Injury to growing crops caused by the application of arsenical compounds to the soil
The results of transpiration studies with oats in water cultures show conclusively that arsenic added as arsenic trioxide decreases transpiration even when added at the rate of one part per million. The characteristics of treated plants are narrower leaf blades and a lighter color. Decreased transpiration resulted when arsenic trioxide was added at the rate of 10 parts per million or more to soil in which tomato plants were growing. Similar results were obtained when sodium arsenite or potassium arsenite was substituted for arsenic trioxide. The addition of small quantities of soluble arsenical compounds to potted plants caused serious injury to most of the plants under test. As a rule the cereals were hardier than the other crops. Turnip was also fairly resistant. The arsenites were decidedly more toxic than the arsenates. 16 references, 6 figures, 13 tables.
