Comparing Energy Use in Conventional and Organic Cropping Systems
Energy consumption can vary signifi cantly between conventional and organic production systems when accounting for direct energy inputs as well as indirect energy involved in manufacturing, shipping and applying pesticides and nitrogen-based fertilizers. Because organic agriculture reduces the amount of indirect energy inputs, it is often assumed that organic agriculture is less energy intensiv...

متن کاملThe role of soil organic matter in maintaining soil quality in continuous cropping systems
Maintenance and improvement of soil quality in continuous cropping systems is critical to sustaining agricultural productivity and environmental quality for future generations. This review focuses on lessons learned from long-term continuous cropping experiments. Soil organic carbon (SOC) is the most often reported attribute from long-term studies and is chosen as the most important indicator o...

متن کاملElevated atmospheric CO2 effects on biomass production and soil carbon in conventional and conservation cropping systems
Increasing atmospheric CO2 concentration has led to concerns about potential effects on production agriculture as well as agriculture’s role in sequestering C. In the fall of 1997, a study was initiated to compare the response of two crop management systems (conventional and conservation) to elevated CO2. The study used a split-plot design replicated three times with two management systems as m...
