Popis:	(…) A 2-yr study was conducted in a rhizotron at Ames IA, to determine whether drying of the fertilized, surface soil layer reduces plant growth and utilization of P and K fertilizers when subirrigation replenishes water below the fertilizer surface layer. Low, medium, and high fertility levels were established on soil obtained from the upper 0.15 m of a Sparta loamy, fine sand (sandy, mixed, mesic Entic Hapludoll). (…)
