34. rocks. The same soil turns yellow when the iron diffused gets turned into hydrated form.
These soils occur generally in the drier regions of Eastern and Southern India and not in the
salts are brought from the shallow depth where the saline ground water table exists.
salination can be caused by natural processes such as mineral weathering or by the gradual
withdrawal of an ocean. It can also come about though artificial processes such as irrigation.
salinity from irrigation can occur over time wherever irrigation is used; since almost all
water (even natural rainfall) contains some dissolved salts. When the plants use the water,
dissolve chemicals and carry them into the underground water supply. Thus also causing
less irrigated or rainfall water as it has a very good capability to retain moisture.
The usage of manures and fertilizers per hectare is quite low in India compared to other
cannot much impact production provided electricity and water supply is made available for
the farmers.
Urad is drought resistant crop thus grown in regions even if the rainfall variability is very
states mentioned in the 2nd statement.
Well drained gentle sloped soils are required and rugged topography is not suitable for tea
Land holdings are very small due to inheritance law prevalent in the country and high
population mounts pressure on the land holdings to be utilized in an intensive way so as to
cater the demand for food from huge population. Farmers work with the help of family
labour and use of machinery is limited and most of the agricultural operations are done by
manual labour. Farm yard manure is used to maintain the fertility of the soil. In this type of
