Summary

The magnitude of response to fertilizer-N and fertilizer-P decreased with increasing amounts of total soil-N and available soil-P, respectively. Attempts have been made to group the soils into N- and P-fertility classes based on the magnitude of response to applied fertilizers on soils of different fertility with respect to these two nutrient elements.
