The plots' soil chemistry is discussed in detail in [24] (see their Appendix L for original soil ... chemistry data). In general soil nutrient stocks (P, K, Ca) are higher on the old alluvial soils compared to residual soils, and increase downslope from ridgetops to swales on the residual soils [24]. While
