Dairy farms need to improve their environmental performance to justify continued consumption of dairy products. Previous studies have demonstrated improved re-use of dairy slurry nitrogen (N) and phosphorous (P) by separating solid and liquid fractio

National inventory reporting of agricultural nitrous oxide (N2O) emissions in Canada is based primarily on measurements obtained using static chambers. In regions with cold winters and an accumulated snowpack (including Canada), these measurements te

A field study was conducted near Saskatoon, Canada, where area- and yield-scaled N2O emissions were evaluated for two rotation cycles of four pulse crops (chickpea [Cicer arietinum L.], faba bean [Vicia faba L.], lentil [Lens culinaris L.], and field

Climate change, agricultural inputs, cropping diversity, and environment have seldom been combined in analyses of soil organic carbon (SOC), and soil C respired through microbial respiration (MR). This modeling study assessed SOC and MR simulated wit

Crop rotations on the Canadian prairies commonly include sequences of pulses, oilseeds, and cereals; however, limited information is available regarding the influence that different crop types and sequences may have on direct nitrous oxide (N2O) emis

Greenhouse gas (GHG) emissions from agricultural soils in the Canadian Prairie region are generally low and, due to dry, well aerated soil conditions, can be quite variable. Compared to dryland (rainfed) crop production, irrigated cropping has potent

In order to identify strategies to support global food security while protecting the environment under future climate in northern high latitude environments such as the Canadian Prairies, the DAYCENT model was calibrated, validated, and subsequently
