Sources of nitrous oxide emitted from European forest soils
Forest ecosystems may provide strong sources of nitrous oxide (N2O), which is important for atmospheric chemical and radiative properties. Nonetheless, our understanding of controls on forest N2O emissions is insufficient to narrow current flux estimates, which still are associated with great uncertainties. In this study, we have investigated the quantitative and qualitative relationships betwe...
متن کاملHerbicidal Activity and Residual States of Metolachlor in Upland Soils
The residues of metolachlor [2chloro-2'-ethyl-N-(2-methoxy-l-methylethyl)6'-methylacetanilide] applied to a soybean field were determined separately as to water-soluble and water-insoluble ingredients and were found to fluctuate with precipitation. The half life of all metolachlor was calculated as 40 to 60 days in 1990 and 4 to 5 days in 1991. The half life of the water-soluble ingredients, ho...
متن کاملMoisture Quotients for Ammonia Volatilization from Four Soils in Potato Production Regions
Ammonia (NH3) emission from nitrogen (N) fertilizers used in agriculture decreases N uptake by the crop and negatively impacts air quality. In order to better understand the factors influencing NH3 emission from agriculture, this research was conducted with four major soils used for potato production: Biscayne Marl Soil (BMS, pH 7.27), and Krome Gravelly Loam (KGL, pH 7.69) from Florida; and Qu...
متن کاملHigh Water Regime Can Reduce Ammonia Volatilization from Soils under Potato Production
This research was conducted with Biscayne marl soil and Krome gravelly loam from Florida and Quincy fine sand and Warden silt loam from Washington to determine ammonia (NH3) volatilization at various temperature and soil water regimes. Potassium nitrate (KNO3), ammonium nitrate (NH4NO3), ammonium sulfate [(NH4)2SO4], or urea were applied to the soil at a rate of 75 kg N ha . Soil water regime w...
متن کاملMethane emissions from the trunks of living trees on upland soils.
Upland forests are traditionally thought to be net sinks for atmospheric methane (CH4 ). In such forests, in situ CH4 fluxes on tree trunks have been neglected relative to soil and canopy fluxes. We measured in situ CH4 fluxes from the trunks of living trees and other surfaces, such as twigs and soils, using a static closed-chamber method, and estimated the CH4 budget in a temperate upland fore...
