pH is the dominant factor in controlling levels of Po in soils
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.
