Phosphorus Dynamics: From Soil to Plant
Phosphate can precipitate with Ca, generating dicalcium phosphate (DCP) that is available to plants. Ultimately, DCP can be transformed into more stable forms such as octocalcium phosphate and hydroxyapatite (HAP), which are less available to plants at alkaline pH (Arai and Sparks, 2007). HAP accounts for more than 50% of total Pi in calcareous ...

New mechanistic insights into phosphate-starvation-regulated plant
Phosphorus (P) is an indispensable macro-nutrient for plant growth that is absorbed by plants in the form of inorganic phosphate (Pi). Pi deficiency is a major challenge limiting crop productivity worldwide. To combat Pi scarcity and maintain Pi homeostasis, plants have evolved different strategies for efficient Pi acquisition (Paz-Ares et al., 2022). Plants …

The Importance Of Phosphorus As A Fertilizer For Plant
Soil pH, or the level of acidity or alkalinity in the soil, has a significant impact on the availability of phosphorus to plants. Phosphorus exists in different chemical forms in the soil, and its availability is greatly influenced by the pH level. In acidic soils with a pH below 6.0, phosphorus tends to become less available to plants.

Phosphate acquisition and metabolism in plants
Phosphorus (P) occurs in oxidized forms in natura, most commonly as orthophosphate (PO 4 3–).Plants acquire P almost exclusively by transporting soluble inorganic H 2 PO 4 – (Pi) from the soil into their roots. The Pi concentration in most soil solutions ranges between 0.5 and 10 μM, whereas the optimal intracellular Pi concentration is 5–20 mM.
