    In experiment 1, the following two treatments were examined in order to evaluate the adaptability to masa-soil of the digestion sludge of methane fermentation ; one is to saturate ammonium fixation ability of masa-soil by supplying enough NH_4^+ to it before cultivation (pretreatment plot); the other is not to do so (no pretreatment plot). In the pretreatment plot, tomato plants showed strong ammonium toxicity symptoms. It was judged that the reason was that the NH_4^+ concentration in the soil became high when NH_4^+ was supplied in excess of the ammonium fixation ability of masa-soil. In the no pretreatment plot, ammonium toxicity symptoms were slightly reduced. The ammonium fixation ability of masa-soil was not saturated even if the application of digestion sludge was continued for the whole growing period. Therefore applied NH_4^+ was fixed to the soil, and absorption of NH_4^+ by tomato plants was restrained. However, it can be understood that the reduction effect of ammonium toxicity symptoms was small because of applied NH_4^+ not having carried out nitrification. In experiment 2, the field soil was compared with masa-soil in terms of the growth and yield of tomato plants. In this experiment, two acids were used in order to adjust the pH of the digestion sludge ; one was nitric acid (nitric treatment) ; the other was sulfuric acid (sulfuric treatment). The growth and yield of tomato plants in the field soil was better than those in masa-soil because the ammonium toxicity symptoms considerably declined with the progress of nitrification. In the field soil, the yield for the nitric treatment was equal to that in the control plot. However, the yield in the sulfuric treatment fell slightly because the ammonium toxicity symptoms were severe at harvest time. From the above results, we see the possibility of using the digestion sludge of methane fermentation as liquid fertilizer in the field soil by using nitric acid in order to adjust its pH.

    On the hypothesis that a crop uptakes a certain rate of available nitrogen in the soil, we developed a model for the analysis of the N (nitrogen) flow in the national food supply system combined with the soil N budget of the cropland in Japan. Using the model, the amount of N applied to soil in the recycled use of organic waste from the home and industry sector (recycled N) for crop nutrition was calculated to be 366, 418, 490, and 482 in Gg N for the years 1982, 1985, 1992, and 1997, respectively. The outflow of N from cropland was calculated as 491, 513, 499, and 458 in Gg N for those respective years, showing a little decrease in 1997 owing to the rapid reduction in the application of N by chemical fertilizer (chemical N). The total estimated load to the environment by the national food supply system was 1823, 1981, 1941, and 1862 in Gg N for the investigated years, which reflects the decrease of the outflow from cropland. In the case of all the food and foodstuff being imported, the total load to the environment reaches a minimum in the calculation without N outflow from the cropland. We found that by increasing the rate of recycled N in the total N supply for crop production (chemical N+recycled N) to the level of 68-69%, the total load to the environment reaches the minimum even if domestic crop production is sustained at the same level as in each investigated year. It gives a goal for environmentally friendly soil fertilization in modern Japanese agriculture. In the case of decreasing 10% of chemical N by increasing the rate of crop uptake of N from 0.5 to 0.52-0.53, the total load to the environment is lowered by 2.5-3.5% compared with the investigated value of each year. In the case of decreasing the same amount of chemical N and replacing it by increasing the use of recycled N, the total load to the environment is lowered by 3.5% each year in the same comparison. Increasing the domestic crop production, e.g. rice planting for silage in the vacant paddy field, can lower the load to the environment if the nutrition for increased crop production is supplied by the additive use of recycled N.

    We investigated the effect of the basal application method, a single application of fertilizer in a nursery box (SAF) and the whole layer application of fertilizer (WAF) on weed growth and nutrient uptake in a lysimeter paddy field of Gray Lowland soil. The amount of ammonium nitrogen in the plow layer of the interrow space was higher in the WAF plot than in the SAF plot. The SAF restrained the dry matter of weeds as compared with the WAF. This tendency was more pronounced year by year. The dry matter of weeds in the SAF plot was lower than that of the WAF plot in the 3rd year of rotational paddy field. Barnyard grass (Echinochloa oryzicola Vasing.) accounted for over 98% of the WAF plot and about 77% of the SAF plot in terms of dry matter. The tiller number of rice was the lowest under the unweeded control in the WAF plot. The relative light intensity was lower at all heights under the unweeded control in the WAF plot compared with that under hand weeding. The amount of nutrient uptake of rice under the unweeded control in the WAF plot was greatly restrained compared with that under the unweeded control in the SAF plot. The amount of nutrient uptake of weeds was lower in the SAF plot than in the WAF plot. Barnyard grass (Echinochloa oryzicola Vasing.) accounted for most of the nutrient uptake of the WAF plot. The rice yield in the unweeded WAF was significantly influenced by weeds, and was 16% of that of hand weeding due to the decrease in number of grains per unit area and thousand grain weight. The rice yield in the unweeded SAF plot was 83% of that of hand weeding. The rate of grain yield (unweeded control/hand weeding) was higher in the SAF plot than in the WAF plot. These results suggested that a single application of fertilizer in a nursery box in a rotational paddy field decreased weed growth and maintained rice yield.

