ONION. 105 



When discussing the amount of fertilizer to use on 

 vegetables, he said; "Put on all you think the land 

 can stand, then put on as much more, and you will 

 have about half enough." 



FERTILIZER FORMULA. 



Phosphoric acid, available ..... 6 per cent. 



Potash ................. .......... 9 per cent. 



Nitrogen ............ . ...... ... 5 per cent. 



Use a ton of this on land that is considered fertile 

 enough for an ordinary crop ; two tons may be applied 

 on land that has been cropped several years. 



AMOUNTS OF FERTILIZERS. 



Pounds. 



E/eiitt'nt. per acre. Pounds of different material for one acre. 



f 1600 to 3000 Ibs. cotton-seed meal ; or 

 | 700 to 1400 Ibs. nitrate of soda ; or 



Nitrogen... 10)-200 \ 1000 to 2000 Ibs. dried blood ; or 

 | 1400 to 2800 Ibs. guano ;* or 

 [ 500 to 1000 Ibs. sulphate of ammonia. 

 f 2200 to 4400 Ibs. kainit ; or 

 I 360 to 720 Ibs. muriate of potash ; or 



Potash ...... 180-3:30^ 350 to 700 Ibs. sulphate of potash; or 



| 700 to 1400 Ibs. sulphate of potash 



and sulphate of magnesia. 



Pho< aHd 190 940 / 120 to 240 lbs - acid Phosphate ; or 



120-.40 g dissolved bone 



SETTING OUT. 



The most expensive operation in the growing of 

 onions in this way is the setting out. This will be 

 found to cost about $40 an acre. Boys and girls will 

 set out 2,000 to 3,000 a day ; a good man can set 4,000 

 to 5,000, and as it takes about 160,000 plants to an 

 acre, it will be seen that it is no small job. It is 

 claimed by persons who have set out several acres 



*When guano is used as a source of nitrogen only two-thirds the 

 quantities given as a source of potash will be required, and only half 

 the quantities of phosphoric acid. This is due to the fact that guano 

 contains a large amount of potash and phosphoric acid.
