Food; for Nitrate for Experiments. 



^° ^ As Nitrate is a Powerful Plant Tonic and Energizer tt is NOT a stimulant 

 156 tn any sense of the word; a very small quantity does a very large amount of 

 work. Broadcast the Nitrate as soon as the frost leaves the ground 

 in the spring. 



I never recommend the use of Nitrate of Soda alone, except at the rate 

 of not more than one hundred (100) pounds to the acre, when it may be used 

 without other fertilizers. The phosphatic and potassic manures should 

 usually be applied in connection with Nitrate of Soda at the rate of about 

 two hundred and fifty (250) pounds to the acre of each, or if used on the 

 plots (20 ft. by 20 ft.) not more than three pounds of each should be applied 

 thereto. One hundred pounds per acre you will generally find profitable for 

 all crops. It will be found quite satisfactory also in its after effect and in 

 perceptibly sweetening sour land. 



According to Dr. Wheeler's experiments 

 in Rhode Island soils are less exhausted 

 when complete fertilizers are used with Nitrate than when 

 no Nitrate is used. The Soda always left behind after the 

 Nitrate of Soda is used up conserves always the Lime and 

 Potash, and unlocks the soil Silicates and thereby frees 

 Lime and Magnesia. The Feeding value of Hay is far 

 greater when Nitrate is used as a fertilizer in this con- 

 nection. 



Rhode Island Formula: 



Nitrate of Soda 300 lbs. 



Sulphate of potash 200 lbs. 



Acid phosphate or its equivalent in Thomas slag 400 lbs. 



Manures. 



Dr. Voelcker, F.R.S., made analyses of fresh and rotted 

 farmyard manures. These analyses show a larger percent- 

 age of soluble organic matter in rotted than in fresh manure. 

 The fresh manure contains more carbon and more water, 

 while in the rotted manure the Nitrogen is in more available 

 form for root-absorption. 



If the process of fermentation has been well managed, 

 both fresh and rotted manures contain the same amounts of 

 Nitrogen, phosphoric acid, and potash. 



There should be a sufficient amount of 



litter to absorb and retain the urine and 



also the ammonia formed in the decomposition of the manure. 



Leaves, straw, sawdust, moss, etc., to which is added some 



peat, muck, or fine, dry, loamy earth, mixed with gypsum
