| 内容記述 | The efficient nutrient management technology for the carrot cultivation was developed taking account of nutrient balance and nitrogen uptake pattern, in order to reduce the nitrogen leaching from the rooting zone. Available nutrient status with nitrogen, phosphorus and potassium at the experimental field was relatively low compared with volcanic ash upland soils in the Kanto region. The nitrogen and phosphorus balance became much lower in the 50% reduction than in the standard application rates of nitrogen and phosphorus for the carrot cultivation. The carrot yield was similar in the both cases. Similar results were also obtained with the use of the cattle feces compost substituted for the half out of the 50% reduction of the standard application rate of nitrogen and with the treatment of solarization at the same time. In the cropping pattern of lettuce and carrot, much amounts of non-recovered nitrogen, phosphorus and potassium were found from the nutrient balance in case of the standard application rates along with cattle feces compost for lettuce. Thus, the application rates of the three elements for the lettuce should be reduced to improve the nutrient balance. In the early growth stage of carrot, the amount of nitrogen taken up by carrot was relatively low. Thus, coated fertilizer suitable for the pattern of nitrogen uptake, i.e., LPS100 was considered to be appropriate. On the other hand, in the case of the use of solarization, LPS120 might be useful because of repression of nitrogen release during the period from solarization to the early growth stage of carrot. The close relationship was found between the inorganic nitrogen balance in consideration of the amount of inorganic nitrogen released from the soil (0-60cm) and cattle feces compost, and the mean annual nitrate nitrogen concentration in the soil solution at the depth of 60cm. Based on the relationship, the method to estimate nitrate nitrogen concentration in the soil solution was proposed. Using this method, the amount of nitrogen leaching was evaluated to be reduced by 35% through the reduction of 50% of the standard application rate of nitrogen. | |||||||||||||||||||||||
