A planar-source method, initially designed to obtain diffusion coefficients in compacted clay, is adapted here to determine the apparent diffusion coefficient (Da) of radiostrontium in soils representative of the Spanish territory.
Therefore, in this study we evaluated the effects of pelletized ashes on the chemical and microbiological properties of four soils representative for the central Alps [rendzic Leptosol (L), fibric Histosol (H), haplic Podzol (P), and dystric Cambisol (Cm)] in a microcosm trial during 22 weeks.
A new monitoring scheme is urgently needed and should cover large blocks of land representative of the soil landscapes of England and Wales.
"If the people of Massachusetts do not want that terrorist to be buried on our soil," declared Representative Edward J. Markey, a Democratic candidate for the U.S. Senate, "then it should not be".
Acidic characters of the soil are representative of the soil cover found in the hills.
The acquisition of precise soil data representative of the entire survey area, is a critical issue for many treatments such as irrigation or fertilization in precision agriculture.
Given the high inter-annual variability in soil erosion, representative measurements are best carried out over time scales of a few decades.
Our mechanistic model is able to accurately predict A. caliginosa distribution and abundance in spatially heterogeneous soil profiles representative of field study conditions.
For this activity, we made two digital images of each of our fossil skulls taken from different views and used Photoshop to create transparencies which were placed on PowerPoint slides with background soil colors representative of the location where the fossil was found in Africa.
By using parametric/non-parametric correlations and multivariate statistical analysis, this study compares the statistical distribution of the BFI over 1079 soil samples representative of various environmental contexts in Italy with 8 alternative indicators formulated according to different aggregation rules and weighting techniques of the 6 variables composing the BFI.
