Book excerpt: Excerpt from The Rothamsted Memoirs on Agricultural Chemistry and Physiology, Vol. 7: Supplementary; Containing Reports of Field Experiments, Experiments on Vegetation, on the Feeding of Animals, &C., &C A large portion of the lecture on the conditions and results of growth of Leguminous Crops, which I gave' at the Colle e last year, was devoted to the illustration of the fact, that both t e scientific interest, and the practical value, of those crops, depended very much on the amount of nitrogen which they contain, and on the sources of their nitrogen; and especially on the great differences in these respects, between them and the representatives of the other families with which they are grown, either in alternation in our rotations, or in association in our meadows and pastures. I then discussed the bearing of existiu evidence on the question of the fixation of free nitrogen, and concludes by reference to some considerations and illustrations relating to the question of the sources of the nitrogen of crops generally.

Book excerpt: Excerpt from The Rothamsted Memoirs on Agricultural Chemistry and Physiology, Vol. 1: Containing Reports of Field Experiments, Experiments on Vegetation, &C., &C.; Published 1847-1863 Inclusive I certainly place great reliance on the experimental results which I possess; every operation has been conducted under the eye of Dr. Gilbert, a gentleman who received his scientific edu cation in the best British and continental laboratories, and has applied that accuracy which modern science demands, both to the operations Of the laboratory and the field. In the first place I shall Offer some general remarks upon the growth and nature Of the common agricultural plants, and after wards endeavour to show the effect of manures upon them.

Book excerpt: Excerpt from The Rothamsted Memoirs on Agricultural Chemistry and Physiology, Vol. 3: Containing Reports of Field Experiments, Experiment on Vegetation, &C., &C., Published 1863 1874 Inclusive In each case, the land was, in an agricultural sense, exhausted before the commencement of the experiment; that is to say, it would, in ordinary practice, have required manure before growing another crop. It is seen that, without manure, the two Graminaceous crops (wheat and barley) gave an average of about 24lbs. Nitrogen per acre per annum; the Leguminous crop (beans) nearly twice as much, or 47'81bs., and the mixed herbage of the meadow-hay, comprising both Graminaceous and Leguminous plants, 397lbs. Lastly, the turnips, with mineral, but without nitrogenous manure, gave 42lbs. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Thus, over the first period, the average amounts of soda in the total crop were, without any supply of either potash, soda, or magnesia, 840 lbs., and with the supply of all three, only 8'84 lbs.; over the second period, without the supply 15-21 lbs., and with the supply only 8-69 lbs.; and, lastly, over the third period, without the supply 11-85 lbs., and with the supply only 8-27 lbs. Thus, then, not only was there much more soda taken up, or retained, by the plant where it was not supplied than where it was, but it is evident that there was the more soda taken up the less the supply of potash. The amounts of soda retained in the grain are, however, seen to be but small; there is more, it is true, where there was a deficiency of potash, and where more soda was taken up. But, looking to the amounts of soda per cent, in the grain ash, or per 1000 dry substance of the grain, it would seem probable that the larger amounts where there was deficiency of potash, and more total soda taken up, were probably only due to larger amounts eliminated from the grain proper, and retained in the adherent paleae, or chaff. Whether, however, the soda has been of any avail, in the earlier, or merely vegetative stages of growth, as a carrier, or otherwise, may be a question..Next as to the phosphoric acid, of which there was the same annual supply on both plots. It is seen that whether we take its percentage in the ash, its proportion to the dry substance, or its average quantity per acre, the amounts are, in the comparable cases, comparatively uniform; the differences not being greater than can be supposed to be connected with the differences in growth due to the differences in the supply of other constituents. Lastly, as to...

Book excerpt: Excerpt from Rothamsted Memoirs on Agricultural Chemistry and Physiology (From the 'Philological Transactions'), Vol. 1: Containing Reports of Researches on Vegetation, Published 1861 and 1889 The facts at the present time generally accepted regarding the ultimate composition, and the sources Of the constituents, of plants, have, for the most part, received their preponderating weight of proof within the limits of the present century. But it is to the century preceding it that we must look for the establishment of much that was essential as the foundation of those advances which have since been made. Whatever may be the value at present attached to the particular views of hales regarding the composition and the sources of vegetable matter, we must accord to his labours, in the early part of the eighteenth century, the merit of having been guided by a proper Spirit Of experimental inquiry. Nor did he fail in applying to good account, and even in extending, the then existing knowledge of the material things around him which were apparently involved in the mysterious processes of vegetable growth.
