The effect of ammonium sulfate on soil reaction
1931
White, J.W.
Ammonium sulfate, under the conditions of the Pennsylvania field plat experiment, increased soil acidity in proportion to the equivalent of 1 molecule of dibasic acid for each molecule of ammonium sulfate applied. The theoretical lime requirement based on the formation of one affective molecule of dibasic acid for each molecule of ammonium sulfate applied compares with the average actual lime requirement as follows: (...). The average difference between the theoretical lime requirement (pounds of ammonium sulfate multiplied by 0.757) and that actually found represents less than 1 cc of N/28 lime water or 1 cc of N/50 sodium hydroxide in terms of the author's method.
