salt been mixed with the g:uano, there is reason to believe, from other trials, 

 that the grain would not have been deficient in weight per bushel. Ammonia- 

 cal salts should at no time be dressed upon grain crops, without, at tlie same 

 time, adding, according to the composition of the soil upon which such crops 

 axe grown, such other inorganic ingrediej^ as may be required. Few soils, at^ 

 least in this part of the country, appear ^fp to supply these in sufficiency to the 

 plants — particularly the phosphates, which seem always deficient. At least the 

 addition of bone-dust or animal charcoal seems always to improve the crops to 

 which they are applied. 



Experiment IV. — On Turnips. 

 Comparative eiFects of guano, farm-yard manure, bone-dust, and animal char- 

 coal, by themselves and in mixtures,' on Turnips of different varieties; lifted, 

 topped, tailed, and weighed, in Nov., 1843.

The field upon which the above turnips were grown is a light gravelly loam, 

 super-incumbent upon a deep gravelly till. The greater part of the field was 

 trenched with the spade, and all drained with tiles and soles 30 iriches deep and 

 20 feet apart, in the winter of 1841 and 1842, and in the preparation for the tur- 



• The animal charcoal here used is the refuse of the sugar refiners, and contains about 

 ilb. of its weight o{ bone-earth. 

 t This part of the field was trenched.
