Corn Research Study Results - 2003
Martinsville, Illinois

This year’s corn trial in Martinsville, Illinois showed dramatic yield differences between treatments. Pellet Lime was applied in treatments 1 and 3 at the neutralization rate for nitrogen. Treatments 1 and 2 received a corn maintenance application of P/K fertilizer. All plots received 150 pounds of nitrogen. Treatment 4 is the control with only nitrogen applied. Overall fertility is good while the average beginning soil pH is 6.0.


Randomized complete block design; 4 replications; P1 28 ppm,
K 138 ppm, Soil pH 6.0, CEC 11, OM 2.1

Comments
Evidence has suggested in these trials that nitrogen use efficiency increases with the addition of Pellet Lime. Also believed is adequate plant calcium lessens the impact of key damaging diseases in crops. Calcium has important roles in the integrity of cell walls which works as a resistance mechanism to reduce penetration of diseases. Any plant that is void of nutrient stresses will be in a position to resist the attack of pathogens and out-grow disease.

Results in this year’s study show that Treatment 1 (maintenance application of P/K, 150 units of Nitrogen and 250 pounds of Pellet Lime) out-yielded the control plots by nearly 29 bushels/acre. Treatment1 (with Pellet Lime) also out-performed Treatment 2 (no Pellet Lime) by over 8 bushels. This year’s study strongly shows corn is responsive to broadcast applications of Pellet Lime.
