Abstract

An investigation was undertaken to determine the reason for injurious effects of lime to grains grown on certain acid organic soils which occur in the Great Lakes region. Analyses were made of the soils (table I) and crops (table II) in order to determine if a harmful physical change occurred in the soils after liming or if lime was chemically injurious. The organic soils studied were black, powdery, acid and deficient in potash as shown by the soil analyses. Crop injury following use of lime to correct acidity in these soils is an unexpected response which occurs frequently enough to justify investigation.
