Both sides of the story

Company and university scientists disagree on CLP.

Do cross-linked poylacrylamides (CLPs) work as a soil amendment for relieving drought in row crops? The debate has been going on for decades. Today, the general consensus of university soil scientists is still “no,” or at best, “the material requires more research.” But a persistent company called American Soil Technologies (ASTI) says things are different this time and it has the data to prove it. University types need to let go of long-held preconceptions, it says. After Farm Industry News posted an article about the debate on this Web site a few months ago, ASTI requested the opportunity to post a rebuttal. We received that rebuttal yesterday and are posting it here unedited for your review and consideration.

Also posted is the Colorado State University research in question as well as an unedited letter to Farm Industry News from Grant Cardon, one of the lead researchers on that study.
