the soil. A rich dark loam or a soil producing legumi- 

 nous crops continually for any length of time will need 

 but little nitrogen and in many cases none at all. Fre- 

 quently such soils ^contain so much nitrogen as to cause 

 gummosis in young trees and potash and phosphate 'must 

 be applied to rectify the trouble. 



Formula No. 4 for leguminous plants : Leguminous 

 plants can supply themselves with nitrogen from the air 

 by means of bacteria which live in nodules on the roots, 

 but as they can obtain no nitrogen before such nodules 

 have formed it may be necessary to apply some for the 

 first crop on poor sandy soils. A good formula for such 

 is as follows : 



250 Ibs. Nitrate of Soda 



600 Basic Slag 



300 Muriate ol Potash 

 850 Dry earth as filler. 



2000 Ibs. 



or 



200 Ibs. Sulphate of Ammonia 

 3oO Double Acid Phosphate 

 300 Muriate or Sulphate of Potash 

 1200 Dry earth as filler. 



2000 Ibs. 



This can be applied to three acres either with the 

 filler or without. That is, the application should be about 

 633 Ibs. per acre of the last formula with filler, or 266 

 Ibs. without filler. For the second and successive 'Crops 

 the nitrogen may be omitted entirely. 



HOW TO TAKE CARE OF THE GROVE 



The young trees should preferably be mulched as soon 

 as planted. If no muLch is available the soil should be
