Abstract Not Available – First paragraph follows:
POTASSIUM DEFICIENCY OF CITRUS in California had not been recognized prior to about 1960. Since then, experimental work has led to a greater understanding of potassium nutrition and the effects of potassium levels (as determined by leaf analysis) on yield and fruit quality of oranges, lemons and grapefruit.
