What are four ways to prevent or reduce erosion?

Answer 1

The best way to prevent soil erosion is to plant the kind of plants that have dense, fibrous root systems that will keep the soil in place, and the kind of plants that are going to be growing every year without replanting. Namely, grasses and forbs.

Trees are nice, except that it takes years for them to grow into saplings from just a rooted stick stuck in the ground, and you're still going to have a lot of bare soil exposed in such an area. Weeding is necessary so that the trees can grow, and this still is promoting soil erosion. Any soil that can blow or wash away from a gust of wind or heavy rain is soil that is eroding. That's why having perennial grasses and forbs in the ground first are best before allowing the woody plants (trees and shrubs) to come in.

Logging itself isn't going to promote more soil erosion. This is probably something you don't want to hear, but it's true. In most forests and in many deforested areas, once the trees are gone the undergrowth quickly takes over, and those are predominantly grasses and forbs. These plants are Nature's way of assuring that soil erosion is minimized and that soil remains covered despite the extreme reduction in canopy cover.

Planting or seeding grasses and forbs that are native to the area are recommended, however some exceptions may be necessary especially if what already commonly grows in the area is also best to plant (with some exceptions such as noxious or notable invasive species that are encouraged to not be planted and encouraged propagation). Allow the plants to grow and propagate themselves for an entire year without any mowing or grazing. Mow only if weeds have taken over the area, and only once for the year. This is because once the weeds have been cut, the grasses will soon take over, and quite quickly.

Grazing is recommended, but in a controlled and highly managed manner. Graze so that half the plant matter is kept and half is taken so that litter is still available for good soil cover, but so that the animals are leaving enough manure behind for nutrients for the plants. Do not graze when the plants are less than a foot tall, and know your optimum stocking rate or density is for the area. Controlling movements mean moving from one paddock to another regularly depending on the growth of the plants and the amount of forage available. Allow for significant rest periods, and if possible, consider leaving some pastures or areas ungrazed until the fall when plants have completed their life cycles.

If grazing is not an option, mowing on occasion is a good alternative as well. However mowing doesn't do as good a job of controlling the amount of litter accumulated from the growth-death cycles of perennial plants as grazing/browsing animals do.

So five ways to prevent soil erosion and to conserve soil are:

1) Plant grasses and forbs

2) Keep a permanent vegetative cover over soil all year-round for many, many years

3) Manage and maintain the vegetative cover using grazing animals

4) Control and manage grazing animals to maintain vegetative cover and encourage increase in soil organic matter, carbon sequestration and the establishment of new plants for a more biodiverse grassland or even savannah-type ecosystem

Answer 2

Two main ways to control soil erosion are:

• Stop Deforestation
• Plant more trees

Trees and plants are the main things that hold on to the soil and stop it from being eroded away. The more vegetation we have the lesser the erosion would be.

Other ways are by installing terracing, contour plowing, planting grassy filter strips (particularly in riparian areas), intercropping, planting cover srops, and installing soil "stops" (bales of hay and/or straw placed in a washout to stop further erosion).

Answer 3

SOLUTIONS :-

1. to prevent erosion of bare soil, it is important to maintain a vegetation cover, especially in the most vulnerable areas e.g. those with steep slopes, a dry season or periods of very heavy rainfall. To do this may mean only partially harvesting forests (e.g. alternate trees) and using seasonally dry or wet areas for pastoral rather than arable agriculture.

2. where intensive cultivation takes place, farmers should use a crop rotation in order to prevent the soil becoming exhausted.

Where soils are ploughed in vulnerable areas, contour ploughing (i.e. round the hillside rather than down the hillside) should be used.

Careful management of irrigation, to prevent the application of too much or too little water, should help reduce the problem of salination.

3. livestock grazing rates must be carefully managed to prevent overgrazing.

4. perhaps we must attempt to restrict highway construction and urbanisation to areas of lower agricultural potential. With extractive industries, a pledge must be secured to restore the land to its former condition before planning permission for quarries or mines is granted.

Answer 4

• Managed grazing permanent pastures instead of cropping.
• Maintain buffer zones of riparian areas.
• Don't clear land for any building or cropping or anything.
• Let land go back to natural state.

Realistically, though, there is no such thing as no erosion. No matter what humans do, there's always going to be some level of natural erosion occurring no matter where. The Rocky Mountains are slowly eroding away, and we can't prevent that from happening. People are always clearing land for new development, and there's no stopping that either.

Answer 5

Soil erosion can be prevented by forests,by control of grazing and by providing proper drainage system in the fields.

Answer 6

allow water percolation plantation avoid water drift or flush over land allow water percolation plantation avoid water drift or flush over land

Answer 7

1. plant more trees

2. stop illegal logging

3. report illegal loggers to authorities

4. stop irresponsible mining

5. conserve soil and go green
