Potatoes. 



Dissolved bone-black, 300 



Muriate of potash, 150 



Sulphate of ammonia, 50 



500 



It will be observed that these combinations contain a consider- 

 able quantity of muriate of potash, and it must be borne in mind 

 that if seed comes in direct contact with them there is great 

 danger of the root being injured if not wholly destroyed. For 

 this reason I would especiall^^ recommend that a large part of the 

 fertilizer be used broadcast. The amounts above given are for 

 one acre when no manure is to be used. For corn and potatoes I 

 would never put more than one hundred and fifty pounds in or on 

 the hills or drills, and I would first plant and cover the seed as 

 though no fertilizer was to be used, and immediately after would 

 apply the one hundred and fifty pounds on the top of the hill or 

 drill, leaving it there to be washed down into the soil by the rains. 

 There is little if any loss in this method and I believe the results 

 will be better than from putting the fertilizer in the hill. 



Combination No. I, I would especiall}- recommend for corn, 

 IV for ensilage, and V for oats ; or as will be seen, it is so much 

 like I, that the same mixture may be used for either corn or oats. 

 However, if oats follow corn that has been manured with farm- 

 yard manure, it is not necessary to use nitrogen, and in such a 

 case I would recommend No. VI, or the potato mixture. No. IX, 

 ma}' be used. 



For ha}' two combinations are given ; the second is to be 

 recommended if four or five crops are wanted. 



For potatoes the same remarks as have been made concerning 

 oats will apply ; if the potatoes follow some crop that has been 

 manured with stable manure there is no need of nitrogen, and 

 therefore No. IX would be best ; in soils deficient in nitrogen No. 

 X might be best. 



It will be seen from what has been said that the corn combina- 

 tion I, may be used for corn, wheat, oats, and on some soils for 

 potatoes. The potato mixture, IX, may be used for potatoes and 

 oats on soils that have previously been manured, or are not defi- 

 cient in nitrogen. For ensilage No. JV is to be recommended.
