The productivity of many ecosystems is determined by the chemical stability of phosphate, its relative immobility in soil, and its low concentration in the soil solution (approximately 1 xM). Phosphorus uptake by plant roots occurs mainly as phosphate ions (H2P0 and HPO ) from the soil solution, which depends on the solubilization of mineral phosphates and the degradation or mineralization of organic phosphorus. During phosphate uptake, a phosphorus-depleted area is formed close to the root, since phosphate uptake is faster than its diffusion in soil (Bhat and Nye, 1973). Having...

A further limitation of the CENTURY phosphorus model is the lack of an explicit representation of the impact of soil enzymes on the mineralization of organic phosphorus compounds. The results presented in this book indicate that there is limited data with which to quantify the relative importance of enzymatic hydrolysis of organic phosphorus [biochemical mineralization) vs. organic phosphorus mineralization associated with the decomposition of organic compounds [biological mineralization). It is very difficult to develop models that include enzymatic mineralization of organic phosphorus without data to quantify the relative importance of this process.
