“…These findings are in agreement with the trends of deeper sola found in Black Chernozemic soil profiles than in the drier Brown and Dark Brown Chernozems (Landi et al 2003). The high proportion of profiles of the Black Chernozem Great Group at both Hidden Valley and Regina Beach suggest that increased equivalent latitude is associated with greater moisture availability.…”

Whitson, I. R. 2015. Equivalent latitude for prediction of soil development in a complex mapunit. Can. J. Soil Sci. 95: 125–137. Soil pattern in the Hillwash complex mapunit from Saskatchewan is too variable to be resolved spatially with conventional mapping approaches. The equivalent latitude metric allows identification of an index based on gradient and aspect that ranks sites based on differences in direct radiant energy inputs. Effects on soil development with reference to surface horizon color and soil classification were investigated at three study areas in southern Saskatchewan. At the first, sites with equivalent latitude greater than local latitude (north group) had a higher frequency of darker soil colors than sites where equivalent latitude was less than local latitude (south group). Black Chernozemic profiles made up nine of 13 profiles from the north group compared with none in the south group or in local controls. Similar color and classification trends in a north sample group were found at a second study area. Results from a third study area more than 200 km away and in a drier ecoregion found similar differences albeit a different set of subgroups between north and south group soils at that location. The equivalent latitude metric could be used in a GIS context to better resolve soil characteristics within this complex mapunit, but only after additional work to include a climate parameter such as potential transpiration into the model.

“…Water and energy limitations have been defined by the ratio of mean annual precipitation (MAP) to potential evapotranspiration (PET), or a MAP/PET ratio <1 in water-limited sites and MAP/PET >1 in energy-limited sites (Budyko, 1974). This transition can manifest as significant variations in primary production and soil development, with strong climate-related gradients in SOC stocks (Landi et al, 2003;Dai and Huang, 2006;Homann et al, 2007;Meier and Leuschner, 2010) and degree of soil development (Whittaker et al, 1968;Dahlgren et al, 1997;Bockheim et al, 2000;Egli et al, 2003;Rasmussen et al, 2007Rasmussen et al, , 2010Graham and O'Geen, 2010).…”

I n the hot, dry ecosystems of the southwestern United States, water availability and topography are central to understanding soil and landscape evolution. Water availability is the dominant driver of soil formation in water-limited climates where precipitation regulates soil production and erosion, vegetation distribution and primary production, soil organic C (SOC) storage, and the degree of primary mineral alteration to secondary products. Topography and landscape position are particularly important in water-limited systems through their control on the redistribution of limited water resources that can lead to significant variation in hillslope-scale soil development and physiochemical properties (Muhs, 1982). It is necessary to understand the coupling of soil, climate, and landscape position in the Desert Southwest where predicted changes in temperature extremes and precipitation variability may drive significant shifts in water availability and biological production (Seager et al., 2007; Intergovernmental Panel on Climate Change,

“…Lemenih et al (2005) demonstrate that soil C and total N contents in the 0-10 cm soil layer declined significantly in 53 years under cultivation compared to the natural forest. The OM loss within the last 80 years, on average is about 30% in Canadian Prairies (Anderson, 1995;Landi et al, 2003).…”

Soil quality is a concept that integrates soil biological, chemical, and physical factors into a framework for soil resource evaluation (Karlen et al., 1997). Larson and Pierce (1991) define soil quality as the capacity of a soil to function within the ecosystem boundaries and to interact positively with surrounding ecosystems. Conversion of forest and grasslands into agricultural land is one of the main concerns worldwide in the context of environmental degradation and global climate change (Wali et al., 1999). Conversion of natural land resources to crop production as the largest source of anthropogenic carbon emissions after fossil fuel burning, has resulted in the release of about 200 Pg C over the past 250 years, globally (Scholes and Noble, 2001; Fitzsimmons et al., 2004). It is also very well known that cultivation of the natural land resources brings about the loss of OM and this directly affects the soil chemical, physical, and biological properties resulting in loss of
