Vineyard Weed Seedbank Composition Responds to Glyphosate and Cultivation after Three Years
This research compared effects of the weed control practice, soil cultivation, and the conventional practice, glyphosate application on weed seedbank, in a vineyard system. The experiment was conducted in a commercial wine-grape vineyard in the Napa Valley of northern California from 2003 to 2005. The annual treatments were ‘‘winter–spring glyphosate,’’ ‘‘spring cultivation,’’ ‘‘fall–spring cul...
متن کاملcombining topographic and soil attributes for spatial prediction of model parameters of soil shrinkage curve
this study was conducted to investigate the spatial variability of model parameters of soil shrinkage curve in cherlgerd district, chaharmahal-va-bakhtiari province. ninety nine locations were selected and soil clods were collected from the 0-10 cm layer and brought to the laboratory. soil shrinkage curve was measured, according to archimedes's principle, by covering the undisturbed clods ...
متن کاملUniversal Spatial Correlation Functions for Describing and Reconstructing Soil Microstructure
Structural features of porous materials such as soil define the majority of its physical properties, including water infiltration and redistribution, multi-phase flow (e.g. simultaneous water/air flow, or gas exchange between biologically active soil root zone and atmosphere) and solute transport. To characterize soil microstructure, conventional soil science uses such metrics as pore size and ...
متن کاملInterspecific variation in persistence of buried weed seeds follows trade‐offs among physiological, chemical, and physical seed defenses
Soil seedbanks drive infestations of annual weeds, yet weed management focuses largely on seedling mortality. As weed seedbanks increasingly become reservoirs of herbicide resistance, species-specific seedbank management approaches will be essential to weed control. However, the development of seedbank management strategies can only develop from an understanding of how seed traits affect persis...
متن کاملSeasonal Variation in Weed Seedbank in the Rice Field Soils of Muda Area, Peninsular Malaysia
An investigation was carried out at the Muda rice fields, Peninsular Malaysia during four consecutive seasons of 2004 and 2005 to study the seasonal variation in the weed seedbank. Species composition with their dominance ranking and similarity between the species were recorded. A total of 577 seeds/sample (3337 seeds/m ) in 1/2004, 970 seeds/sample (5659 seeds/m ) in 2/2004, 928 seeds/sample (...
