CANADIAN FERTILIZER EXPORTS 

 (Years ended Mar. 31) 



Ashes, Pot and Pearl 



Ashes, all other 



Fertilizers "not otherwise 



provided" 1,594,785 . . . 2,171,352 



Of this, 116 bbls. were foreign produce. 



Cyanamide, manufactured at Niagara Falls, is exported to United States, as the 

 Canadian market takes only a portion of the product. The exportation of potash 

 and of liquor containing potash from beet sugar factories is prohibited. The question 

 of prohibiting the export of wood ashes is under consideration. 



With muriate of potash at $400 per ton, wood ashes containing 5% potash would 

 be worth $2.00 per hundred pounds for the potash alone.

FARM DRAINAGE 



PROF. W. H. DAY, Agricultural College, Guelph, Ont. 



Perhaps few will question the statement that, with ordinary soils, the most impor- 

 tant factor in crop production is the correct amount of water in the soil during the 

 growing season. In the arid regions of the West where dry farming is practised, 

 summer-fallowing is resorted to once in two or three years in order to conserve sufficient 

 moisture for the production of crops in the remaining years. In humid sections, such 

 as Ontario, Quebec and the Maritime Provinces, there is always a part of each year 

 when considerable areas of land contain excessive moisture. If the excess occurs 

 during the growing season and continues longer than a day and a half to two days, 

 injury to crops will result. There is also the danger of drought, which in humid climates 

 cannot be guarded against by dry farming methods as can be done in arid climates. 

 For both extremes there is a common corrective, viz., to tile drain the land. Obviously, 

 this will remove the excess moisture when such is present, but, just as certainly, it 

 provides a greater supply of moisture for the crops in time of drought. This is effected 

 in two ways: First by rendering the soil more porous and consequently capable of 

 retaining more moisture when the excess has drained away; secondly, by permitting 

 the roots to penetrate deeper than in undrained soil, thus providing them with a deeper 

 feeding ground from which to draw moisture in time of drought.
