The impact of transport infrastructure on ecological status of arable land in Western Siberia

Abstract

The use of deicing compounds and car exhaust have a negative impact on the main indicators of arable fertility.The purpose of the research was to study the physical properties of arable land and crop yields at different distances from the roads. Four soils were studied: sod-podzolic, gray forest, leached chernozem and meadow saline. Soil sampling was carried out along the Tyumen - Omsk and Tyumen - Khanty-Mansiysk highways. It was found that at a distance of 10 meters from the highway structural and aggregate composition of high-humus soils differs from the control, located 200 meters. At a distance of 50 meters or more from the road, physical indicators of arable land come back to normal. The sections adjacent to the roads up to 10 meters wide are overfilled to 1.57 g/cm3, which in the conditions of Western Siberia can cause surface waterlogging. The annual loss of grain from the negative impact of transport infrastructure on the site length of 1 kilometer and a width of 20 meters on leached chernozem is 5.0 tons. At market grain prices in the amount of $140, the annual loss of farmers corresponds to $1400 for each kilometer of the road passing through the chernozem fields.
