A mixtiu-e of acid pliosphate and gypsnm is strongly recom- 

 mended by some, using them in about equal proportions. 



For average animals, the following amounts of different preser- 

 vatives may be used daily for each individual : 



KIND OF PRESERVATIVE. 



Gypsum (laud-plaster) 



Acid phosphate 



Kaiuit

When a mixture of superphosphate and gypsum is used, take 

 one-half or one-third of the amounts indicated above. One great 

 advantage in using acid phosphate or kainit is that one is adding to 

 the manure an important form of plant-food, in which the manure 

 is naturally deficient. The price at which one can get these mater- 

 ials must determine whether their use is economical or not. 



Mixture of different manures, such as cow and horse manures, 

 is advantageous, since one undergoes fermentation slowly and the 

 other rapidly. When mixed, the conditions of moisture are more 

 easily controlled. 



Whether stable-manure is stored in sheds, or in cellars or is pro- 

 tected in some other way, it is important to observe the following 

 precautious : (1) The manure should be spread out uniformly ; 

 (2) its interior should be protected against the access of air ; (3) it 

 should be kept always moist, but not too wet ; (4) it should be pro- 

 tected from sunshine ; (5) it should be protected from leaching ; 

 (6) some form of preservative should be used in the stables in addi- 

 tion to litter. 



Liquid and Solid Manure. — It is not an uncommon belief among 

 farmers that urine is worthless for fertilizing purposes, if we may 

 judge anything from the too general practice of allowing the liquid 

 excrements to run to waste through the barn floor. One has only 

 to glance at the composition of the solid and liquid excrements of 

 different animals as given below to see that the liquid is, in most 

 cases, very much more valuable than the solid portions. Not only are 

 the proportions of nitrogen and potash greater, as a rule, in the liquid 

 excrement than in the solid, but, as already noticed, the fertilizing 

 constituents of urine are entirely soluble and therefore more readily 

 available for plant-food than the constituents of solid excrements.
