Maize, beans, and squash form a triad of products, commonly referred to as the "Three Sisters". Growing these three crops together helps to retain nutrients in the soil. Rubber trees and cotton plants were useful for making culturally significant products such as rubber balls for Mesoamerican ball games and textiles, respectively. Evidence of ...
The large squash leaves shaded the soil, preserving moisture and crowding out weeds. The beans fixed nitrogen in the soil and climbed up the corn stalks as support. [19] The Wichita, and possibly other southern peoples, planted or tended thickets of low-growing Chickasaw Plum trees separating and bordering their maize fields. Tobacco was ...
In this austere desert environment, after summer monsoon rains, the Papago would rush to plant tepary beans in small areas where a stream or arroyo had overflowed and the soil was soaked. The tepary bean quickly germinated and matured before the soil dried out. The Indians often managed the flow of floodwater to facilitate the growth of the beans.
Tree farm systems in each state are self-governing and all work under specific guidelines developed by the ATFS's National Operating Committee. The term tree farming was introduced in 1940 by linking the terms in an attempt to make it easier for the public to conceptualize that trees are renewable resources. [20]
The protein from maize is further enhanced by protein contributions from beans and pumpkin seeds, while pumpkin flesh provides large amounts of vitamin A; with the Three Sisters, farmers harvest about the same amount of energy as from maize monoculture, but get more protein yield from the inter-planted bean and pumpkin.

When creating chinampas, in addition to building up masses of land, a drainage system was developed. [6] This drainage system was multi-purposed. A ditch was created to allow for the flow of water and sediments (likely including night soil). [7] Over time, the ditch would slowly accumulate piles of mud. [6]

An example is the Three Sisters, the inter-planting of corn with pole beans and vining squash or pumpkins. In this system, the beans provide nitrogen; the corn provides support for the beans and a "screen" against squash vine borer; the vining squash provides a weed suppressive canopy and a discouragement for corn-hungry raccoons.
