Effects of field experimental warming on wheat root distribution under conventional tillage and no‐tillage systems
Despite the obvious importance of roots to agro-ecosystem functioning, few studies have attempted to examine the effects of warming on root biomass and distribution, especially under different tillage systems. In this study, we performed a field warming experiment using infrared heaters on winter wheat, in long-term conventional tillage and no-tillage plots, to determine the responses of root b...
متن کاملEffects of fertilizer placement on solute leaching under ridge tillage and no tillage
Elevated nitrate concentrations in ground water can be a problem in agricultural areas, especially where soils are sandy. Tillage operations, such as ridge tillage (RT) and no tillage (NT) can reduce runoff and erosion but leaching of soluble nutrients could adversely impact groundwater. In a 2-year study, Br was used to trace the effects of fertilizer placement on solute movement under corn (Z...
متن کاملWeed Control Using Conventional Tillage, Reduced Tillage, No-Tillage, and Cover Crops in Organic Soybean
Soybean field experiments were performed to investigate the weed-suppressing effects of different tillage systems and cover crop mulches at two locations in southwest Germany during 2014 and 2015. The influence of three different tillage systems on weed control efficacy, soybean plant density, and crop yield was determined. In the no-till system (NT), two different cover crops, (rye and barley)...
متن کاملSoil Aggregates and Associated Organic Matter under Conventional Tillage, No-Tillage, and Forest Succession after Three Decades
Impacts of land use on soil organic C (SOC) are of interest relative to SOC sequestration and soil sustainability. The role of aggregate stability in SOC storage under contrasting land uses has been of particular interest relative to conventional tillage (CT) and no-till (NT) agriculture. This study compares soil structure and SOC fractions at the 30-yr-old Horseshoe Bend Agroecosystem Experime...
متن کاملTillage and soil quality Tillage practices for sustainable agriculture and environmental quality in different agroecosystems
For centuries tillage has been used to prepare suitable seedbed to grow crops, and to control weeds and incorporate fertilizers, pesticides, manures and other amendments. In early years conversion of native ecosystems by tillage helped to unlock nutrients stored in soil organic matter, and thus `mine' naturally fertile soils to grow crops with minimum inputs for the growing population. However,...
