Phosphorus nutrition of phosphorus-sensitive …

 · Many plant species in the south-western Australian biodiversity hotspot are extremely sensitive to P, due to a low capability to down-regulate their phosphate-uptake capacity. Species from the most P-impoverished soils are also very poor competitors at higher P availability, giving way to more competitive species when soil P concentrations are increased.

Phosphorus sensitive plants and fertiliser

 · Examples of phosphorus sensitive plants include members of the Proteaceae family and some Australian native plants such as Banksia, Grevillea and Hakea species. It is important to remember that most Australian species are NOT phosphorus-sensitive and that those that are, still require small amounts of phosphorus to flourish.

What Does Phosphorus Do for Plants? | Hunker

Phosphorus supports the transfer of energy in plants, which is a different role from other plant nutrients, such as nitrogen. Nitrogen is part of the chlorophyll molecule and is needed for vegetative growth, but phosphorus promotes root growth, flowering and setting seed. High levels of phosphorus occur in seeds and fruit, and plants low in ...

 · South-western Australia harbours a global biodiversity hotspot on the world''s most phosphorus (P)-impoverished soils. The greatest biodiversity occurs on the most severely nutrient-impoverished soils, where non-mycorrhizal species are a prominent component of the flora. Mycorrhizal species dominate where soils contain slightly more phosphorus.

Phosphorus Metabolism in Plants

This chapter reviews metabolic processes in which transfer of phosphate occurs in plants. In addition to the chemical energy bound in the components of the cell during growth, some components of all organisms are broken down continuously and must be replaced, a process described as maintenance.

Application of fertiliser P to Fe chlorosis-inducing soils is likely to aggravate this deficiency. However, this effect depends on the plant and the Fe and P statuses of the soil. Background: Iron (Fe) deficiency chlorosis, a major nutritional problem in plants growing on calcareous soils, is related to the content and reactivity of soil iron oxides and carbonates.

South-western Australia harbours a biodiversity hotspot on severely phosphorus-impoverished soils. Threats include eutrophication due to phosphorus enrichment, due to increased fire frequency and spraying with phosphite to reduce the impacts of the introduced pathogen Phytophthora cinnamomi. We propose a strategy to work towards alternatives to phosphite for pathogen management.
