A 6-year study was conducted to determine the effect of working to a depth of 24 inches on the productivity and chemical and physical condition of a Solonetz soil. Productivity was generally increased during the second rotation by deep working. The extractable calcium content of the A and B horizons was increased and the sodium content decreased. The magnesium distribution was not changed. An intractable B-like horizon reformed in the deep-worked plots. No relationship was found between productivity and the balance of extractable cations.
