Research

With an aim to mitigate eutrophication, this study has focused on the nutrient influx from non-point sources. The following two research subjects are conducting.

Theme1：Development of a quick method to analyze bioavailable phosphorus in soil and suspended sediment

Overview

Controlling eutrophication is suggested in reference to a fraction of bioavailable phosphorus (BAP) in suspended sediments influx from catchment basins rather than the total amount of phosphorus, particularly during precipitation. However, the current methods of quantifying particulate BAP are time-consuming and tedious. Here, we are researching the use of ultrasonication to quantify particulate BAP in soil and suspended sediment from catchment basins. The new less time-consuming quantification process using ultrasonic extraction will allow automatic analysis of more samples as well as help to redefine the environmental standards.

Theme2：Direction to reduce the environmental load of nutrient pollutants from agriculture

Overview

Nutrient loadings from fertilized agriculture are considered to be a major cause of eutrophication. Many attempts have been made at enhancing the input effectiveness of fertilizers, water and heat energy, thus making it more environmentally friendly and driving better cost performance. With a view to sustainable development goals, this study has designed a low-emission greenhouse horticulture, where the effects of reducing fertilizers on plant growth state are carefully monitored by a precisely biological information system.
