SOIL TEXTURE.
The soil is made mp OF very small
-srIc'es called soil grains. Those In

sand about 80 will make an inch
The texture OF "a soil depends upon
.hs size Of its grains and the way in
which they are grouped into COM
pound clusters or kernels. In all
agriculture soils, no soil grain is sep
arated from the other grains. They
arc grouped together, forming larger
kernels and the size Of these COM
pound kernels determines the tex
