Intense soil erosion in the northern part of Gerecse Hills, Hungary, is causing significant damage to vineyards area. Three Neszmély Wine Region were investigated quantify amount eroded soils. The method was based on monitoring for one-year between July 2019 and June 2020. Every season, a set photographs taken from an unmanned aerial vehicle. images processed photogrammetric workflow produce hi...
The results of long-term observation the foundations temperature regime and dangerous cryogenic processes development near exploited well pads on Yamburg field are presented. Temperature observations (1992-2020) includes data four pads. Influence natural anthropogenic factors permafrost was investigated. Based a great experience observations, thermoerosion gas were characterized. Some considere...
In the literature, mainly particle-size distribution (PSD) analyses in soil catenas, of e.g., moraine and riverine landscapes were discussed. Analysis comparison PSD (ML) ice-dammed lakes (ID-LL) not studied. Since landscape origin has diversified relief is under intensive agricultural use, aspects erosion are great importance. The changes studied 14 catenas (toposequences) eroding soils at upp...
Approaches to restore productivity eroded soils are urgently needed sustain food security. We evaluated plant response soil-landscape rehabilitation, in which approximately 15 cm of topsoil was moved from depositional landscape positions the upper slope. Crop monitored for 6 yr a corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotation at severely site and 4 wheat (Triticum aestivum moderat...
In the unglaciated parts of Southwestern Wisconsin, buried Terra Rossas are commonly found. These clayey, red soils are buried by loess and mainly found on ridges underlain by limestone. They have been eroded during periglacial climates. The red clay has implications for groundwater recharge as well as lateral flow through the landscape. This project focusses on a 50 km2 watershed where some 40...
Because Geno protected area didn’t protect enough, it cause to use lots of part for domestic animal productivity and this ecosystem with special plant and animal species degrade. This study was down with this goal: determining of proper region for soil protection, rehabilitation and special use according dry region potentials. We use these maps: slope, aspect, elevation, soil, plant cover and r...
Erosion means the harvesting, transportation and movement of eroded material .The concept is very extensive erosion that has different definitions in different disciplines. The purposes of this paper is finding a brief definition of “erosion” concept in different perspectives and comparing it in Geomorphologic and Natural Resources point of views. To achieve this goal, we try to use the library...
Runoff P associated with eroded soil is partly solubilized in receiving waters and contributes to eutrophication, but the significance of particulate phosphorus (PP) in the eutrophying P load is debatable. We assessed losses of bioavailable P fractions in field runoff from fine-textured soils (Cryaquepts). Surface runoff at four sites and drain-flow at two of them was sampled. In addition to di...
Soil erosion redistributes soil organic carbon (SOC) within terrestrial ecosystems, to the atmosphere and oceans. Dust export is an essential component of the carbon (C) and carbon dioxide (CO(2)) budget because wind erosion contributes to the C cycle by removing selectively SOC from vast areas and transporting C dust quickly offshore; augmenting the net loss of C from terrestrial systems. Howe...
