Soil X has a texture of 40 % sand, 30 % silt and 30 % clay, while Soil Y contains 20 % sand, 50 % silt and 30 % clay. Using the empirical relations \[\text{FC}=0.2\,\%\text{clay}+0.1\,\%\text{silt}+0.05\,\%\text{sand},\qquad \text{WP}=0.1\,\%\text{clay}+0.05\,\%\text{silt}+0.02\,\%\text{sand},\] where FC and WP are expressed as percentages of water content, determine which soil has the greater available water capacity (AWC = FC - WP) and state the difference in AWC between the two soils (in percentage points, to one decimal place).
