Southeast Research and Demonstration Farm
Soil moisture levels were adequate to surplus going into the growing season, due in part to heavy precipitation during the fall and winter months of 2000/2001. March precipitation was below average, but little, if any, fieldwork was done during this time because the soils stayed cool and wet. Small-grain planting and anhydrous ammonia applications were not made until mid–April, but corn and soybean planting were not far behind. Planting began on April 18 and continued through April 20, when heavy rain prevented fieldwork until April 30. Planting then continued through most of May despite more heavy rains. Little fieldwork was done between May 3 and June 10, after which most of the remaining crops were planted.
