I Just got my Whitetail Institution soil samples back from my 5 plots from the lab in Memphis. All of my plots where created out of the woods. Smallest is 0.12 to the largest being 0.53. This is the 3rd year I done soil samples. First time was Feb 2020, I only had 2 plots. Both came back with pH of low 6's. Last August, I added the others and expanded the first 2. I did the 3 additional right after creating them. The pH for these were around 6. I put down 1,480 lbs of lime by push spreader on all 5 plots per recommendations from the samples. How accurate is these samples? Reason I ask, all my plots came back this year at 6.8-7.1 range. Most jumped 0.6-1.0 on pH. Recommendation was 0 lime for all 5 plots. Fertilizer came in like 30-60lbs per acre on a couple of plots. An area I'm concerned about, the CEC and Organic Matter %. 3 of my plots the CEC was below 10 and 1 had the organic matter drop from 9.3% on the other sample to 5.8%. What can I do to improve the CEC and Organic Matter in those plots that are low?
