Non Technical Summary
Iron deficiency chlorosis (IDC) is a destructive disorder of soybeans grown on high water table soils of the North Central USA. IDC is such a bad problem, because the growing point (youngest leaves) can be injured or killed early in the growing season, leading to very low yield. The purpose of this project is to identify new soil, seed, and foliar spray treatments that can reduce the severity of IDC in soybeans. These treatments include growth regulators and biostimulants that work alongside of existing technologies (application of iron fertilizer with the seed), to reduce the severity of IDC and increase soybean yield on these difficult-to-farm fields.

Goals / Objectives
1. To screen new soil, seed, and foliar chemical treatments, for the reduction of iron deficiency chlorosis (IDC) in soybeans under greenhouse conditions.2. Soil, seed and foliar chemical treatments for control of iron chlorosis soybean, identified under Objective 1, will be evaluated under field conditions.
Project Methods
Details of the methods are outlined in the project proposal. To summarize for Objective 1, compounds that may work to reduce IDC in soybean plants are screened under greenhouse conditions, using a high-throughput screening protocol, using single-plant conical pots ("conetainers") that are grown in racks. A screening "run" can evaluate up to 14 combinations of compounds and rates of compounds, and is suitable for evaluating soil, seed, and foliar treatments. To summarize for Objective 2, compounds shown to reduce IDC in the greenhouse are evaluated in the field, using traditional randomized complete block field design. Already, new seed treatments and foliar sprays have been identified for field research.
