'Plots were sampled on January 2, 2008 by Diana Wall and Byron Adams, with direction from Breana Simmons. Solar chambers from the OTC plots were used as a guide for sampling. To ensure sampling under the treated area, the cone was centered in the plot and the sample was taken from the exact middle. Future samples should be taken in a "clockwise" formation. A stake was driven in at the 12:00 position (south) in all plots by Ed Ayres and Byron Adams, so that in the future, chambers can be set up against it as a guide for both sampling and treating. In blocks 5 -8 stakes were put in at at the 6:00 position due to plot logistics (you cannot walk BETWEEN plots 5 and 6 or 7 and 8 - paths are on the outside - see map).
Plots were treated by Byron Adams and Breana Simmons. Diana Wall and Ed Ayres filled containers. To reduce the number of pour jugs, two C, N and P jugs were used, for a total of 6 jugs. DI was applied first, then C, P, CP (from the P jug), CN (from the C jug) and N. This is not as confusing as it sounds. Chambers were placed again, over the center, against the nail, as a guide for pouring. Any solution containing C became hard to pour and jugs were shaken rigorously over plots.
Fresh soil was weighed by Ed Ayres into soil cans and placed in a 105C oven for 24 hours. Diana Wall and Breana Simmons were on screens. Byron "Skua Boy" Adams centrifuged and played paper towel wad basketball. Dry soil was weighed by ??. Nematodes were counted by ??.
