TOP DRESSING TALKS 



Tne orchard needs a top dressing of quickly-available nitrogen, and will 

 respond to it just as quickly and surely as timothy, winter grains or vegetables. 

 Notning brings young orchards into bearing so quickly or keeps ^e older 

 trees in profitable condition so surely. 



The best nitrogenous fertilizer for orchard use is ARCADIAN Sulphate 

 of Ammonia. It carries more ammonia (253<4% guaranteed) than any other, 

 consequently) less freight. It is all soluble, quick acting and all available, 

 besides being easy to spread bj) hand or by machine. 



Arcadian Sulphate of Ammonia 



ARCADIAN Sulphate of Ammonia is the well-known standard article 

 that has done you good service in your mixed fertilizers for years past. Espe- 

 cially kiln-dried and ground to make it fine and dry. Ammonia 2534%. 



Made in U. S. A. Arcadian is the Great American Ammoniate.

(Itisl versus liquitl. In the case of liquid 

 npplicalions some fifiiires are available 

 Willi reference to the use of spray gun 

 and spray rod. A detailed account of 

 co.st records will not be presented in 

 this article. In suniniarizing, it might 

 be said that records were taken on 

 three acre units, trees upon which were 

 14 years of age. As an example of this 

 in 1917 six applications of spray were 

 used to control apple scab and codling 

 moth. In some of the applications the 

 lime sulphur — or dust sulphur — and 

 arsenate of lead were used separately 

 and at other times in combination. The 

 complete record shows that from the 

 standpoint of cash outlay to the grower 

 the comparative costs are about on a 

 par — the dusting method being slightly 

 more costly. It was found that it took 

 two men thirty-six and one-half hours 

 to spray three acres six times with rods, 

 while the same acreage was dusted with 

 the same crew and team in eight hours. 

 On the face of figures submitted it 

 would then appear, taking all things 

 into consideration, especially the time 

 element, that the dusting system had the 

 edge on the liquid method. The 1917 

 figures, however, were obtained before 

 the spray gun came into use in the Hood 

 River section. The figures that have 

 been submitted, however, do not give 

 the various factors that have to be 

 taken into consideration in applying a 

 good coat of dust — and herein lies the 

 one great factor which makes its use 

 impracticable under Hood River condi- 

 tions. This all-important factor is the 

 uncontrollable wind. Wind, and to be 

 more explicit, a very slight breeze, 

 paralyzes the dusting method. It not 

 only makes the accomplishment of good 

 work impracticable but impossible. In 

 employing the dusting method for pest 

 control the air is considered the car- 

 rier. The dust is thrown with force 

 into this theoretically quiet medium, 

 and so thrown covers the under sur- 

 faces of the fruit and foliage. In hover- 

 ing and slowly settling the upper sur- 

 faces are coated. With conditions ex- 

 actly right a wonderful coating can be 

 given a tree in all of its parts, a coating 

 which has remarkable adhesive quali- 

 ties. With a light breeze blowing — and 

 this means light in its strictest sense — 

 the properties involving the carrying 

 qualities are greatly impaired. Instead 

 of the materials naturally hovering over 

 the trees as is the case in quiet atmos- 

 phere, a large percentage of the minute 

 particles quickly pass by the fruit and 

 foliage, a large percentage of which is 

 lost. Only those particles which actu- 

 ally strike surfaces — and perhaps not 

 all of them — stick. The result is a loss 

 of a large percentage of the materials
