Atmospheric deposition of nitrogen and sulphur in relation to critical loads of nitrogen and acidity in the Czech Republic
acidity atmospheric deposition
2015/3/3
Estimates of dry and wet deposition of sulphur and nitrogen were compared with critical loads of sulphur
and nitrogen in the Czech Republic on 1 ×1 km grid. Deposition was estimated from monitored a...
Exhaust Characteristics and Loads of Fertilizer Nutrients in the Drainage from a Golf Course
Amount of exhaust water from golf course Drainage from golf course Environmental effluent load
2009/7/29
We researched the amount of chemical fertilizer used on a golf course, fertilizer nutrients and flows in the drainage from the golf course every 4 or 8 days during the period from June 1993 to May 199...
Comprehensive Evaluation of Productivity and Environmental Loads in a Paddy Field Under Different Fertilized Conditions
Comprehensive evaluation environmental load
2010/12/2
The effect of fertilized conditions on environmental loads of methane emissions and water quality in a paddy field and the yield of rice were comprehensively evaluated. The experimental plots were no-...
Modelling the effects of repeated wheel loads on soil profiles
compaction wheel loads soil strength finite element modelling
2008/11/26
Compaction of soil caused by increasing mechanical loads and repeated wheeling may result in reduced soil productivity. The physical response of soils to such loading is analysed with a non-linear fin...
Comparison of loads on smooth and corrugated-wall model grain bins
wheat bins silos loads friction
2008/11/21
Wall and floor loads exerted by wheat on a corrugated-wall model bin were measured. The 7.3 m high bin with a diameter of 2.44 m was centrally filled with wheat. Tests were conducted for a filling he...
Fatigue strength of wheat grains. Part 1. The analysis of grain deformation at multiple loads
multiple loads grain deformation
2008/11/21
In the majority of studies concerning the evaluation of grain resistance, the authors usually make use of the method of visual evaluation of grain condition - with respect both to external and interna...
Effects of grain properties on loads in model silo
grain silo mechanical properties silo loads
2008/11/19
This work addresses the variation in wall loads in thin, smooth walled, flat floor metal silos caused by the variation in the mechanical properties of the grain bedding and friction forces acting on t...
Estimation of physical results of percussive loads in wheat and triticale seed
seed damage impact triticale wheat
2008/11/19
This paper contains the evaluation of the physical effects of impact loads on wheat grain and triticale one. One level of kinetic energy (15 mJ) exerted on the tested grain had already been establishe...
Wall flumes are vertical conduits attached to the walls of grain bins through which grain can flow. Flumes are thought to encourage funnel flow throughout the height of the bin while reducing the dyna...
Wear-in effects on loads in cylindrical and conical modelgrain bins
wheat loads friction bin
2008/11/10
The vertical wall and floor loads exerted by soft red winter wheat on flat-floor model bins are compared for cylindrical and conical shape bins. The change in the inclination of the bin wall from 0?to...
Abatement costs for agricultural nitrogen and phosphorus loads: a case study of crop farming in south-western Finland
water pollution agriculture abatement nitrogen phosphorus nutrient load
2010/8/10
Designing efficient agri-environmental policies for agricultural nutrient load reductions calls for information on the costs of emission reduction measures. This study develops an empirical framework ...
QUANTITATIVE TRENDS IN AIRBORNE LOADS OF CELTIS SINENSIS POLLEN AND ASSOCIATIONS WITH METEOROLOGICAL VARIABLES IN A SUBTROPICAL AUSTRALIAN ENVIRONMENT
atmosphere Ulmaceae Celtis sinensis pollen
2010/12/24
Celtis sinensis is an introduced plant species to the southeastern region of Queensland that has had a destructive affect on indigenous plant communities and its pollen has been identified as an aller...
