A laboratory study on the effects of soil moisture content, texture, and timing of leaching on N loss from two Southern Alberta soils


, : A laboratory study on the effects of soil moisture content, texture, and timing of leaching on N loss from two Southern Alberta soils. Canadian Journal of Soil Science 62(2): 407-413

A column study was conducted to determine the effects of soil texture, initial soil moisture content and timing of leaching on N removal from two irrigated soils of southern Alberta. Pelleted NH4NO3 fertilizer (0.639 g N per column = 336 kg.ha-1) was applied to Lethbridge loam and Cavendish fine sandy loam at three initial levels of soil moisture: air dry, 0.5 field capacity, and wet (25 cm suction). Leaching began immediately after the fertilizer application or was delayed 1 wk.
