SHUR-GRO™ (12-4-10-12S) Root System

vs.

Chemical (18-46-0) Root System

 

 

 

 

SHUR-GRO™ ears measure 20% longer than chemical ears, thus 20% larger yield.  Note purple stalks on chemical which is due to sugar imbalance caused by mineral imbalance in the soil.

 

SOIL ANALYSIS

 

Soil samples were taken between the roots of each stalk as the fertilizer was placed below the seed at plant time.  See test results below.

 

No bushel per acre test was made but is estimated at 150 bushel per acre on the Chemical and 170 Bushel per acre on the SHUR-GRO™.

Just the increase in phosphate and potash will result in an increase of fertility value.  The phosphate at $.20 per lb. ($7.20 more on SHUR-GRO™) and potash at $.10 per lb. ($3.40 more on SHUR-GRO™), thus a total increase in fertility of $10.60 per acre.  This along with a gain in protein at 2.4% definitely makes SHUR-GRO™ a much better buy for the money.
