    In the previous report, author suggested that each definite leaf has its characteristic physiological function in relation to the formation of the rice plant body. In the present report, author describe some experiments undertaken to characterize the predominant function of leaves at any position on the stem of rice plant. For that purpose, leaf-blades at various positions on stem were cut off at various stages of growth and the influences of such treatments upon top length, weight of head, weight of leaf-and-stem, weight of 1,000 grains, number of tillers, number of ears per plant and number of grains per ear were examined. The following conclusions were obtained. The leaves (1/0-2/0) which emerged at seedling stage influence the power of revival from damage by transplantation, those (3/0-5/0) emerged at the time of recovering from damage by transplantation affect the number of tillering, those (6/0-9/0) emerged at tillering stage affect elongation of stem and formation of spikeletes and those (l0/0-12/0) emerged at elongating stage have influence upon the degree of ripening. In short, the growth of one stage is chiefly influenced by leaves which emerged in the previous stage and the leaves which are formed at any stage contribute to the growth of the next stage. In this way, rice plant develops phase by phase. Each organ, such as leaf-blade, leaf-sheath and stem, makes a different contribution to ear formation. Nitrogen which will enter into the constitution of the ear is predominantly stored in leaf-blade at flowering time and phosphorus is in stem. Considerable part of the potassium is already stored in ear at flowering but the larger part of it is absorbed after flowering.

    A number of soils varying rather widely in profile characteristics but believed to have developed from similar clay deposit were studied. Water soluble, exchangeable, easily reducible and hot HCI soluble Mn were determined. Changes in the nature and distribution of Mn in halogenetic polder clay soils, developed along the seacoast of Kojima Bay, during the process of soil development may occur in the following manner. 1. Generally, these soils contain a great deal of Mn. Immature soils, named younger and slightly leached halogenetic polder soils, do not show any variation in their Mn-contents and also forms throughout the profile. 2. Mature soils, named moderately and strongly leached soils, are leached to a greater degree, become more acidic, and have more clearly differentiated horizons. They show an accumulation of Mn, available and hot HCI soluble, in their second horizons. As leaching proceeds, Mn accumulates in the BG horizon more and more, while decreases gradually at other horizons. The data presented here show that there is apparently some movement of Mn within the soil profile and there seems to be the definite relation between the accumulation or leaching of Mn and the profile development of polder soils. 3. Four general types are found in the distribution of Mn, available and hot HCI soluble. The types are considered to be related to the soil development. Of the immature soils, named younger and slightly leached halogenetic polder soils : type I-little variation in Mn content within the profile type II-variation is found, but irregularily. Of the mature soils, named moderately and strongly leached halogenetic polder soils : type III-Mn increases slightly in the BG horizon type IV-Mn accumulates abundantly in BG horizon.

    Soil conditions have widely been studied as affecting physical properties of soil. The poly-organic acid properties of these material, however, might as well affect the chemical properties of soil, such as phosphoric acid fixation, ion exchange capacity etc. similar to humic acid. Five g of Tanashi volcanic ash soil preliminarily added with various amounts of Krilium 9 or 6 were shaken with 50 cc phosphate solution containing 25 mg P_2O_5 as K_2HPO_4 at various regulated pH. The fixation of phosphoric acid was determined by measuring the residual P_2O_5 in the solution. The application of Krilium 9 at comparatively low concentrations of 0.05〜0.2% was almost indifferent to or slightly promoted phosphate fixation possibly due to a slight lowering of pH (cf. Table 1 and Fig. 1). At comparatively higher concentrations of 0.3〜2.0% Krilium 6 and 9 evidently depressed the phosphate fixation compared at the same pH level as shown in Table 2,3 and Fig. 2,3. The addition of CaCO_3 prior to the application of Krilium almost did not alter the general trend (cf. Table 6 and Fig. 6). Sodium humate, which was prepared from pertinent soil, similarly and equally affected the phosphate fixation as Krilium as shown in Table 4,5 and Fig. 4,5. The mechanism was discussed on the basis of the acidoidal and complex froming properties of these materials. Further, it was suggested that the simultaneons band application of Krilium with fertilizers containing phosphate may be beneficial in promoting the phosphate availability.

    A typical highmoor peat profile of Ozegahara was analyzed for eight physical properties : apparent specific gravity, dry and wet (D_d and D_w), real specific gravity (D_R), contraction (C'), porosity (P), bulk density (volume weight D_v) volume weight of organic matter (D_<vo>) and water capacity (W); and relationships between those physical properties and KEPPELER'S degree of decomposition (K and K') were researched for. Eighteen samples were taken from the peat profile, (Table l) four of them, No. 8,9,13,14 had much ash, originated from volcanic ashes, two samples from the deepest horizons No. 1,2 which consisted of organic clay had also much ash. All of the physical properties had more or less correlation with the degree of decomposition, (Table 2), for instance, D_v, D_<vo> and C' of the above mentioned six samples were unusually higher. But, excluding those 6 samples, the degree of decomposition tended to become higher with the increase of depth, and physical property also had the same tendency. D_v and D_<vo>, however, did not show this tendency. Among the searched physical properties, apparent specific gravity, dry (D_d) and contraction (C') increased with the depth, and were considered to be the convenient criteria indicating the degree of decomposition.

    Concerning the components in A type humic acids isolated from several soils of different type, total-N, amino-N and non-hydrolyzable-N were determined, and the amino acids were also determined qualitatively by paper chromatography. The data were discussed comparing with each other and also with those of lignin isolated from rice-straw. The results are as follows : (1) The corresponding fractions of the A type humic acids from humus volcanic ash soil almost identical in the total nitrogen content. (2) With regard to the soils experimented considerable difference was observed between fractions in the total and amino-N content, which is almost in the following order viz., Fraction I>II>III. (3) The ratio of non-hydrolyzable-N to total-N is in the following order viz., Fracion I<II<III (IV). So the humification of each fraction seems to be taking place in such order as mentioned above even when viewed from nitrogen form. (4) The enrichment of nitrogen accompanied with the progress of humification is very feeble in humus volcanic ash soil. However, it is evident in black soil. Therefore the humification seems to be peculiar in the former soil and is different from that in the latter. (5) Fourteen kinds of amino acids were ascertained in the fractions of black soil, high moor peat and lignin from rice-straw, and fifteen kinds of them were detected in the fractions of humus volcanic ash soil and low moor peat. The difference in the number and kind of amino acid were not recognized between fractions separated from any soil used for the experiment.

    SPRINGER used in his earlier work acetyl bromide for separating true humic substnance from soil organic matter, but recently he proposed the use of mixed solution of acetic anhydride, glacial acetic acid and conc. sulphuric acid (Sulfacetolyseverfahren) instead of acetyl bromide. By the use of this solution we divided true humic substance into true humic acid and humin. 1) As the content of true humic acid did not differ significantly, we omitted the pretreatment of soils with acid. (See Table l) 2) Of upland soils, podsol had true humic acid very little; particularly, its A_0 horizon, which had a mor form. Degree of decomposition (Zersetzungsgrad) was beneath 20 in both horizons, B_1 and B_2; and humin was also very little. When we divided brown forest soils into two kinds, volcanic and non-volcanic, we could find great difference in the nature of the humus of the two. In the former, humus was accumulated; and the more the humus was, the larger the percentage of true humic acid was, we supposed, the humus in this accumulation was in the form of aluminate of true humic acid. The latter contained small amount of humus and its percentage of true humic acid was small. (See Table 2 and 3) 3) The amount of true humic acid in humic acid, extracted from soils by cold 0.5% NaOH, increased with the progress of humification. (See Table 5)
