Strip-Tilling Helps Boost Potato Yields To Record Levels
Joel McClure's record potato yields
Joel McClure, a Hugoton, Kan.,
strip-tiller, discovered this year that strip-tilling drove potato
yields to record levels, reports Guy Swanson, owner of Exactrix,
The nominal rate was 150 pounds of
nitrogen 60 pounds of phosphate, 40 pounds sulfur and (1 pound AZN.)
However, there were four lower rates used in the four
. Crop Quest agronomist Garrett Havel had
helped with the design of the VRT application for corn.
This is an unplanned discovery….since potatoes are never raised with NH3 and Polyphosphate….to my knowledge this is the only potato field in North America that has NH3 directly applied to it. Joel has broken a barrier…..that obviously will be tried in Washington and Idaho. Potato producers are fussy about nutrients…..Timing and Broadcast application…virtually no banding.
This serendipity could not have happened in Idaho, Oregon or Washington….not Alberta…..because serious corn producers seeking a much bigger net margin use NH3 and TAPPS….and avoid applying nutrients with a pivot. Strip Till is on the Mark….The question to Joel is. “Will he do it again”…..and what did the contractor of the potatoes think?
The is major breakthrough which will absolutely create a problem the fertilizer suppliers of PNW. ….and maybe Prosser or Pullman….or Moscow or Aberdeen…..will need to do a study.
