AND ITS RELATION TO THE GROWTH OF TOBACCO H. G. M. JACOBSON AND T. R. SWANBACK In a preliminary report (6), the authors called attention to certain identical symptoms exhibited by tobacco when grown in solutions containing considerable manganese and on highly acid soils with an appreciable soluble manganese content. During the past 2 years the subject has been more fully investigated along the following lines: (a) Verification of definite manganese toxicity symptoms with tobacco; (b) analyses for manganese of soil and plant material, under various fertilizer treatments; (c) the effect of different increments of lime on the manganese (active) content of soil and plant material; (d) the active manganese content of 22 Connecticut soils before and after liming; (e) total and active manganese in 33 Connecticut soils from three sections of the state; (f) manganese content of leachates from greenhouse and lysimeter soils; and (g) distribution of manganese in the tobacco plant.
