Synopsis A zinc deficiency was found to be caused by inactivation of soil zinc by decomposing organic matter. Zinc was found to increase in the acid extractable and H 2 0 2 extractable fractions of the soil and to decrease in the water extractable and exchangeable portions as length of incubation time of the added organic material and soil increased from 6 to 12 weeks.
