Groundwater quality is defined by various water quality parameters. The aims of the
research are to understand the relationships among different groundwater quality …

Excessive levels of Fe, Mn and As are the main factors affecting groundwater quality in
Songliao plain, northeast China. However, there are few studies on the source and …

In order to employ appropriate management measures for rice-crayfish farming systems in
the Jianghan Plain, it is critical to evaluate how this process affects the soil quality. By taking …

Alternate wetting and drying irrigation (AWD) is promulgated as a practice for reducing
irrigation water usage in rice production; however, the implications of AWD on soil properties …

Nitrification and denitrification processes are major pathways for nitrogen (N) losses in
agricultural soils, and highly depend on soil properties. Improved understanding of soil …

Paddy soils experience long-term redox alternations affecting the interactions between the
biogeochemical cycling of iron (Fe) and carbon (C). Differences in particle aggregation and …

Soil microorganisms play important roles in nitrogen transformation. The aim of this study
was to characterize changes in the activity of nitrogen transformation enzymes and the …

Biochar can be a soil amendment that increases nutrient retention and carbon (C)
sequestration in rice paddy systems. However, biochar can lose nutrient during its …

Soil physiochemical and biological properties have been demonstrated as key controllers of
nitrogen (N) transformation in soil; however, the roles of different soil properties in regulating …

In rice production, water-saving irrigation management is expanding and likely alters depth
profiles of soil moisture, redox potential (Eh) and microbial activity. It is, however, unclear …
