Effect Of Avail® Polymer Applied To Phosphorus Fertilizers On Dry Matter Production And P Uptake Of Fescue At Princeton, Ky, Lloyd W. Murdock, John James Olson, Gene Olson
Soil Science News and Views
A study was conducted near Princeton, KY to determine if a polymer (AVAIL®) applied to diammonium phosphate (DAP, 18- 46-0) and mono ammonium phosphate (MAP, 11-52-0) would increase (P) phosphorus use efficiency in fescue production on a low P testing soil, when compared to an untreated phosphate fertilizer. AVAIL® (Specialty Fertilizer Products, Belton, MO) is presently being sold in Kentucky as a product to improve phosphorus fertilizer efficiency.

The ability to control physical and mechanical properties of polymer systems has become an important aspect of polymer science. In order to tailor the branching in polymer systems, an understanding into the reactivity of the electrophilic sites in the monomer is important. Kinetic methods have been explored in order to determine the reactivity of monomers in preparing poly(arylene ether)s and to predict the degree of branching that will occur in a polymer of this kind. The reactivity of AB2 sulfones and phosphine oxides was explored, along with the reactivity of ABB'B'' sulfones. NMR spectroscopy was used as a probe into …
