Not illustrated. 1879 edition. Excerpt: ...in any of the necessary ingredients of plant food, which may easily be the case, when the potash and phosphoric acid have been too largely drawn upon. The recognition of a suitable soil for sugar beets presents greater difficulties than for many other plants, for they obtain most of their indispensable nutriment, by means of their long root, from the sub-soil, and the composition of this subsoil is therefore of immense importance. It is on this account that the experiments hitherto, with superficial manuring, have yielded no uniform results. We manure that portion of the soil, to be sure, from which the growing beet does long derive nourishment, but not that portion whence the plant obtains its food during the all important period of the formation of sugar. And the chemical means of sending the manures down into the sub-soil (viz: by admixture of chloride of sodium), are by no means so certain in their application that we can trust confidently that invariable results will follow every such experiment. On the other hand, and in perfect accord with this, deep 'plowing (subsoiling) has given the best and surest results in beet culture; and all observations upon the happy influence of the steam plow upon the beet crop, without exception (if we look at them in the proper.light), may be referred back to this cause, deep plowing. From this standpoint, those efforts which have for their aim the improving of the sub-soil by mechanical, as well as by chemical means, are the most important in beet cultivation. In other words, on one hand the deeper cultivation of the ground; on the other, the sub-soiling ' unter grunddungung, ' (manuring the subsoil.) Chemical analysis of that portion of the soil which we are accustomed to call the sub-soil (' acker-krum')...show more
