Crop Rotation Crop Rotation. Definition - What does Crop Rotation mean? Crop rotation is the systematic planting of different crops in a particular order over several years in the same growing space. This process helps maintain nutrients in the soil, reduce soil erosion, and prevents plant diseases and pests.

Crop rotation Crop rotation. Early agricultural experiments showed the value of crop rotations that included a legume sod crop in the regular sequence. Such a system generally maintains productivity, aids in keeping soil structure favourable, and tends to reduce erosion.

- They move crops from one location to another each year or with each planting season, so that a single type of edible plant is not grown in the same spot season after season. This change of crop location is important for pest/disease inhibition.

Rotation A rotation about an external point, e.g. the Earth about the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity.otation around any axis can be performed by taking a rotation around the x axis, followed by a rotation around the y axis, and followed by a rotation around the z axis. That is to say, any spatial rotation can be decomposed into a combination of principal rotations.

Sustainable Crop Production Sustainable Crop Production. sidebarA. Sustainable crop production is a way of growing or raising food in an ecologically and ethically responsible manner. This includes adhering to agricultural and food production practices that do not harm the environment, that provide fair treatment to workers, and that support and sustain local communities.

Short rotation coppice Short rotation coppice (SRC) is coppice grown as an energy crop.This woody solid biomass can be used in applications such as district heating, electric power generating stations, alone or in combination with other fuels. Currently, the leading countries in area planted for energy generation are Sweden and the UK. plantation can be harvested for up to thirty years before needing to be replanted. When willow or poplar shoots are harvested as whole stems they are easy to store. The stems can be dried for combustion in a pile outdoors; the moisture content of the wood will decrease to about 30% on average until the next autumn.

Center pivot irrigation Center-pivot irrigation (sometimes called central pivot irrigation), also called waterwheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers.t would take hundreds to thousands of years of rainfall to replace the groundwater in the dried up aquifer. In 1950, irrigated cropland covered 250,000 acres. With the use of center-pivot irrigation, nearly three million acres of land were irrigated in Kansas alone.

Rotation A rotation is a circular movement of an object around a center (or point) of rotation . A three-dimensional object always rotates around an imaginary line called a rotation axis. If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin. A rotation about an external point, e.g. the Earth about the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity.

- Rotation refers to movement or spinning around an axis. The Earth rotates around its own axis, which results in day changing to night and back again.The Earth actually revolves around, or orbits, the sun. One revolution around the sun takes the Earth about 365 days, or one year.otation refers to movement or spinning around an axis. The Earth rotates around its own axis, which results in day changing to night and back again.

- solar surface. Solar rotation is one of the principal factors affecting the roughly 11-year cycle of sunspot activity, solar flares, and other phenomena. In the 1860’s Richard Christopher Carrington used sunspots to determine that the period of rotation of the Sun depends on latitude. Spots near the equator of the Sun go around every 25 days, while spots near latitude 45 go around once every 28 days. This so-called differential rotation would not be possible if the Sun were a solid body.

Crop Rotation for Growing Vegetables Planning the Order of Crop Rotation. Brassicas follow legumes: Sow crops such as cabbage, cauliflower and kale on soil previously used for beans and peas. The latter fix nitrogen in the soil, whilst the former benefit from the nutrient-rich conditions thus created.

8 Compelling Reasons to Implement Job Rotation in Your Workplace Job rotation is the structured interchange of workers between different jobs, requiring workers to rotate between different workstations or jobs at certain time intervals. Job rotation increases the variety of tasks required as the worker takes on more duties, enlarging the physical demands and adding variety to the job.

Crop Rotation for Growing Vegetables To avoid these pitfalls, adopt a crop rotation plan. The principle is straightforward enough – the same vegetables should not be planted in the same place year after year. As a system of organic gardening, crop rotation has many advantages: It lessens the need for pest control.

Shifting cultivationupdate Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, then abandoned. This system often involves clearing of a piece of land followed by several years of wood harvesting or farming, until the soil loses fertility.

Shifting agriculture Shifting agriculture, system of cultivation that preserves soil fertility by plot (field) rotation, as distinct from crop rotation. In shifting agriculture a plot of land is cleared and cultivated for a short period of time; then it is abandoned and allowed to revert to its natural vegetation while the cultivator moves on to another plot. The period of cultivation is usually terminated when the soil shows signs of exhaustion or, more commonly, when the field is overrun by weeds.

Tropical agriculture Constantly growing the same crop in the same location will strip the soil of the nutrients that particular crop requires. Rotating to a different crop will reduce the pressure placed on the soil. Or if a green manure is used as part of the rotation sequence, the soil can actually be improved.

Rotation in Geometry A rotation (or turn) is a transformation that turns a line or a shape around a fixed point. This point is called the center of rotation. We usually measure the number of degrees of rotation of a shape in a counterclockwise direction.

Terminology Swidden agriculture, also known as shifting cultivation, refers to a technique of rotational farming in which land is cleared for cultivation (normally by fire) and then left to regenerate after a few years.

Crop Rotation for Growing Vegetables Example of a Four-bed Rotation. Area 1: Enrich area with compost and plant potatoes and tomatoes (Solanaceae). When crop has finished sow onions or leeks (Allium) for an overwinter crop. Area 2: Sow parsnips, carrot, parsley (Umbelliferae). Fill gaps with lettuce and follow with a soil-enriching green manure during winter.

Crop Rotation According to the principles of crop rotation, for example, certain crops, such as flax, should not be planted twice in succession on the same field, and different plants that are attacked by the same diseases should not be sown twice in succession on the same field.

Rotation Relations between rotation axis, plane of orbit and axial tilt (for Earth). Mathematically, a rotation is a rigid body movement which, unlike a translation, keeps a point fixed. This definition applies to rotations within both two and three dimensions (in a plane and in space, respectively.)

Tropical agriculture Crop rotation is the cornerstone pest control in the tropics. When a single crop is planted repeatedly in the same soil, insects and diseases that attack that crop are allowed to build up to unmanageable levels, greatly reducing the farmer's harvest.
