Sedges on the edge: new agronomic and research opportunities?

Abstract Background The paper by Tan and co-authors in this issue of Plant Soil explores feedback mechanisms between functional traits soil nutrient responses tiger nut ( Cyperus esculentus L.), with emphasis on their growth marginal agricultural lands. Scope Many the world’s top food species belong to order Poales, specifically family Poaceae. Cyperaceae, also are recognised for ecological importance, yet currently provide only minor contributions global security. Conclusions Wide tolerance naturally weedy tendencies may a unique niche significant increase production nuts as resource. Further research ecology agronomic potential Cyperaceae is advocated.
