Summary
An experiment is described in which the effects were studied of deficiencies of boron, copper, manganese, molybdenum and zinc on timothy grown in solution culture.
Characteristic symptoms of copper, manganese and zinc deficiencies developed and are described.
No symptoms of boron or molybdenum deficiencies appeared; plants given no molybdenum gave bigger dry matter yields than controls.
Iron deficiency appeared fortuitously in some treatments but not in others.
These results are discussed with reference to previously published work on similar lines.
