Hunger Signs in Crops

Abstract

UNHEALTHY growth of crop plants, apart from trouble induced by diseases or pests, is usually associated with physiological causes, which in some cases imply excess or deficiency of various substances utilized in the metabolism of the plant. The relative quantity of these substances is immaterial, as the plant suffers as much from a deficiency of an element such as boron, of which only a minute trace is required, as from a deficiency of a major element, such as nitrogen, required in large quantities. In practice it is deficiency rather than excess that is most likely to occur, and various signs and symptoms present themselves.
