Accretion and dilution of nutrients in young corn, as affected by yield response to nitrogen, phosphorus and potassium

, : Accretion and dilution of nutrients in young corn, as affected by yield response to nitrogen, phosphorus and potassium. Soil Science Society of America Proceedings 38(3): 455-460

In pot trials, hybrid maize on infertile soil was given 0, 100, 500 or 1000 mg N, 0, 50, 250 or 500 mg P, or 0, 100, 500 or 1000 mg K/pot. Other nutrients were applied in each series at uniform levels. Near-linear increases in uptake of N, P or K with amount applied occurred during 25, 41 and 53 days of growth, respectively.
