However, even though we are dry, we still have IDC symptoms.

 

IDC can be caused by a combination of factors:

a)      Carbonates

b)      pH higher than 7.0

c)      Soluble salts

d)      Soil moisture

e)      Herbicide application

f)       Environmental stress

 

Foliar products do not help, so here are some things to consider for the future:

1)      Plant more tolerant varieties

2)      Test the soil for Calcium Carbonate (CCE)

3)      Use a planting time application of Iron Chelate

4)      Plant soybeans closer together, by increasing population or using wider rows

5)      Seed a cover crop with the soybeans

6)      Map the IDC areas for the future
