As we get into harvest, what are the most interesting trial results on your farm?

A lot of us are running our own field trials on any number of products/practices, as combines roll what are some of the most surprising/interesting results? Bonus points for the best ROI.


For example this year I tried a fertigold humic/folvic dry product on spring wheat and saw a 2bu gain for a cost of ~$.50/ac.

I have often wondered about insecticide ROI in cotton. This year I planted a 105 acres of DPL 1646. From time of planting and all thru in season we sprayed 80 acres of it with all the necessary insecticide applications according to the threshold. My independent scout checks every week and is very thorough.

The remaining 25 acre control had no insecticides applied only PGRs.

The field average was...

WE have had a couple things show up this year. 1st- because of the early freeze up last fall and the late wet spring we had, we ended up no-tilling 100% of our soybeans. So far we have seen very little yield drag. This would include some very heavy clay loam soils. We will not be collecting any crop ins. 2nd we applied 30# of urea on half our corn acres at V4 growth stage. our yield monitor is sho...

Fall and spring tillage differences.


Fall - chisel plowed versus salford coulters. We only ran the salford coulter machine on all our bean stubble last year. Now that we have water standing in our crops and getting wetter. It is much easier to combine where the salford went compared to the chisel plow. Combing through the water and only sinking a few inches. Chisel plowed the cart has to w...

No till has proven to have more soil permeability (water infiltration capacity) than tilled ground by a factor of 10. Results in the URL so you can see for yourself. This is assuming that you don't have a subsoil compaction layer but no till lets us get in the field sooner than my neighbors w...

On our farm, in South-Central IL, the strongest correlation is between tillage speed and yield.


This translates to the ground being just a little too “moist”, which then causes compaction. So, the tillage speed actually is an indicator for drainage hot spots.


As logic would indicate, the normalized yield pattern is lower in these areas AND our fertility levels are higher. Our CEC levels are ...
