OBJECTIVE FORESTRY

Detailed explanation-1: -Sand, silt, and clay are the variation in sizes of the soil particles. Sand is the largest size and feels gritty. Silt is moderate in size and feels smooth or floury. Clay is the smallest particle and feels sticky.

Detailed explanation-2: -The bigger particle size of the sand gives wet or dry sandy soil a grainy texture when you rub it between your fingers, and it makes the soil light and crumbly even when you try to stick it together in your hand.

Detailed explanation-3: -Sandy soils contain large particles which are visible to the unaided eye, and are usually light in color. Sand feels coarse when wet or dry, and will not form a ball when squeezed in your fist. Sandy soils stay loose and allow moisture to penetrate easily, but do not retain it for long term us.

Detailed explanation-4: -Clay feels sticky when wet. It easily forms into a ball and a ribbon at least 5 cm long. Water drains very slowly through clay soil. Therefore, clay soil remains saturated after a heavy rain.
