Agroforestry: Field‐and‐Interstitial Support Trees
In this type of agroforestry, trees in groves or rows are separated spatially from crops, but are in a common field with them. The trees may be planted in arrangements interstitial (with small openings or gaps) to crop fields, for example, as field borders, or along the contours of a slope. In a variation, the trees and crops may be rotated in a field. In this agroforestry rotation, the trees interplanted in a mixture with crops may be cut back (coppiced) to allow crops to grow in the sun, and in a later phase allowed to take over and dominate the field for a period when their products are needed. This last essentially entails a rotation or alternation – or “separation” – of trees and crops through time. In all variations, the trees support the crops, as well as yield products of their own.
