a crop of timothy and a crop of corn must be supplied before 

 the wheat rotation is reached. In many cases, simply top 

 dressing with the Nitrate will be found effectual. In all 

 cases where the acre yields have fallen off, top-dressing of 

 Nitrate of Soda should be applied. 



Professor Maercker states that Nitrate of Soda for 

 wheat is absolutely necessary under the conditions in Ger- 

 many, and that lOO pounds of Nitrate of Soda produces 300 

 to 400 pounds of grain and a corresponding amount of straw.

Lack of Nitrogen in the soil is detrimental to 

 the size and quality of the fruit. The cheapest 



and most available 

 Ammoniate is Ni- 

 trate of Soda. A few 

 cents worth applied 

 to each tree will give 

 the largest possible 

 yield of choicest 

 fruit, returning many 

 tmies Its cost.

Nitrate of Soda 

 on Apples. 



Apple: 

 show the most improvement where Nitrate 

 of Soda was applied. For apple trees in 

 grass the following fertilizer is recom- 

 mended: Nitrate of Soda i to 5 pounds. Sulphate of potash 

 I to 5 pounds, S. C. phosphate rock 4 to 10 pounds; the 

 quantity used to be varied according to the size of the tree. 



Fertilizers for the Peach : The fertilizer 

 recommended, depending upon the size of 

 the trees, is substantially the same as for apples, except that 



Peaches.
