Re: Re: trace elements generally


In 1954, "The Care and Feeding of Garden Plants" was published by Prentice-
Hallby Am. Sox. for Horticultural Science & National Plant Food Institute. It
has wonderful color plates of plants with deficiencies.  Whe I see unusual
leaf coloring I take a look at this book.  Maybe you can find it at a used
book store.  Anna Mae Kalamazoo zone 5
