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 ...

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.

How phagocytic cells kill bacteria: Lessons from a professional killer

FEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

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,

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Determinants of smallholder farmers’ soil acidity perceptions and management practices in the Akuma Watershed, Southwestern Ethiopia

Discover Environment
Soil acidity is a major constraint to agricultural productivity in the humid and sub-humid highlands of Ethiopia, where high rainfall, continuous cultivation, and nutrient depletion are commonly linked with land degradation.
