| 内容記述 | In view of demonstrating the systematic technologies for environmentally conscious production, an attempt was made to reduce the dose of dried hog feces applied for the cropping system of lettuce-carrot at the farmer's field with the conventional application rate of 68kgN/10a, based on the nitrogen balance under solarization before sowing carrot. The soi1 fertility status of the farmer's field, i,e., available contents of nitrogen, phosphorus and potassium were higher than those of Yawara Upland Field of NARC, probably due to the long-term application of dried hog feces at the farmer's field. The nitrogen balance for the cropping of lettuce-carrot was gradually improved with the 30% reduction in 1999 and the 70% reduction in 2000, compared with the conventional rate of nitrogen application. However, in case of the 90% reduction in 2001, the nitrogen amount recovered by lettuce and carrot exceeded the nitrogen amount applied, leading to the negative value of nitrogen balance. However, the target yields of lettuce and carrot were obtained even in 2001. The amount of inorganic nitrogen released from the dried hog feces exceeded the amount of nitrogen recovered by lettuce and carrot only in 1999, while sum of inorganic nitrogen released from the dried hog feces and the soil (0-15cm) was higher than the amount of nitrogen recovered by lettuce and carrot in 2000 and 2001. The amount of inorganic nitrogen released from the soil (0-60cm) was estimated to be 35kg/10a and the sum of inorganic nitrogen supplied was evaluated to be 40kg/10a in 2001. The inorganic nitrogen balance for the cropping of lettuce and carrot was improved by 24kg/10a with the 90% reduction in 2001, compared with the conventional rate. Thus, the amount of nitrogen leaching was estimated to be reduced by 45% in 2001. At the vegetable fields with relatively high soil nitrogen fertility status such as the farmer's field examined, the amount of inorganic nitrogen released from the soil during the cropping period should be considered for the reasonable nitrogen application. At the same time, Nematode antagonistic plants should be introduced to recover excess nutrients from the soil after vegetable cropping. | |||||||||||||||||||||||
