Inceptisols, Entisols, Vertisols and Mollisols are orders of which one of the following ?

Inceptisols, Entisols, Vertisols, and Mollisols are specific orders within the USDA Soil Taxonomy system, which is a global standard for soil classification [1]. This system identifies twelve distinct soil orders based on their physical, chemical, and biological properties [1]. Inceptisols represent soils with minimal horizon development, while Entisols are soils of recent origin with little to no development [4]. Vertisols are characterized by high clay content that causes significant cracking during dry seasons [4]. Mollisols are highly fertile, organic-rich soils typically found in grassland ecosystems [3]. In the Indian context, Inceptisols and Entisols are among the most widely distributed soil orders, covering a significant percentage of the country's geographical area [1]. These classifications help scientists and agriculturists understand soil fertility, age, and suitability for various land uses.
