Influence of cover crops on citrus crops on arbuscular mycorrhizal fungi development in the Colombian piedmont Oxisols
Native arbuscular mycorrhizal fungi associated with grass and legume cover crops established on Oxisol soils in the Colombian piedmont (Meta) were identified morphologically and the ability to colonize was evaluated. The experimental area consisted of cover crops Arachis pintoi (CIAT 18744), Brachiaria brizantha cv. Toledo, B. dictyoneura cv. Llanero, Desmodium ovalifolium cv. Maquenque, Panicum maximum (CIAT 36000), Paspalum notatum, and a chemical control (Glyphosate and mechanical control) established in the rows in a Valencia orange grove.
