Effect of dissolved oxygen and chemical oxygen demand to nitrogen ratios on the partial nitrification/denitrification process in moving bed biofilm reactors [PDF]

, 2011
Partial nitrification was reported to be technically feasible and economically favorable, especially for wastewater with high ammonium concentration or low C/N ratio.

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Denitrification characteristics of a sulfur autotrophic denitrification reactor

Journal of Hebei University of Science and Technology, 2016
The denitrification characteristics of a sulfur autotrophic denitrification reactor are investigated. The results show that domestication of sulfur autotrophic bacteria is completed within 15 days after biofilm formation in the reactor, which is shorter than other similar researches.

Does rotational bale grazing affect the distribution of soil nutrients across pastures?

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Rotational bale grazing (RBG), the strategic feeding of round hay bales directly on pasture with controlled access, offers an alternative to continuous winter hay feeding in a single paddock. This study evaluated RBG's potential to redistribute nutrients by increasing soil concentrations in field areas with lower phosphorus (P) and potassium ...

Assessing the Impact of Nitrogen Trade‐Off Between Coffee Tree Productivity and Bean Sensory Attributes to Produce Australian ‘Specialty Coffee’

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.
Effective nitrogen management is essential for sustainable coffee production and enhanced yield. This study evaluated the effects of five nitrogen application rates (per annum; N1: 120 kg/ha, N2: 240 kg/ha, N3: 360 kg/ha, N4: 480 kg/ha, N5: 600 kg/ha) applied in equally distributed monthly rates over 2 years, from flowering to harvest, on Coffea ...

Removal of Aluminum Nitride from Secondary Aluminum Ash and its Aluminum Recovery

Kuangchan zonghe liyong
The aluminum nitride in the secondary aluminum (Al) dross release ammonia gas when it contacts with water. Therefore, the aluminum nitride poses a serious security threat to the environment. Denitrification is an important way to realize the harmless and

An Integrated Assessment of European Soil Health and Restoration Potential

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT Soils host a significant proportion of biodiversity on Earth providing ecosystem functions vital to human well‐being, making it imperative to include them and their ecological features when addressing sustainability goals. We performed a comprehensive assessment of soil health across Europe by explicitly integrating biotic and abiotic ...

Production of N2O in grass-clover pastures [PDF]

, 2002
In organic as well as conventional dairy farming, grass-clover pastures is an important component of the cropping system. This is because grass-clover is an excellent cattle fodder, and because clover has the ability of fixing atmospheric N2.

On‐Farm Slurry Treatment With Bacterial–Enzymatic Bioactivators Reduces Air Pollution in a Pig Growing Unit

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT Intensive pig production systems generate large volumes of slurry, which represent a major source of ammonia emissions and environmental pollute. On‐farm strategies capable of improving slurry quality and reducing gaseous emissions are therefore increasingly needed.

Mesoscale and Submesoscale Variability in the Indian Ocean

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Material transport and air‐sea coupling dynamics associated with monsoon‐related mesoscale and submesoscale processes in the Indian Ocean significantly modulate biogeochemical cycles, the large‐scale energy balance, and both regional and global climate change.
