The article considers raw material biological indexes changes caused by application of different solubility forms and phosphate doses. Investigeted was tea plants of long-term fertilized red soils on which physiologically acid (simple and double suterphosphate ) and neutral(phosphate slag and fluorine-free phosphate) phosphorus fertilizers. The young tea-plucks were taken to determine tannin, exstractive substances and general phosphorus. With an increase in age of tea plants the solubility of different phosphates begin to smooth based on experimental data. Thus physiologically acid and neutral phosphorus slightly differ by their effect on some biochemical indexes of tea leaf.
