Detailed explanation-1: -One way to identify soil texture is to take a pinch of soil and wet it gradually, whilst kneading it between your fingers and thumb, until there is enough moisture to hold the soil together and the soil is cohesive and sticks together.
Detailed explanation-2: -Rub soil between fingers to feel for grittiness. Very gritty . . . then it’s a SANDY CLAY. Very smooth . . . then it’s a CLAY. Neither gritty or smooth . . . then it’s a SILTY CLAY.
Detailed explanation-3: -Sandy loam The sand in these soils cannot be seen with the naked eye but can be felt when rubbed between the fingers. A scratchy noise may be heard when the ball is manipulated between the fingers.
Detailed explanation-4: -Take about 2 tablespoons of soil in one hand and add water, drop by drop, while working the soil until it reaches a sticky consistency. Squeeze the wetted soil between thumb and forefinger to form a flat ribbon. More items •24-Sept-2013
