Excerpt from The Fertilization of Apple Orchards
As in the Ohio experiments, the Oregon tests were also arranged so as to permit a study of the influence of fertilizers upon devitalized trees. 7 In this case, however, the orchards were under cultivation instead of in sod but had become depleted in fertility through constant tillage with no cover crops returned to the soil. Here again the starved trees responded to applications of nitrate of soda by out-yielding the check trees 11 to 1 in one orchard, and in another orchard actually out-stripped the checks 24 to 1. Phosphorus and potassium are reported as inactive in these orchards. Both Oregon and Ohio call attention to the necessity of applying the fertilizer before the blossoms open in order to get maximum results.

Paperback. Zustand: New. Print on Demand. This book examines apple orchard fertilization practices that have been employed in West Virginia since the 1910s. The author has compiled data from four separate experiments comprising 368 trees of various ages and conditions. All trees in the experiments received clean cultivation and cover crops. The results of the individual experiments varied widely, though some general insights can be gleaned from the cumulative data. No conclusive evidence suggested that commercial applications of potassium had any effect on apple orchard yields in West Virginia. Phosphorus also appeared to have little direct effect on fruit quality or yield, although it did promote the growth of cover crops and sod coverings. Nitrogen, on the other hand, was shown to increase both the size and yield of apples, especially when combined with phosphorus. However, it had some negative effects as well, delaying fruit and tree maturity and diminishing the development of red coloration. The author concludes that while nitrogen fertilizers can be beneficial in some situations, especially for reviving neglected or starved trees, they must be used with care and in conjunction with adequate sunlight to avoid diminishing the quality of the fruit they produce.
