NATURAL RESOURCE

• A material source of wealth, such as timber, fresh water, or a mineral deposit, that occurs in a natural state and has economic value.

EXAMPLE FOR NATURAL RESOURCES:

TYPES OF RESOURCES• BIOTIC :• Biotic describes a living or

once living component of a community; for example organisms, such as plants and animals.

ABIOTIC:In biology and ecology, abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and reproduction. Resources are distinguished as substances or objects in the environment required by one organism and consumed or otherwise made unavailable for use by other organisms .

RESOURCE ON THE BASIS OF EXHASTABILITY :

RESOURCE OWNERSHIP• INDIVIDUAL:Resource which are owned privately by

an individuals. E.g.-car, house & etc. COMMNITY:These resources are accessible for all

the members of the society .E.g.- Public parks , playgrounds & etc.

• NATIONAL: The resource which belongs to the

government .Technically all the resource belonging to the government. E.g.- roads.

INTERNATIONAL: The resource belonging to the

international institutes. E.g.- oceans.

LAND DEGRADATION:• The following are the factors for

land degradation:-• Deforestation• Industrial waste• Overuse of fertilizers• Over grazing of cattle's • Mining.

LAND CONSERVATION:

• By the following ways we could conserve the land resources:-

• A-forestation• Planting shelterbelts• Checking over irrigation• Terrace farming.

SOIL AS A RESOURCES

• Soil is one of the most important natural resource.

• Medium of plant growth and supports different living organism on the earth.

• Takes a million years to form a few cm of soil.

FACTORS EFFECTING FORMATION OF SOIL

• Parent rock• Wind• Climate• Vegetation • Activity of decomposition• Temperature• Glaciers

CLASSIFICATION OF SOILON THE BASIS OF :

• Colour• Texture-age• Chemical and physical properties• Thickness

TYPES OF SOIL• Alluvial soil• Black soil• Red soil or yellow soil• Latterite soil• Arid soil• Forest soil

ALLUVIAL SOIL• Very fertile .• Formed by deposits bought by river• Found in northern plains , coastal

plains, deltas of rivers.• Crops like rice , wheat, cotton , oil

seeds are grown.• Rice in potash and lime.

BLACK SOIL• Black in colour.• This soil is also known as regur soil

,cotton soil , lava soil .• Made up of lava flow. • Good capacity to hold moisture.• Rich in calcium carbonate , lime ,

potash .

RED OR YELLOW SOIL• Found in eastern and southern part

of deccan plateau.• Rich in iron.• Crops like rice , pulse , sugar cane

can be grown.• Porous chores.• Has less content of nitrogen ,

humus , and lime.

LATTERITE SOIL • ACIDIC Porous.• Rich in iron.• Found in eastern ghats and

shillong .• Corps like coffee , rubber and

cashews can be grown.• Leaching by heavy rainfall.

ARID SOIL • Formed by weathering of rocks.• Rich in salt.• Deficiency in humus.• Crops like dates ,melons and bjra

can be grown.• Found in Rajasthan , Gujarat and

Punjab.

FOREST SOI • Found in heavy rainfall areas and

hilly regions .• Acidic in nature.• Deficiency In humus.

SOIL CONSERVATION• CONTOUR PLOUGHING :- ploughing around the contour line

to decelerate the flow of water down the slopes.

Terrance farming :-Cutting down slopes and making

Terrance.

• Stripe cropping :-• Stripe of crops are left to grow b/w

crops . It breaks down the flow of wind.

• Planting shelter belts :-• Planting a line of trees to create

shelter.
