Good Afternoon List Friends.
I found this link on the AnimalNet clipping service out of the
University of Guelph.
http://www.ars.usda.gov/is/AR/archive/jul04/water0704.htm
It tells of USDA Ag Research which suggests that, "...an alum-based
water-treatment residual increases soil's capacity to adsorb (bond)
phosphorus, a vital plant nutrient. Increased adsorption of phosphorus
would curb its runoff, which can lower the oxygen content of water
bodies and spoil the taste of drinking water."
Since phosphorus overload from manure application is also becoming an
increasing problem, this may help to alleviate the problem.
