Moisture effect on carbon and nitrogen mineralization in topsoil of Changbai Mountain, Northeast China
soil moisture soil C and N mineralization incubation experiment Changbai Mountain Northeast China
2015/3/27
Changbai Mountain Natural Reserve (1,985 km2 and 2,734 m a.s.l.) of Northeast China is a typical ecosystem representing the temperate biosphere. The vegetation is vertically divided into 4 dominant zo...
Seasonally dependent impacts of grazing on soil nitrogen mineralization and linkages to ecosystem functioning in Inner Mongolia grassland
Typical steppe Grazing intensity Season Soil inorganic N pools Net N mineralization Soil temperature and moisture BiomassN content Nitrogen use efficiency
2015/2/4
Previous studies have suggested grazing may alter nitrogen (N) cycling of grasslands by accelerating or decelerating soil net N mineralization. The important mechanisms controlling these fluxes remain...
Carbon and nitrogen mineralization from selected organic resources available to smallholder farmers for soil fertility improvement in Zimbabwe
Cattle manure Mangifera indica miombo litter N mineralization and immobilization
2010/9/10
A study was conducted to assess the N release dynamics of three organic resources widely used by smallholder farmers in sub-Saharan Africa to improve soil fertility. Addition of cattle manure, miombo ...
Characteristics of Nitrogen Mineralization in the Soil of Japanese Cedar (Cryptomeria japonica) and their Responses to Environmental Changes and Forest Management
forest management nitrification ratios of mineralized to total nitrogen soils of sugi stands
2009/8/28
Knowledge of nitrogen mineralization in the soils of sugi (Cryptomeria japonica) stands is important for understanding the effects of forest management and environmental changes on nutrient cycling in...
Patterns of Soil Nitrogen Release in Paddy Fields of Warm Regions in Japan and Diagnosis of Fertilizer Application : II. Characteristics of soil nitrogen mineralization and nitrogen uptake patterns of rice plants in Fukuoka Prefecture
Amount of nitrogen uptake Fertilizer nitrogen Nitrogen mineralization Paddy soils Soil nitrogen
2009/8/4
Topsoils collected from various regions in Fukuoka Prefecture were incubated and the amount of mineralized nitrogen was measured. The relationship between the mineralized nitrogen amount (N) and the ...
A Simplified Model for Estimating Nitrogen Mineralization in Paddy Soil
Drying effect Model Nitrogen mineralization Paddy soil Soil moisture before flooding Soil incubation Temperature
2009/7/30
The estimation of available nitrogen in paddy soil is important in order to evaluate rice productivity and to improve fertilizer management. In this study, a simplified model is proposed for estimatin...

Nitrogen Paddy rice Paddy-upland rotation Single crop Soil Nitrogen mineralization
2009/7/8
Soil nitrogen mineralization and nitrogen absorptions by rice in paddy-upland rotational fields (rice-wheat-soybean) were studied in the Nara basin for four years (2000-2003) in comparison with those ...
Apparent Nitrogen Mineralization Rates of Several Green Manures Incorporated in Soil and the Application Effects on Growth of Komatsuna Plants
green manure hairy vetch sunflower crotalaria
2010/12/2
Apparent nitrogen mineralization rates and the availability of released nitrogen to komatsuna plants succeeding green manures (GMs) incorporated to soil were investigated using a pot experiment to dev...
