Concept
Monoculture
Summary
In agriculture, monoculture is the practice of growing one crop species in a field at a time. Monoculture is widely used in intensive farming and in organic farming: both a 1,000-hectare cornfield and a 10-ha field of organic kale are monocultures. Monoculture of crops has allowed farmers to increase efficiency in planting, managing, and harvesting, mainly by facilitating the use of machinery in these operations, but monocultures can also increase the risk of diseases or pest outbreaks. Diversity can be added both in time, as with a crop rotation or sequence, or in space, with a polyculture or intercropping (see table below).
Continuous monoculture, or monocropping, where farmers raise the same species year after year, can lead to the quicker buildup and spread of pests and diseases in a susceptible crop.
The term "oligoculture" has been used to describe a crop rotation of just a few crops, as practiced in several regions of the world.
The concept of monoculture can also extend to (for example) discussions of variety in urban landscapes.
In an agricultural context, the term describes the practice of planting one species in a field. Examples of monoculture include lawns, fields of wheat or corn, or an apple orchard.
Note that the distinction between monoculture and polyculture is not the same as between monocropping and intercropping. The first two describe diversity in space, as does intercropping. Monocropping and crop rotation describe diversity over time.
In crop monocultures, each plant in a field has the same standardized planting, maintenance, and harvesting requirements resulting in greater yields and lower costs. When a crop is matched to its well-managed environment, a monoculture can produce higher yields than a polyculture. Modern practices such as monoculture planting and the use of synthesized fertilizers have reduced the amount of additional land needed to produce food, called land sparing.
