Examples of sequential planting systems include: (a) Planting long-term timber trees into pasture, coffee, or orchards (some of these systems are sequential; others are designed to be stable over time); (b) Planting orchard trees into pineapple fields or annual gardens, and (c) Cultivating annual or short-term crops under forestry plantings until the forest canopy closes (also known as the Taungya system).crops planted together should not have harmful effects on one another, and rooting habits should be understood so plants are compatible and not overly competitive for nutrients and space in the short-term. Planning should also determine how long the short-term crop can be expected to bear until the long-term crop takes over by shading or root competition.
