Nematodes are a growing issue in agriculture. Nematodes can cause major damage in several crops. Soybeans are one of the hardest hit crops with nematode pressure. Side effects of nematode in soybeans can result in yield reduction up to 50 percent and total plant loss depending on soil type. Without proper training and guidance, farmers can lose the ability to farm land that is hard hit by nematode. Most non-host crops such as peanuts or sorghum are not profitable for farmers in this area or equipment/transportation may be limited. We need sustainable practices such as cover crop rotation to help minimize the impact of nematode on our cash crops.
We are looking to cover crop rotation to help reduce the nematode number in the soil. Cover crops are a great use to maintain soil health, reduce erosion, and help with water infiltration. We are looking to use mustard greens as a cover crop that can be mowed down and tilled into the soil. Research that other universities have done have shown that mustard greens that are chopped and tilled create a natural nematode fumigant. To keep soybean production sustainable in a nematode infested field we will hopefully achieve better control with cover crop rotation that will allow the soybean to reach maturity. Once we have a better understanding of the data for cover crop options we hope to add more cover crop varieties into the mix offering farmers a variety of solutions across different land types. We believe that in order for a farmer to be prepared he must have all options at his disposal and have the research there to support those options. This research will be a critical tool to help farmers combat the growing concern that is the nematode pest in the South.
Objective One- Effective Time frames of Planting of Cover Crops to get the required Organic Matter
Objective Two- Cost of the field prep vs the cost of cover crop use.
Objective Three- Look at how much varieties impact nematode activity.
Objective Four- Use cover crops in rotation with a cash crop to increase yield while reducing the nematode population. This will be a Cover Crop Vs NO Cover Crop in a heavily nematode infested soil type.
1 acre block with Cover (Mustard) Spring Planted, then destroyed (Tillage) before cash crop planting.
1 acre block without cover standard practice
We are now trying to prove the concept so further research can be done at a later time.
