490 Field Experiments on Clover-Seeds, 



obtain a sufficient amount of ordinary dung at any price, and as 

 it may be wished to give the seeds a dressing, 1 woukl suggest 

 for trial the following mixtures, the components of which may be 

 purchased at an outlay of about 21. per acre : — 



For clover-seeds on light land : — ^'^^ ■'^°''^- 



£. s. d. 



2 cwts. of superphosphate, costing 12 



I5 cwt. of Peruvian guano, costing 1 



1 cwt. of muriate of potash, or instead, 2 cvvts. of crude 

 German potash-salts, costing 8s. to 10s. 



Total cost, 21. to 21. 2s. 



For seeds on heavy land I would suggest a trial with — 



£. s. d. 



2 cwts. of superphosphate, costing 12 



2 cwts. of nitrate of soda, costing 1 8 



Total cost, 21. 



For permanent pasture, I believe the following mixture will be 

 found both efficacious and economical : — 



s. d. 



1 cwt. of superphosphate, costing 6 



2 cwts. of bone-dust, costing 14 



1 cwt. of Peruvian guano, costing 13 



1 cwt. of muriate of potash, or instead of it, 2 cwts. of crude 



German potash-salts, costing 8s. to 10s. 



Total cost, 21. Is. to 21. 3s. 



If the land is in a poor condition, one-half more, or even 

 double the quantity, of the preceding materials should be used ; 

 for on exhausted pastures it appears to be better to give at once 

 a good dose of manure, whether natural or artificial, than to 

 fritter away money in the purchase of small and altogether in- 

 adequate supplies. 



Before sowing, the artificial manuring mixtures should be 

 diluted with as large a bulk of ashes as possible. With every 

 bushel of the artificials at least 3 bushels of red ashes or burnt 

 clay should be incorporated. If wood-ashes can be obtained at 

 a reasonable price, they will form an excellent addition to a 

 clover-manure. Coal-ashes are but a poor substitute for wood- 

 ashes or burnt clay ; however, in the absence of a better material, 

 they may be used for diluting the artificials. In conclusion, I 

 would suggest that the manures be applied to the land not later 

 than the middle of February.
