202 A PRACTICAL TREATISE ON MANURES. 



The stronger and the colder soils are, the more manure 

 they require; and, as such land is generally applied to the 

 production of crops which do not speedily attain their full 

 growth, the application of dung which has not been com- 

 pletely decomposed by the putrefactive process may be there 

 admitted; for although the progress of vegetation may not be 

 so rapidly forwarded, yet the manure will at length decay, and 

 afford a more gradual degree of nutriment to the present, and 

 greater support to the land for the production of future crops. 

 On adhesive land, long manure from the farm-yard also acting 

 mechanically, by keeping the soil open, is not so binding as 

 short dung; but on dry, sandy, hot soils, the dung should, on 

 the contrary, be perfectly decomposed, or rotten ; and manure 

 of any description should, on such land, be only laid on in 

 moderate quantities at one time. One general observation 

 may be made regarding all dissertations on manure, which 

 is — that as there will be different gradations both of soils and 

 the substance of which manures are composed, we can never 

 speak but in general terms of their application. 



The following table will explain how many heaps of ma- 

 nure — each containing an equal quantity of any given amount 

 — are required to dress any field, per acre, at certain regular 

 distances: so that, by calculating the solid contents of the 

 manure in cubical yards, each containing 27 bushels, and 

 dividing it by the number of heaps, the exact quantity to be 

 laid on in each heap may be correctly ascertained : —
