THE EFFECT OF TURNING FREQUENCY ON SOME COMPOST QUALITY [PDF]

Journal of Agricultural Chemistry and Biotechnology, 2010
Composting of organic materials (chicken manure mixed with sawdust) was performed using turned windrow method. The aim was to investigate the effect of turning frequency on some physicochemical properties of the final product of organic materials.

Geogenic organic carbon in terrestrial sediments and its contribution to total soil carbon [PDF]

SOIL, 2021
Geogenic organic carbon (GOC) from sedimentary rocks is an overlooked fraction in soils that has not yet been quantified but influences the composition, age, and stability of total organic carbon (OC) in soils.

Losses of soluble forms of organic carbon in relation to different agro-technical treatment of meadows

Soil and Water Research, 2016
Studies were performed to determine the loss of soluble forms of organic carbon in differently used meadows on mineral soil. In a long-term experiment two variants were distinguished: a productive meadow (N120-AN and N120-CN) and a non-productive one (Kp-

Carbon dynamics in no-till soil due to the use of industrial organic waste and mineral fertilizer

Revista Ciência Agronômica
The use of organic waste from industrial processes in agriculture is a strategy not only for improving soil properties but also for promoting the utilization of recycled nutrients by market crops and for reducing environmental impact.

Determination of Total Organic Carbons by Ion Chromatography

Analytical Sciences, 1991
A method for indirect UV detection of carbonate in solution using potassium phthalate as eluent has been developed. The detection limit for carbonate is 0.5mg/l in solution. The application of the analytical method developed to the analysis of trace organic carbon in deionised water and total carbon in air particulate was investigated and the results ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
