say that the Yellow Transparents which had been treated had nearly 

 doubled the quantity of apples, Wealth}' contained more, it increased the 

 jdeld of the Grimes a vast amount. Steel Reds just coming into bearing 

 had from a few apples to a bushel per tree, and I do not believe on the 

 other ten or fifteen rows of apples in the sod there were more than a dozen 

 Steel Reds all told. 



Going back to the early spring of 1919 on account of the splendid 

 results I had obtained in my little experiment the previous year I decided 

 to use more acid phosphate, and applied in the ncighborhoood of eight 

 tons to my bearing orchards, trying to apply as nearly as possible from 

 eight to ten pounds per tree on the old trees and about four pounds per 

 tree on the younger ones. In 1919 I was able to get some sulphate of 

 ammonia in addition to the acid phosphate. I applied this to one row- 

 across the young orchard putting on about 23^ or 3 pounds per tree, and 

 it is worthy of special mention that a part of this particular row where 

 the sulphate of ammonia was applied, crossed a part of the orchard 

 which w'as under cultivation. And what was the result with all this 

 expense and work? I could see no beneficial results whatever on tree 

 growth, or foliage all summer where I had applied acid phosphate alone 

 on the sod portion of the orchard. What was the troulile when I had 

 derived such striking benefits the previous year? Was it the season? 

 Possibly in part, but I am inclined to the opinion that I did such a thor- 

 ough job of spraying during the early summer in my frantic endeavor 

 to eliminate scab that I burned off much of the foliage with the mixture 

 used. It is interesting to note that on the sod, where the sulphate of 

 ammonia had been applied in addition to the phosphate, in spite of the 

 burning tendencies of the spray mixture used the foliage remained fine 

 and thrifty all summer, as did the w'hole block under cultivation, which 

 understand had a good application of acid ))hosi)hate witli Init the one 

 row receiving in addition the ammonia. These trees under cultivation 

 received thorough culture — a cover crop of vetch and rye having been 

 turned down wdien the rye was about two feet high. W^here I had used 

 the ammonium sulphate on the sod the foliage remained as good as the 

 trees under cultivation or nearh^ so. This particular part of the row 

 in the sod which had received sulphate of ammonia in addition to the 

 acid phosphate, produced an abundance of fruit buds, and held the 

 foliage until late fall. There was no apparent benefit resulting in the 

 part of the row in the cultivated portion where the sulphate of ammonia 

 had been used over the balance of the orchard under cultivation. This 

 would prove to my mind so far as my soil is concerned sulphate of am- 

 monia, or nitrate of soda would not be a paying proposition if acid phos- 

 phate was used in conjunction with vetch and rye or some good nitro- 

 genous cover crop and cultivation methods employed. 



Last spring I bought a duster, and while I am still a little skeptical 

 about its controlling scab and worms as well as the liquid spray, I cer- 

 tainly did not burn off my foliage, and it was a great contrast to the 

 foliage seen by many members of this society the year previously. I 

 am still of the opinion that part of the good foliage however may have 

 been due to the acid phosphate applied in 1919 but I used considerable 

 nitrate of soda and sulphate of ammonia this past summer. The nitrate 

 of soda was put on rather late, a little after blossoming as I remember. 

 The foliage I believe was benefited and 1 am confident I will get good
