Tomato plants (Lycopersicon esculentum Mill. cvs. Momotaro and Yuyake) were grown under 2 irrigation regimes (high and low water stress) and 3 amounts of bark compost application (0, 5, 10kg m^<-2>) under root-zone restriction by placing root-proof sheets 25 cm below the soil surface. Highly soluble solid fruit juice contents (10-12%) were obtained from root restriction. The soluble solid contents were not affected by compost rates but fructose and glucose contents increased with the amount of compost application. The ratio of total sugar content to soluble solid content was higher in the plots to which compost was applied. Neither the number of tomatoes per plant nor the mean fresh weight was affected by the irrigation regime or amount of compost, but the incidence of blossom-end rot decreased with as the amount of compost applied increased, resulting in a higher yield of normal fruit. The fruit diameter expansion rate generally reached a maximum 8-12 d after anthesis. The application of compost reduced the fruit growth rate and hence delayed the time when maximum fruit growth rate was reached. The nitrogen concentration in plants an fruit was reduced but the Ca concentration in the distal half of fruit increased upon application of compost. These results indicate that application of compost reduces the incidence of blossom-end rot by reducing the uptake of nitrogen and slowing down the fruit growth rate.

The possibility of potassium appication on grassland in Andosol for low-input sustainable agriculture is discussed. The application of 300 kg ha^<-1> y^<-1> of potassium as an exchangeable fertilizer in 0-5 cm soil has been rcommended to maintain high dry matteryield. Eighty out of 300 kg ha^<-1> of exchangeable potassium has been required since 220 kg ha^<-1> y^<-1> of potassium as fertilizer is needed in Hokkaido. In this study, a potassium application test was carried out on a timothy-legume mixture in the Konsen district in order to estimate the feasibility of reduced potassium application. The amount of potassium required to maintain a stable legume ratio, which is important in maintaining grasslands over the nolg term, was less than that for high dry matter yield. Reduced potassium application made the potassium content of forage lower, the calcium and magnesium content higher, and as a result, the mineral balance of forage better although it decreased dry matter yield. Eighty kg ha^<-1> of Potassium in 0-5 cm soil could not be maintained because of uptake by timothy. Moreover, the amount of exchangeable potassium in autumn decreased until the next spring.It is important to estimate the minimum application of potassium for a stabl legume ratio, and to clarify the amount of exchangeable potassium in the soil for stable fertility and conservation of the environment. Potassium applicaion is expected to be reduced on the bsis of the results of these experiments.

A colorimetric method with ascorbic acid powder and a mixed solution (ammonium molybdatehydrochloric acid) was developed to determine the acetate buffer-soluble silicic acid content in soil testing. This method is superior to the IMAIZUMI・YOSIDA method in terms of stability of color and high sensitivity, and moreover the calibration curve is linear up to 75 mg L^<-1> of SiO_2. 1) The newly developed analytical procdure is as follows. Place 0.5 mL of sample solution in a test tube. Add 4.5 mL of distilled water and 0.5 mL of the mixed solution, and allow the mixture to stand for 20 min. Then add 0.5 mL of 400 gL^<-1> tartaric acid solution and allow the tube to stand for 3 min. Add one spoonful (45 mg) of ascorbic acid powder with a small spoonful of Zen-Nohreagent. Measure absorbance at 810 nm between 5 min and 5 h later. 2) Maximum concentrations of phosphoric acid, ferrous iron and ferric iron in the extracts of 48 soil samples were 41 mg L^<-1> of P_2O_5, 2.9 mg L^<-1> of Fe^<2+> and 86 mg L^<-1> of Fe^<3+> respectively. Therefore no interference by these ions was observed in this method. Low coefficients of variation of from 2% to 4% were obtained in 12 replicate determinations using this method. 3) The contents of acetate buffer-soluble silicic acid determined using this method agreed well with those determined using the ICP method. In this method, high calcium contents in soil samples did not interfere with the determination of the available silicic acid content.

In the present paper, the chemical forms of Zn, Mn and Cu in soils of Sugadaira-Kougen were studied in detail using a sequential extraction method. The results obtained are summarized as follows. 1) The Zn content in the residual fraction of soils was 60-90% of the total Zn. The percentage of Zn in the organic matter fraction could be arranged in the order upland>grassland>forest (bareland) soil. The percentage of Zn in the exchangeable fraction was less than 3%. 2) About 50% of Mn was present in the residual fraction but the percentage of the Fe oxide fraction was 30-65% in the forest (bare land) soils, and was more than two times higher than in the upland or grassland soils. There was a significant correlation between the Mn concentration of the organic matter fraction and the total carbon content in each soil (γ=0.87^<**> n=11). The Mn value in the exchangeable fraction was 5-9% lower than that in each fraction. 3) In the case of the forms of copper, the percentage of the organic matter fraction was high in upland soils but that of the residual fraction was the highest in the forest (bare land)soil. The mean value of Cu associated with the organic matter fraction was 40% in the upland soils and about 25% in the grassland soil, but it could not be estimated in the forest (bare land) soils. The Cu percentage of 0.5% in the exchangeable fraction was consistently lower in each regime.

