Karamanos, R. E. and Puurveen, D. 2011. Evaluation of a polymer treatment as enhancer of phosphorus fertilizer efficiency in wheat. Can. J. Soil Sci. 91: 123-125. The effectiveness of Avail® was assessed in two 3-yr trials that included an unfertilized control and three rates of seed-placed P (6.5, 13 and 19.5 kg P ha-1) applied as monoammonium phosphate (MAP) with or without Avail®, and arranged in a randomized complete block design with six replications. Neither a significant effect of treating MAP with Avail® nor a significant interaction between Avail® treatment and rate of P on the yield of wheat and P uptake was observed.
