KoO Fig. 15.—Showing the ratios of P20i, NUa, and 1\;20 in the original solutions, those in the solutions aftergrowth, and those of the loss from the culture solutions, with dihydroxystearic acid—Experiment II. 44 EFFECTS OF A HARMFUL SOIL CONSTITUENT. The ratios of the constituents P2O5, NHg, and K2O, in the originalsolutions, those of the materials removed during plant growth,and those of the materials remaining in the solutions, are indicatedin figures 21 and 22. The diagrams show in general the same trendin the results as is exhibited in the diagram for the preceding experi-ment, except that when the dihydroxj^stearic acid is present, theradiation from any special area is not so marked, and the displacementof this area toward the nitrate angle, as was the case in the two pre-vious experiments, is not so apparent, although a shifting of nearlyall of the lines in that direction is noticeable.
