Understanding the factors (salinity, nitrate, and carbon availability) and mechanisms that control N2O products and nitrate removal patterns in inland saline farmland ditches

open access: yesVadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Denitrification, the microbial process by which nitrate (NO3−) in aquatic systems is converted to N2 and N2O, is widely recognized as an effective and environmentally friendly method for mitigating NO3− pollution in water bodies. However, the complex role of salinity, which could significantly influence the denitrification process, in salt ...

The use of high altitude remote sensing in determining existing vegetation and monitoring ecological stress [PDF]

open access: yes
High altitude color and multispectral black and white photography was used to survey existing vegetation and soil conditions on the Empire Ranch where large scale development will soon begin. Utilizing stereo pairs of the high altitude color photography,

Beyond universal application: dissecting the differential amelioration and carbon sequestration performance of biochar in chloride-, sulfate-, and soda saline-alkali soils

open access: yesGeoderma
Biochar is widely recommended for ameliorating saline-alkali soil and enhancing soil organic carbon. However, its efficacy across different saline-alkali soils (chloride, sulfate, and soda-types) remains unclear.

Abh, AbrB3, and Spo0A play distinct regulatory roles during polymyxin synthesis in Paenibacillus polymyxa SC2

open access: yesMicrobiology Spectrum
Polymyxins exhibit antibacterial activity against various gram-negative bacteria. However, the regulatory mechanisms of polymyxin synthesis remain unclear. Here, Abh, AbrB3, and Spo0A of Paenibacillus polymyxa SC2 were found to bind to P pmx via DNA pull-

Thermodynamic Constraints on H2 Production and Habitability From Mg‐Rich Serpentinites as Mars Analogs

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Serpentinization produces hydrogen and methane through abiotic water‐rock interactions, potentially supporting chemotrophic life in planetary subsurface environments. Serpentine deposits in the Martian Noachian landscapes of Nili Fossae and the Southern Highlands have been considered as potential paleo‐habitable zones. However, the geochemical

Précipitation de la fluorine et contrôle géochimique du calcium dans des sols alcalins du Niger : conséquences pour une estimation quantitative de l'évolution géochimique des sols [PDF]

open access: yes, 1995
La précipitation de la fluorine a été identifiée dans des sols alcalins non salés du Niger. Celle-ci renforce le contrôle géochimique du calcium initié par la précipitation de la calcite.

Soil Texture and Chemical Properties Influence Arbuscular Mycorrhizal Fungi Abundance, Diversity, and Richness in East African Rangelands

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT Rangeland degradation in East Africa threatens soil biodiversity. Yet the diversity of native arbuscular mycorrhizal fungi (AMF) remains underexplored in this region, despite their central role in nutrient cycling, soil aggregation, and ecosystem functioning.

Restoration of Soil Health for Achieving Sustainable Growth in Agriculture [PDF]

open access: yes
Total geographical area of Pakistan is 79.61 million hectares (m.ha.). Area under cultivation is 21.59 m.ha.; of which, only 5.34 m.ha. (i.e., 25 percent) is free from soil limitations and is fit for intensive agriculture [Mian and Mirza (1993)].
