LIQUID MANURE. 



IN a paper ' On Farmyard Manure and the Drainings of Dung- 

 heaps,' published in vol. xviii., of the R. A. Society's Journal, I 

 communicated the results of two experiments, which showed that 

 drainings from dung-heaps, in passing through soils of known 

 composition, undergo a series of remarkable and important 

 changes. Since the publication of this paper I have been 

 actively engaged in following up this interesting inquiry ; and, 

 at the request of the Council of the Royal Agricultural Society, 

 have now the pleasure of laying before the readers of the 

 Journal the results of my recent researches on the subject. 



The liquid manure employed in the following four experiments 

 contained in an imperial gallon : 



Grains. 

 Ammonia (in the state of carbonate and humate 



of ammonia) 35*58 



Organic matters 20*59 



Containing 1*49 of nitrogen. 

 Equal to 1-81 of ammonia. 



Inorganic matters (ash) 91'27 



Consisting of : 



Soluble silica 2*34 



Lime 11*48 



Magnesia 2*87 



Potash .;;.., .. .. 16*92 



Chloride of potassium 2*74 



Chloride of sodium 40*35 



Phosphoric acid 4*83 



Sulphuric acid 3*94 



Carbonic acid and loss 5*80 



147*44 



In the fifth experiment it was thought desirable to use a very 

 dilute fertilizing mixture ; and, consequently, liquid manure, 

 kindly supplied to me by Mr. Mechi, of Tiptree-hall, was 

 selected. The composition of this liquid manure will be stated 

 in a subsequent page.
