AB Potted eastern white pine seedlings treated with four rates of 20-20-20 fertilizer were grown at a site in central New Jersey that is exposed to elevated levels of ambient ozone pollution. Symptoms of ozone toxicity did not develop on the conifer and growth of white pine was not reduced by ozone pollution. The recommended rate of fertilizer application was optimum for Eastern white pine. The omission of fertilizer and one-half the recommended fertilizer generally led to chlorosis, relatively short candles and low vigor. Doubling the recommended fertilizer rate led to shorter candles and toxicity symptoms on the needles.
