Enhancing Phosphate Fertility
Phosphate uptake by corn, especially in the spring, is critical
for achieving optimum yields. To help improve P availability,
a new tool in the fertility toolbox is JumpStart.
JumpStart enhances phosphate efficiency. It contains the
naturally occurring soil fungus Penicillium bilaii, which was
discovered by Agriculture and Agri-Food Canada. JumpStart
is a wettable powder that is applied as a seed treatment
prior to seeding. It colonizes plant roots and makes the ‘fixed’ mineral forms of less available soil phosphate
immediately available for crop use. The result is higher corn
yields and a better return on your fertilizer investment.
JumpStart improves corn growth
JumpStart helps ensure that adequate phosphate nutrition is
available at four critical growth stages:
1. Emergence and stand establishment -JumpStart helps to
get the crop out of the ground fast.
2. Rapid growth - the root system that JumpStart helps
develop, equips the plant to better handle stresses such as
drought and poor fertility.
3. Pollination - where the potential yield is established,
JumpStart increases root growth, which reduces the
effects of drought helping to keep pollen shed and silk
emergence synchronized.
4. Grain fill and kernel development - when the number of
kernels per row is strongly influenced by plant nutrition,
JumpStart helps ensure phosphate is readily available.
Quick emergence and early vigor
Cool soil and/or residues greater than 30%, which are
common under reduced tillage or early seeding, means
phosphate is less available to plants. If early season
phosphate availability is limited, it can reduce early season
growth, and ultimately crop yield.
JumpStart is active in cool soils (as low as 40˚ F), and supplies
an immediately available source of phosphate to merging
seedlings. In other crops (wheat, canola, pea, lentil and
alfalfa), JumpStart has been proven to increase crop growth
by 7% at 3 to 4 weeks after emergence.
Fast emergence is especially important where long-season
hybrids are planted in cooler season areas. Proper
phosphate nutrition means your crop is ready to achieve its
full yield potential.
JumpStart Performance 39 trials conducted since 2003 prove the performance of JumpStart on corn.

¹Net returns were calculated using 5 year average (2000-2004) US commodity prices for crops and fertilizer less the 2005 suggested retail price for JumpStart. Average yield response applied to a target yield of 150bu/ac to calculate net return/acre on corn.
JumpStart Application
JumpStart is sold as a wettable powder that is mixed into water and applied to the seed prior to seeding.
