To determine and evaluate the soil structure in situ conditions, a lot of research methods have been proposed. However, ascertaining the applicability of these methods to soils of entirely different “types of structure,” which they can express and evaluate, is still a point of debate. With th...
Field and laboratory methods A total of 200 surface soil samples (0–15 cm) were collected using a simple handheld trowel50. Vegetation was gently scraped aside and ~150 g of soil was placed in a sealed plastic bag for transport to the laboratory. Each collection location was geo-locate...
With soil test data, the problem of identification is twofold. Not only does the field from which the sample was taken need to be identified, but the particular test and units used by the laboratory where the sample was processed must also be known. With a sample's field identification, th...

and accurate applied strategy, a simple 27 kg C m−3average carbon mass assumption, we estimate 0.72 (Pg) of C for the top 1 meter of soil. SSURGO soils maps do not perfectly overlap mapped tidal wetlands because of missing or incomplete survey data; overlapping area covered 1.97 ...
Some of the methods use introduced, and not intrinsic, species. The benefit of this is a higher degree of standardisation, as the species used in these bioassays is easy to maintain in laboratory cultures compared to naturally occurring species. The drawback may be that their ecological ...
The United States National Cooperative Soil Survey Program has prepared soil maps for much of the country. Both field and laboratory data are used to design map units and provide supporting information for scientific documentation and predictions of soil behavior. Coordination of mapping, sampling site...
It talks about various methods of obtaining chemical information about a field that do not involve physically taking a sample to the laboratory. There are two phases to soil sampling, a field sampling phase and a laboratory sampling phase. Field sampling, sample transport, and laboratory sampling ...
