Dataset of organic phosphorus transformation in black paddy soils in northeast China

It aims to clarify the dynamic transformations of available phosphorus, primary mineral phosphorus, secondary mineral phosphorus, and occluded phosphorus; analyze the microbial-mediated phosphorus activation processes and metabolic strategies; reveal the response patterns of microbial community structure and phosphorus-solubilizing functional bacteria (such as Streptomyces and Cupriavidus); and ultimately elucidate the microbial mechanisms of phosphorus form transformation in black soil under long-term rice cultivation, providing theoretical basis and technical approaches for efficient phosphorus fertilizer management in black soil rice regions
