Visualizing Mineral-Associated Organic Matters in Long-Term Fertilization Treated Soils by NanoSIMS and SR-FTIR

open access: yesFrontiers in Soil Science, 2022
Formation of mineral-associated organic matters is essential for long-term soil organic carbon preservation. However, the regulation pathways of mineral-associated organic matters in soils remains largely undescribed, especially at the submicron scale ...

Organic matter matters for ice nuclei of agricultural soil origin

open access: yes, 2014
. Heterogeneous ice nucleation is a crucial process for forming ice-containing clouds and subsequent ice-induced precipitation. The importance for ice nucleation by airborne desert soil dusts composed predominantly of minerals is widely acknowledged ...

Plant rhizodeposition: A key factor for soil organic matter formation in stable fractions

open access: yesScience Advances, 2021
Rhizodeposition and roots play opposite but complementary roles for building mineral-associated and particulate organic carbon. Soil organic carbon formation remains poorly understood despite its importance for human livelihoods. Uncertainties remain for

Bacterial Selection from Shrimp Ponds for Degradation of Organic Matters [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2007
Accumulation of ammonia, nitrite and hydrogen sulfide in a shrimp pond is generally caused by incomplete degradation of residual organic matters from overfeeding and from organic wastes released by shrimps.

Triplet-State Photochemistry of Dissolved Organic Matter: Triplet-State Energy Distribution and Surface Electric Charge Conditions.

open access: yesEnvironmental Science and Technology, 2019
Excited triplet states of chromophoric dissolved organic matter (3CDOM*) are highly reactive species in sunlit surface waters and play a critical role in reactive oxygen species (ROS) formation and pollutant attenuation. In the present study, a series of

Ecological networks of dissolved organic matter and microorganisms under global change

open access: yesNature Communications, 2022
Microbes regulate the composition and turnover of organic matter. Here we developed a framework called Energy-Diversity-Trait integrative Analysis to quantify how dissolved organic matter and microbes interact along global change drivers of temperature ...

A Comprehensive Review on Water Quality Parameters Estimation Using Remote Sensing Techniques

open access: yesItalian National Conference on Sensors, 2016
Remotely sensed data can reinforce the abilities of water resources researchers and decision makers to monitor waterbodies more effectively. Remote sensing techniques have been widely used to measure the qualitative parameters of waterbodies (i.e ...
