Soybean replant decisions should be based on accurate stand count and interacting factors, including yield potential of the existing stand, planting date, maturity group, and the true cost of replanting. Unfortunately, producers tend to make replant decisions based on quick visual estimations that often underestimate the existing plant population. Seedlings are usually in an early vegetative growth stage with only a few leaves when early stand counts are made. Narrow row widths exaggerate the impression of a low stand level because there are larger within-row spaces between plants.
CBOT is a Designated Contract Market that offers products subject to CBOT rules and regulations.

Photographs and movies of insects and the damage they cause. From Iowa State University Entomology.
Staying on top of all the latest ag technology, field data and research can be overwhelming. That’s why the Soybean Research & Information Initiative, formerly the Plant Health Initiative, continually provides you with access to expert information and news about soybean pests, diseases, and agronomics. The aim of this check off-funded website is to communicate the on-going progress and current understanding coming from your active and wide-ranging U.S. soybean research programs.
The Plant and Insect Diagnostic Clinic provides diagnosis of plant problems (plant diseases, insect damage, and assessment of herbicide damage) and the identification of insects and weeds from the field, garden, and home. The PIDC is a joint effort between Iowa State University Extension Plant Pathology, Entomology, Horticulture, and Agronomy.
The Iowa State University Soil and Plant Analysis Laboratory (SPAL) is part of the Department of Agronomy in the College of Agriculture at Iowa State University.
