Weathering is the process of formation of soil, it is a slow process. B-Horizon is the second layer of soil, it is known as subsoil. Clayey soil has good water holding capacity, it has very small air space. Percolation is the rate at which water passes through any material, it is linked to the porosity of soil. Pulses grow well in the loamy soil, it is the soil that is best for growing plants. Column A Column B 1. Weathering D. Slow process 2. B-horizon A. Subsoil 3. Clayey soil B. Very small air space 4.
