Sentence examples for soil polygon from inspiring English sources

For the three C pools investigated, model simulation provided a regional estimate, while forest inventory, plot, and soil polygon data provided an estimate of the spatial variation.

There are several limitations in this kind of mapping approach that relate to the original intent of the soil survey, the effect of mapping scale, and the nature of soil polygon boundaries.

Aboveground biomass, forest floor, and soil carbon (C) stocks were estimated for a transitional boreal region in western Alberta using available forest inventory data, model simulation, field observed plot data, and soil polygon (area averaged) information from the Canadian soil organic carbon database (CSOCD).

Single-component soil polygons from conventional soil survey maps of the Langley Vancouver Map Area, British Columbia Canadaa), were used to generate randomized training points for 9 parent material classes.

The SGDBE holds information on dominant and secondary land use types of each component STU of the soil map polygons.

For regional soil studies where polygon mapping and soil point data are available, ensemble modelling is a useful combinatorial approach.

Using GIS tools, we analyzed the contents (richness) of soil mapping units (polygons) with regard to vegetation series and bioclimatic belts as well as the contents of vegetation series and bioclimatic belts with regard to SMU.

Published average N2 fixation rates were adjusted using variations in crop yield, and the total amount of N2 fixed was estimated at the Soil Landscape of Canada polygon level (1 1,000,000) and then scaled up to provincial and national levels.

On the basis of the values of the combined-digital data fields (soil types+vegetation of basic polygons of the basic map+special restrictions arising from mesochore type or CORINE land use type) defined using theoretical and field observation data, queries were made to ascertain the distribution of natural VSTs.

In a field study conducted in polygonal tundra in Siberia, it was found that vascular plants had a greater effect on CH4 emissions by enhancing CH4 oxidation at the elevated polygon-rim (water table 35 39 cm below soil surface), whereas in the polygon-centre (water table 0 4.5 cm below soil surface) CH4 transport and root exudation were dominant mechanisms [ 48].

The relatively stable, nonpolygonal soils have thicker horizons and so higher PDI values as compared to the soils of sorted polygons, suggesting that soil properties show the intensity of disturbance.
