The pH optimum of soil exoenzymes adapt to long term changes in soil pH [PDF]

open access: yesSoil Biology and Biochemistry, 2019
Soil exoenzymes released by microorganisms break down organic matter and are crucial in regulating C, N and P cycling. Soil pH is known to influence enzyme activity, and is also a strong driver of microbial community composition; but little is known about how alterations in soil pH affect enzymatic activity and how this is mediated by microbial ...

pH of Very Acid Soils [PDF]

open access: yesNature, 1971
THE purpose of this note is to call attention to the fact that usual methods of measuring soil pH1 seriously underestimate the pH of very acid soils, such as those of coal mine spoils2, cat clays3 and solfataras4, in which acidity is due to the presence of free sulphuric acid. Standard methods for measuring soil pH involve making a slurry of soil with (

Soil pH Mapping with an On-The-Go Sensor [PDF]

open access: yesSensors, 2011
Soil pH is a key parameter for crop productivity, therefore, its spatial variation should be adequately addressed to improve precision management decisions. Recently, the Veris pH ManagerTM, a sensor for high-resolution mapping of soil pH at the field scale, has been made commercially available in the US.

Determination and Correlation of pH and Electrical Conductivity of Assosa Agricultural Research Center Sites Soil

open access: yes, 2022
Soil pH has high impact on soil biogeochemical processes in the natural environment. Soil pH is thus referred to as the "master soil variable" because it influences a plethora of soil biological, chemical, and physical properties as well as processes ...

Bacterial pH-optima for growth track soil pH, but are higher than expected at low pH

open access: yes, 2011
One of the most influential factors determining the growth and composition of soil bacterial communities is pH. However, soil pH is often correlated with many other factors, including nutrient availability and plant community, and causality among factors
