In the matter of fertilizers, the peach-grower early learns humility. He is no sooner certain that his trees must be fertilized and that he has at last hit upon the right formula than his check plats or his neighbor's orchard convince him that he is not getting the worth of his money in fertilizers. In eastern New York, peach-orchards are very generally fertilized and rather heavily, the amounts and formulas being nearly as diverse as the men applying them. In western New York, commercial fertilizers are comparatively little used in peach-orchards. Experiments in fertilizing peaches in progress at this Station are inconclusive and there is nothing to offer from the work here as to what the peach needs in the way of plant-food. In the present state of our knowledge, about the best the peach-grower can do is to assume that, if his trees are vigorous, bearing well and making a fair amount of growth, they need no additional plant-food. If they are not in the condition described, look to the drainage, tillage and health of the trees first and the more expensive and less certain fertilization afterward. More and more, in western New York at least, growers are carrying on simple experiments to obtain positive evidence as to what elements of plant-food their trees need. The following is an example of such an experiment: (1) Acid phosphate to give about 50 lbs. of phosphoric acid to the acre; (2) phosphate as above and muriate of potash to give 100 lbs. of potash to the acre; (3) phosphate and muriate as above and nitrate of soda and dried blood to give 50 lbs. of nitrogen per acre; (4) six tons of stable manure is applied on a fourth plat; (5) a similar plat is left unfertilized for a check. No fallacy dies harder than that fertilizers will cure yellows. Nitrate of soda is a great rejuvenator of trees suffering from yellows brought on by sod or lack of tillage but no fact in peach-orcharding has been more thoroughly demonstrated than that neither this fertilizer nor any other will in the least benefit trees suffering from true yellows or from the somewhat similar trouble, little-peach.
