SYNTHESIS AND EMERGING IDEAS Mycorrhizal associations of dominant trees influence nitrate leaching responses to N deposition
Temperate forests receive some of the highest rates of nitrogen (N) deposition in the world. While numerous studies have investigated the effects of N enrichment on forests, there is little consensus on why some forests become N saturated while others do not. To investigate this, we used a multi-factor metaanalysis to simultaneously estimate the relative importance of several environmental, exp...
متن کاملAssessing the risk of N leaching from forest soils across a steep N deposition gradient in Sweden.
Nitrogen leaching from boreal and temporal forests, where normally most of the nitrogen is retained, has the potential to increase acidification of soil and water and eutrophication of the Baltic Sea. In parts of Sweden, where the nitrogen deposition has been intermediate to high during recent decades, there are indications that the soils are close to nitrogen saturation. In this study, four di...
متن کاملApplication of SWAT Model to Simulate Nitrate and Phosphate Leaching from Agricultural Lands to Rivers
In the present study, the amount of nitrate and phosphate leaching from agricultural lands into the Zanjanrood River in Iran was simulated using the Soil & Water Assessment Tool (SWAT) model. The measured average monthly discharges at the Sarcham station were used to calibrate and validate the SWAT model, and the SWAT Calibration and Uncertainty Program (SWAT-CUP) model was applied to perform t...
متن کاملClipping contributions to nitrate leaching from creeping bentgrass under varying irrigation and N rates
The effect of clipping management on nitrate (NO3) leaching beneath creeping bentgrass (Agrostis stolonifera L.) has received little attention. The objective of this experiment was to examine the effects of returning grass clippings to creeping bentgrass in combination with N fertilization and irrigation on NO3 leaching. A 30-week long experiment was conducted using fairway-height creeping bent...
متن کاملMicrobial Potential for Ecosystem N Loss Is Increased by Experimental N Deposition
Fossil fuel combustion and fertilizer use has increased the amount of biologically available N entering terrestrial ecosystems. Nonetheless, our understanding of how anthropogenic N may alter the physiological mechanisms by which soil microorganisms cycle N in soil is still developing. Here, we applied shotgun metagenomics to a replicated long-term field experiment to determine how two decades ...
