Lead Researcher (PI): Farrell, Richard
Institution: University of Saskatchewan
Total WGRF Funding: $131,051
Co-Funders: Alberta Wheat Commission, Saskatchewan Canola Development Commission, Saskatchewan Wheat Development Commission
Start Date: 2018
Project Length: 3 Years
Objectives:

1) Develop a rapid extraction procedure for easily extractable soil protein N (i.e., glomalin-related). 2) Develop a commercializable soil N test (based on the detection of easily-extractable soil protein) that could be licensed to others or developed further in-house. 3) Field test the procedure (small plot fertilizer N study) against other standard soil N tests and develop yield response curves for each to determine which test best correlates with crop yield.
