    Research reveals that plant-soil turnover regulates the availability of nitrogen and phosphorus




    Research reveals the availability of plant-soil turnover to regulate nitrogen and phosphorus.
    Research reveals plant-soil turnover to regulate the availability of nitrogen and phosphorus

     

    Under the guidance of researcher Liu Juxiu, Liu Xujun from the Ecological and Environmental Sciences Research Center of South China Botanical Garden, Chinese Academy of Sciences revealed that forest plant diversity and species turnover jointly regulate the availability of soil nitrogen and phosphorus

    Plant-soil interaction is an important driving force for ecosystem evolution
    .
    Based on the long-term observation data (2004~2015) of three forests (masson pine forest, coniferous and broad-leaved mixed forest, and monsoon evergreen broad-leaved forest) at different forest succession stages in Dinghu Mountain, the researchers studied the effects of plant diversity and species turnover.
    The effect of soil nitrogen and phosphorus availability

    .

    The results of the study showed that plant diversity and species turnover rate increased with forest succession, and both changed the availability of soil nitrogen and phosphorus
    .
    High plant diversity has a positive impact on the availability of soil nitrogen and phosphorus by increasing community productivity, changing litter quality, and affecting soil physical and chemical properties

    .

    However, soil nitrogen and phosphorus react differently to species turnover
    .
    Soil total nitrogen (TN) and available nitrogen (AN) are positively correlated with species turnover, while soil total phosphorus (TP) is negatively correlated with species turnover, indicating that species turnover during forest succession may lead to an imbalance in the supply of soil nitrogen and phosphorus

    .

    This study provides a possible explanation for the non-single linear relationship between soil nitrogen and phosphorus availability and plant diversity, that is, soil nitrogen and phosphorus availability is jointly regulated by species diversity and species turnover
