Storage tests on apples indicated that orchard applications of nitrate of soda had an unfavorable influence on storage capacity. As this effect appeared to be greatly restrained by drouth in 1930, experiments were carried on in 1931 to determine specifically the effect of differential treatments of nitrate of soda and water to trees suffering from dry weather.
