Question

Difference between Black soil and Coarse soil​

Answer 1

Answer:

black soil- Black soils are mineral soils which have a black surface horizon, enriched with organic carbon that is at least 25 cm deep. Two categories of black soils (1st and 2nd categories) are recognized. ... Organic carbon content in the upper 25-cm of the black horizons of ≥1.2% (or ≥ 0.6% for tropical regions) and ≤20%;

coarse soil- Coarse grained soils are defined as those soils whose individual grains are retained on a No. 200 (0.075 mm) sieve. Grains of this size can generally be seen with the naked eye, although a hand held magnifying glass may occasionally be needed to see the smallest of the grains. Gravel and sand are coarse grained soils.
