Sentence examples for phosphorus requirements from inspiring English sources

Application of treated sewage sludge as amendment to land could account for the larger part of the nitrogen and phosphorus requirements for many crops.

Optimal culture conditions were investigated for the continuous culture of Isochrysis affinis galbana (T-Iso) by assessing the effects of irradiance, temperature, pH and nitrogen and phosphorus requirements.

The phosphorus requirements for dairy heifers (0.20 0.35%) and endogenous concentrations (0.20 35%) of P in feeds fed to dairy heifers are similar, suggesting that the need for supplemental P in dairy heifer diets may be minimal.
