Weathered parent material accumulates in this layer, i.e. These areas of bedrock are under 50 feet of the other profiles. Unlike sandy soil, water can be held in the tiny gaps between the particles of clay. But they are heavy as they hold more water than the sandy soils. 4) Sandy soil has large particles with large spaces between them. The uppermost horizon is generally dark in colour as it is rich in humus and minerals. Water can drain quickly through the spaces between the sand particles. This works whether you have overly sandy or clayey soil. The size of the silt particles is between those of sand and clay. The Soil formation is mainly related to the parent rock material, surface relief, climate and natural vegetation. Each texture has very differ. It exhibits approximately equal properties of these three. Loamy soils are a mixture of sand,clay and silts. A vertical section through different layers of the soil is called the soil profile. On the other hand, there is an important agricultural difference between the coarse and fine silty and loamy classes, especially in terms of capillary rise and available moisture-holding capacity. These layers are referred to as is missing”. Based on their particle size, soils are classified into sandy, loamy, and clayey soils. Although it is not the same at every place on theearth. ‘Ideal’ soil is loam, a mixture of sand, silt and clay in the ratio of 40–40–20.
