THE APPLICATION OF LIME IN AGRICULTURAL 
PRACTICE, WITH PARTICULAR REFERENCE 
TO PARA RUBBER TREES. 
By B. J. Eaton, f.i.c., f.c.s., Agricultural Chemist, F.M.S. 
Considerable interest is now being taken by planters in the 
Federated Malay States in the subject of manuring, and requests for 
soil analyses and advice re-manuring are being constantly received 
by the Department of Agriculture, F.M.S. 
A number of enquiries has been received asking particularly for 
advice re-lime, its method of application, and the benefits to be derived 
from it, in consequence of which it has been thought advisable to pub- 
lish this article, which, although it makes no claim to originality, it is 
hoped will explain the value of lime as a factor in agriculture. 
Soils of the Federated Malay States. 
In general it may be stated that soils in this country are deficient 
in the essential mineral constituents, viz., lime, phosphates and 
potash and as a rule contain fairly large quantities of nitrogen, 
especially where the land has previously been under virgin jungle.
