Die Ammoniak-Und Saltpeterdüngungs-Frage (The Ammonia and Saltpeter Fertilization Question) by Paul Wagner, published in 1912, delves into the agricultural and chemical aspects of using ammonia and saltpeter as fertilizers. This historical work examines the effectiveness and practical application of these substances in promoting plant growth and improving crop yields.
