New roller crimper concepts for mechanical termination of cover crops in conservation agriculture
Rollers crimpers have been used in conservation agriculture to terminate cover crops; however, excessive vibration generated by the original straight-bar roller design has delayed adoption of this technology in the United States. To avoid excessive vibration, producers generally reduce operating speeds that increase the time needed to perform the field operation. The objectives of this research...
متن کاملCover Crops and Fertilization Alter Nitrogen Loss in Organic and Conventional Conservation Agriculture Systems
Agroecosystem nitrogen (N) loss produces greenhouse gases, induces eutrophication, and is costly for farmers; therefore, conservation agricultural management practices aimed at reducing N loss are increasingly adopted. However, the ecosystem consequences of these practices have not been well-studied. We quantified N loss via leaching, NH3 volatilization, N2O emissions, and N retention in plant ...
متن کاملCover crops and control of arthropod pests of agriculture
Cover crops can harbor both harmful and beneficial arthropods (1, 3). Damage to cover crops themselves is rarely of concern; more important is the possibility that pests harbored amid cover crops may disperse to adjoining cash crops [see Kennedy and Margolies (31) for a discussion of the dynamics of such mobile pests]. Here, I explore the roles that cover crops play in the life cycles and popul...

متن کاملبررسی رابطه میان تراکم پوشش‌گیاهی و جانوران خاکزی در جنگل های حاشیه رودخانه کرخه به‌منظور تعیین حاشیه امن یا ضربه گیر رودخانه
The spatial distribution of soil organisms is influenced by the plant cover, thus resulting in a horizontal mosaic of areas subjected to gradients of nutrient availability and microclimatic conditions.This study was conducted to investigate the spatial variability of soil macrofauna in relation to vegetation density in the riparian forest landscape of Karkhe. The vegetation density was determin...
