Abstract
Two foliar applications of 6.00 or 9.00 kg/ha of MnSO 4 (from MnSO 4 ∙H 2 O) on flue-cured tobacco, grown on a Fox sandy loam low in available Mn, increased the Mn content of green and cured leaves but did not affect the levels of Fe and Cu.In greenhouse experiments with the same soil, applications of 120 kg/ha MnSO 4 , with and without S or superphosphate, raised the Mn content of oats and leaves and stalks of tobacco. Sulfur applied at 1122 kg/ha, with or without MnSO 4 , raised the Mn content of oats and tobacco and lowered the pH of the soil. Applications of 978 kg/ha P (from 20% superphosphate), with or without MnSO 4 , lowered the soil pH and increased the Mn content of oats; in conjunction with the high, rate of MnSO 4 , applied P raised the Mn content of tobacco stalks and top leaves. Apparently the enhancement of Mn uptake by the application of S or superphosphate is due to the decrease in soil pH.
