“…In the plots where both organic fertilizers and synthetic fertilizers were applied, the δ 15 N values of rice might vary with the application rates of organic fertilizers and synthetic fertilizers, their δ 15 N values, and their N efficiencies for rice plants. The N efficiency of synthetic fertilizers is generally higher than those of organic fertilizers (Nishida et al, 2004;Chalk et al, 2013). Consequently, the influence of the synthetic fertilizer N with a low δ 15 N value was likely to be more apparent than those of organic fertilizers.…”

“…In an experiment conducted in a larger-scale field at the same location and using the same rice variety, the application of cattle manure compost did not significantly increase the dry matter weight of and N uptake by rice at the time of the first application (Nishida 2004; data of N uptake not shown). However, it was observed that the rice yield increased after more than 3 years of successive applications (Ohyama et al 1998;Uenosono and Nagatomo 1998).…”

“…The "Nlabeled organic materials consisted of swine manure compost (SMC) and rice bran (RB). The preparation of the I5N-labeled organic materials followed almost the same procedure as that described in a previous report (Nishida et al 2004). As a reference, a plot with inorganic N application (AS) was also prepared using (15NH4)2S0,.…”

The N recovery from 15N‐labeled swine manure compost and rice bran with or without simultaneous application of unlabeled cattle manure compost was examined in a paddy field with direct‐seeded rice during a 1‐year period (1 crop season). In all the 15N‐labeled materials including (15NH4)2SO4, the processes of N recovery from the 15N materials by rice plants were different between the plots with and without application of cattle manure compost. At the tillering stage, the N recovery rates from the 15N materials in the plots with application of cattle manure compost were significantly lower than those in the plots without application of cattle manure compost. These recovery rates, however, became close and no significant differences were observed at the maturity stage. Thus, simultaneous application of cattle manure compost could impede the N recovery from swine manure compost, rice bran as well as (NH4)2SO4.

In this study, 15 N-labeled organic materials were used to evaluate the nitrogen (N) dynamics associated with the application of organic materials to paddy fields. The decomposition of three types of organic materials, namely wheat straw, rice straw, and cattle manure compost, was evaluated by using the glass fiber-filter paper bag method. The N retention rates obtained by evaluation of N content were different from those obtained by evaluation of 15 N abundance. The fates of N in seven types of 15 Nlabeled organic materials, namely cattle manure compost, poultry manure compost, swine feces, rice straw compost, rice bran, rice straw, and wheat straw, were studied during a crop season in a warm region in Japan. The nitrogen use efficiency for swine feces, poultry manure compost, and rice bran relative to that for chemical fertilizers was as high as approximately 70%, whereas the nitrogen use efficiency for cattle manure compost relative to that for chemical fertilizers was as low as 16-19%. The N uptake from 15 N-labeled swine manure compost or rice bran simultaneously applied with cattle manure compost was slower than those from swine manure compost or rice bran alone. Furthermore, I investigated the fate of N derived from 15 N-labeled cattle manure compost over a period of three years in a region with a cool climate. Well-composted cattle manure compost was found to be a stable N source for rice plants for at least three years after application. A large amount of N derived from the cattle manure compost remained in the soil even three years after application.
