Growth and yield increases, obtained in nodulated soybeans growing in unamended sterile soil by inoculation with the vesicular–arbuscular (VA) mycorrhizal fungus Glomus mosseae, were accompanied by improved P uptake, lower root to shoot ratios, better nodulation with higher nitrogenase activity, and modifications in the pattern of the latter during plant growth. Stimulation of nitrogenase activity occurred early in plant development and preceded plant growth responses by about 2 weeks. Phosphate fertilization increased yield, percent P but not percent N of both mycorrhizal and nonmycorrhizal soybeans, and also modified the pattern and amount of nitrogenase activity during plant growth. Additions of 0.25 g KH2PO4/kg to the soil eliminated the mycorrhizal effect on plant growth, but nodule formation and nitrogenase activity were still significantly stimulated by the mycorrhizal infection. Mycorrhizal effects on nodulation were eliminated with 0.5 g KH2PO4 and on nitrogenase activity with the addition of 1.0 g KH2PO4. These higher levels of phosphate fertilization considerably diminished infection and, in particular, fungal spread within the roots.

Vesicular Arbuscular

Vesicular-arbuscular mychorrizae (MVA) is a key player in triggering vegetation development and soil reinforcement due to its potential to increase plant growth and soil aggregate stability. In terms of enhancing plant growth, the vesicular-arbuscular mycorrhizae provides greater and more efficient access through the fungal hyphae for nutrient absorption and delivery to the plant. From the side of soil mechanical, the potential of vesicular-arbuscular mycorrhizae is to increase the soil aggregate stability. These potentials, in their application can contribute to soil and slope stability. The characteristics and biological effects of vascular-arbuscular mycorrhizae to increase plant growth and soil aggregate stability in the correlation to slope stability will be discussed in this paper.
