Readers ask: Why Terracing In Farming?

Why do farmers build terraces?

Terraces reduce the rate of runoff and allow soil particles to settle out. The resulting cleaner water is then carried off the field in a non-erosive manner. Terraces are used to reduce sheet and rill erosion and prevent gully development. Grassed frontslopes and backslopes of some terraces provide cover for wildlife.

What are the benefits of terracing?

Terraces reduce slope length, reducing the power of flowing water to erode soil. By limiting soil erosion, terraces also improve water quality by reducing sediment and phosphorus delivered to streams, rivers, and lakes.

Where is terracing used to farm?

Terrace farming is the practice of cutting flat areas out of a hilly or mountainous landscape in order to grow crops. It is a practice that has been in use from the rice fields of Asia to the steep slopes of the Andes in South America.

What is the environmental impact of terrace farming?

Nevertheless, soil erosion and the loss of topsoil are still major threats to terrace farming. Terracing affects the rate of soil erosion caused by water through its effect on local hydrology, runoff characteristics, soil moisture and soil characteristics (Chow et al., 1999).

Is terracing good or bad?

Terracing is one of the oldest means of saving soil and water. Existing literature and information shows that terraces can considerably reduce soil loss due to water erosion if they are well planned, correctly constructed and properly maintained. If not maintained, they can provoke land degradation.

How does terracing help the soil?

On steep slopes, terracing can make planting a garden possible. Terraces prevent erosion by shortening the long slope into a series of shorter, more level steps. This allows heavy rains to soak into the soil rather than run off and cause erosion.

How is terracing done?

Terrace farming is a technique of farming whereby “steps” known as terraces are built onto the slopes of hills and mountains. Whenever it rains, instead of rain carrying away the soil nutrients and plants down the slope, they flow to the next terrace. Every step has an outlet that channels the water to the next step.

What type of farming is called terrace farming?

Terrace farming is a method of farming whereby “steps” known as terraces are built onto the slopes of hills and mountains. When it rains, instead of rain carrying away the soil nutrients and plants down the slope, they flow to the next terrace.

Is tea grown in terrace farming?

Graduated terrace steps are commonly used to farm on hilly or mountainous terrain. Terraced fields decrease both erosion and surface runoff, and may be used to support growing crops that require irrigation, such as rice,and tea.

What is called terrace farming?

Terrace cultivation, method of growing crops on sides of hills or mountains by planting on graduated terraces built into the slope. Though labour-intensive, the method has been employed effectively to maximize arable land area in variable terrains and to reduce soil erosion and water loss.

How expensive is terrace farming?

Terraces do require high capital investments, however. Costs may range from $100 to $250 per acre, depending on the type of terrace system. Terraces are intended to intercept and slow the flow of surface water from unprotected slopes.

How do you build a hillside garden?

The best solution for hillsides is to plant your vegetables across the slope using contour rows, terraces, or raised beds. This not only makes it easier for you but also prevents problems with erosion. Also, take advantage of microclimates when placing crops.

How many types of terraces are there?

There are three kinds of terraces (a) bench terraced farmlands; (b) sloping terraced farmland; (c) combination level terraced farmlands and natural slope land. Bench terrace is the basic type of farmland in mountains. A bench terrace with its level platform and projected or ridged rim may hold rainwater for irrigation.
