Phosphorous ( P ) in Plants and Soil


Phosphorous is essential for the best possible crop yields and is a challenging nutrient to understand and manage.
Phosphorous enables photosynthesis and respiration, storage and transfer of energy, and is involved in root, flower and fruit development through cell division.
Soils generally contain large amounts of total phosphorous, with most in insoluble forms that are unavailable to plants. Phosphorous availability is limiting to crop growth in many agricultural soils.

Phosphorous does not exist in soils in its simple elemental form.  Phosphorous exists as inorganic or organic, with organic being chemically bonded to a carbon compound.
