1、Phosphate bacterial solubilization: A key rhizosphere driving force

Although P fertilizers are agriculturally vital to secure crop growth and productivity, their use efficiency by crops significantly may be very low due to P fixation to soil cations.

2、Prospects for Using Phosphate

The problem of phosphorus deficiency in the soil has traditionally been solved by applying phosphate fertilizers. However, chemical phosphate fertilizers are considered ineffective compared to the organic fertilizers manure and compost.

3、Fermentation: A Process for Biofertilizer Production

Application of biofertilizers (N 2 fixing, phosphate solubilizing, phosphate mobilizing, and plant growth promoters), produced using microbial fermentation technology, is reported to enhance the crop productivity and soil fertility in a sustainable manner (Armada et al. 2014).

From Isolation of Phosphate Solubilizing Microbes to Their Formulation

The use of phosphate solubilizing microbes (PSMs) will efficiently increase fertilizers uptake by mobilizing insoluble phosphorus in the fertilizers and in soils to which they are applied (Suleman et al., 2018).

Phosphate Solubilizing Bio

To strengthen the application of phosphate solublizing bio-inoculants, there is a need to know and understand the methods for their isolation and characterization of phosphate-solubilizing microorganisms and the mechanisms they used to solublize phosphate to make it available for plant nutrition.

The Science Of Phosphates In Fertilizer Production

The use of phosphate fertilizers has raised environmental concerns over the years. When it rains, runoff can carry these chemicals into nearby streams, rivers, and lakes.

Why Is Phosphate Used In Fertilizer?

Phosphate fertilization has been shown to significantly increase crop yields. By providing plants with the necessary phosphate, farmers can maximize their harvests and improve agricultural productivity. Phosphate can help improve soil fertility by enhancing the availability of other nutrients.

Phosphate Solubilizing Microorganisms: Promising Approach as

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.

Phosphorus fertilizer: from commodity to speciality — from fertilizing

Plant specific P fertilization methods can improve P availability and use efficiency. Phosphatic fertilizers are indispensable for sustainable agriculture, but phosphorus (P) scarcity has drawn global attention with respect to research and policy discussions.

Exploring phosphorus fertilizers and fertilization strategies for

We argue that the improvement of the nutritional value of crops, especially cereals, through reduced phytic acid and increased zinc and iron contents should be among the most important drivers toward the development of innovative fertilizer products and fertilization technologies.

The effectiveness of phosphate fertilizers is closely tied to the fermentation process, as phosphorus in soil must undergo microbial action to be absorbed and utilized by plants. Below is a detailed explanation of why fermentation enhances phosphate fertilizer efficacy and the processes involved:

I. The Role of Microorganisms in Phosphate Fertilizer Effectiveness

1. Microbial Conversion of Phosphorus: Soil microbes, especially bacteria and fungi, decompose organic phosphorus compounds (e.g., unicellular algae) into inorganic phosphorus through mineralization, increasing soil soluble phosphorus content.
2. Microbial Enhancement of Phosphorus Absorption: Organic acids and chemicals secreted by plant roots promote the dissolution of poorly soluble phosphorus, facilitating plant uptake.
3. Microbial Phosphorus Immobilization: Some microbes help retain phosphorus within plants, reducing nutrient loss.
4. Microbial Competition for Phosphorus: In phosphorus-rich environments, excessive competition for phosphorus among microbes may limit its availability to others.

II. The Fermentation Process of Phosphate Fertilizers

1. Introduction of Microorganisms: Mixing phosphate fertilizers with organic-rich materials (e.g., compost, green manure) introduces beneficial microbes, including phosphate-solubilizing bacteria.
2. Decomposition of Organic Matter: Microbes break down organic matter to release energy, simultaneously liberating phosphorus into the soil.
3. Phosphorus Release: Microbial activity converts phosphorus from organic compounds into soluble inorganic forms.
4. Phosphorus Transformation: Released phosphorus is absorbed by plants or further utilized/transformed by microbes.
5. Phosphorus Accumulation: Under optimal conditions, fermented phosphate fertilizers significantly increase soil phosphorus content, boosting crop yields.

III. Why Fermentation Enhances Phosphate Fertilizer Effectiveness

1. Improved Phosphorus Bioavailability: Fermented fertilizers contain more soluble phosphorus, making it easier for plants to absorb.
2. Reduced Environmental Pollution: Unfermented phosphate fertilizers may contain hard-to-degrade substances; fermentation minimizes harmful residues.
3. Higher Fertilizer Efficiency: Microbes optimize phosphorus transfer from soil to plants, maximizing nutrient use.
4. Extended Fertilizer Longevity: Fermented phosphate fertilizers provide prolonged phosphorus release, reducing the need for frequent reapplication.

Fermentation enhances phosphate fertilizer effectiveness by increasing phosphorus bioavailability, reducing environmental risks, improving nutrient efficiency, and extending fertilizer lifespan. combining phosphate fertilizers with organic matter for fermentation is recommended for optimal results.
