what is the difference between crop rotation and shifting cultivation?

Crop rotation gives various benefits to the soil. ... Crop rotation is one component of polyculture. Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, then abandoned and allowed to revert to their natural vegetation while the cultivator moves on to another plot.

Subsistence farming is growing food for your own and your family's direct consumption. Like a backyard vegetable garden, but with fruit, starch crops, and animals as well. Intensive agriculture is anything that really works the land hard. The inputs cost money, so it is generally only done for profit.

"Alternative" agriculture is more loosely defined than is sustainable agriculture, and it generally refers to agricultural practices that are different than those used in conventional Green Revolution style agriculture.

A cash crop is one that can be sold directly to a user for money, such as wheat, corn, sugar, fruits, or whatever foodstuff you're selling to someone. A commercial crop (I've rarely ever seen crops referred to as commercial crops) is one that is sold to a 2nd party who refines it into new products to sell.

Subsistence agriculture is practised on small patches of land with the help of primitive tools like dao, hoe and digging sticks. Commercial farming is done on large scale with the use of huge doses of modern inputs e.g. HYV seeds, chemical fertilizers, insecticides and pesticides.

Rotation of the Earth is its turning on its axis. Revolution is the movement of the Earth around the Sun. ... The Earth's axis of rotation is tilted by 23.5 degrees. This tilt causes the different seasons of the year.

Industrial agriculture is mostly mono cropping with focus on economies of scale, in other words maximizing output while minimizing inputs. Sustainable agriculture on the other hand looks at meeting the human & animal needs for food without compromising the the long-term sustainability of natural resources.

The word Food crops refers to a crop, such as rice or wheat, that is grown for human consumption . In the other hand , cash crops refers to a readily salable crop that is grown and gathered for the market (as vegetables or cotton or tobacco)!!

In the chitemene shifting cultivation system crops are grown in a small ash garden made by burning a pile of wood cleared from a larger area. The burning increased soil NH3–N content by 40–50%, with a further increase of 15% after 262 mm of rainfall. In contrast, the soil in unburnt plots lost up to 30% NH3–N.

Extensive farming is where a relatively small amount of produce is generated from a large area of farmland. Intensive farming is where a large amount of produce is generated from a relatively small area of land. Inputs will be high to achieve a high yield per hectare.

Multiple cropping is raising different crops on separate fields or during different seasons. Mixed cropping is raising different crops in the same field at the same time.

Sustainable agriculture relies solely on natural processes for input and recycles nutrients on-site to eliminate the use of non-renewable resources. Alternatively, conventional agriculture requires an incredible amount of energy to produce, prepare, and transport food.

Because each type of plant needs different types of nutrients. So these nutrients are depleted from the soil. ... So crop rotation will help in giving the soil the needed time and certain bacteria (eg - rhizobium ). so monoculture is bad for soil.

Arithmetic shift is almost same as logical shift but they has some differences. ... Arithmetic shift perform multiplication and division operation, whereas Logical shift perform only multiplication operation. Arithmetic shift is used for signed interpretation, whereas Logical shift is used for unsigned interpretation.

First, organic farming starts with building healthy soil, manage biological activity within the ground and grow healthy plants. Whereas natural farming does not look to build soil biology but to leave the land alone and let processes happen naturally.

However, agriculture is focused on the working of soil and other facilities to produce crops, animals and trees for human consumption or further refinement into products, while industry is focused more on refining and processing raw materials into products for sale.
