10 A Review of the Use of the Basic Cation Saturation Ratio and the Ideal Soil * Our examination of data from numerous studies... would suggest that, within the ranges commonly found in soils, the chemical, physical, and biological fertility of a soil is generally not influenced by the ratios of Ca, Mg, and K. Cation ratios have no direct impact on yield key = maintain sufficient supply of nutrient cations in crop root zone at optimum base cation ratios, may still have nutrient deficiency or ph concern * Kopittke & Menzies, 2007, Soil Sci.
