Global stocks and capacity of mineral-associated soil organic carbon

Nature Communications, 2022
Soil is the largest terrestrial reservoir of organic carbon and is central for climate change mitigation and carbon-climate feedbacks. Chemical and physical associations of soil carbon with minerals play a critical role in carbon storage, but the amount ...

A critical review of mineral–microbe interaction and co-evolution: mechanisms and applications

National Science Review, 2022
Mineral–microbe interactions play important roles in environmental change, biogeochemical cycling of elements and formation of ore deposits. Minerals provide both beneficial (physical and chemical protection, nutrients, and energy) and detrimental (toxic

Pyrite oxidation under initially neutral pH conditions and in the presence of Acidithiobacillus ferrooxidans and micromolar hydrogen peroxide [PDF]

, 2012
Hydrogen peroxide (H2O2) at a micromolar level played a role in the microbial surface oxidation of pyrite crystals under initially neutral pH. When the mineral-bacteria system was cyclically exposed to 50 μM H2O2, the colonization of Acidithiobacillus ...

Mineral Exploration Funds [PDF]

, 1968
While independent mineral operators have traditionally been confronted with a scarcity of risk capital for mineral development, willing investors have often experienced equal difficulty in locating responsible mineral operations in which to invest.

Forage herbs improve mineral composition of grassland herbage [PDF]

, 2011
Provision of an adequate mineral supply in the diets of ruminants fed mainly on grassland herbage can present a challenge if mineral concentrations are suboptimal for animal nutrition.

Mineral maturity and crystallinity index are distinct characteristics of bone mineral [PDF]

, 2010
The purpose of this study was to test the hypothesis that mineral maturity and crystallinity index are two different characteristics of bone mineral. To this end, Fourier transform infrared microspectroscopy (FTIRM) was used.

Mineral Nutrition

Abstracts, 2019
Seventy trials evaluated preplant broadcast and banded P or K fertilization (35 P trials and 35 K trials). Replicated, complete block designs were used. Foliar and soil P or K fertilization increased (P < 0.05) yield in 20 trials.
