Mapping Soil pH

Soil Science Society of America Journal, 2005
The theoretical profitability of variable rate (VR) lime management has driven adoption of intensive soil sampling strategies used with complex statistical techniques without demonstration of approach efficacy. Our objective was to compare the accuracy of spatially continuous pH and lime requirement (LR) maps derived from ...

Adopting a Robotic pH Instrument for Soil and Soil-Buffer pH Measurements in a Soil Test Laboratory

Communications in Soil Science and Plant Analysis, 2011
Optimum software settings were evaluated to minimize time of analysis without sacrificing data quality on an AS-3010D LabFit robotic instrument. There was little to no difference between soil and soil-buffer pH values measured via manual methods and LabFit analysis with four software settings. A setting for routine laboratory analysis was determined by

pH Tests on Soils

Proceedings of the Prehistoric Society, 1987
pH tests were carried out on eight soil samples taken from the site at the time of excavation. These were prepared and processed according to Black 1965, 922-923. Locations of the samples and the results showing the soils to be acidic are given below. All the samples were taken from the medium brown sandy loam (fig. 4).

Interrelations between soil pH measurements in various electrolytes and soil solution pH in acidic soils

Australian Journal of Soil Research, 1991
Ninety soil samples (81 surface, 9 subsurface) were collected from eastern Queensland and soil pH (1:5 soi1:solution) was measured in each of deionized water (pH,), 0.01 M CaCl2, 0-002 M CaCl2 and 1 M KCl. Soil solution was extracted from each soil after incubation for 4 days at the 10 kPa matric suction moisture content, and pH (pHss) and electrical ...

Effect of pH on the sorption of uranium in soils

Journal of Environmental Radioactivity, 2001
This work was undertaken to study the influence of soil type and chemical composition on uranium sorption ratios (SR in 1 kg-1) in order to reduce the uncertainty associated with this parameter in risk assessment models. Thirteen soil samples were collected from three different locations in France under different geological conditions.

Soil fungistasis with respect to pH and profile

Canadian Journal of Microbiology, 1969
Soil fungistatic activity was determined in different soils using the sterile cellophane–agar diffusion method. Comparing 35 soil samples from eight profiles, the inhibitory effect on Trichoderma koningi was found to increase with increasing soil pH irrespective of the depth at which the soil samples were taken.The fungistatic principle of seven soils

Soil pH Effect on Imazaquin Persistence in Soil

Weed Technology, 1996
Field studies were conducted to determine the effect of soil pH ranging from 5.1 to 7.1 on imazaquin persistence on a Grundy silty clay loam (2.8% OM). Imazaquin residues were equivalent at pH 5.5 or higher but persisted longer at pH 5.1. Corn shoot growth was not different at any soil pH. Corn grain yields in 1993 were lower in imazaquin-treated plots

The Effect of Soil pH on Nitrification in Coarse Sandy Soil

1996
The effect of soil pH on the nitrification at low temperatures was studied in a coarse sandy soil. Field incubations were carried out during two winter periods in a field trial with soil pH-values from 4.2 to 6.2. In the laboratory the effect of soil pH on N-mineralization and nitrification was measured after application of liquid pig manure and ...

Changes in soil pH due to the storage of soils

Soil Use and Management, 1998
Abstract. The pH of soil samples was remeasured after storage for 20 years in the laboratory. The pH decreases were minor in acid to neutral soils (‐0.3), but greater in alkaline soils (‐0.63). The pH differences were statistically significant only for alkaline soils.