On september 13, 1982, aogare (wilt disease) occurred in the northern part of the Kanto Region right after typhoon No.18 had passed. The damage extended over 3, 700 ha of paddy rice in the northern area of Saitama Prefecture. To investigate the actual conditions of damage and its cause in these areas, such as meteorological factor, fertilizing practices on paddy fields, and nutritional and physiological conditions of different varieties of paddy rice were studied. The results are summarized as follows : 1) The day was bright with high temperature of 28℃, wind speed of 6.0m s^<-1> minimum humidity 36% at 9:00 AM on the 13th ; at 15:00 the ground surface was dehydrated and acute dehydration disease occurred in paddy rice. 2) Aogare occurred about 2-30 d after heading. The physiological symptoms were partly attributed to high levels of total nitrogen application (more than 130 kg ha^<-1>) especially in the later growth stage. Thus rice yield decreased below 1, 500 kg, ha^<-1>. 3) The average of physical and chemical values of the soil in the aogare area, which decreased less than in other areas, were as follow : the depth of the plow layer was 10.4 cm ; soil hadness exceeded 2.0 MPa ; hydraulic conductivity was 10^<-6>-10^<-9> m s^<-1>. These areas obviously had compaction, and adverse effects on the soil environment were also found. 4) The photosynthate content of starch and sugars in the leaf sheath plus culm tended to be lower in the aogare paddy rice. The carbohydrate content in the stem was less than 14% in the aogare plants. 5) The potassium and silicon contents in the straw (leaves plus culm) of aogare rice were reduced. The carbohydrate content of the culm decreased to the minimum level 20-30 d after heading. This was also confirmed by the starch iodine test. 6) The basic factors in aogare is thought to be related to nutrient conditions during the ripping stage, climatic conditions, the amount of nitrogen application, and changes in the soil environment in recent years.

A pot experiment was carried out in order to investigate the effect of inoculation of three arbuscular mycorrhizal fungus, Glomus mosseae GERDEMANN & TRAPPE, Glomus caledonium TRAPPE & GERDEMANN and Glomus fasciculatum WALKER and KOSKE and the application of phosphate on phosphorus uptake and growth o Welsh onion (Allium fistulosum L.) in Andosol. The arbuscular mycorrhizal infection rate, phosphorus concentration, and dry weght of shoots were determind. The infection rate with arbuscular mycorrhizal fungi was higher in plants inoculated with G. fasciculatum than those inoculated with other fungi at all P levels (0 (P0), 218(P1) and 436 (P2) mg P pot^<-1>). Infection was highest at the P0 level and decreased with phosphate application to soil. The P concentration in shoots was higher in plants inoculated with G. fasciculatum than in those inoculated with other fungi or in plants without fungi at all P levels. The shoot dry weight was higher inplants in oculated with G. fasciculatum than in those inoculated with other fungi at all P levels. The shoot dry weight of plants inoculated with G. fasciculatum at the P1 level was similar to that of non-inoculated plants at the P2 level. It is suggested thet selection of suitable fungal species and optimal phosphate application are important for improvement of growth using arbuscular mycorrhiza, because species differences in the rate of infection, increase P uptake, and growth have been observd at each P level.

The contribution of Zn in activated sludge applied to Andosol as a fertilizer to increased Zn concentrations of plants grown in the soil was estimated. At the same time, the effect of added Zn on Cu and Mn concentrations in the plants and soil was examined. We prepared three types of activated sludge with different levels of Zn concentration taken from municipal wastewater with an elevated Zn concentration. The application of the activated sludge to the soil increased the AB-DTPA soluble fraction of soil Zn and the Zn concentration of plants (Brassica rapa L. var. pervidis Bailey) grown on the amended soil in a greenhouse. The increase in plant Zn concentration and the amount of soluble Zn in the amended soil correlated closely. This indicates that Zn in the activated sludge was easily takn up by plants and also that plants absorbed Zn mainly from the sludge. Zn concentrations in plants decreased as the incubation period of the soil before sowing was extended. This suggests that Zn in the sludge was transformed into a form less available to plants, although it was still AB-DTPA soluble, by decomposition of the activated sludge. The higher concentration of Zn in the sludge did not affect the concentration of Cu and Mn in the soluble fraction from the soil and in the plants.
