  • What are the disadvantages of shifting cultivation?

    Q: What are the disadvantages of shifting cultivation?

    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.

  • How do farm silos work?

    Q: How do farm silos work?

    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.

    Q: What is the definition of sedentary farming?

    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.

  • How is cotton picked?

    Q: How is cotton picked?

    A: Large exporters of raw cotton, such as the United States, Australia and Europe, mechanically pick and harvest cotton through stripper and spindle pickers.

  • What are the advantages and disadvantages of agriculture?

    Q: What are the advantages and disadvantages of agriculture?

    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.

  • What is conventional farming?

    Q: What is conventional farming?

    A: Conventional farming is a term used to designate farming techniques that are traditionally, and often controversially, oriented towards using technology, pesticides, chemicals and other synthetic tools in the cultivation of crops. Thus "conventional" is often used as an antonym for "organic," a farming approach that alternatively seeks to limit or eradicate the introduction of synthetic elements into agriculture.
