  TSM® started renting this field in 1997. It was in poor condition and a lot of people said it would never produce more than 100 bushels of corn per acre. That first year we averaged 119 bu/acre using the TSM® program. Now, after 12 years, this field has produced 232 bu/acre.

The purpose of the 2008 corn and soybean hybrid trials is to showcase some of the main varieties produced by DeKalb® and Dyna-Gro®, and to determine the best hybrids for growing in East Central Illinois.

The TSM® E budget was the fertility program used. (The various budget levels of the TSM® program are explained in the topic "Fertilizer Budgets".) Soil analysis was done by A&L Great Lakes Laboratories in Fort Wayne, Indiana.

The following amounts of fertilizer were applied:
    DAP - 75 lbs/A
    Potash - 150 lbs/A
    TSM® Micronutrients - 50 lbs/A
    ESN nitrogen - 455 lbs/A (200 lbs actual nitrogen/A)

Degree ExtraTM and Roundup PowerMAXTM herbicides were used at recommended rates on this field. Aztec® insecticide was applied at planting even though all these corn hybrids have corn rootworm tolerance.
