In this paper anthers investigated on colloid-chemical properties of field soils in Mikatagahara (Shizuoka). The results obtained are summarized as follows : 1. Electrophoretic velocity (u) of soil colloids from sub soil increase simply with the change of pH value, and the amounts of soluble aluminium from this soil increase remarkably in acidic solution, pH of which becomes smaller than 4.0. 2. Soil colloids of uncultivated soils have a mininum value of electrophoretic velocity at pH 5.8 ; and the same tendency of aluminium solubility is observed in top soils as well as in sub soils. 3. Soil colloids of well cultivated top soils have remarkable minimum point at pH 5.8 on the pH-u curve ; and amount of soluble aluminium is very small even at pH 3.6. These results indicate the cultivated top soils maintain stable equilibrium against the change of pH in natural environment ; and monotonous pH-u curve of sub soil indicate that the soil colloids are not stable against the change of pH and they have tendency of being hydrolyzed by derease of pH.

Mangese was detected in weeds belonging to 110 species referable to 37 families, with the following particulars : - 1) The Manganese contents differ considerably even in those of the same family, not to mention the inter family differences of the examined materials. 2) The substance in question is much more found in those weeds growing in acid soils. 3) It is also the case with those growing vigorously of those thick and juicy weeds. 4) It may be mentioned that the Manganese percentage against the total dry matter amounts to 0.124% in Polygonum Thunbergii Sieb. et Zucc, 0.102% in Equisetum arveuse L., and Plantago major L. var. asiatica Dence, and 0.1% in Houttuynia Thunb. These plants lead the list in Manganese contents.

In this report author described the influence of freezing and thawing action of volcanogenous soils on the properties of soil and growth of crops. (1) Influence of freezing and thawing action of volcanogenous soils are differ from the texture of soils. (2) On the volcanic ash soil, excess of water are accumulated from subsoil to surface, so when it melted, excess of water are flowed along to the topography of the earth accompanied with the small particles of the soil, namely soil erosion are occured. Moreover it can be guessed that in spring the drying of the farm are delaid, soil temperature are low, then the sprout of the seed are delaid, accordingly the growth of the young plant are very poor. (3) In the flowed water, it contained soluble nutrients of subsoil which lifted up accompanied with cappilary water, so if the soil erosion are repeated every year, it may be able to guess that surface and subsoils will become sterile by degree. (4) After thawing, soil texture are changed to platy or laminor structure, then the root of crops are developed rather horizontary in the surface soil than penetrats to the subsoil deeply, so the development of the root are poor, yield of the crops are obliged to decreaed. (5) In the frozen soil layer several ice pillar are formed especially near the surface, root of crops and grasses are killed at the point of the ice horizon, nursery trees are pulled up and falled on the surface soil. This phenomena become more obvious when frozen soil are melted. (6) Above mentioned phenomena of volcanic ash soil are true to volcanic sandy soil but it occured merely small scale and volcanic pumice soil are nothing influenced by the freezing and thawing action.

Availability of ammonium chloride supplied by crops was examined on several soils with regard to their ammonium fixing power. It was obserbed, in general, that rice or wheat plants were able to utilize more ammonium from a soil which has weaker fixing power than from the one with stronger fixing power. But a part of fixed ammonium was recovered by crops, and the degree of its availability was seemed to be depended upon natures of the fixing minerals.

This paper deals with the morphological, mechanical and chemical characteristics of the red soil formed over the terrace land of Koradai, near Kurume. The results obtained are as follows : 1. Main soil formers and profile characteristics of the soil are shown in Table 1. The soil consists of a thin, slightly dark-colored surface soil and a light brown subsurface soil followed by a compact red dish brown subsoil underlain by yellow sand. The lower part of the A horizon does not show any evidence of bleaching or fading, and the soil has a very slightly developed profile. 2. Mechanical and chemical characteristics of the soil are given in Table 2. According to heavily leaching process, the soil is very strongly acid in reaction and the degrees of base saturation are very low, i.e., about 7 per cent. The colloidal clays of the soil are more siallitic in composition than those of the red-yellow soils with same origin, found on the Pacific Coast of Central Japan. Their molecular ratios closely resemble those of the red soils derived from limestone and shale in Japan, and of the red soils of South China. 3. Exchange reactions (pH in water minus pH in 0.01 n Na_2SO_4) of the various horizons show neutrality or alkalinity. From this and other properties it may be considered that the soil is subjected to the anionic solvation and eluviation, and consequently, is not a product of podzolization. The soil is infertile because of the strongly acid reaction and the low base status.

