Potassium Solubilizing Bacteria (KSB)

  • Chapter
  • First Online:

Abstract

Potassium (K) is reflected as a fundamental supplement and a noteworthy constituent inside every single living cell, which is required in vast sums by plants, animals, and people. In environment, soils normally contain K in bigger sums than some other supplements.As rocks gradually weathered, K is discharged, yet change of K from the basic portion to some other frame is as often as possible to ease back to give them a lot of this basic supplement required by crops. Utilization of chemical fertilizers has an extensive negative effect on ecological supportability. Potassium solubilizing bacteria (KSB) solubilize K-bearing minerals and change over the insoluble K to dissolvable types of K that plants can get to. Countless soil microscopic organisms, for example, Acidithiobacillus ferrooxidans, Paenibacillus spp., Bacillus mucilaginosus, B. edaphicus, and B. circulans, have ability to solubilize K minerals like biotite, muscovite, feldspar, mica, iolite, and orthoclase. KSB are normally present in every one of the soil, in spite of the fact that their number, assorted variety, and capacity for K solubilization differ which rely on the soil and climatic conditions. Despite that, KSB are the most essential microscopic organisms for solubilizing K minerals which demonstrate viable association amongst soil and plant frameworks. These microbes can be utilized productively as a wellspring of K-fertilizer for managing crop generation and keeping up soil K. Subsequently, generation and administration of organic manures containing KSB can scatter K inadequacy particularly in paddy field or zones where plants are normal for K and are likewise an approach to accomplish the objectives of the practical farming. This article shows a diagram of flow patterns and difficulties on the KSB, components, and their part in plant development advancement and in the end gives a few viewpoints for study on K in agriculture.
