Progress Report 4d Progress report. This report serves to document research conducted under a specific cooperative agreement between ARS and N-Viro International Corporation. Additional details can be found in the report for the parent project 1275- 22000-203-00D: Microbes, natural products, and amendments for management of plant-parasitic nematodes. Because new management tools for control of plant-parasitic nematodes are urgently needed, this cooperative agreement provides N-Viro-mediated funding to several universities to conduct field and other experiments examining nematode control with a biomineral soil amendment. The cooperating institutions are Iowa State University, Michigan State University, North Carolina State University, Ohio State University, and the University of Florida. In this fifth year of the cooperative agreement, the results indicated that rates in excess of 20 t/a of the amendment will be required for nematode control, and that this amendment will
have to be applied in a site-specific manner to achieve control of root-knot and cyst nematodes. This research will help growers determine if they can successfully utilize the soil amendment to control nematodes and enhance yields in specific crops.

The cooperating institutions are Iowa State University, Michigan State University, North Carolina State University, Ohio State University, and the University of Florida. In this fourth year of the cooperative agreement, experiments indicated that the soil amendment can increase the yield of tomato plants and temporarily reduce root-knot nematode populations and
nematode-induced root damage. In addition, use of the amendment resulted in cotton yield increases, as well as an initial reduction in root-knot nematode population levels. This research will help growers determine if they can successfully utilize the soil amendment to control nematodes and enhance yields in specific crops.

4. What were the most significant accomplishments this past year? D. Progress Report This report serves to document research conducted under a specific cooperative agreement between ARS and N-Viro International Corporation. Additional details can be found in the report for the parent CRIS 1275- 22000-203-00D: "Microbes, natural products, and amendments for management of plant-parasitic nematodes." Because new management tools for control of plant-parasitic nematodes are urgently needed, this cooperative agreement provides N-Viro-mediated funding to several universities to conduct field and other experiments examining nematode control with a biomineral soil amendment. The cooperating institutions are Iowa State University, Michigan State University, North Carolina State University, Ohio State University, and the University of Florida. In this third year of the cooperative agreement, experiments have indicated that the soil amendment can provide control of root-knot
nematodes and increase the yield of tomato plants in Florida, reduce damage to tomato roots caused by populations of root-knot nematodes from six different states, and reduce soybean cyst nematode numbers under some but not all conditions. This research will help growers determine if they could successfully utilize the soil amendment to control nematodes and enhance yields in specific crops.
