The total Pconcentration in agriculturalcrops generally varies to and Transport of PhosphorusPhosphorus enters theplant through root hairs, roottips, and the outermost layersof root cells.
Phosphorus plays a vital role in virtually every plant process that involves energy trans-fer. High-energy phosphate, held as a part of the chemical structures of adenosine diphos-phate (ADP) and ATP, is the source of energy that drives the multitude of chemical reactions within the plant. When ADP and ATP transfer the high-energy
