Page 271 - But, to suppose that whole wheat ineal, as ordinarily prepared, is, as has generally been assumed, weight for weight, more nutritious than ordinary bread-flour, is an utter fallacy, founded on theoretical text-book dicta : not only entirely unsupported by experience, but inconsistent with it.

To the same trustees he covenanted to pay the sum of £100,000, the interest on which was to be applied to the maintenance of .agricultural investigations under the direction of a Committee of nine persons, of whom four were to be nominated by the Royal Society, two by the Royal Agricultural Society, one by the Linnean Society, and one by the Chemical Society, the owner of Rothamsted being always a member...

The circular issued states : " It was considered that Mr. Lawes has for many years been engaged in a series of scientific and disinterested investigations for the improvement of agriculture generally, which...
Page 24 - The soil upon which my experiments were tried consists of rather a heavy loam resting upon chalk, capable of producing good wheat when well manured; not sufficiently heavy for beans, but too heavy for good turnips or barley. The average produce of wheat in the neighbourhood is said to be less than 22 bushels per acre, wheat being grown once in five years. The rent varies from 20s. to 26s. per acre, tithe free.
Page 95 - ... amounts of produce are throughout on a lower level. This can only in part be attributed to the exclusion of potash from the manures. It is doubtless mainly due to the incidental circumstance that in growing the same description of crop, with the same comparatively limited and superficial root-range, for so many years in succession, the surface soil became less easily worked, and the tilth, so important for turnips, was frequently unsatisfactory ; whilst for want of variety and depth of root-range...

I shall confine attention to the amounts of produce reckoned as hay, and to the estimated amounts of nitrogen in the produce. It should be stated that, as the garden-clover plot is only a few yards square, calculations of produce per acre can only give approximations to the truth ; but it is believed that they can be thoroughly relied upon so far as their general indications...
