Soil Surveys and Soil Analyses
The Journal of Agricultural Science, 1911 In undertaking a survey of the soils of a given district the methods of analysis and the classification to be adopted (which in its turn shapes the scheme of the work) must be determined by the purpose before the investigator at the outset. His end may be scientific–to assign the soils in question to their types, or practical–to give information to the

Oedometric study of dredged marine soils admixed with sand for settlement reduction [PDF]
, 2017 Dredged marine soils (DMS) can be reused as fill materials for land reclamation project other than dump back to the open sea. However, in Malaysia, dredged marine soils were considered as a geowaste because of it has poor engineering properties.

Influence of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica [PDF]
, 2014 Archaea are the least understood members of the microbial community in Antarctic mineral soils. Although their occurrence in Antarctic coastal soils has been previously documented, little is known about their distribution in soils across the McMurdo Dry ...

Effect of sieving on ex-situ soil respiration of soils from three land use types [PDF]
, 2020 This study aims to investigate the effect of sieving on ex situ soil respiration (CO2 flux) measurements from different land use types. We collected soils (0–10 cm) from arable, grassland and woodland sites, allocated them to either sieved (4-mm mesh ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
FEBS Open Bio, EarlyView.We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...
