Abstract
This mini-review deals with P-plant nutrition starting from the crude P-source, its further processing, most recent alternative P-sources, and biotechnological solutions of existing problems. Special attention is given to microbial P solubilization in fermentation systems as an alternative of chemical P-fertilizer production. Another emphasis of the mini-review is on the biofertilizer production and formulation.
Highlights
P is quite abundant in many soils, it is added to soil-plant systems in the form of phosphate fertilizers
Phosphorus (P) is one of the major nutrients limiting plant growth
During the last 10-15 years, scientists working in this field focused their studies in two main directions: A) Changing the traditional rock phosphate chemical dissolution scheme and finding alternative sources of P; B) Preparation of formulated biofertilizers with P-solubilizing activity
Summary
P is quite abundant in many soils, it is added to soil-plant systems in the form of phosphate fertilizers. Traditional P fertilizer production is based on chemical processing of insoluble mineral high-grade rock phosphate-what is calcium phosphate combined with quartz, calcite, dolomite, clay, iron oxide, carbonates, and alkali compounds. During the last 10-15 years, scientists working in this field focused their studies in two main directions: A) Changing the traditional rock phosphate chemical dissolution scheme and finding alternative sources of P; B) Preparation of formulated biofertilizers with P-solubilizing activity.
