Results on Organica Lawn Booster and Microbial Soil Conditioner |
| Date: |
Oct. 27, 2003 |
We have completed the turf project, and I am sending the results in a separate file. I feel that the data in the report validates your product claims. Frankly, I am surprised that both the Lawn Booster and Microbial Soil Conditioner showed increased cumulative weight of cuttings, increased foliar nitrogen, and decreased nitrate in soil at the end of the experiment (indication of less nitrate leaching). The inoculation of the corn gluten (Lawn Booster) and the calcium (MSC) with your beneficial soil microorganisms certainly enhances the efficacy of the products.
In total, the results definitely support your product claims and I will stand by this report.
Sincerely,
Joseph W. Kloepper
