Based on the results, we used the sigmoidal types of coated urea slow release N fertilizer in which nitrogen release starts at a one- or two-month period after application, in upland field converted from paddy field in 2001. Basal or top dressing of selected coated urea fertilizers of two types were effective in increasing soybean yields. Two kinds of the coated urea started to release N after the R3 stage, and they did not inhibit nitrogen fixation by the root nodules. 1) It was confirmed that the relative dependence on nitrogen fixation by soybean root nodules follows a hyperbolic curve with the maximum at the R3 stage. The sensitivity of the root nodules to the NO_3^- seemed to be obvious until the R3 stage, but after the R3 stage, nitrate absorption appeared to be beneficial to maintain nitrogen fixation activity through promoting photosynthetic activity. Therefore, the fertilizer nitrogen supply after the R3 stage harmonizes with the nitrogen fixation of root nodules. 2) Sigmoidal releasing-type coated urea (CUS), which starts to release fertilizer nitrogen after R3 stage, was adopted. CUS120 was suitable for basal application and CUS60 for top-dressing. To select a type, we simulated the soil temperature at fertilization depth. 3) Neither the CUS120 basal application nor the CUS60 top-dressing depressed the nitrogen fixation. In both CUS treatments, degradation of the leaf chlorophyll was restrained in the maturing stage. The seed yield in the CUS120 treatment increased by more than 10% above the control, and in the CUS60 treatment, indreased by 19% mofe than the control (439 g m^\u003c-2\u003e). Moreover, no decline in the seed quality was observed in either CUS treatment. 4) The top dressing of CUS60 fertilizer was applied in a farmer\u0027s field. The seed yield of CUS60 top-dressing achieved 449 g m^\u003c-2\u003e, or 21% over the conventional field (370 g m^\u003c-2\u003e). Still more promisingly, crude protein of seeds in the CUS60 treatment increased, compared with that for the conventional field.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3":
