摘要:Abstract(#br)Increase in farm size (IFS) can reduce fertilizer use but it may accelerate soil erosion, particularly stream channel (SC) erosion and associated nutrient losses, due to reduced farmland heterogeneity. But these positive and negative environmental impacts of IFS...

摘要:Abstract(#br)Worldwide, karst terrain is highly sensitive to human activity due to extensive areas of thin soil and rapid water flow to groundwater. In the southwest China karst region, poor farming decisions can promote land degradation and reduce water quality with negative con...

摘要:Abstract(#br)Coffee is a key export commodity of East Africa, but average smallholders’ yields are low. To guide sustainable yield improvements of smallholders’ coffee systems, we investigated coffee yield components in three different types of coffee cropping systems along ...

摘要:Abstract(#br)As global surface temperatures rise, the percentage of total precipitation that falls in extreme events is increasing in many areas (“rainfall intensification”), including the U.S. Midwest, a major agricultural region. While it is well known that losses of nitro...

摘要:Abstract(#br)The widespread use of neonicotinoids has increased the risk of non-point source pollution. Previous studies mainly focused on neonicotinoid transport by runoff on gentle slopes and ignored the role of sediment. Neonicotinoid migration due to erosion could be underest...

摘要:Abstract(#br)To better understand the effects of fertilizer on soil methane (CH 4 ) diffusion and consumption in semi- arid region, we investigated the subsurface CH 4 concentrations at seven depths in the mineral soil and analysed the CH 4 fluxes between soil horizons at th...

摘要:Abstract(#br)It is well recognized that soil tillage practice and straw returning treatment redistribute carbon (C) in soil and promote the bacterial biomass and diversity. Yet, to date the relative impact of soil tillage practice and straw returning on C in soil different f...

摘要:Abstract(#br)Soil compaction from livestock treading during winter grazing of forage crops on cultivated soils may be harmful to subsequent crop production and nitrogen (N) loss. This study focussed on determining: (1) how compaction and high inputs of N from livestock urine...

摘要:Abstract(#br)Large reservoirs of organic carbon (OC) store in deep soils (>1 m below land surface) are not usually included in regional and global terrestrial C inventories. Chinaös Loess Plateau (CLP), which has the worldös deepest loess deposit and has experienced long-ter...

摘要:Abstract(#br)In the United States, current crop production often favors simplified rotations of maize and soybeans in conjunction with a heavy reliance on synthetic inputs that consequently degrade environmental health and increase production costs, without necessarily impro...
