In urban catchments of arid central Arizona, we investigate how the export of mineral and organic nitrogen (N) in storm runoff is regulated by interactions between local landscape characteristics and broader scale storm features. First, we test whether N export is more a function of (1) processes that affect N concentration in runoff or (2) the propensity of the catchment to convey rainfall as ...

Maintaining ground cover of forages may reduce the export of nitrogen (N) from pastures. The objective of this work was to determine the effect of ground cover on N export from pastured riparian areas receiving simulated rainfall. Plots were established on two adjacent sites in the North Carolina Piedmont: one of 10% slope with Appling sandy loam soils and a second of 20% slope with Wedowee san...

postharvest losses are a limiting factor on storage life of many vegetables and fruits including citrus. therefore a study was conducted to evaluate the effects of thermal treatments and herbal thyme oil spray on sanguinello blood oranges in golestan province in the northern part of iran. the tests have been performed one day after harvesting, under four different treatments: hot water at 55˚c ...

the aim of this research is to develop a model of antecedents and consequences of iran exemplary exporters’ competitive intelligence (ci) in order to identify their strengths and weaknesses. for this purpose we discuss position and growth strategies of exporters, effective use of ci, export competitiveness enhancement and sustainable export development. based on conceptual model, knowledge mana...

abstract having no exact knowledge of most appropriate harvesting time in kiwifruit grown in different regions of guilan province, as well as the low storage longevity of the fruits are the most important factors causing considerable reduction in both marketability and export affairs. in this study, the influence of fruit quality in term of harvesting time on the postharvest quality and food va...
