Experiment designed to show the relationship between soil and changes in the vegetational cover.

During the summer of 1938 a long time study was inaugurated designed to show the relationship between the soil and the vegetational cover in the region of Douglas and Burt Lakes in the western part of Cheboygan County, Michigan. During the summer of 1939 this project was continued with the collection of soil samples from each soil horizon in the various plots, and these samples are to be analyzed during the coming year for the quantity of organic matter present, the minerals present, the wilting point, and for their physical composition including the coloidal content of the soil.http://deepblue.lib.umich.edu/bitstream/2027.42/51698/1/124.pd
