Which farming practices reduce soil erosion?
Farming methods that can reduce soil erosion include terracing, contour cropping, windbreaks, and no-till planting.
Which of the following is a method used to prevent soil erosion?
Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion. Conservation tillage methods such as no-till planting, strip rotary tillage, chiseling, and disking leave more of the field surface covered with crop residue that protects the soil from eroding forces.
What is terrace farming?
Terrace farming is the process of cultivating crops on the sides of hills or mountains by planting on graduated terraces carved into the slope, or in other words, the practice of carving flat regions out of hilly or mountainous terrain to produce crops.
Why do farmers leave stalks of harvested plant in the field after the harvesting is over?
Quite often, the crop is left standing in the field long after the cobs have matured, so that the cobs may lose moisture and store more safely after harvest.
Why do farmers leave corn stalks?
The waste leftover from corn harvest is the stalk left behind standing in the field. Leaving the leftover stalks replenishes the soil with much needed organic material as well as serving as a cover crop preventing soil erosion during the harsh winter months.
Which of the following farming practices help to prevent the erosion of topsoil?
Strip cropping: Cultivation in which different crops are sown in alternate strips to prevent soil erosion.
How do farmers prevent wind erosion of topsoil?
Crop rotations using high residue crops (corn, hay, and small grain) produce large amounts of residue that help control erosion. No till planting reduces erosion by keeping more resi- due on the soil and less soil disturbance.
Which of the following is the best method for preventing soil erosion in an agricultural area?
Interplanting of two different crops that mature at different times allows the soil to never be exposed to erosion. Contour plowing across a hill protects soil from water erosion.
What is the another name of terrace farming?
step farming Terrace farming (also called step farming) is a method of farming that consists of different "steps" or terraces that were developed in various places around the world. The Rice Terraces of the Philippine Cordilleras (hills and mountains) is a World Heritage Site.
What is alley cropping in agriculture?
Alley cropping is an agroforestry practice that places trees within agricultural cropland systems. This system is sometimes called intercropping, especially in tropical areas. It is especially attractive to producers interested in growing multiple crops on the same acreage to improve whole-farm yield.
What is harvest threshing?
(i) Harvesting : gathering of a crop is known as harvesting. (ii) Threshing : separate of grain like corn or other crop, typically by flaid. (iii) Winnowing : blow of current of air through grain in order to remove chaff.
What do you do with corn stalks after harvesting?
To keep your garden soil healthy and disease-free in 2015, I suggest cleaning up all the cornstalks as soon as the harvest is over. You can roto-till the cornstalks into the soil as additional organic matter, or, if you prefer, shred them. Roto-tilling the stalks will normally take two passes a few weeks apart.
What do they do with ground corn stalks?
When corn stover is harvested intact (as opposed to the whole plant being chopped for silage, or the stover being left in the field by a combine), it can be cut and gathered by corn binders, which are reaper-binders designed specifically for maize. It can also be baled into large round bales.
What is contour plowing?
Contour plowing follows the contours of hills and slopes, rather than orienting crop rows up and down a slope. It is a technique that was popularized during the New Deal and afterwards in response to soil erosion.
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.
How can soil conservation practices minimize soil erosion?
Cover Cropping and Mulching are effective at reducing soil erosion by leaving a cover over the soil which reduces soil displacement associated with the impact of raindrops hitting soil particles. They also reduce the volume and velocity of runoff over the soil.
What method best helps to prevent wind erosion?
The best way to reduce wind erosion is to keep the wind off the soil surface by covering the soil surface. Growing vegetation, either cash crops or cover crops, protects the soil and keeps the winds higher off the surface. Standing crop residues function the same way.
Why terrace farming is also called as step farming?
In hills, step farming, also known as terrace farming, is prevalent to protect the soil from water current flow on the slopes. It's basically a farming practice that incorporates a series of steps on the slopes known as terraces or steps. The fundamental benefit of terrace farming is that it conserves soil and water.
What do you mean by terrace?
Definition of terrace (Entry 1 of 2) 1a : a relatively level paved or planted area adjoining a building. b : a colonnaded porch or promenade. c : a flat roof or open platform.
What is forage alley cropping?
Alley cropping is the cultivation of food, forage or specialty crops between rows of trees. It is a larger version of intercropping or companion planting conducted over a longer time scale.
What is ley cropping?
: the growing of grass or legumes in rotation with grain or tilled crops as a soil conservation measure.
What is called threshing?
Threshing is the process of loosening the edible part of grain (or other crop) from the straw to which it is attached. It is the step in grain preparation after reaping.
What is called winnowing?
Winnowing is the method in which heavier components of the mixture are separated from the lighter substances with the help of wind. This method is used for separating grains from husk after the process of threshing. Threshing is the process of separating grain from the chaff.
What are corn stalks called?
Corn stover is made up of the stalk, leaves, husks and tassels left in the field after harvesting the grain with a combine.
What is land contouring?
Contouring is preparing the soil, plant- ing and cultivating crops around a hill rather than up and down the hill. Con- tour rows run around a slope nearly on the level. The rows form hundreds of small dams to slow runoff.
What is another name for contour plowing?
Contour bunding or contour farming or Contour ploughing is the farming practice of plowing and/or planting across a slope following its elevation contour lines.
What is soil tillage practice?
Tillage—turning the soil to control for weeds and pests and to prepare for seeding—has long been part of crop farming. However, intensive soil tillage can increase the likelihood of soil erosion, nutrient runoff into nearby waterways, and the release of greenhouse gases into the atmosphere.
What is another name for tillage?
In this page you can discover 12 synonyms, antonyms, idiomatic expressions, and related words for tillage, like: cultivated land, plowland, ploughland, tilled land, tilth, no-till, arable, reseeding, husbandry, cultivation and soil-conservation.
What is soil conservation practices?
Soil conservation practices are those farming operations and management strategies conducted with the goal to control soil erosion by preventing or limiting soil particle detachment and transport in water or air.
