Abstract

© Her Majesty the Queen in right of Canada 2017. Thirteen years after cultivating native grassland and establishing continuous wheat (Triticum aestivum L.) and wheat–fallow rotations in southern Alberta, surface soil total N levels were 15% lower, and nitrate (60–90 cm) concentrations were 2.5- and 17-fold greater, than native grassland. Wheat–fallow, even without fertilization, markedly enhanced potential nitrate loss through the root zone.
