Product Performance Trials
JumpStart Performance Frequency Graph
JumpStart has been extensively tested since 1988 in over 310 farmer applied split-field trials. Some time the results are too good to be true and some time the results are too bad to be true, but over time and many trials an expected response emerges as shown by the frequency graph below.
Across a number of crops over 18 years of testing and at a 95% confidence level, we expect that JumpStart will result in a yield increase of between 6.4% and 8.6% 19 times out of 20.
The consistency of response to JumpStart is as consistent as a response to phosphate fertilizer.
Trial Summary
310 trials over the 18 years prove the performance of JumpStart on a wide variety of crops.

¹Net returns were calculated using 5 year average (2000-2004) US commodity prices for crops and fertilizer less the 2006 suggested retail price for JumpStart.
²Average yield response applied to a target yield of 150 bu/ac to calculate net return/acre on corn.
3Total and average of wheat, winter wheat, canola and pea/lentil trials.
495% confidence limit is $1.31 per acre. This means the net return for all crops will range between $4.20 and $8.63 per acre 19 times out of 20.
5Average P fertilizer difference is 15.1 lbs P2O5 per acre on the no JumpStart control strips.
