae, in the rhizosphere of U. brizantha. Due to its economic importance for sustainable agricultural production and other uses besides its environmental services, as important promoters of soil carbon on grazing lands, more detailed research is needed on the biotic interactions and inoculant production of the studied grasses.
