Clay. Scanning electron microscope of a sample of clay. Clay particles are the smallest particle of the different soil types,giving the soil a smooth feel when rubbed between the fingers. Such small particle sizes means that water cannot drain easily through clay soils,resulting in land with poor drainage. For this reason,clays are known as 'heavy' soils,because they are heavy to work. Clay soils are usually very fertile,however | |
