Identification of Lime-Deficient Peat Soils1
- Iver J. Nygard2
Field and laboratory studies were made of 37 Minnesota peat bogs to fix the upper limit of lime content in the surface of lime-deficient bogs, and to determine criteria of lime-deficient peats3 other than the lime content. Field trials to determine whether the peats were lime-deficient, using common farm crops, were conducted on peats from 35 uncultivated bogs and two cultivated bogs. All lime-deficient peats and most of the lime-sufficient peats were extremely acid as indicated by pH measurements. A close correlation existed between the lime (calcium oxide) content and lime-deficiency. No native plant species were found to indicate lime-deficiency reliably.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
