Agricultural Review


In the eastern part of the state, potassium and sulfur fertilization require special attention this season.

Abundant rain during the fall/winter of 2009–10 is likely to have depleted soil reserves of potassium and sulfur. This situation is most probable in the coastal plain region east of Raleigh on sandy soils with low organic matter and low cation exchange capacity (CEC ≤ 3). Growers on such soils would be well advised to put out 100 pounds per acre of potash (K2O) and 20 to 25 pounds per acre of sulfur for crops like corn, cotton and soybeans. Soil test report recommendations based on samples collected before the rainy period may no longer be accurate.
