best example of cohesive soil is the soil which have high content of clay or clay.
Soils with a high clay content are poor draining and run off and standing surface water is likely.
Clay soils can absorb water, but do so only slowly because they are very fine grained, and the spaces between the grains are very small. This is in contrast to sandy soils where the spaces are big and water penetrates easily. During periods of heavy rain you can quickly get standing water on the surface of clay soils, which soon leads to run-off.
Sandy soils are much more permeable that clay soils.
The sandy soils let the water pass through but the clay soils hold the water

Sandy soils are generally less fertile than clay soils because they do not hold water as well as clay soils. Clay soils are usually fertile and hold more nutrients than sandy soils.
Sand content is part of many different native "soils", but they are not exactly the same thing. Loam soil - the best kind for growing things - is made up of fairly equal proportions of sand, silt, clay and organic matter. Some soils are high in clay (called "heavy" soils). Some soils are high in sand content - the soil in my own yard for example. So in a sentence: Sand is a component of most soils - it is not "soil" by itself.
clay soils, loamy soils and sandy soils
Water can easily move through sandy soils, wheras clay-rich soil is much harder for water to penetrate, so sandy soils are drier.
Sandy soils are generally less fertile than clay soils because they do not hold water as well as clay soils. Clay soils are usually fertile and hold more nutrients than sandy soils.
Clay soil is so sticky because its make-up attracts higher water content than other soils. However, clay does NOT have good drainage like that in other soils. The stickiness does NOT make clay a good soil for planting of any kind, whether food seeds or flowering plants.
clay defined as fine grained soils-size of soils is passing 2mm seive with 10% soils retained on a 2mm seive.
