Corn Trials

RATE OF TREATMENT: 1/2 gallon per acre

This is a preliminary report on the overall success of the EnviroMax corn trials in 1997. Overall, we experienced a 10 to 20 bushel increase in yield on the test acres over the control acres. I am actually preparing an extensive and very detailed report. Due to the time that is required to write up the results in detail, it is not yet available.

We applied EnviroMax on several test fields this last year. On some fields we applied 1/2 gallon per acre at planting. On some fields we used one quart with our starter band (before or at planting), and one quart at fifth leaf, mixed with the fertilizer. In every case, our yields were increased by using EnviroMax. However, we did much better when we banded 1 quart at starter and 1 quart at fifth leaf.

The soil here generally is a pH of 7.4, and contains 1.6% to 2.0% organic matter. My final report will include the detail on this, field by field.

Our nutrient program was 28-0-0-5. Our clay soil has a cation exchange capacity of 29.2. On our sandy soil the cation exchange capacity ranges from 8.1 to 8.3.

In the sandy soil tests, we did not use the EnviroMax in band, so the results of the sandy soil tests are not as good as the results on clay. I personally believe the fact that EnviroMax increases porosity in clay will mean that in every case the yield difference between a control plot and test plot will be greater in a clay soil. However, due to the fact that we did not put EnviroMax down with the starter band on the sandy soil, we cannot be sure that we will not see an even better yield in 1998 when we use EnviroMax with the starter band in that soil type.

One final interesting fact pertains to a 125 acre field which had been badly damaged by hail. The hail arrived during pollination, which is the worst time. We did not expect much yield from the test field that was hit with the hail. Within 1 1/2 miles of that field, were four control field. None of those fields were hit with the hail. While I am not looking at the exact numbers, I can state that the test field that was hit with the hail outperformed the control fields (all four of them) in yield. Needless to say, we were amazed and elated at this result.
