- 1Affect on soil sampling methods: Previous fertilizer methodMethod of application for fertilizer and the method of mixing it into the soil will impact uniformity of nutrients spatially and with soil depth. Sampling areas with banded fertilizer.
- 2Affect on soil sampling methods: Tillage systemTillage will impact distribution of nutrients over a field and over depth. This will impact sampling density.
- 3Affect on soil sampling methods: Nutrient StratificationNo-till systems have greater stratification than conventional tillage. Consistent sampling tot he recommended depth is critical in no-till. for pH: two samples are needed, one at 0-1 in. and another from 1-6 in.
- 4Affect on soil sampling methods: within field soil and crop variabilityFor uniform fields: one sample should not represent more than 10 acres. If they are known areas of the field with different management practices, more frequent subsamples should be taken (if the area is too small to be managed as a separate field)
- 5Variability in soil test results: time of sampling
