MANURING EXPERIMENTS WITH PADDY RICE. 
37 
determining in the crop of No. i the amount of potash, in No. 2 
that of nitrogen, and in No. 3 that of phosphoric, we should be 
enabled to tell exactly how much of available nutrients exist 
in the soil experimented on and how much must be added in 
the manure. For the latter purpose it is, of course, necessary 
to know the rate to which the nitrogen and phosphoric acid 
of the various forms of manures is available to the rice in the 
ist, 2nd, and 3rd year. Researches which we intend to carry 
out in the coming season will help us to arrive at such a 
rational and solid basis for the manuring of the most important 
crop of this country.
