Dry Soils & Soil Testing

Iowa State University published a Bulletin this week cautioning about soil test results taken during extremely dry conditions, as has been the case in much of Iowa and parts of Illinois.  They advise waiting until moisture returns to sample, or to rely on previous years' soil tests taken in more normal conditions as a guideline, to ensure applied nutrient rates applied are not skewed when relying on test results taken in very dry conditions.
