Technical Bulletin No. 0404: Field Study Program Elements To Assess The Sensitivity Of Soils To Acidic Deposition Induced Alterations In Forest Productivity

The attached technical bulletin was designed to assist company foresters in selecting the soil parameters to be measured in field studies designed to detect changes in soil properties that may have been altered by acidic deposition. After discussing the elements of field sampling, soil sample preparation and initial soil characterization information is covered in detail. The measurements to be made were then divided into the minimum judged to be adequate, and a complementary group of others which were desirable in a program designed to determine changes in soil composition attributable to acidic deposition.
