COLLECTION OF SOIL SAMPLES

At a minimum, one soil sample shall represent an area of no more than 40 acres. Additional soil samples may be required if there are areas differing greatly in previous fertilization, liming, cropping history, land management, or soil texture. The soil must be sampled to a depth of six to nine inches from at least 15 to 20 random locations in the sampling area. The samples must be composited, thoroughly mixed, and subsampled for analysis. Approximately one pint of soil is necessary for analysis.
