Reducing Nematicide Use in Soybean by Understanding Soil Textural Zones

Changing farming practices in the Mid-South USA have exposed soybeans to damage from southern root-knot. Damage from these nematodes is associated with soil texture (higher or lower sand content). A three-state research project is determining the relationship of soil texture to yield loss from these nematodes. Our results will help farmers use soil textural zones to limit nematicide use to only those parts of fields where yield loss is likely.
