However, the environmental factors determining their activity and community structure in different soils are still not fully understood. Here, a bioassay is presented to assess the infectivity of indigenous mycorrhizal communities in twenty soils sampled in

Soil biota can be manipulated to enhance soil nutrient availability and fertility, and to improve plant tolerance to stress and diseases. The potential of beneficial micro-organisms (BM) such as mycorrhizal fungi (MF), legume-nodulating bacteria (LNB), phosphorous-solubilizing micro-organisms (PSM), and bio-control agents for

Maize (Zea mays L. cv. Corso) was used as a test plant. Compartmented cultivation containers coupled with 33P radioisotope labeling of soil P were employed to estimate (1) the distance from the
