SEAWEED AS A FERTILISER
It is an odd faC-t that, although wo are nn island people largely dependent upon imported fertilisers and are at tho moment menaced by the high cost of plant foods of every description, we do not moke fuller use of seaweed. Our coasts, estuaries and tidal rivers yield vast quantities of this weed. Its valuo os a fertiliser is indisputable, yet it is only in comparatively limited areas that practical use is mado of it by land cultivators. Many potato-growers in the west of Scotland, the -farmers and gardeners of the sea margins of tho southwestern English counties, and the intensive cultivators of tho Channel Islands to a great extent rely upon this driftweed for the fertilisation of the bulk of their crops. But, with these exceptions, it may safely.be said that over tho whole of the remainder of the'eountry the use of seaweed as manure is non-existent. The chief elements of value in seaweed, from our point of view, aro nitrogen and potash. It is aa rich in the former as farmyard manure, and when decayed in the soil those ammonia compounds very soon becnw available.—"Farmers' Union Advocate."
