摘要:
Total N, P, K, Ca, and Mg concentrations were determined in corn (Zea maysL.) and in southern pine seedlings (Pinussp) grown in N, P, and K response experiments in greenhouse pots. Analyses of variance were made for dry matter yields, for nutrient concentrations, and for nutrient uptake determined for individual pots and calculated as percent nutrient of composite samples times individual pot dry matter.
