Investigations were conducted to measure the quantities of NH 3 physically sorbed and the quantities of sorbed NH 3 retained against evacuation by some common plant residues when exposed to NH 3 in a dry condition and with different amounts of moisture. With increases in NH 3 pressure both moist and dry samples of each plant residue physically sorbed increasing quantities of NH 3 . When saturated with NH 3 , evacuated, and then saturated a second time each dry plant material sorbed less NH 3 during the second than during the first saturation. Increases in moisture content resulted in increases in physical sorption of NH 3 across the entire range of partial pressures of NH 3 employed. Saturation of the moist plant residue samples with NH 3 resulted in some measurable increases in NH 3 content after evacuation.
