Answer 2

Conservation

Question 3

What are the different topics involved in the study of land and water management engineering?

Answer 3

• Soil Erosion Control
• Moisture Conservation
• Land Development
• Irrigation
• Groundwater Development and Wells
• Agricultural Drainage
• Watershed Management

Question 4

This refers to the protection of soil from erosive action of natural agencies like water and wind,

Answer 4

Soil erosion control

Question 5

These are practices needed to conserve rainfall for crop protection.

Answer 5

Moisture conservation

Question 6

This refers to reclaiming land from conditions that make the land unsuitable for cultivation. It is also referred to as land grading which is making the land suitable for irrigation.

Answer 6

Land development

Question 7

This deals with the exploitation of underground water resources.

Answer 7

Groundwater development and wells

Question 8

It is the artificial application of water to land for crop production.

Answer 8

Irrigation

Question 9

This refers to the removal of excess water that is not needed or otherwise harmful to crop growth.

Answer 9

Drainage

Question 10

This refers to a combination of practices to achieve objectives like a reduction in floods or the sediment outflow from an area. Another emerging area with which land and water management is concerned is environmental management.

Answer 10

Watershed management

Question 11

These are major components of the environment, and protecting land and water quality is part of land and water management.

Answer 11

Land and Water

Question 12

This helps in reclaiming waterlogged or salt-affected conditions

Answer 12

Agricultural Drainage

Question 13

This practice consists of prevention and control of soil erosion caused due to wind and water.

Answer 13

Soil and water conservation

Question 14

What are the factors needed for obtaining maximum agricultural production.

Answer 14

• Proper land preparation
• Use of Improved Seeds
• Use of Optimum Dosage of Fertilizers
• Efficient Water Application
• Insect & Pest Control

Question 15
