How contour plowing prevent soil erosion?

Answer 1

It slows the water from rain as it comes down the terraced area, thus preventing erosion.

Terracing helps to prevent erosion because it slows rain water as it runs down the terraced area.

Answer 2

Because the strong roots of the trees and plants holds the soil and preventing it from being very soft. Also the roots of the trees and plants drink water from the soil which lessen the probability to have floods.

Answer 3

Plant a diverse selection of plants on your landscape

Encourage rich soil with organic matter that works as a glue for the soil

Block water paths with stone or wooden retaining walls.

Plan and encourage proper drainage.

Follow lawn and garden care guidelines to promote healthy plants.

Planting Vegetation

One of the most common ways to prevent soil erosion on residential landscaped gardens and vegetation and crop properties is to plant flowers, trees and crops over the affect soil. Plants act as protective shields to the soil lessening the impact of rainfall, wind, excessive watering and ice melt. The plants will also help stabilize the soil and prevent it from becoming prone to soil erosion. Some popular soil erosion prevention plants are: wild flowers, crop veggies, small trees and herbs. Plants which crawl up and spread instead of growing upwards are also great soil erosion prevention plants.

MattingSoil erosion prevention products are available in many styles. One of the most common products which are most commonly used on residential properties, vegetation crops and vacant land is matting. Matting is available in wood fibres which make it environmentally friendly and biodegradable. The matting will be placed on the soils surface and prevent erosion from occurring. The matting will allow plants, crops and trees to grow through it and the soil will be healthy and stabilized. Matting can be cut to size to suit your property.

Mulch/FertilizerAnother soil erosion prevention method which is beneficial to the soil and plants which live in it, is applying a layer of mulch and fertilizer over the soil. The mulch and fertilizer layer will assist the soil to soak in water slowly and it will also lessen the impact of rainfall as it penetrates through to the soil. The mulch and fertilizer layer will also stabilize the affect soil by regaining its PH levels to be healthy and neutralized. Any type of mulch or fertilizer can be used to prevent soil erosion.

Retaining Walls/EdgingWet patches or mud puddles on your driveway, or any hardscaped area are a sign of soil erosion runoff. This is generally caused by water erosion. Water erosion is affecting the soil and making it expand and travel to different areas of the yard such as the driveway. You can prevent this from occurring by building a small retaining wall around your garden beds. The retaining wall will act as a shield for the soil and prevent soil erosion from occurring. The wall will also keep water retained in the garden bed so that the soil will slowly soak it in. if used in conjunction with other soil erosion prevention methods this method can be very rewarding to your property.

They include planting of young trees to replace those cut down. Farming methods that promote soil conservation include crop rotation, contour planting, and soil-drainage systems. The building of dams helps to collect excess water and prevents it from flooding the land.

Checking of overgrazing and stopping the cutting down of forests.

Terracing of sloping lands reduces the speed of water and prevents soil erosion.

Bunds around the fields checks the erosion of the soil.

Irrigation channels around the fields should be designed to carry water at a slow speed and fast flowing water tends to carry away the topsoil.

Intensive cropping prevents soil erosion.

Contour ploughing checks soil erosion by water.

Drainage canals prevent soil erosion.

You can prevent by planting things and if you have a house on the property you can have a retaining wall all around it.

Contour farming -- furrows made with a plow follow the contour of the land. Each furrow serves as a dam, preventing the water from easily sinking into the soil.

A:

We can stop soil erosion by planting more trees to anchor the soil to the ground. Also we can go nomadic again so we are not overfarming or overgrazing in one place. Furthermore, if you have animals move them around every day.

A:

The first and most important is to keep the soil covered with some type of vegetation. Erosion begins when a rain droplet strikes the exposed soil and detaches a particle of sol so that it can be washed away by runoff water. Decreasing the length of the slope so that the water can't gain energy through gravity and so carry soil with it is another way. A third is by increasing the amount of organic matter in the soil itself. Organic matter helps to bind the soil together so that rain has a harder time detaching the particle in the first place.

A:

The impact of wind and water erosion on agricultural land and the surrounding environment can be reduced by:

Preserving the condition of the soil surface by modifying farming practices, for example using conservation tillage techniques which do not disturb the soil as much as traditional tillage techniques and preventing stock from trampling the soil

Keeping vegetation cover on the soil surface at all times, by adjusting stocking rates to prevent overgrazing, keeping crop stubble in place after harvesting and avoiding clear felling of forests

Installing natural or artificial windbreaks, which reduce the speed and damaging effects of the wind can also reduce the environmental impacts of wind erosion.

How can the soil be improved?

Support organic farming by purchasing organic foods and encourage your local retailer to stock organic produce.

If you are a farmer, you can conserve your soil resources by using conservation tillage techniques to reduce soil disturbance and compaction and by reducing stocking rates to limit soil compaction.

However,the best way to reduce soil erosion is by making sure the soil is covered by vegetation as much as possible. You can achieve this by revegetating areas of your farm with native trees and understorey plants,leaving crop stubble in place after harvesting and by including cover crops or pasture in your cropping rotations.

by reducing deforestation and by planting more trees.
Vegetation with a complex root system, like grass, does a good job at minimizing soil erosion.

Answer 4

Plowing a hillside field straight up and down, from top to bottom, provides channels for rainwater to flow, unimpeded. This will strip the topsoil off in a few years, making the land worthless. Plowing the other way, along the hill, slows the water flow, and lets it soak in more, instead of picking up speed and gullying the slope.

Answer 5

The roots hold the soil causing less soil getting out.The roots of the trees are all connected and wash the soil to make it fertile so it doesn't move

Answer 6

The water gets partly sucked up by the plants, instead of going- WHOOSH- this year's harvest destroyed, boohoo.

Answer 7

Terracing reduces landslides by supporting the the soil, that is a series of short walls horisontally placed on a hillside, reduces the down hill trend of soil caused by erosion and gravity.

Answer 8

The root system of the plant can help hold dirt together when it would normally be washed away by rain or blown away by the wind
