Clark, SD | I've used PB for the last 3 years, won't use it again unless they can provide actual verifiable data. The only data that they have shows more biomass and more in season N levels, but no yield increase. Which is a huge red flag there. I've seen little bumps but nothing that would show you're getting 40 unit of nitrogen from PB. Plus at current N prices, PB is already higher then synthetic N and that calculating PB at 40 units....which has never been proven (ironic that they call it ProveN 40). Once you start calculating you may only get 0-10 bushel increase from PB, that N starts getting really expensive. | |

Pivot bio or other nitrogen biological versus in furrow N
