Zack Frederick (MHPEC Inc) explains the newest results and future goals in the ongoing project to define and treat yield variability that is observed in grower processing potato fields in Manitoba.
Zack Frederick explains how the FVS study identified soil nitrogen deficiencies at row closure that have been associated with decreased yield of certain tuber sizes. This study is part of an ongoing effort to raise soil nitrogen at row closure above 120 lbs/A to verify the association and demonstrate methods growers can use.
Zack Frederick covers how the FVS study found an association between soil sulphur deficiencies at row closure and decreased yield of certain tuber sizes. This study is part of the framework to raise soil sulphur throughout the production season, but especially at row closure to maintain at least 30 lbs of sulphur in the soil.
Haider Abbas describes a new component of the nitrogen remediation study with monitoring wells called Piezometers, which is used to monitor nitrogen leaching potential.
Zack Frederick and Haider Abbas (Manitoba Agriculture) provide updates on a cooperative set of experiments with the goal of growing the most mustard biomass and biofumigate processing potato field soils as a management tool for Verticillium wilt. These experiments include plot work at the Canada Manitoba Crop Diversification Centre (CMCDC) in Carberry, Man. and field-scale experiments with growers in production fields.
