Effects of Good Management Following Soil Erosion1
- G. R. Free2
It has been reported previously that corn yields for a 2-year period on Bath flaggy silt loam, despite liberal fertilization, ranged from 17 to 88 bushels per acre depending upon past management and erosion during the preceding 11 years.
By the ninth year of continued good management, including fertilization and rotation and with a low rate of erosion, there were still significant residual effects of past treatments on productivity and on soil characteristics. Under a fertilizer treatment comparable to that followed during the initial 2-year period, corn yields ranged from 71 to 93 bushels per acre. This treatment provided nitrogen at the rate of 100 pounds per acre. Residual effects on yields were effectively masked when the rate was raised to 200 pounds per acre.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
