The horizon that stores leached nutrients and minerals is the B horizon. The B horizon, also known as the subsoil, accumulates materials that have leached down from the upper layers (A and O horizons) and often contains minerals and nutrients that have been deposited from above. The A horizon, or topsoil, contains organic material and is where most biological activity occurs, while the O horizon consists mainly of organic matter such as decomposed leaves and plant material.
Which horizon stores leached nutrients and minerals?
