Explore more about: Preparation of Soil for Agriculture. Apart from the rocks, minerals, and layers, soil profile also consists of a water content, which is referred to as soil moisture. A soil is simply a porous medium consisting of minerals, water, gases, organic matter, and microorganisms. 1. Mineral - The largest component of soil is the mineral portion, which makes up approximately 45% to 49% of the volume. 2. Water - Water is the second basic component of soil. Water can make up approximately 2% to 50% of the soil volume. 3.Newly formed "immature" soils may only have an O-A-C sequence while older more "mature" soils display the full profile of horizons as described above. The particular compositional, structural and chemical composition of the soil depends on the various factors that influence soil formation.Question: A soil profile consists of 6 m of coarse sand overlying 4 m of firm clay (below the clay there is the bedrock).

The sand is estimated to have an average dry unit weight of 18 kN/m^3 over its full thickness, and to be saturatedSolution. The soil profile is the layers of soil found when we go deeper into the ground. There are three main layers of soil – top soil, subsoil and parent rock. Topsoil ( A – horizon): Top soil is the upper most layer of the soil which is made up of humus and small particles of rocks. It is dark in colour due to the presence of humus.A typical soil profile takes nearly 1,000 to 100,000 years to form. A soil profile comprises 5 major soil horizons (i.e., layers). They are the O, A, B, C and R horizons. Figure 1: A typical soil profile O Horizon: (1st layer) This is the top layer of soil. It is made of fresh to partially decomposed organic matter.
