Question : 23 [SSC IT 2004]
For the cultivation of Tobacco the soil should be rich in
a) organic content
b) potash
c) calcareous matter
d) nitrogen
Answer »Answer: (b)
Tobacco is a crop that needs significant amounts of potassium. It is a fast-growing plant, between 80 and 150 days, with a high daily potassium requirement. Potash is the common name for various mined and manufactured salts that contain potassium in water-soluble form.
In some rare cases, potash can be formed with traces of organic materials such as plant remains, and this was the major historical source for it before the industrial era.
Question : 24 [SSC CGL 2010]
Soil erosion on hill slopes can be checked by
a) Strip cropping
b) Contour ploughing
c) Afforestation
d) Terrace cultivation
Answer »Answer: (d)
Terrace farming is a type of farming that was developed first by the Inca people. This method of farming uses “steps”, called Andenes that are built into the side of a mountain or hill.
On each anden, various crops are planted, and when it rains, instead of washing away all of the nutrients in the soil, the nutrients are carried down to the next level.
Additionally, these “steps” prevent a free-flowing avalanche of water that would take plants with it and destroy all of the crops on the hillside.
