Trucking Restrictions Eased To Expedite Transport Of State’s Freeze-Vulnerable Crops
Trucking Restrictions State’s Freeze-Vulnerable Crops
2010/1/13
Florida Agriculture Commissioner Charles H. Bronson is alerting the state’s agricultural producers that highway restrictions have been eased so that they can quickly harvest and transport crops that a...

Microbial transport in soil caused by surface and subsurface drip irrigation with treated wastewater
bacteriophage fecal coliforms irrigation soil wastewater
2008/11/26
The objective of this work was to compare and simulate transport and fate of microorganisms from wastewater for surface and subsurface irrigation methods. Adsorption isotherms and water-content depend...
Concurrent transport of reactive and non-reactive ions in undisturbed soil columns
transport reactive and non-reactive ions soil
2008/11/26
Advective-dispersive contaminant transport in soils continues to be a subject of extensive studies. Transport of conservative tracers, ie non-reactive ions, is mostly affected by soil physical heterog...
Effect of solid phase wettability on water transport and retention in peat enriched soil affected by freezing/thawing
wettability water retention freezing/thawing soil
2008/11/20
Samples of A and B horizons of arable loessial soil, with and without the addition of c.a. 9% of peat and subjected to six freezing/thawing cycles, were studied. Surface free energies and water contac...
Radioactive tracer techniques used in solute transport studies in a field soil
tracer techniques solute velocity longitudinal dispersion coefficient bypassing ratio
2008/11/12
Radioactive tracer techniques were used for in-situ measurements of the solute velocity, longitudinal dispersion coefficient, and bypassing ratio, as well as for estimation of the impact of land-use c...
Transport of manure-borne Cryptosporidium parvum oocysts through saturatedand unsaturated soil columns
Cryptosporidium parvum soil water transport
2008/11/11
Release of manure-borne Cryptosporidium parvum oocysts is the most probable cause of ground and surface water contamination with this pathogen. Our objective was to assess the effect of water saturati...
Wind-caused air transport through greenhouse screens: a physical modelling approach
air exchange porous screen greenhouse wind pressure physical model
2008/11/10
An understanding of the air exchange through screens is needed to optimise climate control strategies in greenhouses. An analysis of the airflow through porous screens due to wind pressure was perform...
