2. Trial of Nitrate of Soda. 



1839, July 12.— 1 cwt. per acre 

 upon lucerne, after the first mow- 

 ing, the first year. 



July 20.- — ] cwt. per acre upon 

 beet-root ; every alternate stetch 

 6 acres.' Hoed in with the second 

 hoeing. 



July 29.- — 1 cwt. per acre for 

 Swedish turnips; part after the 

 first, and some after the second 

 hoeing. 4 acres. 



July and August.- — 1 cwt. per 

 acre for white turnips, in every 

 stage of their growth after being 

 well up, before and after hoeing. 



1840, May 23.— 1 cwt. per acre 

 upon pease, 2 acres ; barley, 

 2 acres ; wheat, 2 acres. 



N.B. The white clover after the 

 barley failed where the nitrate was 

 used.

Benefit not equal to the cost, 

 and much inferior to the same cost 

 in soot, by which it was tested : the 

 soot at Sd. per bushel. 



Benefit not equivalent to the 

 cost ; scarcely apparent, except in 

 the colour of the leaves. 



The effect scarcely apparent ; 

 by no means equal to the cost. 



No benefit. 



Benefit not equivalent to the 

 cost, but the greatest upon the 

 barley. 



June 1. — Wheat, 2 acres; bar- The barley increased in quan- 

 ley, 10 acres. 1 cwt. an acre. tity equal to the cost, but layer 



not so good as where no soda was 

 sown; the wheat increased in 

 quantity, but not equal in quality. 

 I have since found that the layer 

 of white clover is almost destroyed. 

 N.B. In the above the experiments are made upon dry soils, with 

 sand, sandy loams, and crag subsoils, and the lands in the common 

 course of husbandry. The nitrate of soda 26^. per cwt. ; and expenses 

 of carriage and sowing 2s. per acre : and the experiments tested by very 

 close observation, but not in weight or measure.

3. Trials of Nitrate of Soda. By Charles Newman. 

 To the Secretary. 



Sir, — I am induced to ofi"er you a few observations and a statement 

 of the result of my experiments on nitrate of soda, as, though not exten- 

 sive, they may tend in some degree to confirm the interesting reports on 

 the same subject in the last and former numbers of the Society's
