The anthropic horizon is a human-modified surface horizon that is rich in phosphorus due to long-term manuring or waste disposal, typically seen in ancient agricultural lands. This horizon is rare in India, whereas Mollic, Ochric, and Umbric horizons are common due to varied agro-climatic conditions. For example, Mollic is found in black soils, Ochric in arid/semi-arid regions, and Umbric in forest soils with high organic matter but lower base saturation.
