COMPOST, is a mixture of manures, or 

 of earths and manures, in such propor- 

 tions, and of such qualities as are consi- 

 dered particularly applicable to the plant 

 or crops to which the composition is to 

 be applied. If leaves are required to be 

 largely developed, the compost can be 

 scarcely too rich ; for the greater the 

 quantity of food imbibed by the roots, 

 the greater will be the surface of leaves 

 requisite for its elaboration. But if 

 flowers and fruit, as well as leaves, are 

 desired, the composts, if excessively 

 rich, will cause these to diminish in 

 number and size, the flower -buds passing 

 into leaf-buds for the reason already al- 

 leged. 



Composts must also duly regulate the 

 amount of moisture supplied to the roots, 

 totally independent of drainage, as com- 

 post retains to them moisture by its che- 

 mical and capillary powers. The richer 

 in decomposing animal and vegetable 

 matter, and the looser its texture, the 

 better does a compost retain moisture. 

 And this power is diminished in propor- 

 tion as siliceous sand, or calcareous 

 (chalky) matters preponderate. 



Gardeners prepare their composts 

 from strong tenacious loam ; half rotten 

 leaf- mould; heath-soil; horse-manure; 

 cow-manure ; charcoal and wood-ashes ; 

 bone-dust ; sharp sand ; burnt turf ; and 

 moss well scalded ; and, from these ma- 

 terials, there is no doubt that a compost 

 could be prepared, embracing any de- 

 sired degree of fertility. See Manure* 

 and Potting.
