Technical Abstract: A field experiment was conducted at the Arkansas Valley Research Center in 2007 to test the residual effects of two years (2005 and 2006) of manure application (10, 20, and 30 tons/acre) and N fertilizer (60, 120, and 180 lb N/acre) on corn yield, N and P uptake, and soil N03-N and P concentrations under subsurface drip irrigation (SDI) and furrow irrigation (FrI). There were no significant differences in corn yield between SDI and FrI in 2005, 2006, and 2007, even though, on average, 43% more water was applied with FrI than with SDI. The highest corn yields were obtained with 180 lb N/acre in 2005 and with as little as 60 lb N/acre or 10 tons of manure/acre in 2006. With no N fertilizer or manure applied in 2007, the residual manure and high N rate treatments produced an average of 224 bu/acre of corn. At the end of 2007, there was enough residual soil N left in the high manure treatment to produce top corn yields for two years. Applying manure in excess of crop nutrient requirements can lead to N and P buildup in the soil and associated water pollution hazards, as demonstrated in this study
