| Replacing the traditional fall-winter fallow with cover crops in irrigated cropping systems might enhance soil quality properties, like the development of arbuscular mycorrhizal fungi (AMF). Increasing AMF is often associated to improvements of soil structure, water retention, nutrient absorption and crop productivity. This work studied the effect of two winter cover crops on different parameters related to AMF measured during cultivation of irrigated maize in Aranjuez (Madrid, Spain) under semi-arid Mediterranean climate. Twelve plots were randomly distributed in four replications of three treatments: barley (Hordeum vulgare L.) and vetch (Vicia villosa L.) as cover crops during the fall-winter period and bare soil as control. Samples of the root system and soil from the rhizosphere were collected at 54 and 69 days after sowing maize. The direct variables measured in the samples were mycorrhizal colonization, hyphae length of extra-radical mycelium and number of AM fungal spores. Also, easily extractable glomalin related soil proteins (EE-GRSP) and ?-Glucosaminidase activity were determined as indirect variables. | |