    It is important to appropriately maintain the nutritional condition of the tree in order to stably produce apples with high quality. To appropriately maintain the nutritional condition of the tree, technology that appropriately evaluates the nutritional condition of tree is necessary. In order to enable the simple evaluation of the nitrogen nutrition condition in the production field, the authors devised a technique which evaluates the nitrogen nutrition condition from the value which digitizes the overgrowth of the foliage by image analysis. It was confirmed that the technique was effective as a simple evaluation method of the nitrogen nutrition condition of apple trees. In addition, the value is closely related to the yield and quality of the fruit. So, it seemed to be possible to set the standard value of this value as a goal for ensuring the yield and quality of the fruit.

    In drip-application (fertigation) culture, plant nutrients are supplied both from nutrient solution and from soil media. In this study, we examine the adequate supply of bases for tomato (Lycopersicon esculentum) and melon (Cucumis melo), considering the base status in the soil and by adjusting the solution compositions. 1) Even if magnesium and calcium were not added to the nutrient solution, tomato (in the fifth cluster stage culture) yield and the absorption of both elements were almost the same ; the fact suggested a sufficient supply from the soil. 2) The concentration and composition of bases in the soil solution was different from that of bases in the nutrient solution because of the supply of bases from the soil. The amount of calcium supplied from soil was larger than that of magnesium, and that of magnesium was larger than that of potassium, so it is considered that potassium is indispensable for nutrient solution, and calcium isn't needed as much for nutrient solution. It seems that magnesium supply from nutrient solution is sometimes effective, especially in the later stage of cultivation. 3) With the soils in which the nutrients are enriched as there are in most farmers' greenhouse soils, we can achieve the adequate growth of tomato (in the fifth cluster stage culture) and melon (one fruit per plant) by using nutrient solutions based mainly on nitrogen, potassium and magnesium, avoiding the unnecessary accumulation of the nutrients in the soils. 4) As to the nutritional diagnosis by the base concentration in the petiole sap, the potassium concentration reflected the potassium status in the plant very well. Magnesium and calcium concentrations were affected very antagonistically by the potassium status in the plant.

    The effects of the moisture content and bulk density of soils and the addition of dried swine feces on denitrification in upland soils were investigated in a laboratory experiment using an acetylene inhibition technique. Low-humic Andsols (LHA) or Gray Lowland Soils (GLS) were used in the experiment with or without adding dried swine feces at four levels of moisture content. In addition, soil columns were prepared by packing each soil so that the bulk density of them was adjusted to four different levels. Denitrification rates of the soil columns prepared were determined at 25℃ during 4 days. We also determined the in situ denitrification rate of two upland soils (LHA, GLS) receiving dried swine feces during the growing season of maize by the combination of an intact core method and an acetylene inhibition technique. The intact cores were taken separately from three layers (0-10cm, 10-20cm, 20-30cm) on 8 July and 28 July, and incubated for 24h under in situ conditions. On 8 July, denitrifying enzyme activity was determined for the sieved soils collected from the three different layers. The results obtained were as follows. 1) In the laboratory experiment, denitrification rates increased with the increase in moisture content and/or bulk density of the soils. There were distinct boundary levels where denitrification rates were rapidly accelerated within the small increase of moisture content or bulk density of the soils. The levels were lowered by the addition of dried swine feces. 2) There was a negative correlation between the ratio of the gas phase and the logarithm of the denitrification rate if the soils were divided into 4 groups by the soil type (LHA or GLS) and organic materials (application or non-application). 3) The in situ denitrification rate of the soils on 8 July increased remarkably with the application of dried swine feces irrespective of soil type. The rates in the second layer (10-20cm of the soil column) were the highest of all the layers, indicating that the effect of the bulk density of soils was much more significant than that of the organic content of soils in the experiment. 4) There was a positive correlation between denitrifying enzyme activities and CO_2 emission rates from the soils. 5) The procedure to estimate the denitrification rate in upland soils where organic materials were applied was discussed. It should be emphasized that the relationship between the ratio of the gas phase and the denitrification rate obtained in this study would be a promising tool for the assessment of denitrification in soils.
