PSB and KMB Biofertilizers for Soil Fertility in Telangana

Phosphate Solubilizing Bacteria (PSB) and Potassium Mobilizing Bacteria (KMB) are beneficial soil microorganisms used in biological nutrient management programmes. Telangana farmers cultivating paddy, cotton, maize, turmeric, chilli, red gram, soybean, groundnut, sugarcane and vegetables can incorporate suitable PSB and KMB formulations into integrated crop nutrition practices. PSB help solubilize certain insoluble phosphorus compounds, while KMB can contribute to the mobilization of potassium from suitable soil minerals under favourable conditions. Their performance depends on microbial strain, soil pH, organic matter, moisture, mineral composition, nutrient reserves, crop requirements and appropriate application methods.

Phosphate Solubilizing Bacteria for Phosphorus Availability in Telangana Crops

Phosphorus plays an important role in root development, energy transfer, early crop establishment and several essential plant metabolic processes. In agricultural soils, a portion of phosphorus may become associated with calcium, iron or aluminium compounds that limit its immediate availability to plant roots. Suitable PSB strains produce organic acids and other metabolites that can help solubilize selected phosphorus compounds in the rhizosphere. Farmers should combine PSB applications with soil testing, balanced fertilization, suitable irrigation and organic matter management because microbial inoculation does not create phosphorus or replace all crop fertilizer requirements.

Potassium Mobilizing Bacteria for Cotton, Maize, Turmeric and Chilli

Potassium supports enzyme activation, plant water regulation, carbohydrate transport and several physiological functions associated with crop development. Certain soil minerals contain potassium that becomes available gradually, and suitable KMB strains may contribute to the release of a portion of this mineral-bound nutrient. Telangana farmers cultivating cotton, maize, turmeric, chilli, paddy, soybean, groundnut and vegetables can consider KMB as part of integrated potassium management programmes. However, KMB cannot compensate for severely depleted potassium reserves, and farmers should maintain adequate potassium nutrition according to soil testing and crop-specific recommendations.

PSB and KMB Application Through Seed Treatment, Soil Drenching and Drip Irrigation

PSB and KMB biofertilizers are available in liquid, talc-based powder and other suitable formulations for different agricultural applications. Depending on the product label, farmers may apply these microorganisms through seed treatment, seedling root dipping, soil incorporation, root-zone drenching, orchard basin application and compatible drip irrigation systems. For applicable Bactostore India products, general field recommendations include 1–2 kg of powder biofertilizer or 2 litres of liquid biofertilizer per acre per application, subject to crop-specific label instructions and formulation suitability. Talc-based powders require thorough mixing, continuous agitation and suitable filtration when approved for drip application, while clean irrigation lines and adequate flushing help reduce sediment accumulation and emitter-blockage risks.
