Proper soil fertility management ensures sufficient nutrients for maximum cotton production.

At the same time, excessive nutrient application wastes money, wastes natural resources, and can negatively impact yields and environmental quality.

The 2014 grain sorghum OVT tests contained 52 hybrids; 41 hybrids were planted as a full season crop and 21 as double crop.