By previous three reports, the authors announced modified SPURWAY'S methods were suitable, especially in the case of soil survey, for determining the amounts of easily soluble constiuents such as nitrate-N, ammonium-N, phosphoric acid and potassium, accompanied with exchangeable calcium. This time the authors tried to classify the above constituents in four degrees after their ammounts (designated as HH (very high), H (high), M (mediun) and L (low), each of the degrees having an approximate range of amounts (see Table). This classification may be available, when chemcal nature of soils in surveyed area are requred to be known.

Using the same samples as in the first report, analyses were made for determination of organic constituents, which are crude-protein, crude-cellulose, lignin and carbohydrate in the leaf-and-stem and the ear. The following results were obtained : 1) At the early stage of growth, protein is formed actively. After the ear-forming stage, much cellulose and lignin are formed and after the flowering stage, carbohydrate is formed in comparatively large amount. 2) Most part of the carbohydrate which is accumulated in the ear is a product of assimilation after the flowering stage. 3) Most part of the protein which is accumlated in the ear is what was reserved in the leaf-and-stem befor the flowering stage. 4) Cellulose and lignin seem to be only the frame-work of the field where the physiological phenomena are taking place.

The usual procedure for determining carbon in soil is to determine carbon by a wet combustion-method (i.e. Nogakukai's method) in our country This procedure is time-consuming and tedious, and requires a large space. A titration method which depends on measurement of K_2Cr_2O_7 or KMnO_4 reduced by the soil organic matter fails to estimate the accurate value of organic carbon in soil in spite of the simpleness of its procedure. In order to exclude such faults, an attempt was examined to establish a new method for determining carbon in soil after the method of Farrington et al. The results of soil analysis by the new method modified from that of Farrington et al satisfied approximately our purposes. The principle of this method is that a soil sample (corresponding to 1-10 mg C) is heated with Van Slyke-Folch's combustion solution in a stream of CO_2-free air, and the CO_2 evolved is absorbed in NaOH solution ; the carbonate thus formed is precipitated as Ba-carbonate and determined acidimetrically. The new method has the advantage of being more expeditious and economical than the usual wet combustion method.

Six wheat young plants were cultivated in each Wagner pot. On March 20th 1952,when wheat plant is in very-young-head forming period, one pot was manured with nitrogen and phoshate containing radioactive phosphorus and the other control pot was manured with only phosphate as is shown in Table 1. After 63 hours of top-dressing, 3 plants were sampled from each pot, dried in a steam oven, weighed, and then burnt in an electric furnace ; the ashes were disolved with HCl in stainless-steel counting cup, then dried under infrared lamp. Each cup was measured its radioactivity by Geiger-Muller counter. Datas shown in Table 2 suggest that nitrogen dressing followeb intense increase of the phosphate intake by wheat almost 5 times as that of control. After 80 hours of top-dressing, one plant from each pot was sampled, analyzed into each part carefully, and then dried by electric iron to pressed leaves. These pressed leaves were radioautographed as shown in Fig. 1 and 2. These radioautographs show that fertilized plant accumulated more radiophosphorus, and that. P^<32> was condensed especially in the very-young-head Two plants remained in each pot were grown to their ripening. On July 5th 1952,almost matured plants were sampled, devided into several organs, then dealt with the same method as above, mentioned to determine their radioactivities. From Table 3 and 4,we can estimate that paleass rachis, bootleaf, and nodes in fertilized plants have accumulat-ed two times or more of radiophorus as that of control at their matured stage.

