Arbuscular mycorrhizal fungi are most frequent in plants growing on mineral soils, and are of extreme importance for plants growing in nutrient-deficient substrates such as in volcanic soil and sand dune environments . The populations of AM fungi is greatest in plant communities with high diversity such as tropical rainforests and temperate grasslands where they have many potential host plants and can take advantage of their ability to colonize a broad host range.  There is a lower incidence of mycorrhizal colonization in very arid or nutrient-rich soils. Mycorrhizas have been observed in aquatic habitats ; however, waterlogged soils have been shown to decrease colonization in some species.  Arbuscular mycorrhizal fungi are found in 80% of plant species  and have been surveyed on all continents except Antarctica.   The biogeography of glomeromycota is influenced by dispersal limitation,  environmental factors such as climate,  soil series and soil pH,  soil nutrients  and plant community.   While evidence from 2000 suggests that AM fungi are not specialists on their host species,  studies as of 2002 have indicated that at least some fungi taxa are host specialists. 
There are varied uses of Tulsi plant. The plant is progressively finding its approach in the Ayurvedic treatment of diseases. Tulsi leaves are widely used because of their healing power. It is a tonic for the nervous system and so, helps an excellent deal in sharpening the memory. This aromatic plant supports the removal of phlegm and rubor matter from the cartilaginous tube. It also works wonders in preventing stomach disorders. The herb Tulsi is glorious to cure the metabolic process disorders. The simmering ready by mix honey, ginger and Tulsi leaves is sort of useful in combating respiratory disease, contagion and asthma attack.
Waterbac ® is a high strength microbial bio-fertiliser formulated to promote plant growth on irrigated crops. By solubilising P, nitrifying the soil, and ATP production it increases plant nutrition through improved mineral uptake. Additional PGPR attributes include the production of plant growth hormones such as auxins, gibberellins and cytokinins, and the presence of this bacillus bacterial complex in the soil has shown that there is mild suppression of many common root diseases . These benefits increase the ability for plants to experience healthier root growth.
