Field mustard (Brassica Arvensis) and oats (Avena Sativa) were grown in pot cultures in a greenhouse. Soil moisture was kept at 15, 30, and 45 per cent of the moisture-holding capacity of the soil. The plants were sprayed with solutions of iron sulfate varying in strength from 5 to 15 per cent and with solutions of sulfuric acid varying in strength from 1 to 2 per cent. Sprayed plants were exposed to three conditions of relative humidity: 30, 60, and 100 per cent. Iron sulfate was more effective as a herbicide under conditions of high humidity. Sulfuric acid was more effective under conditions of low humidity. Iron sulfate is more effective at lower temperatures, while sulfuric acid is more effective at higher temperatures.
