Sand is highly permeable to water; water flows through it easily. Clay is relatively waterproof, and water flows through it with great difficulty. This is because of the relative size of sand particles as compared to clay particles. Clay particles are extremely tiny, and therefore have much smaller gaps between them when they are packed together.
Sandy soil will allow more water to percolate compared to clayey soil. This is because sandy soil has larger particle sizes with more space between them, allowing water to flow through more easily. Clayey soil has smaller particle sizes with less space between them, leading to slower water percolation.
Clayey soil will allow less water to pass through compared to sandy soil because it has smaller particles and is more compact. This results in higher water retention in clayey soil and slower water infiltration compared to sandy soil.
Clayey soil will absorb more water than sandy soil. This is because clayey soil has smaller particles with more surface area, allowing it to retain water more effectively than sandy soil, which has larger particles with less surface area.
Loose or sandy soils allow water to percolate(pass) through them faster
Clayey soil has smaller particle size and higher surface area, allowing it to hold more water through capillary action compared to sandy soil. The smaller gaps between clay particles also slow down water drainage, leading to more water being retained in clayey soil.

Sandy soil is generally more susceptible to erosion than clayey soil. This is because sandy soil has larger particles and less cohesion between them, making it easier for water to wash away the soil particles. Clayey soil, with smaller particles that stick together more, is more resistant to erosion.
Sandy soils have larger particles with more space between them, allowing water to drain quickly and making them drier. In contrast, clayey soils have smaller particles which hold onto water more effectively, resulting in higher moisture content and less drainage, making them wetter.
Sandy soil will generally percolate water the fastest due to its large particle size and low clay content, allowing water to move through more quickly. Conversely, clay soil has smaller particles and higher water retention, leading to slower percolation.
Because the pore space (the space between soil particles) in sandy soil is so much larger. In sandy soils, the water is drawn by gravity downward and away from the roots quite easily, but in clay soils, the pore space is so much smaller that capillary action holds the water much more tightly. This is the same reason that clay soils flood more easily and take longer to dry out.
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.
Water that does not percolate into the ground can lead to surface runoff, which can erode soil and carry pollutants into bodies of water. It can also contribute to flooding and water accumulation in low-lying areas. It is important for water to percolate into the ground to recharge groundwater sources and support vegetation.
Sandy soil is too porous and allows leaching of nutrients below where the roots of the plants can reach it and will lead to poor growth. Clayey soil especially when hard will not enable the germinating seed planted to rise above the soil surface.
