Can foliar urea reduce nitrogen losses from potato production in Atlantic Canada?

IPNI-2014-CAN-4RC04

Description of Activity and Deliverables: This activity in the proposed 4R Nutrient Stewardship Research Network project focuses on a major horticultural crop for Canada and Maritime Canada, potato. Potato is a unique cropping system prone to major N losses because of high N application rates, coarse soil and humid conditions. The project aims to manage the availability of nitrate for better crop uptake and reduction in nitrous oxide emissions and leaching. Read more

Interpretive Summary

In recent years it has become increasingly popular for potato producers in Atlantic Canada to include urea in the foliar applications of fungicides. Producers believe this practice sustains their potato crop through periods of water stress and allows for more rapid recovery following a precipitation event. This urea application is not considered as part of their N fertility program and is applied in addition to the recommended rates of N fertilizer at planting.
