Soil fungistasis with respect to pH and profile
Canadian Journal of Microbiology, 1969Soil 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, 1996Field 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

Changes in soil pH due to the storage of soils
Soil Use and Management, 1998Abstract. 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.

Weed Science, 1975
Ten warm-season and six cool-season weed species were grown in the glasshouse on Hartsells fine sandy loam soil and Lucedale sandy loam soil at pH levels from 4.7 to 6.3. Growth of species varied widely in response to soil pH as measured by herbage yield.

The Effect of Soil pH on Nitrification in Coarse Sandy Soil
1996The 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 ...

Effect of Ph on The Bioavailability of Metals in Soils
1993Heavy metals in soils may have a toxic effect on soil biota depending on the bioavailability of these metals. The fraction of a total metal content that is available for uptake by biota depends strongly on the chemical form in which the metals are present and where they are located in the soil system.

pH changes in the rhizosphere in relation to the pH-buffering of soils
Plant and Soil, 1987pH values in the rhizosphere of peanut seedlings were measured with Sb micro electrodes in soils with a bulk pH between 3.9 and 7.7. Within 2–2.5 days the roots decreased soil pH to a minimum value which was linearly correlated with short term buffering capacity of the soils as determined by addition of HCl to soil suspensions.
