Copper phytoavailability and uptake by Elsholtzia splendens from contaminated soil as affected by soil amendments.
Pot and field experiments were conducted to evaluate bioavailability of Cu in contaminated paddy soil (PS) and phytoremediation potential by Elsholtzia splendens as affected by soil amendments. The results from pot experiment showed that organic manure (M) applied to the PS not only remarkably raised the H2O exchangeable Cu, which were mainly due to the increased exchangeable and organic fracti...
متن کاملElevated CO2 and warming effects on CH4 uptake in a semiarid grassland below optimum soil moisture
[1] Semiarid rangelands are a significant global sink for methane (CH4), but this sink strength may be altered by climate change. Methane uptake is sensitive to soil moisture showing a hump‐shaped relationship with a distinct optimum soil moisture level. Both CO2 and temperature affect soil moisture, but the direction of CH4 uptake response may depend on if the system is below or above the soil...
متن کاملSoil Moisture and Fungi Affect Seed Survival in California Grassland Annual Plants
Survival of seeds in the seed bank is important for the population dynamics of many plant species, yet the environmental factors that control seed survival at a landscape level remain poorly understood. These factors may include soil moisture, vegetation cover, soil type, and soil pathogens. Because many soil fungi respond to moisture and host species, fungi may mediate environmental drivers of...
متن کاملSeasonal Partitioning of Nitrogen by Plants and Soil Microorganisms in an Alpine Ecosystem
The seasonal dynamics of plant N assimilation and microbial N immobilization were studied in an alpine ecosystem to evaluate temporal patterns of plant and microbial N partitioning and the potential for plant vs. microbial competition for N. Plant N uptake was higher in the first half of the growing season than later in the season, as indicated by changes in biomass N and by 15N uptake. Microbi...
