1、MINERALIZATION OF PHOSPHOROUS BY PHOSPHATE SOLUBILIZING MICROBES

To meet the demand of plants and reduce the adverse effect of chemical fertilizers, use of PSM (Phosphate Solubilizing Microorganisms) is an effective and eco friendly approach.

2、Fertilization type affects the genetic potential for phosphorus

Conventional and mineral phosphorus (P) fertilizers face depletion risks, but organo-mineral fertilization strategies can reduce P demand in crops.

3、Sources and Solubilization of Phosphatic Fertilizers

Mineralization is governed by many factors such as moisture content, tillage, management, temperature, pH, and redox potential (Karamesouti and Gasparatos 2017).

Soil phosphorus transformation and plant uptake driven by phosphate

Phosphate-solubilizing microorganisms (PSMs) significantly enhance the ability of plants to absorb and utilize P, which is important for improving plant nutrient turnover and yield.

Review on Mechanisms of Phosphate Solubilization in Rock Phosphate

Various methods of solubilizing P from Rock Phosphate (RP) are discussed in detail in this review article, which includes physical treatments, chemical treatments, and application of microorganisms as well.

Prospects for Using Phosphate

Aside from chemical fertilization, microbial phosphate solubilization and mineralization seem to be the only possible way to increase the amount of phosphorus accessible for plants.

Mineralization of soluble P fertilizers and insoluble rock

Phosphorus mineralization was measured by analyzing extractable P from the amended soil incubated under controlled conditions at 25 °C for periods of 0, 5, 15, 25, 35 and 60 days. A complementary greenhouse experiment was conducted in pots with chilli (Capsicum annuum L.) as a test crop.

Phosphate in Physiological and Pathological Mineralization: Important

Phosphate is an important element in biological processes, particularly in the formation and metabolism of mineralized tissues such as bones and teeth. The imbalance of phosphate is also closely related with pathological mineralization.

Our objective was to examine the P mineralization potential of two soluble P fertilizers (SPF), i.e., single superphosphate (SSP) and di-ammonium phosphate (DAP), and of insoluble rock...

Phosphorus mineralization can be driven by microbial need for carbon

Despite the importance of phosphorus (P) mineralization to maintain soil fertility, little is known about the mechanisms that regulate microbial P mineralization. We tested the hypothesis that microbial P mineralization can be driven by microbial need for carbon (C).

Phosphate fertilizer, also known as phosphoric fertilizer or phosphate fertilizer, is an essential agricultural input primarily used to supply plants with phosphorus, an element crucial for their growth. Phosphate fertilizers mainly exist in two forms: solid and liquid. Solid phosphate fertilizers include materials such as phosphate rock powder, while liquid forms are typically water-soluble phosphate salt solutions.

Mineralization refers to the long-term geological process through which minerals gradually transform into soluble compounds in nature. During this process, certain elements within the minerals are released, forming soluble ions that can be absorbed and utilized by plants. the mineralization of phosphate fertilizers is a prerequisite for their effective nutrient uptake by plants.

Firstly, phosphorus in its elemental form within phosphate fertilizers is not directly biologically active and cannot be readily absorbed by plants. when phosphate fertilizers come into contact with water, their phosphate ions undergo hydrolysis, producing hydrogen ions and phosphoric acid. These then react with calcium ions in the soil to form soluble calcium phosphate, a process known as mineralization. The phosphorus in mineralized phosphate fertilizers becomes directly accessible for plant absorption, thereby enhancing fertilizer efficiency.

Secondly, the mineralization process contributes to improving the stability of phosphate fertilizers. Since phosphorus tends to volatilize at high temperatures and crystallize at low temperatures, mineralization reduces volatility, minimizing losses during storage and application. Additionally, this process increases the solubility of phosphate fertilizers, facilitating easier absorption by plants.

mineralization aids in soil environment improvement. Through mineralization, phosphorus transitions from a solid to a liquid state, increasing the soil's soluble phosphorus content and enriching its fertility. This process also stimulates the activity of soil microorganisms, accelerating the decomposition and transformation of organic matter, further enhancing soil conditions.

the mineralization of phosphate fertilizers involves complex physical and chemical transformations, affecting their form, reactivity, and soil interactions. This process not only boosts the efficacy and stability of phosphate fertilizers but also improves soil health and plant growth quality. Consequently, it is imperative to deepen our understanding and application of phosphate fertilizer mineralization to fully leverage its role in agricultural production.
