    Chemical fertilizers could be completely replaced by manure to maintain high maize yield and soil organic carbon (SOC) when SOC reaches a threshold in the Northeast China Plain by Hui LI, Wen-ting FENG, Xin-hua HE, Ping ZHU, Hong-jun GAO, Nan SUN, Ming-gang XU

    Published 2017-04-01

    The combined use of chemical and organic fertilizers is considered a good method to sustain high crop yield and enhance soil organic carbon (SOC), but it is still unclear when and to what extent chemical fertilizers could be replaced by organic fertilizers. We selected a long-term soil fertility exp...

    Basic Soil Productivity of Spring Maize in Black Soil Under Long-Term Fertilization Based on DSSAT Model by Yan ZHA, Xue-ping WU, Xin-hua HE, Hui-min ZHANG, Fu-fei GONG, Dian-xiong CAI, Ping ZHU, Hong-jun GAO

    Published 2014-03-01

    Increasing basic farmland soil productivity has significance in reducing fertilizer application and maintaining high yield of crops. In this study, we defined that the basic soil productivity (BSP) is the production capacity of a farmland soil with its own physical and chemical properties for a spec...

    Soil Organic Carbon Accumulation Increases Percentage of Soil Olsen-P to Total P at Two 15-Year Mono-Cropping Systems in Northern China by Pu SHEN, Xin-hua HE, Ming-gang XU, Hui-min ZHANG, Chang PENG, Hong-jun GAO, Hua LIU, Yong-mei XU, Song QIN, Hou-jun XIAO

    Published 2014-03-01

    Soil organic carbon (SOC) and soil Olsen-P are key soil fertility indexes but information on their relationships is limited particularly under long-term fertilization. We investigated the relationships between SOC and the percentage of soil Olsen-P to total P (PSOPTP) under six different 15-yr (1990...

    Soil productivity (SP) without external fertilization influence is an important indicator for the capacity of a soil to support crop yield. However, there have been difficulties in estimating values of SPs for soils after various long-term field treatments because the treatment without external fert...
