has been found to give good result in the Nagpur experiment- 

 al farm also, and this system therefore is to be preferred. 

 Indian cattle dung and urine (specially the latter) are not 

 poorer than English cattle dung and urine, as the following 

 results of analyses given by Dr. Voelcker will show : 



844. In i ton of farmyard manure there are 9 to 15 Ibs. 

 of N, 4 to 10 Ibs. of P 2 Os and 5 to 13 Ibs. of K 2 O. Manure 

 made in boxes contains twice as much nitrogen (18 to 30 Ibs. 

 per ton). Rotten dung is more soluble and is a better manure 

 than fresh dung, but it contains little free NH 3 which is" 

 combined with vegetable acids. During fermentation dung 

 loses H 2 O, CO 2 , CH 4 , H and N which are evolved in the 

 process and thus it becomes more concentrated. Very little 

 NH 3 is lost unless it is allowed to wash away. Dung which 

 is not pitted but kept spread out loses two-thirds of its N; 

 in pits or heaps, only a third of the nitrogen is lost, but when 

 the pit is covered it loses only 10 per cent, of N.
