coarse soil
Coarse soil can vary in color depending on the mineral composition present but it is commonly seen in hues of brown, red, or gray.
Coarse soil is typically a combination of sand and gravel particles. Sand particles are larger than silt and clay but smaller than gravel, while gravel particles are the largest of the three soil types.
Clay soil has fine particles, which are smaller than coarse particles such as sand. Clay particles are smaller than 0.002 mm in size, making the soil dense and able to retain moisture well due to its small particle size.
A dark-colored coarse soil might have a higher organic content due to decomposed plant matter, leading to better moisture retention and nutrient availability. On the other hand, a reddish smooth soil could indicate the presence of iron oxides, which may affect drainage and soil structure.
The falling head test is not suitable for coarse grained soils like gravel because the test requires a fine-grained soil that can create a seal at the base of the standpipe. Coarse grained soils like gravel do not form a tight seal, which can lead to inaccuracies in measuring the permeability of the soil sample. The test works best with fine-grained soils with low permeability.

Millets are known as coarse grains that can be grown on less fertile and sandy soil.
Coarse sand
it forms resistince from a hillslide
made up of course, large soil particles
In fine grained soil very fine particle are there which has got some chemical repulsion, these chemical repulsion does not allow particle to come closer due to which void ratio of fine grained soil is higher than coarse grained soil.

Clay soil has fine particles, which are smaller than coarse particles such as sand. Clay particles are smaller than 0.002 mm in size, making the soil dense and able to retain moisture well due to its small particle size.
It is a level, mostly treeless land that has fertile soil and coarse grass.

The possible causes for a change in the percolation rate of soil include soil's moisture content, topographic conditions, and the amount of coarse material in the soil.
