On the other hand Schlossing found as mmli 
as '8 per cent of ammonia in Havanna tobacco. 
The mineral ingre<lient which seems most to 
affect the (|uality of the tobacco is iiotash 
combined with an oiganic acid; but vliich in 
an analysis of tiic ash ajipears as c;trbonale of 
potash. As a gcncial rule a toliacco, the ash 
of which is rich in carbonate of jiotasli burns well. 
Nessler illustrates this by the following tabic : —

The above are from Haldanc's " Subtrojiical 
Cultivation Climates," the author of wliich says 
"the best aititiciiil maniirps will be found to be 
(1) Carbonate of ])otasli, or pearl ash. 
(2) Siiljdiate of jiota.sli costing from £12 to 
£•20 per ton. 
(3) Nitrate of potash, or saltpetre. Applied 
at the rate of 2 cwts. per acre. 
The kind of soil suitable for tobacco is evidently 
very varied, and practical planters are sai«l to 
pay more regard to the mechanical condition 
than to the chemical composition of the soil. 
Thus there appears to be a consensus of opinion 
that liea\y clay land is unsuitable, and that free 
well-drained soils are best. The conclusions that 
Schlossing diew from v.arious experiments to 
ascertain the kind of soils best suited to produce 
fine tobacco w ere these. " He found that a 
bad burning toljacco was produced in a soil 
containing little ]iotash, on unmanured soil, on 
soil manured with Hesli, humus, with calcium 
chloride, magiiesiiiiii chloride, and ])otassiuin 
chloride" a good Inirniiig tobacco was prodnceil 
on a soil manured with ))otassiunj carbonate 
with ealtjietie, and Mitli j)ottt.^;iium sulfate,'"' '
