Which sustainable agricultural practice involves tilling and planting on ridges that are across or perpendicular to a slope?

Terracing is a soil conservation practice applied to prevent rainfall runoff on sloping land from accumulating and causing serious erosion. Terraces consist of ridges and channels constructed across-the-slope.

What method of farming is used in slope surface?

contour farming, the practice of tilling sloped land along lines of consistent elevation in order to conserve rainwater and to reduce soil losses from surface erosion.

What is contour farming in agriculture?

Description. Contour farming is the practice of tillage, planting, and other farming operations performed on or near the contour of the field slope. This method is most effective on slopes between two (2) and ten (10) percent.

What is contour farming and terracing?

What it is. Contouring means farming with row patterns nearly level around a hill – not up and down hill. The rows form hundreds of small dams that slow water flow and increase infiltration to reduce erosion.

What is conservation tillage farming?

"Conservation tillage—Any tillage and planting system that covers 30 percent or more of the soil surface with crop residue, after planting, to reduce soil erosion by water.

What is conventional and conservation tillage?

Conventional tillage, such as moldboard plowing, leaves the soil surface bare and loosens soil particles, making them susceptible to the erosive forces of wind and water. Conservation tillage practices reduce erosion by protecting the soil surface and allowing water to infiltrate instead of running off.

What is conventional tillage practice?

Conventional tillage is a tillage system using cultivation as the major means of seedbed preparation and weed control. Context: Typically includes a sequence of soil tillage, such as ploughing and harrowing, to produce a fine seedbed, and also the removal of most of the plant residue from the previous crop.

What are contour ridges?

Contour ridges are an in-situ rainwater harvesting technology developed initially for soil erosion control but are currently also widely promoted for rainwater harvesting. The effectiveness of contour ridges depends on geophysical, hydro-climatic and socio economic factors that are highly varied in time and space.

What is contour irrigation?

What Is Contour Furrow Irrigation Method? With contour-furrow irrigation, water is carried across a sloping field rather than down the slope. The furrows have just enough grade to carry the irrigation streams. Head ditches or pipelines are run downhill, or slightly across the slope, to feed the individual furrows.

What are the types of contour farming?

What is the difference between terrace farming and contour farming?

Terrace farming alters the shape of the slope to produce flat areas whereas contour ploughing follows the natural shape of the slope without altering it.

In which region a method of ploughing along the contour lines is usually adopted for soil conservation?

The correct answer is In erosion affected soil areas. Contour farming is the practice of filling sloped land along lines of assistant elevation in order to conserve rainwater and reduce soil erosion. Contour ploughing is practiced generally in slopy areas to prevent soil erosion.

What is contour ploughing in geography?

Contour ploughing is a well-established agronomic measure that contributes to soil and water conservation [25] (see figure 1). The soil is ploughed along the contour instead of up- and downward (see figure).

Which of the following techniques uses plowing across the slope to form ridges?

Contour plowing was a method of plowing furrows that follow the curves of the land rather than straight up and down slopes. Furrows that run up and down a slope form a channel that can quickly carry away seeds and topsoil. Contour plowing forms ridges, slows the water flow and helps save precious topsoil.

Where is contour farming used?

Contour farming is a traditional Pacific Island practice that is very good for growing food on hillsides. When farmers carry out their farming activities (plowing, planting, cultivating, and harvesting) across the slope instead of up and down the slope, they are using contour farming contour farming contour farming.

What do you mean by tillage?

Tillage is defined as the mechanical manipulation of the soil for the purpose of crop production affecting significantly the soil characteristics such as soil water conservation, soil temperature, infiltration and evapotranspiration processes.

What is greenhouse farming?

Greenhouse farming is the agricultural practice of growing crops in sheltered structures covered by a transparent material such as, glass houses, shade houses, screen house and even crop top structures.

What is making ridges across the slope?

When you make ridges across the slope, When you plough across the slope, You are working on the contour line. A contour line is a line across the slope running always at the same height! Making ridges along the contour lines helps to control erosion.

What is ridging across the slope?

One way of achieving that is through contour ridges. These ridges, which can be made of earth or stone, are built across the slope, trapping the rainfall and encouraging it to enter the soil rather than flow down the slope. To be successful, contour ridges must be perfectly level.

How contour ridges reduce soil erosion?

By combining both the land preparation and the planting along the contours, small contour ridges are shaped. These, together with the planted crop, serve as obstacles, causing slight flooding and will thus increase the infiltration of the water into the soil and reduce the erosion (Table 2).

What is secondary tillage?

In agricultural technology: Secondary tillage. Secondary tillage, to improve the seedbed by increased soil pulverization, to conserve moisture through destruction of weeds, and to cut up crop residues, is accomplished by use of various types of harrows, rollers, or pulverizers, and tools for mulching and fallowing.

What are the types of tillage?

Tillage :: Types of Tillage. Depending upon the purpose or necessity, different types of tillage are carried out. They are deep ploughing, subsoiling and year-round tillage.

What are the types of conventional tillage?

Conventional tillage usually consists of primary tillage, or plowing, and secondary tillage, which is normally done by disking with harrows and maybe a third step with spring tooth harrows. If seeding a forage or pasture crop, the soil can finally be firmed with a roller, or cultipacker.

How do conservation tillage practices lead to agricultural sustainability?

Conservation tillage practices naturally protect crops from insect damage, reducing the need for pesticides.

What is conventional ploughing?

Ploughing is a reliable, tried and tested tillage method that works well in most conditions and provides a number of unique advantages. In one pass, the plough produces a straw-free surface and loosened soil in which a seedbed can be created and a new crop established.
