Soil pH is probably the single most informative measurement that can be made to determine soil characteristics. At a single glance, pH tells much more about a soil than merely indicating whether it is acidic or basic. For example, availability of essential nutrients and toxicity of other elements can be estimated because of their known relationship with pH. The term pH was "invented" by the Swedish scientist Sorensen (1909) in order to obtain more convenient numbers and the idea quickly caught… 
Salt Concentration and Measurement of Soil pH
The measured value of soil pH depends in part on the laboratory procedures used, such as the soil–solution ratio and soil solution electrolyte composition. One of the most significant factors
Soil calcium and pH monitoring sensor system.
The sensorial system based on temperature, moisture, and all solid-state ion-selective potentiometric sensors in a complex, discontinued, and heterogeneous matrix, such as soil, proved to be a useful task for agrochemical field applications.
Reconstructing pH of Paleosols Using Geochemical Proxies
Soil pH is essential for understanding weathering, nutrient availability, and biological-edaphic relationships. However, standard pH measurement on soils requires friable material, thereby excluding
Changes in Soil pH and Exchangeable Acidity of Selected Parent Materials as Influenced by Amendments in South East of Nigeria
Soil chemical degradation caused by acidity is a serious constraint to food production in most parts of the Tropics. It was in the bid to proffer solution to this that the present study was
The Comparison of Olsen, DMT-HFO and DGT Methods for Assessment of Plant Available Phosphorus in Soils
Phosphorus (P) is one of the most important limiting nutrients for crop production in the world soils. Excessive and deficiencies of P in calcareous soils has been reported. Several methods can be
Predicting Molybdenum Adsorption by Soils Using Soil Chemical Parameters in the Constant Capacitance
cated that Mo adsorption on calcium carbonate was low, reanalysis of their data indicated that adsorption on The constant capacitance model, a chemical surface complexation this CaCO3 at pH 7.1 was
A Modified DMT-HFO Technique for Investigating the Kinetics of Phosphorus Desorption from Calcareous Soils and its Relationship with Maize Growth
ABSTRACT In this research, phosphorus (P) desorption was investigated using DMT-HFO as an “infinite” sink for 10 calcareous soils over a period of 1–35 days and the kinetic data was related to soil


Measurement of soil pH
A number of experimental results are presented which show the variation of the pH values of several soils when samples of each are shaken with CaCl/sub 2/ solutions of different concentrations. These
A Comparison of Methods for the Determination of Soil Reaction1
Summary and ConclusionsA comparison of methods for determining soil reaction and lime requirements of soils was made, using 150 soils that were representative of the three soil provinces of Virginia.
In recent years the lime potential, pH-p(Ca + Mg), has received considerable attention (3, 6, 8, 9, 10). It was proposed by Schofield (5) as a measure more fundamental of the base status of a soil
Hydrogen and Calcium Ion Ratios in Dilute Equilibrium Solutions as Related to Cation Saturation 1
Soil samples were collected from field experiments so as to obtain a range in (Ca + Mg) saturation and pH for each soil type. The effects of equilibrating media were studied by comparing water and
Buffer Curves of Acid Clays as Affected by the Presence of Ferric Iron and Aluminum 1
Buffer curves of Al- or Fe-montmorillonites and hectorite in 1.0N KCl had appreciably smaller slopes between pH 5 and 8.5 than did curves for corresponding H-clays. Aluminum or ferric hydrous
The Fabrication of H+-Selective Liquid-Membrane Micro-electrodes for Use in Plant Cells
Testing the electrodes on 11 different cell types of Riccia fluitans, the internal pH is found slightly alkaline in ten cases, and it is concluded that the pH-electrode measures in the cytosol.
The Cause of the Suspension Effect in Resin‐water Systems
Osmotic pressure and freezing point determinations provided confirmatory evidence that the activity of ions was virtually identical in slurry and dialyzate even though the suspension effect was exceptionally large.
