What is Nitosols soil?
A nitisol in the World Reference Base for Soil Resources (WRB) is a deep, red, well-drained soil with a clay content of more than 30% and a blocky structure. Nitisols correlate with the kandic alfisols, ultisols and inceptisols of the USDA soil taxonomy.
What is Leptosol soil?
Leptosols are soils with a very shallow profile depth (indicating little influence of soil-forming processes), and they often contain large amounts of gravel. They typically remain under natural vegetation, being especially susceptible to erosion, desiccation, or waterlogging, depending on climate and topography.

Loam soils seem to be the jackpot for all farmers. They include clay, sand, and silt and is the best possible combination of all negative and positive features. It is regarded as the best type of soil and is more gardener-friendly than any others as it does not require any additional investments.
What is Cambisols in Ethiopia?
The second group of soils; Cambisols and Luvisols, are found in the Simien plateau of the Western Highlands. They are highly weathered with a subsurface accumulation of clay and are characterized by low nutrient retention, surface crusting, and erosion hazards.
What is soil Upsc?

The major factors that determine soils’ characteristics are parent material, climate, relief, vegetation, time, and some other life-forms. Major constituents of the soil are mineral particles, humus, water, and air.
