Southeast Research and Demonstration Farm
Every spring, farmers are faced with the decision of whether to replant soybeans because of stand losses due to hail storms, soil crusting, and damping off. A common practice when faced with this decision is to “thickenup” the stand by planting additional seed into the existing stand. Although this practice is usually discouraged by agronomists, there has been little research done to compare this practice with keeping the existing stand or destroying the stand and replanting.
