  		Fig. 1. Soil profile distribution of pH from long-term application of broiler litter (BL) and ammonium nitrate (AN) sources of total N for cotton and corn at sites in the Coastal Plain (CP) and Tennessee Valley (TV) of Alabama. Error bars are the SE at each depth for the means of each treatment.

  		Fig. 7. Mehlich-1 extractable P and K in surface 10 cm for selected treatments at the Coastal Plain site from 1993 to 2000. Error bars are the standard error of the mean for that observation. Treatments are designated as ammonium nitrate (AN) or broiler litter (BL) followed by the annual total N rate in kg ha–1.
