No-till improves near-surface soil properties
Near-surface soil aggregate structural properties such as aggregate size distribution, stability, strength, and wettability determine the extent to which a soil will erode under water or wind erosive forces. Knowledge of aggregate structural properties is especially important in semiarid regions, such as the Great Plains, where low precipitation, high evaporation, and variable biomass production ...

Soil carbon storage is not always influenced by tillage practices
The practice of no-till has increased considerably during the past 20 yr. Soils under no-till usually host a more abundant and diverse biota and are less prone to erosion, water loss, and structural breakdown than tilled soils. Their organic matter content is also often increased and consequently, no-till is proposed as a measure to mitigate the increase in atmospheric carbon dioxide ...

Will large amounts of soil carbon be released to the atmosphere if grasslands are converted to energy crops?
Grasslands in the Conservation Reserve Program (CRP) in the United States may be increasingly converted to growing bioenergy grain crops. Questions abound regarding the fate of carbon sequestered in the soil during the CRP program by perennial grasses if the land is converted to grain crop production and the potential effectiveness of no-till production systems to conserve the sequestered soil ...

Can one-time tillage improve no-till?
A one-time tillage has no adverse effects on yield or soil properties on no-till land, according to field research conducted at the University of Nebraska-Lincoln. Although tillage is another expense for farmers and generally increases the risk of soil erosion, a one-time tillage may be performed to correct some problem, such as a perennial weed problem. The feasibility study was conducted for ...

Experiment demonstrates 110 years of sustainable agriculture
A plot of land on the campus of Auburn University shows that 110 years of sustainable farming practices can produce similar cotton crops to those using other methods. In 1896, Professor J.F. Duggar at the Agricultural and Mechanical College of Alabama (now Auburn University) started an experiment to test his theories that sustainable cotton production was possible on Alabama soils if growers ...

Respect the Rotation: Glyphosate-Resistant Weeds One Year Later
Growers, consultants, weed scientists, researchers and government agency officials who participated in the July 2010 launch of the Respect the Rotation™ initiative have taken measureable steps toward progress in the fight against the proliferation of glyphosate-resistant weeds. But university experts still believe the system will fail if current practices continue. There is enough of an ...

Record-breaking $17.3 billion in crop losses last year; significant portion potentially avoidable
Report shows county-by-county analysis of impacts in the ten states with highest crop insurance losses due to extreme weather: Extreme weather forced the Federal Crop Insurance Program (FCIP) to pay out a record-breaking $17.3 billion in crop losses last year, much of which could have been prevented using water-smart strategies, according to the Natural Resources Defense Council. Payments made ...
