Psuedomonas species helps in solubilizing zinc and makes it readily available in the soil. These bacteria improve the plant growth and development by colonizing the rhizosphere and by solubilizing complex zinc compounds into simpler ones thus making zinc available to the plants. One of the mechanisms by which these microbes provide zinc to the soil is by acidification. These microbes produce organic acids in the soil which leave zinc ions in the soil for plant uptake and decrease the pH of the nearby soil. It increases the crop yield and improves the soil health by enhancing the nutrient content.
