Interpretive Summary:

Technical Abstract: Three-year field studies were performed to test the effect of vesicular arbuscular mycorrhizal fungi strains on some microbial and physico-chemical properties of erodible soils. Pot experiments of 42 days duration tested the effect of spores of endomycorrhial fungus from the genus Glomus on the yield and nutrient composition of plants and on the physical properties of erodible soil. Soil samples for microbiological and physico-chemical analyses were taken from 10 cm depth in the experimental field twice each year in April and October. Inoculation of soil with Glomus sp did not affect the yields of alfalfa and winter wheat. Generally, microorganism applied to the soil survived well in the rhizosphere, but did not affect the moisture content of the soil or oxygen diffusion rate, redox potentials and soil aggregate stability in water as compared with their controls. The search for new protection methods for erodible soils is a high priority both in the United States and in Poland. Our research using biological methods is an alternative or complementary approach to conventional agricultural and or amelioration methods. Vesicular arbuscular mycorrhizae can be developed as a sustainable technology to protect erodible soils.
