Biochar and Sediment Amendments Alter Soil Nitrogen Mineralization: Microbial Biomass and Extracellular Enzyme Activity

GCB Bioenergy, Volume 18, Issue 7, July 2026.
Co‐application of Mn‐modified biochar and fishpond sediment markedly improves soil pH, organic carbon, microbial biomass, and nitrogen mineralization, demonstrating a synergistic effect that enhances soil fertility, microbial activity, and nutrient cycling for sustainable agricultural management.

Biochar‐Based Urea Enhances Yield and Quality of Lady's Finger (Abelmoschus esculentus L.): A Pathway Towards Sustainable Nitrogen Management

GCB Bioenergy, Volume 18, Issue 7, July 2026.
Biochar‐coated urea markedly improved growth, yield, nitrogen‐use efficiency, and nutritional quality of lady's finger compared with conventional urea. This biochar‐based slow‐release fertilizer offers a sustainable pathway to reduce nitrogen losses, enhance productivity, and improve economic returns while mitigating environmental degradation ...

Herbage Accumulation, Persistence and Nutritive Value of C4 Grasses Grown Across Temperate Environments in South‐Eastern Australia

Grass and Forage Science, Volume 81, Issue 3, July-September 2026.
ABSTRACT Climate modelling has projected increasing temperatures and a shift in rainfall systems in southern Australia, suggesting an increase in the summer–autumn feed gap of pasture systems based on temperate species. Tropical (C4) pasture species may diversify the feed base and help mitigate climate variability in these areas.

Combined Effects of Water Shortage and CO2 Enrichment on Yield and Water Use Properties of Barley (Hordeum vulgare L.) Genotypes

Journal of Agronomy and Crop Science, Volume 212, Issue 4, July 2026.
ABSTRACT A selection of winter barley genotypes was investigated for their responses to water shortage under different CO2 concentrations in a greenhouse. The experiment was conducted in a 2*2 factorial design. Plants were grown either with optimum water supply or simulated drought in the BBCH 59 stage at current (~400 ppm CO2) or elevated CO2 ...

Direct Competitive Kinetic Isotope Effect Measurement Using Quantitative Whole Molecule Matrix‐Assisted Laser Desorption Ionization Time‐of‐Flight Mass Spectrometry

ChemBioChem, Volume 27, Issue 12, 26 June 2026.
Kinetic Isotope effect (KIE) measurements are a powerful tool to interrogate enzyme mechanisms and transition state structures. In this study, we develop a simple quantitative MALDI‐TOF mass spectrometry approach to measure competitive heavy atom KIEs.

Nature of Humic Acids

Nature, 1963
THE idea that humic acids are heteropolycondensates1 of phenolic substances with or without the participation of amino-acids is now widely accepted. Three possible sources of the phenols are postulated: (1) phenolic materials such as flavonoids leached from the plant debris; (2) phenolic units formed during the decomposition of lignin; (3) phenolic ...

Desmutagenic effect of humic acid

Mutation Research, 1986
In the present study, humic acid was not found to be mutagenic and did not inhibit spontaneous mutation. It did, however, inhibit the mutagenicities of benzo[a]pyrene and 3-aminoanthracene (+S9 mix), but not the mutagenicities of 4NQO, AF-2 and MNNG (-S9 mix).

Iodide binding by humic acid

Environmental Toxicology and Chemistry, 1991
Abstract Iodide binding by humic acid was studied. The reaction was dose, temperature and pH dependent. A maximum binding of 88% was reached with 2 mg humic acid in 0.15 M Tris buffer. The efficiency of iodide binding by the buffer becomes higher whenever the buffer is slightly alkaline.
