CHAPTER VI. 



ON MANURES. 



To render the subject of the preceding chap- 

 ters as complete as possible, it is desirable that 

 the specific action of each individual manure 

 should be perfectly understood. Without a 

 full understanding on this point, it is impossi- 

 ble for the agriculturist to decide with a cer- 

 tainty of success on the manure for a certain 

 crop, or the best management to be adopted, 

 and although a keen habit of observation vt^ill 

 and does go far to supply this deficiency ; still 

 an explanation of the peculiar action of each 

 manure on the soil or crop, cannot but be use- 

 ful, to say the least : and, in the majority of 

 cases, such knowledge will be eminently ser- 

 viceable to determine the time proper for the 

 application of any particular substance, the 

 quantity to be used, and the best manner of 

 applying it. 



Having thus premised, it only remains to 

 say, that all substances, whether liquid or 

 solid, which are applied to the soil to promote 

 the growth and vegetation of plants, will be 

 considered as manure ; and although the sub- 

 joined list is far from containing all the mat- 

 ters thus made use of, still, a sufficient selec- 

 tion is given, from which the effects of others 

 not mentioned may be inferred.
