- CHALLENGES FOR MAKING INTENSIVE SOIL SAMPLING AND VRT PAY. ONGOING
Comparison of Soil Sampling Methods Results of sampling many corn and soybean fields using various sampling methods show that the spatial variability of P, K and other nutrients in soils is very complex.
- Soil Facts
For general soil sampling information, see Soil Facts, Careful Soil Sampling: The soil tests are based on years of field calibration trials with crops grown on relatively small, uniform experimental plots.

Results Scale of Sampling and Soil Test Variability Table 1 summarizes ST variability on 4 scales: (1) a 90 acre field sampled in 2.

However, it provides no information about the Even though yields may vary over distances of tens or hundreds of feet and even though application of fertilizer might be varied accordingly, unless the soil sampling grid is sufficiently detailed, there will.
