More often, the sand particles are more solid and larger than all the other particles included in the mixture, allowing … Loam soils have a slower water absorption rate, soaking up from .25 to 2 inches an hour. Nutrients like potassium and ammonium have positive charges. For example, pedology is the scientific study of soils. Sandy soils, which are extremely porous, have the greatest penetration depth, absorbing more than two inches of water each hour. (Soils that are predominantly silt or clay feel floury or sticky respectively.) These are also areas where puddles form because the water is not able to drain away. However, they can become very hard if they dry out. It is best to avoid very light soils as these can … Because sandy soil contains large particles that are irregularly shaped, grains don't fit together compactly, leaving a lot of air space compared to silt and clay.
