Corn Research Study Results - 2004
Martinsville, Illinois

Two years running we have achieved significant responses to corn with the application of Pellet Lime.
With excellent corn growing conditions in 2004, the Pellet Lime - NPK treatments out-yielded those without Pellet Lime by over 12 Bushels/Acre and the 2-year average shows an increase of over 10 Bushels/Acre.

Recommendations for this study follow the soil pH maintenance concept.
This involves applying approximately 2 pounds of Pellet Lime in order to offset the acidity caused by each pound of ammonia nitrogen.

Comments
Results in the two-year average of this study show that Treatment 1 (maintenance application of N/P/K and 250 pounds of Pellet Lime out-yielded Treatment 2 without Pellet Lime by 10.14 bushels/acre. This difference is statistically significant and shows what the addition of Pellet Lime can contribute towards maximizing yields. An interesting observation is that Treatment 3 using only nitrogen and Pellet Lime compares similarly in yield to Treatment 2 which contains maintenance N/P/K. This could be due in part to the theory that nitrogen use efficiency increases with the addition of calcium packed Pellet Lime.
