20
Q
  1. Other uncultivated lands
A
  • permanent pastures and grazing lands
  • miscellaneous tree crops
  • cultruable waste lands (uncultivated > 5 agr years)
21
Q
  1. Fallow lands
A

Current fallow
1 or less agr year

Other than current
1-5 agr year

22
Q

Gross cropped area

A

area sown more than once in a year + net sown area

23
Q

Total geo area

A

3.28 million sq km

24
Q

Pattern of NSA

A

over 80% in Punjab Haryana

less than 10% Mizoram, Manipur, Andaman and Nicobar Islands, Arunachal

25
Q

Desired % of forest

A

33 of total geo area

National Forest Policy 1952

26
Q

__% of our basic needs for food shelter and clothing comes from land

A

95

27
Q

Land degradation in various states

A

> Deforestation due to mining
Jharkhand, Chhattisgarh, MP, Odisha

> Overgrazing
Gujarat, Rajasthan, MP, Maharashtra

> Over-irrigation (water logging increases salinity+alkalinity)
Punjab, Haryana, UP

28
Q

How does mineral processing degrade land

A

calcite, soapstone (ceramic industry)
limestone (cement ind)

dust

dust settles, hinders ability of water to infiltrate soil

29
Q

Ways to solve land degradation

A

Afforestation

Control grazing

> arid
Thorny bushes: sand dunes stabilisation
Shelter belts of plants

> urban, suburban
Treat industrial effluents and wastes before disposal
Control mining activities
management of waste lands

30
Q

Soil profile

A

Top Soil, upper soil layer

Subsoil weathered rock, sand, silt clay

Substratum weathered parent rock

Unweathered parent bed rock

31
Q

Alluvial soil: distribution

A

Northern plains (Indus Ganga Brahmaputra)
Extend to Rj Gj narrow corridor

Eastern coastal plains (Godavari Krishna Mahanadi Kaveri deltas)

32
Q

Chos, Duars and Terai?

A

alluvial soils found in Piedmont plains which are coarse especially in the upper reaches of the river valley

33
Q

Alluvial soil based on age

A

Bangar
OLD
- more kanker nodules

Khadar
NEW
- more fine particles
- more fertile

34
Q

Alluvial soil usage

A

Right proportion of potash lime and phosphoric acid

ideal for sugarcane, paddy, wheat, cereals, pulses

intensively cultivated and densely populated

35
Q

Black soil distribution

A

Deccan trap (basalt) region
NW deccan plateau

Maharashtra, MP, Malwa, Saurashtra, Chhattisgarh

36
Q

Black soil properties

A

aka regur soils, black cotton soil

made of extremely fine clayey material

hold moisture well

rich in calcium carbonate, Mg, potash, lime
poor in phosphoric content

deep cracks in hot weather= proper aeration of soil

sticky when wet:: diff to work with unless immediately tilled after the first shower/pre monsoon

37
Q

Red and yellow soils

A

low rainfall, on crystalline igneous rocks

east and south deccan

odisha, chhattisgarh, south ganga plain, piedmont western ghats

red due to diffusion of iron in crystalline and metamorphic rocks

yellow hydrated form

38
Q

Laterite soil

A

Latin, later = brick

devs in tropical/subtropical climate w alternate wet and dry season

result of intense leaching due to heavy rain

deep- very deep,

acidic

deficient in nutrients

humus rich w deci and evergreen forests, vice versa

prone to degradation and erosion

TN kerala kntk coffee cashew AP

39
Q

Laterite soil distribution and usage

A

> mhrhtra, kerala, TN, odisha, WB, NE region

humus rich: support deciduous and evergreen forests
humus poor: sparse vege, semi arid

prone to erosion and degradation due to position of landscape

TN, Kerala, Karnataka : coffee + tea (appropriate soil cons techniques)

Red laterite TN Andhra P Kerala: cashew

40
Q

Arid

A

red-brown color

sandy

saline (salt can be obtained sometimes)

lacks humus and moisture

lower horizons= kankar (increasing calcium content downwards)
restricts infiltration of water

irrigation>cultivable Rj

41
Q

Forest soils

A

Hilly/mountainous areas, rain forests available

Valley: loamy + silty

Upper slopes: coarse grained

Snow covered himalayas: denudation, acidic, low humus

Lower valley (esp river terraces and alluvial fans): fertile

42
Q

Soil erosion

A

denudation of soil cover and subsequent washing down

43
Q

Causes of s erosion

A

man made
over grazing
deforestation
mining
construction

natural
wind
water
glacier

44
Q

different ways of soil erosion

A

water, clayey soil: deep channels, gullies
unfit for cult, bad land
chambal basin: ravines

sheet erosion
water flows as a sheet
top soil washed

wind erosion
blows loose soil off flat/sloping land

ploughing up/down the slope
channels for quick flow of water, erosion

45
Q

soil erosion solutions

A

contour ploughing
ploughing along contour lines to decelerate flow of water

terrace farming
steps cut on slopes
western and central himalayas well deved

Strip cropping
strips of grass are made to grow in between crops to stop the force of wind

Shelter belts
planting lines of trees
stabilisation of sand dunes/desert western india
