Miss Mildred Jones' reply, fortunately, goes into other and equally important phases of the same subject. She says: "Anyone who is going to lime and fertilize nut trees should take at least a five year period for his work, using lime and fertilizer each year, and not dump it all in one year, then wait for results. He should study the return on a five year basis. One year is too short a term. Weather conditions can upset a program to the extent that both lime and fertilizer may not have their effect until the following year. Let those who really want to know, make graphs of growth in young trees and of nut production from older trees, in pounds, for five years, as against five of the same years during which trees similarly situated received no fertilizer or lime. "I shouldn't be at all surprised if those who state in reports to you that they have an acid soil, merely have a top acid soil. They may be growing their trees in basic limestone soils. Walnut trees grow in this environment very well, because they are found growing wild in woods where laurel and other types of plants loving an acid condition grow. This is true here in our county, but these soils are not seriously acid. They grow good garden crops. "Ground, or pulverized, limestone is the safest type of lime to apply to trees or crops, in my estimation. Some of it is ground so fine that it looks like hydrated lime and is used for medicinal purposes. I am inclined to think that any reports you received that noted injury from the use of lime may have been due to the use of burned lime (calcium oxide) which is caustic when wet. This type of lime may be used in winter, but during the growing season, or too close to the growing season, may injure trees. I believe such injury depends entirely upon weather conditions, but it is a good thing to be on the safe side and use a lime which will not have the hot reaction that burned lime has. "Your reports will serve an excellent purpose if they lead to getting a yearly record by planters on bearing and tree growth of their varieties. Few people know enough to go into the matter of soils and treatments intelligently. One can hardly blame them. It is a baffling subject. An unbalance in one element will lock up another element until one has quite a time unlocking them again. It seems that a conservative middle course is about the best to advise." Upon reflection, it seems likely that if our questionnaire had asked specifically about the use of lime, many more reports would have been received of its use.
