Phosphate-Solubilizing Bacteria Effect on Seedling Growth

by Anandagro care Dealer

Phosphorus (P) is a macronutrient required for the proper functioning of plants. Because P plays a vital role in every aspect of plant growth and development, deficiencies can reduce plant growth and development. Phosphate-solublizing bacteria (PSB) can turn insoluble phosphorus rhizosphere into plant-absorbable forms, thereby enhancing plant growth.

Anand Agro Care distinguished as the Phosphate solubilizing bacteria suppliers & manufacturers in Nashik. We adhere to severe quality measure, which ensures that our range of bio organic and herbal medicine is at par with our client's expectations. Our product Dr. Bacto’s PSB is the selective strains of Phosphate Solubilising valuable bacteria of Bacillus. Our phosphate solubilising bacteria fertilizers grow and secrete organic acids, which dissolve this unavailable phosphate into the soluble form and make it available to the plants.

Phosphorus is the world’s second largest nutritional supplement for crops after nitrogen. On average, soil contains 400–1000 mg kg−1 of total P, of which only 1.00–2.50% is available to plants for uptake. Phosphorus is found in mineral as well as organic forms of soil. An adequate supply of phosphorus is essential for establishing the primordia of plant reproductive parts during the early phases of plant growth. It plays a significant role in increasing the ramification and power of the heart, thereby imparting plant vitality and resistance to disease.

The improvement of plant growth and properties by PSB may be due to several possible mechanisms. By changing the soil composition, PSB alters the plasticity of seeds and roots. For example, plant growth-promoting rhizobacteria may improve the solubility of mineral nutrients by releasing organic acids and thereby increasing the vegetative biomass and N and P accumulation in plant tissues, simulating plant growth. This phenomenon, in turn, affects colonization and development of the bacteria.

The use of phosphate solublizing bacteria as inoculants simultaneously increases plant and crop yield uptake of P. The main mechanism for the solubilization of mineral phosphate is the production of organic acids, and acid phosphatases play an important role in soil mineralization of organic phosphorus. Several phosphatase encoding genes were cloned and characterized, and some of the genes involved in the solubilization of mineral phosphate were isolated. Genetic manipulation of phosphate-solublizing bacteria to improve their plant growth ability.
