Assess Effect of Phosphorus Biologic Fertilizer to Improve Crop Production under Warm and Dry Climate Condition

Chemical fertilizers have several negative impacts on environment and sustainable agriculture. Therefore, bio fertilizers are recommended in these conditions and growth prompting bacteria uses as a replacement of chemical fertilizers. Symbiotic bacteria have positive role in the production of bio-fertilizers and hormones which play a significant role in regulating plant growth while mixing them with chemical fertilizers as a supplement the level and depth of the roots. This combination also increases the rate of water and nutrient absorbance which raise the rate of growth and photosynthesis. The inoculation of soil or crop with phosphate solubilizing/mineralizing microorganisms is therefore a promising strategy for the improvement of plant absorption of phosphorus and thereby reducing the use of chemical fertilizers that have a negative impact on the environment. This review has shown that phosphate-solubilizing microorganisms (PSM) have tremendous potential as Bio-fertilizers. Mobilizing soil inorganic phosphate and increasing its bioavailability for plant use by harnessing soil PSM promotes sustainable agriculture, improves the fertility of the soil, and hence increases crop productivity. The use of PSM as microbial inoculants is a new horizon for better plant productivity. PSM technology can contribute to low-input farming systems and a cleaner environment. However, there is need to develop PSB technologies specific to various regions and this should be communicated to farmers in a relatively short time. By using phosphate solubilizing microorganisms in crop root zone and soil, the capability of phosphate availability through insoluble phosphate resources will increase and the efficiency of phosphate fertilizers such as superphosphate will improve. Biological phosphorus fertilizers are good substitutes for phosphate chemical fertilizers. They contain two phosphate solubilizing bacteria which dissolve the soil phosphorus using two mechanisms of organic acid and phosphatase acid secretion.
