1 Check (Unfertilized). 



2 Nitrate, 2i lb.; Dried blood. 3i lb.; Acid Phosphate, 10 lb. 



3 Nitrate, 2^ lb.; Dried blood, 3i lb.; Potash 2 lb. 



4 Acid phosphate 10 lb.; Potash 2 lb. 



5 Check 



6 Nitrate, 2i lb.; Dried blood, 3^ lb.; Acid phosphate, 10 lb.; 



Potash 2 lb. 



7 Same as No. 6, plus lime, 12 to 25 lb. 



8 Manure, 400 lb. 



9 Check 



This test should be located in a typical part of the 

 orchard, and should include not less than 5 average trees 

 of the same variety and age, in each plat. All the trees 

 should be labeled and carefully measured at a fixed point 

 on the trunk, and definite records of their growht and yields 

 sihould be kept for at least 3 years. Frequently, good in- 

 dications of the orchard's needs may be obtained in less 

 time than this, but at least this period should be allowed 

 and more should be used when necessary. 



The same time and methods of application should be 

 followed as described above. The materials are indicated 

 here in amounts per bearing tree instead of per acre as 

 above, and the same proportionate reductions should be 

 made for younger trees. In other words, if only a third of 

 the ground is to be covered, then only about a third of, these 

 amounts should be used, if the rate of .application is to be 

 kept within proper bounds. 



on the trunk,- and definite records of their growth and yields 

 kept ,within proper bounds. This test or its equivalent 

 properly carried out, will give one a more exact knowledge 

 of the real fertility needs of his orchard than can be secured 

 in any other way now known. 



QUESTION. Were these trees in sod f. 



DR. STEWART. The fertilized trees were. 



MR. BARNES. I would like to ask the Doctor what 

 the character of the foundation of the soil. was in different 

 cases. 



DR. STEWART. Well as I have said, we have got 

 about ten different soil types, so that they vary all the way
