Impact of Phosphorus Fertilizer Forms on Nutrition of Wheat, Pea and Canola, Soil Fate and Losses in Run-Off Water

Term: 4 years, beginning in 2021
Status: Ongoing

Total Project Cost: $339,892
Funding Partners: FAR, SPCDB, SWDC, Western Grains Research Foundation

Project Description

Knowledge on how new P fertilizer forms perform agronomically and environmentally as compared to traditional granular MAP. The study will compare 1) uncoated and 2) polymer coated mono-ammonium phosphate, 3) liquid ammonium polyphosphate, 4) diammonium phosphate, 5) triple superphosphate, 6) ammonium phosphate sulfate, 7) struvite and 8) granular rock phosphate in broadcast versus banded placement. Knowledge will encourage producers to decrease the practice of broadcasting P which is susceptible to the highest losses, and increase the adoption of 4R management practices.

Objective

  1. To assess how fertilizer phosphorus forms, placement, and rate affect crop responses, fate in the soil, and run-off losses in Saskatchewan soil.
