ON FIELD AND FLOWER GARDEN 



early crops, these are the ones to use, especially 

 in the early part of the season. 



Nitrogen is quite often in the form of ammonia 

 in the fertilizer. Ammonia is very volatile and 

 escapes into the air rapidly if not properly in- 

 corporated. A commercial product that has a 

 strong odor indicates that the ammonia is escap- 

 ing into the air. 



Use a fertilizer when it is absolutely necessary, 

 but make sure first that some cheaper process, 

 such as cultivation, irrigation, drainage, or rota- 

 tion of crops, will not accomplish the same result. 



The physical condition of the soil in practically 

 every case is more important than the chemical 

 condition, that is, it has a more direct effect upon 

 the crops. 



INCREASING CROPS BY ROTATION 



Many flower lovers have been dismayed at 

 having a favorite collection of lilies almost entirely 

 destroyed by insects. Such a disappointment can 

 be generally prevented by moving the lily bulbs. 



Great fields of grain, and large orchards of 

 valuable fruit trees have produced smaller yields 

 year after year 'until it was finally impossible to 

 grow a profitable crop at all. 



The remedy is rotation. 



Each grower must be his own doctor, however. 

 There is no short cut to profitable crop yields.
