This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1863 edition. Excerpt: ...soil permits, much deeper than the potato; it possesses, so to speak, a higher power of vegetation than the rye plant, and in the faculty of appropriating nutriment resembles weeds. 1853. Oats. Cunnersdorf, Miiusegast, Kotitz, Oberbobritzsch, Oberschona. The point which most strikes us in this table is the great inequality in the produce of two cereal plants grown successively on the same unmanured soil. The field at Cunnersdorf, which next to that at OberBchona had given the lowest crop of rye-corn and straw, yielded in the third year the largest produce of oat-corn and straw. The difference in the condition and closeness of the nutritive substances in the lower layers of these fields is undeniable. The field at Cunnersdorf was poorer in the upper layers, but went on increasing downwards in the amount of substances nutritive to the corn plant; the other fields decreased downwards. The returns of the field at Mausegast for the year 1853 refer to barley and not to oats: hence they afford no conclusion as to the condition of the deeper layers, from CLOVEK CKOP3 AND THE MINEBALS IN THE SOIL. 201 which the oat plant derives its food: but they show the state into which the arable surface soil had been brought by the preceding corn crop. Owing to the abstraction of phosphoric acid, and perhaps of nitrogen, the yield of barley-corn was much less than might have been expected from the soil, judging by the preceding rye crop; and a small supply of superphosphate or guano would have greatly increased the produce of barley on this field. Glover, 1854.--The clover crops in the fourth year afford an insight into the condition of the deepest layers from which plants draw their food. 1854. Clover.
