PHOSPHORUS--DEFICIENCY
Plants deficient in phosphorus may have a purplish
cast on the underside of the leaves (corn) or purplish/red leaves and
stems (tomatoes). Flowering and fruiting will be limited. Plants will
be slow to form new roots and establish. Plants are slow growing. Premature
fruit drop may occur.
Phosphorus may be deficient in a plant in early spring
following a cold, wet spell. However, plants will generally recover.
