Plant diversity and overyielding: insights from belowground facilitation of intercropping in agriculture
Open accessAbstract
Summary: Despite increasing evidence that plant diversity in experimental systems may enhance ecosystem productivity, the mechanisms causing this overyielding remain debated. Here, we review studies of overyielding observed in agricultural intercropping systems, and show that a potentially important mechanism underlying such facilitation is the ability of some crop species to chemically mobilize otherwise‐unavailable forms of one or more limiting soil nutrients such as phosphorus (P) and micronutrients (iron (F e), zinc (Z n) and manganese (M n)). Phosphorus‐mobilizing crop species improve P nutrition for themselves and neighboring non‐P‐mobilizing species by releasing acid phosphatases, protons and/or carboxylates into the rhizosphere which increases the concentration of soluble inorganic P in soil. Similarly, on calcareous soils with a very low availability of F e and Z n, F e‐ and Z n‐mobilizing species, such as graminaceous monocotyledonous and cluster‐rooted species, benefit themselves, and also reduce F e or Z n deficiency in neighboring species, by releasing chelating substances. Based on this review, we hypothesize that mobilization‐based facilitative interactions may be an unsuspected, but potentially important mechanism enhancing productivity in both natural ecosystems and biodiversity experiments. We discuss cases in which nutrient mobilization might be occurring in natural ecosystems, and suggest that the nutrient mobilization hypothesis merits formal testing in natural ecosystems.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
