    The development of a coupled model (PCPF-SWMS) to simulate water flow and pollutant transport in Japanese paddy fields

    A new coupled model (PCPF–SWMS) was developed for simulating fate and behavior of pollutant in paddy water and paddy soil. The model coupled the PCPF-1, a lumped model simulating pesticide concentrations in pa...

    Micro paddy lysimeter for monitoring solute transport in paddy environment

    The micro paddy lysimeter (MPL) was developed and evaluated for its performance to simulate solute transport in paddy environment under laboratory conditions. MPLs were constructed using soil collected from Fi...

    Phyto-purification of livestock-derived organic waste by forage rice under subtropical climate

    Soil and water pollution caused by organic waste is a concern for livestock-breeding areas. Nitrogen balance in a paddy-field water-purifying system in which cattle feces were applied was studied for 4 years t...

    Behavior of carbon dioxide in soils affected by tillage systems

    Agricultural management plays an important role in the storage of carbon in soils. The behavior of soil CO2 in an Andisol in two different tillage systems (no tillage and tillage) was studied. Soil-column incubat...

    Predicting soil moisture condition in arbitrary agricultural lands using the digital soil map and soil physical properties database

    To predict soil moisture condition in arbitral agricultural lands by taking spatial distribution of soil type in a watershed into account, we investigated the possible proper methods of determining the soil hy...

    Macropores regulate CO2 behavior in an andisol soil

    Macropores resulting from soil pedogenesis, biological activity, and agricultural practices play important roles in soil water, chemical and gas transport; however, seldom studies focus on the effect of soil m...

    Predicting soil water movement in converted soybean fields under high moisture condition

    Crops adapt to variable soil moisture by varying the distribution of their roots and patterns of water absorption. Meanwhile, proper numerical model for predicting soil moisture in croplands especially under h...
