Abstract
Soil properties and crop characteristics were measured in a two-year study at Indian Head, Saskatchewan. A one-acre sampling grid (308 sampling points) was established in eight plots representing phases of a canola-wheat-pulse-wheat rotation. Spatial and statistical variability of soil nitrate nitrogen, phosphorus and potassium were related to crop yield, hyperspectral reflectance (460, 510, 560, 610, 660, 710, 760, 810 nm) and radiation transmitted through the leaf (650 and 940 nm). Soil nitrate-N, depth to primary and secondary carbonates varied throughout the field and appeared to reflect a combination of erosion and tillage. Slight to moderate salinity was observed in a depression, located in the centre of the field.
