Grow cover crops
would be most beneficial to soil conservation. This answer has been confirmed as correct and helpful.
What plays an important role in soil conservation?
Provide a cover to the soil
.
Bare soil is susceptible to wind and water erosion. Cover crops help protect soil from erosion and helps to build soil organic matter when cash crops are not actively growing. Cover crops can also supply plant nutrients, regulate soil temperature, improve soil structure, and suppress weeds.
What will help in soil conservation?
- Forest Protection. The natural forest cover in many areas has been decreased due to commercial activity. …
- Buffer Strips. …
- No-Till Farming. …
- Fewer Concrete Surfaces. …
- Plant Windbreak Areas. …
- Terrace Planting. …
- Plant Trees to Secure Topsoil. …
- Crop Rotation.
Which of the following human activities may make soils more prone to erosion?
Aside from desertification, there is no doubt that human activities are a major cause of soil erosion in general.
Construction of roads and buildings, logging, mining, and agricultural production
have resulted in large amounts of soil erosion in the U.S. and around the world.
What human activities are responsible for soil erosion happening at advanced rates?
Ploughing, unsuitable agricultural practices, combined with deforestation and overgrazing
, are the main causes of human-induced soil erosion (7, 8).
Why do we need to conserve and protect the soil?
Soil conservation is key to environmental sustainability: It
helps protect natural resources and watersheds
, restores habitats for plants and wildlife, improves water quality, and makes soil healthier. Soil conservation also creates economic opportunity.
What are 3 methods of soil conservation?
- Following methods are normally adopted for conserving soil:
- Afforestation: …
- Checking Overgrazing: …
- Constructing Dams: …
- Changing Agricultural Practices: …
- (i) Crop Rotation: …
- (ii) Strip Cropping: …
- (iii) Use of Early Maturing Varieties:
What are the 4 methods of soil conservation?
- Conservation Tillage. …
- Contour Farming. …
- Strip Cropping. …
- Windbreaks. …
- Crop Rotation. …
- Cover Crops. …
- Buffer Strips. …
- Grassed Waterways.
How can we prevent soil erosion?
- Preventing excessive grazing.
- Prevention of deforestation.
- Plantation of trees and plants.
- Mulch matting can be used to reduce erosion on the slopes.
- Put a series of fibre logs to prevent any water or soil from washing away.
Which of the following is used of soil conservation?
Answer: Techniques for improved soil conservation include
crop rotation, cover crops, conservation tillage and planted windbreaks
, affect both erosion and fertility. When plants die, they decay and become part of the soil.
What are 4 ways humans contribute to erosion?
When humans disturb the earth with
construction, gardening, logging and mining activities
the result is a weakening of the topsoil of the earth, which leads to excessive wearing away and erosion.
What are the factors that influence soil erosion?
- RAINFALL: Consistent heavy rains usually causes erosion of soil at a faster rate. …
- TOPOGRAPHY: It refers to the extent to which a land slopes. …
- PRESENCE OF ORGANIC MATTER IN SOIL: …
- HUMAN ACTIVITIES: …
- OVERGRAZING: …
- DEFORESTATION:
How do human activities affects the rate of erosion?
Humans affect erosion rates in a number of ways across the globe. … Human activities such as
repeatedly walking or biking the same trails or areas
can also contribute to erosion slowly over time. Forest fires also contribute to soil erosion, as vegetation previously holding the soil in place is often destroyed.
How are human activities responsible for soil erosion Class 8?
Soil erosion occurs naturally by wind or harsh climatic conditions but human activities include
overgrazing, overcropping and deforestation
. Overgrazing occurs when farmers stock too many animals such as sheep, cattle or goats on their land.
What is the impact of human activities in soil?
Nonetheless, some human activities have clear direct impacts. These include
land use change, land management, land degradation, soil sealing, and mining
. The intensity of land use also has a great impact on soils.
How do human activities affect the environment?
Humans impact the physical environment in many ways:
overpopulation, pollution, burning fossil fuels, and deforestation
. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
