2008-07-11 Soil Preparation Jim Stoneburner used the JD 5425 and JD 970 cultimulcher to pack the soil in the switchgrass fertility/harvest timing study. The area was uneven after Jim went over the area so I went over the area three times with the JD 6420 tractor and JD 960 field cultivator. I went over the area in different directions, I went deep with the field cultivator to move the soil around to make sure to level the soil in the study area. After the field cultivation Jim when over the area again with the JD 5425 tractor and JD 970 cultimulcher.

2001-05-04 Soil Preparation In the Biodiversity Study all replications of all spring tillage treatments were soil finished and cultimultched. Soil finished and cultimultched all replications of all treatments of the Nitrogen Rate Study.

2001-10-02 Planting Planted grass in the Biodiversity study alleyways. After planting the grass I used the JD cultimutcher (with the teeth just touching the soil) on the alleyways. I am sure I used the JD 5400 tractor and JD 450 10' drill to seed the grass.

2014-05-31 Soil Preparation Cultmulched twice in one day. Because of clumpy soil conditions we used the cultimulcher in main site T4 plots, all replications (4, 3, 2, 1, 5, and 6) with a two passes (in the same day) with the JD7420b tractor and the JD970 cultimulcher. The first pass was N-S over the plots and the second pass was on a slight angle to the NE-SW with 1 headland pass going E-W on both north and south side of each plot. All plots were cultimulched with the teeth in the ground about 2-3 inches. Speed was ~ 4.5 - 6 mph depending on soil conditions. Reason for cultimulching the second time on the same day was to break up more soil clumps.

2015-05-19 Soil Preparation Because of clumpy soil conditions we used the cultimulcher in the LTER main site T1 plots, all replications (5, 1, 3, 2, 4, and 6).
