Over the past six decades, coastal wetlands in China have experienced rapid and extensive agricultural reclamation. In the context of saline conditions, long-term effect of cultivation after reclamation on soil chemical properties has not been well understood. We studied this issue using a case of approximately 60-years cultivation of a coastal saline marsh in Bohai Rim, northern China. The res...

Management of crop residues and soil organic matter is of primary importance in maintaining soil fertility and productivity and in minimizing agricultural impact on the environment. Our objective was to determine the effects of traf®c and tillage on short-term carbon dioxide (CO2) and water (H2O) ̄uxes from a representative soil in the southeastern Coastal Plain (USA). The study was conducted o...

Accurate simulation of agricultural management effects on N loss in tile drainage is vitally important for understanding hypoxia in the Gulf of Mexico. An experimental study was initiated in 1978 at Nashua, Iowa of the USA to study long-term effects of tillage, crop rotation, and N management practices on subsurface drainage flow and associated N losses. The Root Zone Water Quality Model (RZWQM...

Extreme meteorological phenomena resulting from climate change caused by anthropogenic emissions of greenhouse gases (GHG) require the implementation CO2 mitigation practices various industries, including agriculture. Owing to varying soil, climatic, and agrotechnical characteristics, they may have different efficiencies in mitigating soil emissions. The aim this study was evaluate impact three...

in order to assess the adaptation of elaeagnus angustifolia l. and fraxinus rotundifolia mill afforestation around tabriz international airport, the qualitative and quantitative characteristics of trees were measured in 96 experimental circular plots with a size of 300 m2. to study the edaphic effects of these species, nine samples were randomly collected from 0-10 cm and 10-20 cm depth of soil...
