Performance of perennial ryegrass (Lolium perenne L.) seed crops under water stress conditions

Creator:: Velloza, Theodosius Marmaduke
Abstract:: Summer drought is a major factor limiting the regrowth of perennial ryegrass seed crops. This phase of crop development has a strong influence on seed yield because most of the tillers that contribute towards next season's seed crop are produced or regrown during this period. In recent years many seed...

Phosphorus availability in biosolids-amended soils

Creator:: Choate, Jeff
Abstract:: Quantifying labile phosphorus (P) pools in biosolids is needed to manage biosolids for both agronomic and environmental purposes. Phosphorus indices originated in an effort to protect surface water quality from-non-point-agricultural P inputs. The objectives of this research were to: (1) evaluate soil test components of the western Oregon P index...

Biochars as a potting amendment in greenhouse nurseries: How to eliminate unwanted ethylene emissions

Creator:: Fulton, Will, Gray, Myles, Prahl, Fredrick, and Kleber, Markus
Abstract:: Biochars have potential value for greenhouse nurseries as a potting amendment, reducing the need for environmentally costly products currently in use. The onsite manufacture of biochars by pyrolysis of woody waste offers additional greenhouse value as a source of clean heat. However, recent work observed that some biochars may evolve...

From atmospheric winds to fracture ventilation: Cause and effect

Creator:: Nachshon, Uri, Dragila, Maria, and Weisbrod, Noam
Abstract:: Vadose zone fractures and soil cracks exposed to the atmosphere have an impact on gas exchange processes at the Earth-atmosphere interface. In this study we explored and quantified the role of ground-surface winds on fracture ventilation. While the governing physical mechanisms that cause ventilation are relatively well understood, this is...
