Soil Sampling in Relation to Soil Heterogeneity1

Seven cultivated fields, pastures, and orchards—ranging from 2 to 35 acres in size—were sampled for one or more of the following: soil pH, soil moisture, and extractable K, Ca, Mg, and P. Cores 1 inch in diameter were obtained at various depths in a two- and three-stage sampling scheme. For fairly uniform fields, the efficiency of multistage sampling relative to simple random sampling was found to be high. The data show that a convenient multistage sampling method could be used in many physical and chemical sampling surveys of fairly uniform fields or fields that could be stratified into uniform sections.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
