MANURES

Common Manures. 

 Analyses of cakes. 



Castor cake. — This is universally esteemed for the cultiva- 

 tion of the sugarcane crop to which it may be applied at a 

 rate of 1,000 to 2,000 lb. per acre. A common application in 

 Godavari is 10 bags of 164 lb. each, given in two applica- 

 tions. Its cost is about Rs. 80 per ton. As will be seen from 

 the analysis it is a general manure. It is known as black or 

 white cake according to the proportion of husk left in. 



Groundnut cake is not considered so good as castor cake 

 for canes, but is largely used for paddy in certam districts. 

 It is generally better to use it as food for cattle and return 

 its constituents to the soil in the shape of dung. 



Margosa cake made from the seed of the neem tree, 

 which is collected by women and children from under the 

 trees. The oil is used medicinally. The use of this cake 

 could probably be extended. 



Pungam cake used in many places where it can be 

 bought as cheap as Rs. 35 a ton. 



Fish manure {ordinary). Fish guano. 



Calophyllum Inophyllum.
