20 Examples of Polycultures

Systems polycultures they are a type of farming which consists of growing different species from plants on the same land area, in such close proximity that the advantages of these simultaneous crops are perceived. For example: onion with tomato, garlic with leeks, spinach with cabbage.

Polyculture is a agriculture tool in which annual crops can be complemented with other annuals, annuals with perennials or between perennial crops. In the same way, the components of a polyculture can be sown on the same date or on different dates, with potentially simultaneous harvests or at intervals.

Any simultaneous combination of agricultural processes is considered a polyculture. However, according to the implications in each of the crops, they are classified as follows:

Research in polycultures was deepened from the discovery of many of its advantages.

One of the main reasons that motivate adoption of polycultures is that with them a higher yield is obtained from the sowing area: in places where the conditions socio-economic conditions are subject to the amount of land that can be weed, the advantages of polyculture are obvious.

In another sense, polyculture has a spatial advantage which is that can be quantified in percentage, since what is harvested in one hectare of a polyculture is equal to what can be harvested in the sum of two amounts of hectares of monoculture: in the difference between these values ​​will be the spatial advantage of the polyculture, which can oscillate between 20% and 150%.

The variability in production also has an advantage insofar as it seeks to minimize the risks of losing total harvest: this is one of the reasons why the use of polyculture is more widespread in developing countries. growth.

The choice of a polyculture system, however, cannot be made in any way. Different aspects of agriculture must be taken into account, such as:

Many agricultural engineers are dedicated to studying the effects of polyculture systems on insect pests, plant pathogens, and weeds.
