“…The impairment effect of ammonium sulfate on seedling establishment was stronger than that of potassium sulfate (Fig. 2) probably because ammonium ions also impaired seedling establishment under submerged soil (Hara and Toriyama, 1998;Kanno et al, 1999;Yamamoto et al, 2004). The failure of ammonium chloride to impair seedling establishment in Exp.…”

“…Ammonium salts, which are used as nitrogen fertilizers in paddy fields, also impair the establishment of seedlings in submerged soil (Hara and Toriyama, 1998;Kanno et al, 1999). Yamamoto et al (2004) reported that ammonium sulfate was the most detrimental among the major ammonium fertilizers for non-coated seeds in cold regions, although they did not discuss the possibility of sulfide ion generation as a cause of the impaired establishment associated with ammonium sulfate treatment.…”

Direct seeding is a labor-saving rice cultivation method, but poor establishment is a major obstacle to the widespread use of this practice. This study examined the suppressive effect of ammonium sulfate, a nitrogen fertilizer, on seedling establishment in submerged soil. Establishment was impaired even at 20ºC by the application of sulfate salts, including ammonium sulfate and potassium sulfate, but not by ammonium chloride. Impairment by ammonium sulfate did not occur in autoclaved soil. In addition, the redox potential in the soil near the seeds decreased rapidly to levels that allowed sulfide ion generation, even at 20ºC. The sulfur concentration in the soil near the seeds decreased with the decline in redox potential, suggesting that sulfide ions were transformed from soluble sulfate ions into insoluble iron sulfide through binding with ferrous ions near the seeds. These results imply that sulfate ions may be transformed into sulfide ions by bacteria only around the seeds if sufficient sulfate ions are present in the soil, thereby impairing the establishment of seeds sown directly in submerged soil, even under cool springtime conditions and in paddy fields that do not dry out prior to submergence.

“…In some reports, relationships between seedling establishment and soil conditions were suggested. Hara and Toriyama (1998) reported that a high ammonium nitrogen concentration in the soil solution inhibited seedling establishment. Kanno et al (1999) also indicated that rice establishment was inhibited by ammonium nitrogen when the concentration in the soil solution exceeded 2 mg kg-I.…”

The effects of the nitrogen application rate and type of nitrogen fertilizer on rice seedling establishment for seeds without or with calcium peroxide coating under drained paddy field conditions were investigated. The seedling establishment rate for the seeds without coating decreased with the application of ammonium sulfate CAS) at the rates of 4 and 8 g m-2 • The pH in the soil solution was in the appropriate range for rice growth, and the ferrous ion concentration and EC in the soil solution were lower than the threshold for rice growth in all the plots. The ammonium nitrogen concentrations in the soil solution in the AS application plots were exceeded 2 mg kg-I, which is the threshold for seed emergence. Seedling establishment for the seeds with calcium peroxide coating was not inhibited by the AS application even at the rate of 8 g m-2 • The application of ammonium phosphate CAP), urea CU), and polyolefin-coated urea CPCU) at the rate of 4 g m-2 did not inhibit the seedling establishment in the case of both calcium peroxide-coated seeds and non-coated seeds. The ammonium nitrogen concentration in the soil solution at the time of sowing was less than 2 mg kg-1 in all the treatments except for the AS treatment. These results showed that nitrogen application, which increases the ammonium nitrogen concentration in the soil solution at sowing, inhibits seedling establishment for non-coated seeds and does not inhibit seedling establishment for coated seeds.
