Global concerns for the sustainability of agriculture have emphasized the need to reduce the use of mineral fertilizer. Although phosphorus (P) is accumulated in farmland soils due to the long-term application of fertilizer, most soil P is not readil

Potentially significant effects of soil fauna on plant litter decomposition are difficult to quantify by the commonly used litter bag approach due to physical constraints of meshed bag and inevitable loss of litter fragments through the mesh. We thus

Applications of iron- (Fe-) bearing materials represent an effective countermeasure for decreasing the dissolution of arsenic (As) in soil under anaerobic conditions. In this study, we investigated the effects of Fe amendments (ferrihydrite-based and

Changes in total carbon (C) concentrations in topsoil were examined in response to organic amendments (OAs) in Japanese orchards and tea gardens at the farm level using 20 years of survey data. A rolling nationwide survey was conducted four times bet

The characteristics of Japanese soil were developed by wide paddy field farming, the influence of volcanic ash on soil, and a perudic moisture regime under temperate climatic conditions. Major soil classifications in Japan have developed in line with

Elevated arsenic (As) concentrations in rice and the soil solution result from changes in soil redox conditions, influenced by the water management practices during rice cultivation. Microscale changes in redox conditions from rhizosphere to soil mat

In order to help maintain soil fertility, a national survey was conducted in Japan, beginning in 1979. Both soil samples and questionnaires given to farmers on agricultural management were collected. By using the dataset, we described the long-term a
