Influence of urea and ammonium sulfate on soil acidity indices in lowland rice production. [PDF]

, 2010
Urea and ammonium sulfate are principal nitrogen (N) sources for crop production. Two field experiments were conducted during three consecutive years to evaluate influence of urea and ammonium sulfate application on grain yield, soil pH, calcium (Ca ...

Long-term nitrogen deposition does not exacerbate soil acidification in tropical broadleaf plantations

Environmental Research Letters, 2021
Nitrogen (N) deposition induces soil acidification in natural forests; however, whether it increases soil acidity in tropical plantations with simple tree structures compared with natural forests remains unclear.

Soil acidity correction and fertilization strategies: Effects on acidity, nutrient availability, and crop yield [PDF]

Revista Brasileira de Ciência do Solo
High soil acidity and low nutrient availability in the deeper soil layers of no-tillage systems (NTS) can restrict crop yield potential. This study aimed to evaluate the impact of different soil acidity correction strategies and P and K application ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Assessing the Spatial Variability of Soil Acidity in Assosa District, Northwestern Ethiopia

Applied and Environmental Soil Science
Soil acidity negatively affects agricultural productivity, biodiversity, and food security in the tropical and subtropical regions. It exhibits significant spatial variability arising from natural soil-forming processes and anthropogenic factors.

Results of the study of pH and organic matter in the surface soil of Ulaanbaatar

Proceedings of the Mongolian Academy of Sciences, 2021
This work summarizes the results of a study into such important urban soil parameters as soil actual (pH) and potential acidity (pH) and soil organic matter content (SOM) in the surface soil of Ulaanbaatar. The soil pH in Ulaanbaatar is slightly alkaline,