The interest in the existence of various strains of rhizobia led the auther to a systematic study in that the classifying of rhizobia into species or subtypes on the basis of characters in artifical media is followed by the reexamimation on their behavior to legumes - the cross-inoculation, strain variation, and host specificity. In this part the results concerning the morphology of one hundred and three rhizobial strains isolated from various soils and legumes (twenty-nine genera) are described. Bacterial strains of lupine-group, Indigofera, Styphnolobium, and some of soybean and cowpea-group, show characteristic elongated forms on the yeast-water mannitol agar (five day's incubation at 28℃), whereas all others are observed as usual or small rod forms. Flagellation can hardly be used as a basis for classification, because any of the strains used is not found to be distinctly monotrichous.

Special precautions should be given to the handling of ultra-dilute solution of P^<32>O_4 and the determination of its intensity by plant ash as such. As revealed from Table I and Fig. 1,the absorption error of P^<32>O_4 on the surface of glassen ware sometimes oversteps the allowable limit of experimentation, when its contact proceeds at such ultradilution as is often the case in diluting H_3P^<32>O_4 sample of high specific activity. Practically, 0.5 p.p m. addition of inert PO_4 as carrier proved sufficient to minimise this reduction to negligible extent. Table 2,3,4 and Fig. 2,3,4,5 show the absorption effect of plant ash in the determination of P^<32> β-ray by Geiger-Muller Counter. Despite the powerful maximum energy of β-ray emitted from P^<32> (1.67 MeV.) self absorption of plant ash containing the same specific activity of P^<32> reached ca. 3% and 5% at 20 mg and 30 mg ash per square centimeters respectively.

(1) This paper deals with the serpentinization of amphibolite and the weathering of the serpentine derived from this amphibolite in Wakasa-machi, Tottori Prefecture (annual mean temperature 14℃, annual rainfall 1876 mm). (2) In the Serpentinization there are marked decrease of Si, Al, Ca, and alkali, and the increase of Mg and H_2O, in the weathering of serpentine Al and Fe increase, Mg decreases, and the following soils are formed : (I) dark green layer (below the subsoil) with coars granular structure, (II) redish-brown compact clayey subsoil, and (III) dark redish-brown clayey surface soil with granular structure and small humus (3.5%). (3) The Ni content of the amphibolite is 0.08% and it is increased to 0.14〜0.48% by serpentinization and weathering. Ni in the soils increases with depth. (4) In the early stage of weathering of serpentine the predominant clay mineral is halloysite, and with the progress of weathering kaolinite increases. The complex B consists of kaolinite, and the complex A_2 determined by the author's method consists of halloysite. (5) The free iron oxide in the dark green layer exists mainly in the form of limonite, and the iron of hematite form increases with the progress of weathering. (6) The serpentine soils are not rich in exchangeable bases but they have the high or moderate degree of saturation.

It is well known that the absorption of dye-stuff by the soil is always governed by the amout as well as the nature of colloidal part of the soil-Consequently, if the colloidal part is changed in its amount and also nature, the absorption of dye-stuff is expected to be changed in its degree and feature to an extent depending upon the nature of colloidal part. On this report the authors tried to trace the change of colloidal part, when heated in several degrees ; the change was being possibly expected to show the nature of colloidal part. Of three soils, different in their molecular ratios of alumina to silica (1-2<), the absorptive powers for dye stuff were determined by the use of photoelectric cell. More precisely written, the amount of dye-stuff absorbed by the soil was calculated from the transmittance-concentration courve (see Plate 1) obtained by the use of cobalt-coloured filter. The results were as shown in Table 3. From the results of Table 3,the following inclinations were observed. With the increase of heating temperature the absorptive power of the soils of higher ratio of SiO_2/Al_2O_3 (2<) decreased, while that of those of lower ratio increased. The above inclinations of quite opposite nature when compiled of the soils from genetic horizon of each soil type, are expected to become one of the suitable criteria for designation of each soil type. The following report of the same title will discuss the above designation.

The proteins, especially oryzenine, in white rice are increased about 10% or more by nitrogen application at heading. The nitrogen content of the bran layer is also increased, but the layer's thickness is not affected. Further the increase of lysine and threonine contents in white rice are seemed to be possible.
