Liquid Manure, 



unvaried success by Professor Schiibler^ and the results may be 

 stated in the following order. 



If the soil, without any manure^ yield a produce of three times 

 the quantity of seed originally sown, then the same quantity of 

 land will produce — 



5 times the quantity of seed sown^ when dressed with old 



herbage, grass, leaves, &c. 

 7 times, when dressed with cow dung. 

 9 times, with pigeons' dung. 

 10 times, with horse dung. 

 12 times, with human urine. 

 12 times, with sheep's dung. 



14 times, with human manure, or hidlocW blood. 



Thus, it will be seen, that, of seven usually employed fertilizers, 

 the liquid manures, urine and blood, were found to be decidedly 

 the most powerful. 



Both with regard to the quantity of liquid manure applied per 

 acre, and the mode of spreading it, much must depend upon the 

 circumstances under which the cultivator is placed, and the rich- 

 ness of the liquid he employs. If the impurities dissolved, or me- 

 chanically suspended in the water, are equal to 1 part in 10, 

 then 20 to 30 tons per acre of the liquid manure I have found 

 amply sufficient, under ordinary circumstances, to produce the 

 most excellent results ; if the fluid mass is purer, then more must 

 be applied. For gardens, and small plots of ground in general, 

 the liquid may be readily and evenly distributed over the beds by 

 means of a watering-pot or garden-engine ; for fields it must be 

 carried in water-carts, and distributed either by being let into a 

 transverse trough, pierced with holes in the manner of those em- 

 ployed for street- waterings, or the Flemish plan may be adopted, 

 (especially when the manure is of too considerable a thickness to 

 flow readily through holes) of taking it into the fields in the water- 

 carts, open at the top, (furnished with slight moveable covers,) 

 and then distributing it out of the cart very evenly by means of 

 a scoop ; and I have invariably perceived the advantage of plough- 

 ing the liquid into the soil as soon after it ivas sjoread on the 

 land as possible. The cultivator will find great advantage if he 

 uses the garden- engine, watering-pot, or cart, from straining the 

 liquid manure, before he pumps it out of the reservoir, either 

 through straw, coarse sand, or a basket; the pieces of straw, and 

 other coarsely divided-matters thus separated by the strainer, he 

 will discover add very slightly to the fertilizing powers of the 

 liquid, and yet they all materially hinder the even distribution of 

 the manure.
