Professor Takashi Kunito of the Department of Environmental Science, Faculty of Science's paper, "pH is the cominant factor controlling the levels of phytate-like and DNA-like phosphorus in 0.5M NaHCO3-extracts of soils: evaluation with phosphatase-addition approach" was recently accepted in the journal Geoderma.
To find what factors control the concentrations of readily available organic phosphorus (Po) in soils, the research group assessed the phosphatase-hydrolyzable Po pools in arable and forest soils and evaluated their association with several soil types collected in Japan. Both phytate-like P and DNA-like P in 0.5 M NaHCO3-extracts significantly increased with decreasing soil pH, suggesting that soil pH would play a crucial role in determining the availability of Po in soils.
This research will help develop a method to increase the availability of essential nutrition in soil for plants.
This study was supported by JSPS KAKENHI Grant Number JP24510012.
