98 Report of the Acting Director and Chemist of the 



Suggestions. — Excessive application of nitrogen compounds to 

 apple orchards is to be avoided because it favors rank growth of 

 tree at the expense of fruit. Fruit trees in bearing require annual 

 application of fertilizers for best results. Apj^lications may be made 

 in fall or spring.

 one acre. 



20 to 40 



30 to 60 



35 to 70 



Pounds of different materials for one acre. 



120 to 240 lbs. nitrate of soda ; or 

 200 to 400 lbs. dried blood ; or 

 4,000 to 8,000 lbs. stable manure. 

 300 to 600 lbs. bone-meal ; or 

 200 to 400 lbs. dissolved bone-meal or 

 bone-black ; or 

 250 to 500 lbs. dissolved rock. 

 70 to 140 lbs. muriate ; or 

 70 to 140 lbs. sulphate ; or 

 300 to 600 lbs. kainit ; or 

 700 to 1,400 lbs. wood-ashes. 



Suggestions. — Stable manure may be applied every two or three 

 years in the fall after removing plants, and also every year a dress- 

 ing of phosphoric acid and potash. Nitrate of soda is applied to 

 best advantage in the spring, just as the shoots begin to appear.

75 to 150 lbs. nitrate of soda ; or 

 50 to 120 lbs. sulphate of ammonia ; or 

 125 to 250 lbs. dried blood ; or 

 2,500 to 5,000 lbs. stable manure.

 200 to 400 lbs. kainit ; or 

 500 to 1,000 lbs. wood-ashes. 



Suggestions. — Excess of nitrogen as found in stable manure is to 

 be avoided, because the quality of the grain may be injured.
