In a quality district like Dibrugarh the use of real peat 

 bheel soil as manure should be perhaps avoided where other 

 materials are available, though, at present, there is no direct evidence 

 that it has a deteriorating effect. If applied, it should rather be put 

 on in the form of several small dressings than as a single large one. 

 The rich surface soil from the adjoining virgin land may, however, 

 .be applied with perfect safety. Cattle manure should be used if 

 available, but used sparingly and often, rather than heavily and 

 rarely. I would not put more than five tons per acre on such tea 

 land as the above in one year. In default of these methods, I should 

 advise with a good deal of confidence, the application of 5 to 7 

 cwt. of basic slag per acre in the cold weather (and use all the 

 wood ashes available in the same way at the same rate) with the 

 deep hoeing, and follow this by a green manuring crop in the 

 spring of mati kalai. The growth of this plant repeated every 

 three years, not necessarily with the addition of basic slag every 

 time, would improve the quality of the tea, A suitable rotation for 

 gardens under similar conditions would be : 



1st year - 

 with a crop of 

 2nd year 

 3rd year 

 4th year 

 5th year 

 6th year

Thus 

 as follows, 



Basic Slag 5 cwt. per acre in the cold weather, followed by green manuring 

 mail kalai in the spring. 

 -Nothing. 



Cattle manure in spring, 5 tons per acre, 

 Mati kalai in spring as before, as green manure. 

 Nothing. 



Oilcake 10 maunds per acre. 

 Nothin 

 Sulpha of Potash 2 cwt. per acre in April, followed by mati kalai as in 



Nothing. 



Cattle manure in spring, 5 tons per acre. 



Wood ashes 5 cwt. per acre, and mati kalai in spring as green manure, 



in ten years there would roughly be added to the land 

 per acre, from outside sources.
