A vertically-resolved Canadian prairie soil and nutrient analytical archive. Most fertility packages are sold as a surface plus subsurface two-depth bundle, so each field yields a soil profile rather than a single topsoil reading: nitrate-N, P, K, sulphate-S, pH and EC at surface with N, S, pH and EC at depth. Two extraction methodologies are offered (standard and Morgan/M3, the latter adding Ca, Mg, Na, base saturation, CEC, Fe, Cu, Zn, B, Mn and aluminium), alongside plant tissue mineral panels, liquid manure nutrient assays, soil biology and soil organic carbon testing for sustainability programmes.
