Answer 1

1 main uses of land resources are: land is used for agriculture. land is used for transportation.

2 . proper land use plan be prepared as follows : we should not use fertilisers for agriculture.

3 . waterlogging saturated water.

4 . gets organic matter by decomposing humus. in

inorganic matter come from weathering of rocks.

5. Well : well is cheapest source of irrigation. well is independent source of irrigation.

Tubewell: it is a most popular system of irrigation in India. it is also cheapest form of of irrigation.

6. measures that can help in soil erosion :

a. we should make dams.

b. we should not cut trees.

7. irrigation potential is increased but not used. poor efficiency of irrigation. poor implementation of irrigation system.

8. crop rotation and mixed cropping improve the fertility of the soil.

9. irrigation facility

flood control

generating electricity

navigation

10. alluvial soil, black cotton soil, laterite soil , red soil.

Answer 2

Answer:

1. There are many types of land use:

• Recreational - fun, non-essentials like parks.
• Transport - roads, railways, and airports.
• Agricultural - farmland.
• Residential - housing.

• Commercial - businesses and factories.

2. Planning steps:

Data and information gathering, review and evaluation, including land information and associated attribute data. Identification of targets, goals and needs catering to development requirements, protection or conservation requirements, and social economic and environmental requirements.

3. Water logging occurs when there is too much water in a plant's root zone, which decreases the oxygen available to roots. Water logging can be a major constraint to plant growth and production and, under certain conditions, will cause plant death.

4. The inorganic components come from the weathering of various rock types. Organic particles are the result of both plants and animals inhabiting the area. While some soil has only one particle type, the most fertile soil is a mixture of several organic and inorganic components.

5. North India has wide spread deposition of alluvial soil which is suitable for well irrigation. In south India ground water reserve is far below the surface but in north India the ground water level is within easy reach. this well irrigation is more important in north India.

6.

• Contour ploughing.
• Terracing.
• Shifting cultivation.
• Crop rotation.

7.  irrigation potential created but not being used; poor efficiency of irrigation systems; indiscriminate use of water in agriculture; poor implementation and maintenance of projects; cropping patterns not aligned to agroclimatic zones; subsidised pricing of water; citizens not getting piped water supply; and contamination of groundwater. These are problems, caused by 72 years of mis-governance in the water sector, and remain challenges for the future.

8. Crop rotation and mixed cropping improve the fertility of the soil. It would increase production which can sustain large population. 3. Desertification can be checked by artificial bunds or covering the area with proper type of vegetation.

9. Contrasted to a single-purpose project that serves only one purpose, a multipurpose project is designed for irrigation, power, flood control, municipal and industrial, recreation, and fish and wildlife benefits, in any combinations of two or more.

10. Major groups:

• Alluvial soils,
• Black soils,
• Red soils,
• Laterite and Lateritic soils,
• Forest and Mountain soils,
• Arid and Desert soils,
• Saline and Alkaline soils and.
• Peaty and Marshy soils.
