Influence of soil pH and microbes on mineral solubility and plant nutrition: A Review

Soil pH is one of the essential vital features that increases or decreases the nutrient availability in soil. The lower pH lessens the secondary macronutrient availability while higher pH limits the available micronutrient in soil. Furthermore, the pesticides efficiency, use of organic and inorganic fertilizers sources to soil also required proper pH for maximum utilization by plants. Therefore, soil pH is termed as "principal soil indicator" that affect the biogeochemical cycles and has broader effects on the soil microbial community. Mineral approaches used to alter the soil pH had demonstrated drawbacks that it is too difficult to change. That's why alteration in rhizospheric pH can be a practical approach. Hence, a microbial-breeding technique such as genome replication of microbes may be a suitable approach to alter rhizospheric pH. It might be possible that microbes genetic product releases too much acidic or basic compounds that increase or decrease the pH of rhizosphere. Greater exploitation of microbes in this respect would be essential to pursue, as they have the ability to resolve several stresses in a more sustainable manner. In order to breed the microbes selectively for optimal nutritional interactions with plants, the genetic components of different traits must first be practiced.
