ESTIMATION OF RADON EMANATION COEFFICIENT FOR REPRESENTATIVE SOILS IN OKINAWA, JAPAN

, 2015
Radon (222Rn) emanation coefficients for the representative soils distributed in Okinawa Island, Japan, have been estimated empirically. Arithmetic means of the emanation coefficients for dry and moist conditions were calculated to be 0.19 and 0.29 ...

Characteristics of Runoff and Sediment Yield in a Simulated Hedgerow–Grass Ditch System in Sloping Lands with Regosols

Land
The independent effects of hedgerow or grass ditches on the migration of runoff, sediment and nutrients are well known; however, the effects of combined hedgerow–grass ditch systems have rarely been assessed.

Characterization of representative soils from the confluence of Pereschivul mic with Pereschivul mare

, 2016
The studied area belongs to Tutova Rolling Hills. The geological substrate consists of recent and loose deposits belonging to Kersonian, Meotian, Pontian, Dacian and Romanian, predominantly with sands and clay infilled. These deposits are bisected by a

Vegetation, soils, and humus forms of Sardinian holm oak forests and approximated cross-harmonization of vegetation types, WRB Soil Groups and humus forms in selected Mediterranean ecosystems

, 2017
Five plant communities, related to elevation above sea level and geological substrata, are recognized in the holm oak forests of Sardinia (Italy). These forests show a considerable inhomogeneous structure due to present day and past uses.
