No residue moved or furrows made from residue managers. First corn year following soybeans(22), wheat (21), soybeans(20). Dwayne says this is the field you show the banker!! Nightcrawlers are gathering surface residues over their burrow (called midens). In July, when corn is tasseling, the soil suface could be bare because of biological activity. Dont fear, the soil is protected by corn biomass above!! Soil health is great!!

Hi Anthony, I took my trash whippers off in 2014. I put them back on three different years, but they never made it more than one or two fields, and then came off. One year I did a farmer test, trash whippers down and no trash moved. The corn emerged sooner and more uniform where I used the trash whippers, but in the fall the rounds were nearly equal in weight with the grain cart. Today I plant though anything and everything without them. This morning walking in my fields I noticed very even emergence, but I waited for warmer temps to plant. Jim Williams

A couple observations. Notice how the residue is evenly distributed in the picture! This is a must in my opinion. You are following a low c/n crop so residue is broke down faster. I planted in wheat stubble leaving trash wippers up on half planter and slight trash movement on the other half. Areas where residue was drove over emergence is very erratic in the area with no trash movement. They are still coming but where minimal residue was moved plants have been up 3 days. Where no residue was moved some plants are up and others are still 2-3 days away from emergency. I feel the use of trash whippers is a field by field evaluation. Thanks for sharing Anthony.
