What is the difference between alluvial soil and the black soil
The difference between soil fertility and soil productivity is that soil fertility involves the soils and fertilizing them per the types of plants, crops, and soils, being used. The soil productivity has to do with the drainage of the soils, the amounts and types of fertilizers, and the progress of the plants and crops due to fertilization.
Soil fertility is the ability of soil to produce crops. Soil productivity is the soils ability to yield a certain amount of crops.
cohesive soils are those soils where the attraction between the soil particles is very high such as in clay. non-cohesive soils are those soils where there is no firm attraction between the soil particles.
Young soils without distinguishable soil horizons, such as you would find with scree soils at the base of a mountain or on a sand dune.
Erosion... the young soil from mountains eroded during floods and the soil transfer from the lower lands..
All soils come from a parent rock. The parent rock is broken down due to weathering, will eventually after many years will become a fine crumbly soil. Different parent rocks produce different soils.
In clay soils are very small gaps between the rock particles, and so clay soils do not drain well. In sandy soils there are bigger gaps between the particles, allowing the soil to drain well and contain enough air.
podsolic soils,latosolic soil,chernozemic soils,desert soil and latosolic soil.
Fluvial soils are associated with streams and rivers. The Alluvial soil category is primarily composed of unconsolidated basin fill that has been deposited and then altered by water.
the deserts soil is very thin and dry as the forest soil is very wet and muggy Due to the lack of water in deserts, not many plants can grow there. Therefore, there can never be much accumulation of biomass for compost. So desert soils are always much thinner and less able to hold water than forest soils.
