Evaluation of Phosphate and Nitrogen Fertilizers Treated with Polymer Additives to Increase Fertilizer Efficiency

The Richardson International Kelburn, MB research and demonstration farm was the site of experiments evaluating Avail additive for both dry granular and liquid phosphate fertilizers. there were also experiments evaluating Nutrisphere additive for urea N fertilizer.

IPNI-2008-CAN-MB21

The study will be located on Grey Luvisolic soils near Dawson Creek, BC and Breton, AB with clay loam textured soils; and Black Chernozemic soils near Edmonton, AB, Indian Head, SK and Howden, MB with clay, loam, and clay textured soils respectively. The Avail-P experiments will consist of a randomized complete block (RCB) design replicated four times at each site and include the seed row fertilizer treatments listed in the Table 1 below.

Interpretive Summary

2008

Evaluation of Phosphate and Nitrogen Fertilizers Treated with Polymer Additives to Increase Fertilizer Efficiency in Manitoba, 2008 This project consisted of two field research experiments. One evaluated the effect of adding the Avail® polymer additive to granular and liquid phosphate fertilizers. The second project evaluated the effect of adding the Nutrisphere® polymer additive to granular urea fertilizer. This study was initiated in April 2008.
