Abstract

This article presents data on the influence of different types and application rates of phosphorus-containing fertilizers on the phosphate regime of meadow-serozem soils. The application of phosphorus-containing fertilizers in cauliflower cultivation on meadow-serozem soils led to a significant improvement in plant phosphorus nutrition by increasing the content of the most bioavailable fractions - CaI–P and Aℓ–P. It was established that the content of mineral phosphates increased by 1.2–1.8 times compared to the initial levels, while the amount of organic phosphorus remained practically unchanged.
