The Supply of Potash. 



The most available supply of potash and the one from which the 

 least trouble can be expected, is in the use of unleached hard wood 

 ashes especially on a soil that is clayey and wet. I have found 

 ashes alone a splendid fertilizer at Mont Alto. Professor Johnson 

 suggests 30 pounds of freshly burned shell lime, 10 pounds of bone 

 meal and 8 pounds kainit a good substitute for wood ashes. This 

 formula is equal to 100 pounds of wood ashes. The ingredients can 

 be bought at the rate of $4.40 per ton ; hence, it is decidedly cheaper 

 and has no weed seed. 



Phosphoric Acid. 



Bone-meal containing three per cent, nitrogen and twenty per cent, 

 phosphoric acid, and kainit containing the same amount of phosphoric 

 acid, besides many other valuable plant essentials in small amounts, 

 are the two best sources of phosphoric acid to be had at a reason- 

 able price. 



Formulae for mixing fertilizers and composts are as follows : 



Composts. 



Substitute for wood ash equal to 100 pounds, 30 pounds freshly- 

 burnt shell lime, 10 pounds bone meal, and 5 pounds kainit. 



Thomas-meal, 16 per cent, citrates, 350 Ibs. 

 Slack lime, 2,650 Ibs. 

 Cornallite, 900 Ibs. 



Mix well together with fine turf, scatter over ground in late fall or 

 winter, and work well in early spring. 



Two measures of well rotted wood, two measures of well rotted horse 

 manure, one measure of liquid manure. Keep in covered place until 

 used. Even quantities of chip dirt and well rotted dung well mixed, 

 to which wood ashes and lime have been added. Keep two years. 



Ground bone, 300 Ibs. 



Bone black super phos., 300 Ibs. (Fall). 



Muriate of potash, 400 Ibs. 



Nitrate of soda, 89 Ibs. (Spring). 



Von Schroeder's: 

 Kainit, 520 Ibs. 

 Super phosphate, 60 Ibs. 

 Whale Guano, 320 Ibs. 



A good reliable fertilizer for general purposes, is: 

 Mixture of 30 pounds hen manure, 10 pounds sawdust, 16 pounds 

 acid phosphate, 8 pounds kainit.
