Bumed limestone from the magnesium limestone contains 

 from 50 to 60 per cent of calcium oxide, and 30 per cent 

 or over of magnesium oxide. 



The growth of the tree will generally indicate the 

 need of fertilizers. When the tree looks scrawny and 

 stunted and either no growth or but a few inches of annual 

 growth are being made, fertilizers are needed. Nitrogen 

 appears to a greater extent in the leaves and encourages 

 strong wood growth which is desirable in old trees not 

 growing vigorously. Potash is the basis of the fruit acids 

 and is also a color factor. Phosphoric acid insures pro- 

 per ripening of both fruit and tree. Lime strengthens the 

 limbs, hastens the ripening of the fruit and has a tendency 

 to give a steady growth to the tree. 



Barnyard manure applied at the rate of 10 loads per 

 acre supplies the necessary nitrogen, phosphoric acid, and 

 potash, and will also add huraus and improve the physical 

 condition of the soil. 



When manure is not available, and the trees are not 



making the proper growth, the following fertilizers per acre 



are recoimnended by the Geneva Station: 



75 lbs. nitrate of soda 

 400 lbs . bone meal 

 150 lbs. sujiphate of potash 

 1500 lbs. fresh-burned lime
