From the introduction: "The present book describes a method of recognising by sight deficiency symptoms of the various mineral plant nutrients in commonly grown agricultural and horticultural crops. Where the method can be used it provides the quickest means of determining the causes of crop failures due to mineral deficiencies (also to some mineral element toxicities) and it will often enable full crop to be harvested with little expenditure of time, materials and labour, when otherwise total failures might result."
