Abstract

Phosphorus (P) is an essential nutrient required by
potatoes and all other plants. Potato plant roots readily
absorb P in the form of phosphate from the soil ( water)
solution. The absorbed phosphate moves upward
and downward in the plant. Phosphorus-deficient potato
plants transfer P from older tissues to actively growing,
younger tissues.
Symptoms of P deficiency include darker green, stunted,
spindly leaves with younger leaflets that turn upward
or curl. With prolonged deficiency, plants are
small and have reduced leaf area.
