Food for i n certain cases, such effects have been most marked. 



When it is desired to use a larger amount than one 

 *3* hundred pounds per acre of Nitrate of Soda as a Top- 

 Dressing, or in any other way, there should be present some 

 form of Phosphatic and Potassic Plant Food, and we recom- 

 mend not less than two hundred and fifty pounds of either 

 Acid Phosphate or fine ground Raw Rock, and two hundred 

 and fifty pounds of some high-grade Potash Salt, preferably 

 the Sulphate, or wood ashes in twice this quantity. A much 

 larger amount than one hundred founds of Nitrate per acre, 

 when used alone on staple crops, is generally sure to give an 

 unprofitable and unbalanced food ration to the plant. For 

 Market Gardening Crops, Hops or Sugar-Beets, however, 

 somewhat more may be used alone. 



When the above amounts of Phosphatic and Potassic 

 Fertilizers are used, as much as three hundred pounds of 

 Nitrate of Soda may be applied with profit. In applying 

 Nitrate in any ration it is desirable to mix it with an equal 

 quantity of land plaster or fine, dry loam or sand. 



If you have any reason to suspect adulteration of the 

 Nitrate you may buy, send several pounds of it to your 

 Experiment Station for analysis, giving date of purchase, full 

 name and address of agent, and of the Company which the 

 seller represents. 



Generally on the Pacific Coast Nitrate may be applied 

 as a Top-Dressing after the heavy Spring rains are over, but 

 before crops attain much of a start.
