All but two of the plots have a significant change in pH over the various treatments in the first sampling for this season. Most plots also showed a increase in pH over the winter. Plant population and residue counts have also been completed on all plots. Each of the four fields have been sampled to create an Order 1 soil survey. We used depth of A horizon and depth to glacial till as our parameters for mapping because the those were the differences between the current map units in all fields.
Work is currently under way to create the survey.
Rock Co. All four fields have been planted and cropping information has been requested from the producers. Activities planned between now and the next reporting period. Soil samples will be taken in each plot on six week intervals and analyzed for pH to track the lime neutralizing over time. Plant samples will be taken in each plot to analyze for plant nutrient content. Plant samples will consist of corn earleaf at silking or soybean trifoliate at flowering.
