I feel to properly test Pivo Bio.... the following test strips need to be used.   With replication.   In fields of varying nutrient levels.  With varying growing seasons.  

1.    Pivot Bio with normal nitrogen rates used.

2.    Pivot Bio with a reduction of 40 pounds of nitrogen used.

3.    No Pivot Bio used with normal nitrogen rates used.

4.    No Pivot Bio with a reduction of 40 pounds of nitrogen used.


I fear too often those reporting results for Pivot Bio aren't running strips without Pivot Bio, with 40 pounds less of nitrogen.   Maybe we can get the same corn yield with 40 pounds less of nitrogen, without Pivot Bio.  Need to make that comparison to know.
