In connnection with a 1974 survey of 22 western states, we agreed to gather information on the types of crops in California taht are subject to iron deficiency and to estimate the acreage involved. Recognizing that the severity of the problem veries from year to year because of weather conditions, we concluded that the most useful information would be obtained from members of Copperative Extension who have long familiarty with field conditions in the various agricultural sections of the state. therefore, the information summarized below was obtained from Country Farm Advisors throughout California.
The author is indebted to the following persons who made the survey possible: George B. Alcorn, formerly Director of Cooperative Extension: J.J. Coony, Assistant Director of Cooperative Extension; Roy L. Branson, Soils and Water Specialist, Cooperative Extension; and unknown numbers of county Farm Advisors who gave consideration to our request for information
