CROPS AND FERTILIZERS 



strain again when poured into the spray pump. 

 While copper solution will retain its strength 

 indefinitely, still the lime mixture is never as 

 good as within an hour or two of the time it is 

 made. For insects add one pound of Paris 

 green to a hundred gallons of Bordeaux mix- 

 ture. The harvesting of a potato crop is done 

 by a machine which digs, sorts, and throws the 

 potatoes to one side. 



Oats and peas are used to supply green food 

 to cows, and are planted at the rate of one and 

 one-half bushels of Canadian field peas to one 

 and one-half bushels oats. Spread on the fer- 

 tilizer, plough, harrow with a spring tooth or 

 disk harrow, broadcast the peas, then harrow 

 again with a spiked-tooth harrow. In three or 

 four days broadcast the oats and harrow them 

 in. 



The root crop will come next on the planting 

 list. Carrots and mangel-wurzels will in all 

 probability be the only roots planted in the field. 

 The former are excellent for horses, while man- 

 gel-wurzels will prove invaluable for winter 

 feeding in the dairy where there is no silo.
