Digital mapping of soil pH and carbonates at the European scale using environmental variables and machine learning.

Science of the Total Environment, 2022
Soil pH and carbonates (CaCO3) are important indicators of soil chemistry and fertility, and the prediction of their spatial distribution is critical for the agronomic and environmental management.

Diversity‐stability relationships in temperate grasslands as a function of soil pH

Land Degradation & Development, 2022
Diversity‐stability relationships in grasslands depend on the environment. Climate change and land degradation potentially alter soil pH and community stability within grassland environments, although it remains unclear how alteration in soil pH affects ...

Responses of soil pH to no‐till and the factors affecting it: A global meta‐analysis

Global Change Biology, 2021
No‐till (NT) is a sustainable option because of its benefits in controlling erosion, saving labor, and mitigating climate change. However, a comprehensive assessment of soil pH response to NT is still lacking.

Soil pH and nutrients shape the vertical distribution of microbial communities in an alpine wetland

, 2021
Soil microbial communities are vital for maintaining functions of alpine wetland ecosystems, which have been shown to be sensitive to climate change and anthropogenic disturbances in recent decades.

Alkaline soil pH affects bulk soil, rhizosphere and root endosphere microbiomes of plants growing in a Sandhills ecosystem.

FEMS Microbiology Ecology, 2021
Soil pH is a major factor shaping bulk soil microbial communities. However, it is unclear whether the belowground microbial habitats shaped by plants (e.g. rhizosphere and root endosphere) are also affected by soil pH.

Soil pH Variation Within a Soil. III. pH Variation in Limed Soil

Communications in Soil Science and Plant Analysis, 2004
Abstract There are many methods for determining lime requirement, but no single method is suitable for all soils. A fast and efficient method to evaluate lime effect is needed. Soil buffering capacity tests and column-leaching tests were applied to the limed Van Rockel soil at the depth of 0–30 cm to evaluate pH distribution after liming. Two groups of

Soil pH and temperature regulate assembly processes of abundant and rare bacterial communities in agricultural ecosystems.

Environmental Microbiology, 2020
The factors determining stochastic and deterministic processes that drive microbial community structure, specifically the balance of abundant and rare bacterial taxa, remain underexplored.

Soil pH Variation Within a Soil. II. pH Variation in a Neutral and an Alkaline Soil

Communications in Soil Science and Plant Analysis, 2004
Abstract Soil pH variation exists in particles of every kind of soils, including alkaline soil. The objective of this study was to examine soil pH varia-tion in a neutral and an alkaline soil using the column-leaching method. Column-leaching tests were applied to two soils (Callaway and Mount Palomar) at the depths of 0–30 and 30–60 cm.

Biochar mitigates the N2O emissions from acidic soil by increasing the nosZ and nirK gene abundance and soil pH.

Journal of Environmental Management, 2020
Nitrous oxide (N2O) is a pervasive greenhouse gas, and soil management practices greatly affect its release into the atmosphere. Soil pH management (particularly increasing the pH) using biochar can seriously affect soil N2O emissions.

In situ measurement of soil pH

Journal of Archaeological Science, 2004
Soil pH is one of the most important factors affecting the in situ preservation of archaeological artefacts of e.g. bone, shells and iron. It is therefore important to have good, reliable methods for determining the pH. However, in all methods that involve sampling of soil or water, loss of gaseous species such as carbon dioxide from the samples as ...
