EFFECTS OF COMPACTION DUE TO MACHINERY TRAFFIC ON SOIL PORE CONFIGURATION

effect of sugarcane harvest machinery traffic on soil compaction in south west of khuzestan

in order to study the effects of sugar cane harvest machinery traffic on bulk density and cone index variation, a survey was conducted in 10 farms of deabel khozaiee sugarcane agro-industrial company, ahvaz, in 2006. in this experiment, two types of harvesters including wheel half track and tire wheels with 14 tons of weight, versus two types of tractor and basket transporters, with 10 and 18 t...

Soil Compaction: Effects and Amelioration

Soil compaction was identified as the cause of ‘growth stunting disease’ in sultana grapes and ‘red death’ in cotton at the Lower Orange River and Vaalharts irrigation schemes. In an experiment growth stunting disease was eradicated completely and yields of sultanas increased substantially by deep cultivation, which eliminated compacted soil layers. Ripping increased the quality of tobacco, and...

Valuing Reduction of Risk of Mortality Due to Traffic Accidents

Background and Aim: The trade-off between monetary wealth and fatal safety risks is explained by the value of statistical life, an efficient tool widely used to evaluate projects and allocate appropriate resources for road safety. The objective of this study was to estimate the statistical significance of life in order to improve road safety in the city of Ardabil, Iran. Materials and Methods:...

Environmental Effects of Skidder Traffic and Skidding Directions on Forest Soil Compaction and the Regeneration Establishment Condition in Choob-e- Farim Forests

 Forest soil compaction influenced by the use of skidders machineries, its power and weight, then causes changes on specific physical characteristics of soil. In most of the investigations, the negative effects of skidder traffic is reduction in growth of trees. The aim of this research was investigating the effects of number of skidder traffic in different skidding direction (uphill and downhi...
