Abstract

Synopsis Fourteen plant species were grown on Tulare clay: 7 developed zinc deficiency; 2 developed iron deficiency; and 5 had no deficiency. Added phosphate accentuated both zinc and iron deficiencies. Added zinc caused iron deficiency in corn and millet but in no other plants. Nutrient‐element balance is a critical factor in the management of Tulare clay.
