Abstract

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.

Abstract

Plant roots and litter produced by tree that grow have an important role in the entry of rainwater into the soil (infiltration) as water storage in the future. The effects of plant roots and litter on increasing infiltration rate is due to increased soil macroporosity. The presence of roots that spread in various layers in the soil profile will further increase the organic matter content of the soil and loosen the soil thereby increasing soil macroporosity. In addition, dead roots will form empty spaces that can be filled by infiltration water, as well as active roots that have gaps between roots and soil that can be filled infiltration water. The high infiltration rate will reduce the amount of excessive runoff water so as to reduce the occurrence of erosion.
