The manurial value of seaweed

Seaweed is essentially a potassie fertilizer, being specially rich in potash, but it also contains notable amounts of nitrogen and other elements of plant food, so that it might be terined a complete manner.

Fresh seaweed in undoubtedly a watery manure, containing from 65 to 90 percent of water and it is this fact, no doubt, (the cartage being a more or less expensive feature) that limits its use to those living more or less close to the shore. A part of this useless water may be got rid of by drying the seaweed on the beach for a few days before hauling to the farm. But not withstanding its large percentage of water, seaweed compares quite favourably, weight for weight, with barnyarnd manure, and it has this advantage that it brings to the farm no weed seeds nor insects nor fungus pests. 

Analyses of many Canadian seaweeds, more especially from the Atlantic seaboard, have been made in the Experimental Farm laboratory in Ottawa, and we append in tabular form certain of the data as illustrative of their general composition.
