Carbon Sequestration Efficiency of Organic Amendments in a Long-Term Experiment on a Vertisol in Huang-Huai-Hai Plain, China
Soil organic carbon (SOC) sequestration is important for improving soil fertility of cropland and for the mitigation of greenhouse gas emissions to the atmosphere. The efficiency of SOC sequestration depends on the quantity and quality of the organic matter, soil type, and climate. Little is known about the SOC sequestration efficiency of organic amendments in Vertisols. Thus, we conducted the ...
متن کاملExploring the relationship between irrigation water requirements and potential yield in the Huang-Huai-Hai plain
By using the GIS technologies, we interpolate the site-based meteorological data into climatic surface data, which are the main input parameters for the CropWat model, used to estimate the reference evapotranspiration (ET0). And then by combining the ET0 with the information on share of cultivated land decoded from the Landsat TM/ETM digital imagines covering the entire case study area, the Hua...

By using qualitative and quantitative analysis based on the basic data collected over 300 counties in the Huang-Huai-Hai Plain, considering such indicators as the natural resources of the plains and ...
متن کاملImpacts of Climate Change on Water Requirements of Winter Wheat over 59 Years in the Huang-Huai-Hai Plain
Huang H., Han Y., Song J., Zhang Z., Xiao H. (2016): Impacts of climate change on water requirements of winter wheat over 59 years in the Huang-Huai-Hai Plain. Soil & Water Res., 11: 11–19. Daily data from 40 meteorological stations in the Huang-Huai-Hai Plain from 1955 to 2013 were analyzed using the Mann-Kendall test and partial correlation to determine the temporal trends of meteorological f...
متن کاملDry Matter Production, Photosynthesis of Flag Leaves and Water Use in Winter Wheat Are Affected by Supplemental Irrigation in the Huang-Huai-Hai Plain of China
Winter wheat is threatened by drought in the Huang-Huai-Hai Plain of China, thus, effective water-saving irrigation practices are urgently required to maintain its high winter wheat production. This study was conducted from 2012 to 2014 to determine how supplemental irrigation (SI) affected soil moisture, photosynthesis, and dry matter (DM) production of winter wheat by measuring the moisture i...
