★ O HORIZONS ------› It is that top organic layer of the soil mostly made up of leaf litter and humus this horizon is rich in humus.
★ A HORIZONS ------› This players are also called as top soil and is found below the O horizon. Seed germinate and plant grow in this dark coloured Layer. It is made up of humus ( decomposed organic matter ) mixed with mineral particles.
Sometimes , leaching of minerals and clay content takes place in the lower part of A horizon as water drips throw this region. This process of leaching is called evaluation .
