“…Decomposition of organic matter in anaerobic soil is known to release a large amount of organic acids, including aliphatic acids (Johnson et al. 2006) and aromatic acids (Tanaka 1990; Tanaka et al. 1990), which inhibit rice seedling growth (Chandrasekaran and Yoshida 1973; Rao and Mikkelsen 1977; Tanaka and Nishida 1998; Tanaka et al.…”

Aerobic rice is a water-saving technology in which rice grows in non-puddled and non-saturated (aerobic) soil without ponded water. A gradual decline in rice yield was found in field plots at the farm of the International Rice Research Institute, Los Bañ os, Philippines, where rice has been cultivated continuously for 10 cropping seasons under aerobic rice conditions. We investigated whether abiotic soil factors lead to the observed yield decline. An aerobic rice pot experiment was conducted using field soils from flooded rice plots and from the 10-season-long aerobic rice cultivated plots (referred to as 1st-season and 11th-season aerobic rice, respectively). Subtreatments consisted of soil sterilization by oven heating (at 95°C or higher for 24 h) and a control treatment. The above-ground biomass of 1st-season aerobic rice was significantly greater than that of 11th-season aerobic rice in both the oven-heating and control treatments. Oven heating increased soil N availability and above-ground biomass accumulation over the control in both 1st-season and 11th-season aerobic rice, but the above-ground biomass in the oven-heated 11th-season aerobic rice was still significantly lower than that of the oven-heated and even the untreated (control) 1st-season aerobic rice. These results suggest that abiotic factors contribute to the gradual yield decline observed in the field plots.

“…2P, 3P, and BA inhibited N uptake of rice plants at concentrations of 1,100, and 100 J1.M, respectively. The highest concentrations of2P, 3P, and BA in the soil solutions collected from paddy rice fields were 4.1, 2.8, and 22.3 J1.M, respectively (Tanaka 1990). The concentration of 2P exceeded the inhibitory concentration for N uptake.…”

“…In a previous report (Tanaka and Nishida 1996), we showed that the activity of 15N uptake from 15NH 4 + introduced into the soil decreased by straw application. We found the accumulation of some aromatic acids in soils to levels inhibitory to root elongation when fresh wheat straw was applied (Tanaka 1990;Tanaka et al 1990). No attempt were made to investigate the effects of aromatic acids on N uptake by rice seedlings.…”
