Which soil texture index is more useful in evaluation of the relationship between soil texture and spatial soil moisture pattern?
I want to evaluate the dependency of the spatial soil moisture pattern to soil texture. it seems better to use a specific index that includes all three variables of clay, silt and sand.
many thanks!
A link is provided, see it to finally decide:

Hi Hussein, you will consider clay fraction or texture containing clay than others as clay retains more water than other fractions.
Abdul link also, provide you with textural code (figure) to fit into formulae or system to see the spatial variability of the soil texture.
I agree with Abdul link given above and Effiom suggestion. Clay fractions play a significant role in the spatial soil moisture pattern to soil texture in the field
(% silt + % clay) is a widely used, single, and simple variable that roughly summarises the water and nutrient retention of the mineral part of a soil
