LAND RESOURCES AND SOIL.
IN THIS
PRESANTATION
WE WILL COVER
IMPORTANT
TOPICS ABOUT
LAND RESOURCES
AND SOIL.
WHAT IS LAND RESOURCE ?
• Natural resources in the form of arable land.
• We are totally depended on land
for food, clothing and shelter.

LAND UTILISATION
• Land resources used by following purpose are:
• Agriculture & Forest.
• Barren and Wasteland (Building, factories &
etc.)
• Fallow land.
• Net sown area.
Land use pattern in India.
• In India use of land is determined by both
physical factor such as topography , climate,
soil type as well as human factor such as
population density, technological capability
and culture and traditions.
Land Degradation and Conservation
Measures.
• Land degradation is a process in which the
value of the biophysical environment is
affected by a combination of human-induced
processes acting upon the land.
• Conservation measures to taken up :-
• Afforestation and proper management of
grazing.
• Proper management of wasteland.
SOIL AS RESOURCE.
• SOIL is the most important renewable natural
resource .
• Soil is the mixture of minerals, organic matter,
gases, liquids and a myriad of organisms that
can support plant life.
Soil Profile.
Classification of Soil.
• Alluvial soil
• Black soil
• Red and yellow soil
• Laterite soil
• Arid soil
• Forest soil
ALLUVIAL SOIL.
• Covering about 45.6% geographical area in India.
• Made up of silt , sand and clay.
• Rich in nutrients like potash , phosphoric acid and
lime
• Due to high fertility , area having soil are
intensely cultivated and highly populated.
• OLDER ALLUVIAL SOIL-BANGAR
• NEWER ALLUVIAL SOIL - KHADAR
Black soil( regur soil )
• Made up of extremely fine clayey material.
• It develops the deep cracks during summer
season which helps in aeration of soil became
sticky ( due to high moisture ) when wet
became difficult to be tilled.
• Covers near by 16 % geographical area India’s .
Red & Yellow Soil
• Covers about 10.6 % of India’s geographical
area.
• Red colour of soil is due to diffusion of iron
particles into crystalline and metamorphic
rocks.
• Where it is founded hydrated it turns to
Yellow.
Laterite soil
• Covers about 7.2% of India’s geographical
area.
• Low humus content .
• Very useful for coffee and tea plantation .
• Can be made cultivable by adding manure and
fertilizers.
Forest or Mountain Soil
• They are loamy and silty in valley side and
coarse grained in the upper slopes.
• Low humus content and acidic in north
side(J&K region).
• Used for cultivating spices , tea and coffee.
Arid soil
• Lacks in humus and moisture due to dry
climatic conditions and high temperature
where it is found.
• Kankar are found in it .
• After proper irrigation , these soil become
cultivable .
Soil Erosion
• Soil erosion is the washing or blowing away
(by wind or water) of the top layer
of soil (dirt).
• This is a serious problem for people who want
to grow crops. Crops are the foods
that farmers grow. If the soil has eroded, the
crops will not grow very well.
Soil Conservation
• Soil erosion can be conserved in several ways.
• Aforestation
• Terrace farming
• Planting wind breakers (the plants in row).
