Why are farming practices like terraced fields important in terms of soil conservation?
They remove pollutants from the soil, which is essential because living things depend on pollutant-free soil.
They cause nutrients in the soil to leak out, which is essential because plants need nutrient-poor soil.
They help limit the amount of soil that is produced, which is essential because soil is a renewable resource.
They prevent soil from eroding and becoming lost, which is essential because soil is a nonrenewable resource.
so which is the correct answer?
Why are farming practices like terraced fields important in terms of soil conservation?
1. They help limit the amount of soil that is produced, which is essential because soil is a renewable source.
2. They prevent soil from eroding and becoming lost, which is essential because soil is a nonrenewable source.
3. They cause nutrients in the soil to leak out, which is essential because living plants need nutrients- poor soil
4. They remove pollutants form the soil. which is essential because living things depend on pollutant- free soil
The correct answer is: They prevent soil from eroding and becoming lost, which is essential because soil is a nonrenewable resource.
Terraced fields are an important farming practice when it comes to soil conservation. They involve creating level or nearly level areas, with a series of terraces or platforms that are built into the landscape. Here's why they are important:
1. Preventing soil erosion: One of the key benefits of terraced fields is their ability to prevent soil erosion. By constructing terraces, the slope of the land is divided into smaller, more manageable sections. The terraces act as barriers that slow down the flow of water, reducing its energy and preventing it from washing away the topsoil. This is crucial because erosion can deplete the fertile top layer of the soil, which is essential for productive farming.
2. Controlling water runoff: Terraced fields also help in controlling water runoff. By trapping rainwater within each terrace, they allow it to infiltrate into the ground slowly. This helps in recharging groundwater and prevents excessive runoff, which can lead to soil erosion and loss.
3. Conserving fertile soil: Soil is a nonrenewable resource, meaning it takes thousands of years to form. The topsoil, in particular, is rich in organic matter and nutrients needed for plant growth. Terraces help to conserve this fertile topsoil by preventing it from being washed away and lost.
4. Enhancing nutrient retention: Terraced fields can also aid in maintaining nutrient levels in the soil. Nutrients are often concentrated in the top layer of soil. By preventing erosion and water runoff, terraces help to retain these nutrients within each terrace, making them available for plant uptake.
In conclusion, farming practices like terraced fields are important for soil conservation because they prevent soil erosion, conserve fertile soil, control water runoff, and help retain nutrients. Ultimately, this promotes sustainable agriculture and ensures the availability of nutrient-rich soil for future generations.
