According to the US Geological Survey, furrow irrigation is a form of surface irrigation where trenches are used to deliver water to rows of crops. Most modern farming operations replaced this method with mechanized spray irrigation systems.
A:Large exporters of raw cotton, such as the United States, Australia and Europe, mechanically pick and harvest cotton through stripper and spindle pickers. A stripper picker removes the entire cotton boll off the plant along with other unopened bolls. The spindle cotton picker, on the other hand, removes the cotton from the boll and leaves the plant intact.
A:Agricultural silos work by creating a pressurized area within a cylindrical container that helps to keep fodder and hay that is used to feed farm animals free from spoilage. There are several different types of silos that vary slightly in design but operate in the same manner to keep animal food from rotting. Most silos exist as upright cylinders that are constructed with sturdy materials such as porcelain or steel that help to prevent corrosion.
A:Polyculture is the practice of growing multiple crops in one specific area of land, while monoculture means that an area of land only grows a single crop. A garden is an example of polyculture, and a cornfield is an example of monoculture.
A:A combine harvester is a machine used to harvest grains like wheat, rye, barley, oats, corn, flax and soybeans. Instead of using separate machines for reaping, threshing and winnowing the grain, the harvester combines all these functions into one machine.
A:Farm mechanization refers to the development and use of machines that can take the place of human and animal power in agricultural processes. The mechanization of agriculture that took place during the 20th century led to major changes in how farmers plant, irrigate and harvest crops. Combines, tractors, harvesters and other machinery have enabled farmers to increase their production while relying less upon an extended labor force.
A:Farming is important because it provides food and jobs in a society. Industrial farming provides a large amount of food for a relatively low cost. Family farming improves the local land and reduces the family's dependency on commercially grown food and grocery stores.
A:Hay and silage are the forms in which harvested forage is most often stored. The two differ in terms of how they are stored and their moisture content. While hay is stored at a moisture level below 20 percent, silage is stored at 40 to 60 percent moisture level. When hay is stored at moisture levels greater than 20 percent, the forage becomes moldy and may suddenly catch fire.
A:Sedentary farming is a method of agriculture in which the same land is farmed every year. This is in contrast to nomadic farming, in which new areas are farmed as the soil becomes less nutrient-rich from extensive planting, and shifting cultivation, which uses controlled forest fires to produce arable land.
A:According to the US Geological Survey, furrow irrigation is a form of surface irrigation where trenches are used to deliver water to rows of crops. Most modern farming operations replaced this method with mechanized spray irrigation systems.
A:According to WebMD, possible disadvantages of genetically modified crops include environmental hazards such as the creation of herbicide-resistant weeds, altering the nutritional content of food, resistance of crops to antibiotics, the presence of toxins and allergens and the risk of contamination between modified and unmodified crops.
A:Celery can be grown in all the states of the United States except Alaska and Hawaii, according to the Old Farmer's Almanac. Because extreme heat and extreme cold prohibit the growth of this long-season crop, these states are excluded. Celery is grown in USDA growing zones 2 though 10; however, planting time varies considerably based on the location it is being grown.
A:Shifting cultivation, also known as slash and burn agriculture, is an agricultural system that involves clearing a section of land and using it for farming activities for a relatively short time before abandoning it. Farmers then typically shift their agricultural operations to a new section of freshly cleared land.
A:Modern agriculture has vastly increased the amount of food that farms are capable of producing with great gains in efficiency, but it can also have a major negative impact on the environment. Large-scale farms are vital for keeping the world fed, but they can devastate local ecosystems through clearcutting and runoff, which often releases methane, ammonia and other toxic chemicals into the environment.
A:Traditional agriculture is a type of farming that uses techniques developed over decades or centuries to ensure good, sustainable yield over time in a specific area or region. Traditional farms are based around mixed crops that complement one another.
A:Cotton is harvested beginning in July in the southern part of Texas through late November in northern parts of the United States. Machines with turning rods are used to harvest cotton, which is dropped onto conveyor belts after having seeds removed. Rolling machines further process the cotton before it is packed into bales, which weigh about 500 pounds and are stored in trailers.
A:The best climate for growing rice is one that is warm and moist according to the United Nations University. Although rice requires a lot of water, rice does not grow well in very lush wet climates or waterlogged areas. That said, rice can be cultivated in a wide range of environments.
A:The primary disadvantage of shifting cultivation, also called slash and burn or swidden agriculture, is the destruction of large areas of land, primarily crop fields and tracts of forest. When performed improperly, slash and burn can make once-fertile lands unable to support the new growth of crops and plants. Slash and burn may cause environmental and economic consequences by reducing the growth potential for crops in certain areas, which limits the variety and quantity of agricultural goods farmers can produce.
