Bulk Densities of Brazilian Amazon Soils Related to Other Soil Properties

Soil Science Society of America Journal, 1998
Abstract The results of this study provide the first baseline for predicting D b from soil properties for soils across the Amazon basin. Bulk density values are needed to convert nutrient content and organic carbon (OC) content to weight of nutrient and ...

Effects of Afforestation on Soil Bulk Density and pH in the Loess Plateau, China [PDF]

, 2018
Sustainable land management requires a clear understanding of the changes in soil quality. In exploring whether afforestation has the potential to improve the soil quality in China’s Loess Plateau, soil bulk density ( ρ s ) and pH were ...

SOIL BULK DENSITY AS RELATED TO SOIL PARTICLE SIZE DISTRIBUTION AND ORGANIC MATTER CONTENT [PDF]

Poljoprivreda, 2003
Soil bulk density is a dynamic property that varies with the soil structural conditions. The relationships between some soil physical and chemical properties such as, clay content (C), silt content (Si), sand content (S), very fine sand content (Vfs ...

SOIL RESPIRATION AND BULK DENSITY UNDERORGANIC AND CONVENTIONALFARMINGSYSTEMS

COLLOQUIUM AGRARIAE, 2018
The aim of this study was to evaluate, in the field, the soilrespiration and bulk density underconventional and organic farming plots. The evaluations were made in different plots established as conventional farming system and organic farming system with six, nine, twelve, fifteen, eighteen and twenty one months old.

Influence of Saturated Organic Matter on the Accuracy of In-Situ Measurements Recorded with a Nuclear Moisture and Density Gauge

Croatian Journal of Forest Engineering, 2021
The impact of machines on forest soils is regularly assessed and quantified using absolute bulk density, which is most frequently obtained by soil cores. However, to allow for repeated measurements at the exact same locations, non-destructive devices are

PEDO-TRANSFER FUNCTIONS FOR ESTIMATING SOIL BULK DENSITY IN CENTRAL AMAZONIA

Revista Brasileira de Ciência do Solo, 2015
Under field conditions in the Amazon forest, soil bulk density is difficult to measure. Rigorous methodological criteria must be applied to obtain reliable inventories of C stocks and soil nutrients, making this process expensive and sometimes unfeasible.

Soil bulk density assessment in Europe

Agriculture, Ecosystems & Environment
The topsoil Land Use and Cover Area frame Statistical survey (LUCAS) aims at collecting harmonised data about the state of soil health over the extent of European Union (EU). In the LUCAS 2018 survey, bulk density has been analysed for three depths, i.e., 0–10 cm = 6140 sites; 10–20 cm = 5684 sites and 20–30 cm =139 sites.

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 ...
