SEEDING DOWN WITH A TARE CROP 111 



generally the best for the purpose. By a complete 

 mixture is meant one containing the three dominant 

 ingredients of plant food, nitrogen, potash, and 

 phosphates. A suitable complete mixture for tares 

 would be: From 2 to 3 cwt. of superphosphate, 2 to 

 3 cwt. of kainit (when procurable), and from 1 to 1| 

 cwt. of sulphate of ammonia per statute acre. The 

 above may all be mixed together and sown at the 

 same time, although it is an advantage if the land 

 is in good heart to apply half the sulphate in autumn 

 and the other half in spring-time. 



On heavy land or on land deficient in lime from 

 3 to 4 cwt. of basic slag can be used in place of 

 superphosphate, and from 1 to 1J cwt. of nitrate of 

 soda in place of sulphate of ammonia. 



For spring tares on either lea land or after a corn 

 crop artificial manures prove very satisfactory. In 

 the general economy of the farm it is better to depend 

 on artificials for tares sown in spring, and to use 

 farmyard manure for other crops, or reserve it for 

 application in autumn the next time autumn tares 

 are to be sown. The mixture given above will form 

 a suitable mixture for spring tares also. 



TARES ON ROOT OR POTATO LAND 



After roots or potatoes which have been manured 

 with farmyard manure, no further application of any 

 fertilising matter, either natural or artificial, is 

 required until the following spring. Then the com- 

 plete mixture of artificials which is given above 

 should be applied. 



A farmer would not think of manuring a corn crop 

 which follows a manured root or potato crop, and 

 for this reason would be reluctant to manure a tare 

 crop which had been manured with dung in the
