Abstract
Background and aims: Woody perennials can be difficult to establish on harsh soils in arid and semi-arid regions. Historically, technological advances have focussed on methods to improve transplanting and direct-seeding but the available information on these advances remains fragmented and the edaphic factors have been largely ignored. This review explores the literature on plant establishment and identifies soil properties that limit plant response in harsh environments.
Conclusions: We reveal that some woody perennials are particularly well-adapted to dry conditions and can also help reclaim degraded landscapes. Furthermore, the environmental and phenological factors that limit the success of direct seeding are well understood but the edaphic factors are not. For example, seedbed preparation and subsoil amelioration before seeding have not been evaluated in dry regions. Seed-priming and seed-placement are also poorly understood, as is the tolerance of woody perennials to different salt types in waterlogged soils of extreme pH and high soil strength. The reason why woody perennials can penetrate strong, hard soils is not obvious from the literature. They apparently cannot exert root growth pressures of the same magnitude as domesticated plants, so they must be able to exploit soil biopores and cracks more efficiently. Other gaps in our understanding of the soil factors that limit woody perennial establishment on hostile soils are identified.
