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...

Comparisons of organic and conventional maize and tomato cropping systems from a long-term experiment in California

Yield differences and trends, organic matter accumulation, and the loss of nutrients to deeper soil horizons are discussed using data from organic and conventional maize/tomato cropping systems from the Long Term Research on Agricultural Systems Project (LTRAS) at the University of California, Davis. Compared to the conventional system, higher and increasing yields of tomatoes were observed in ...

Earthworm populations in relation to soil organic matter dynamics and management in California tomato cropping systems

Earthworms are key regulators of soil structure and soil organic matter (SOM) dynamics in many agroecosystems. They are greatly impacted by agricultural management, yet little is known about how these factors interact to control SOM dynamics. This study sought to explore linkages between agricultural management, earthworms and aggregate associated SOM dynamics through a survey of tomato (Solanu...
