Soil heterogeneity and soil testing.
Netherlands Journal of Agricultural Science, 1955 The error of analysis is generally small. The standard deviation influenced by analysis and sampling averages 10% in P, K and Mg determinations. The error in pH value is approximately 0.1 per unit. There is little difference between grassland and arable land or between various types of soil in this respect; the size of the field has, on the average, no
