Chenopodiaceae), other varieties of which, under the name of mangold or mangel-wurzel, are grown as feeding roots for cattle.
The roots were grown under exactly the same cultivation and conditions as a crop of mangel-wurzel - that is to say, they had the ordinary cultivation and manuring of the usual root crops.
9,200 „ From the figures given previously of the amount of nitrogen, potash and phosphoric acid removed by a wheat or mangel crop it would appear that this soil has enough of these ingredients in it to yield many such crops; yet experience has shown that these crops cannot be grown on such a poor sandy soil unless manures containing phosphates, potash and nitrogen are added.
The area, however, under green crops - potatoes, turnips, mangel-wurzel, beet, cabbage, &c., shows during the same period a much less marked decline - only some 300,000 acres.
Since about 1885 the acreage under turnips has remained fairly stationary in the neighbourhood of 300,000 acres, while the cultivation of mangel-wurzel has considerably increased.
