County-Scale Spatial Variability of Macronutrient Availability Ratios in Paddy Soils
Figure 5
Spatial distribution maps of availability ratios of N (a), P (b), and K (c). Note that (a) is derived from Figures 4(a) and 4(b), (b) is derived from Figures 4(c) and 4(d), and (c) is derived from Figures 4(e) and 4(f).
