Abstract

The rhizobox system offers quantitative information concerning the pH changes and the range of the rhizosphere. Changes in pH values around the roots (barley and soybean) were investigated using a rhizobox. The results indicated that the pH values increased near the roots in soils with a low pH of the bulk soil (about 5). Changes of pH were as much as 2 units, compared to the bulk soil. Conversely, the rhizosphere pH decreased by about 2 units in soils with a bulk soil pH of 7. A slight decrease in the rhizosphere pH was observed in soils with a bulk soil pH of 8.4. The ability of soybean roots to influence the pH was larger than that of barley. No effect of N -serve on the pH of the rhizosphere and bulk soil was observed when ammonium sulphate was applied. These results suggest that the extent to which the rhizosphere pH can differ from that of the bulk soil depends more on the plant species and initial bulk soil pH than upon N-fertilizer source or N-level.

  • Barley and soybean grown on clay loam soils showed alkalization in the rhizosphere at an initially low pH (4.8), and acidification at high initial pH values (7.1).

    “Other examples are barley and soybean grown on clay loam soils, for which alkalization occurred in the rhizosphere at an initially low pH (4.8), and acidification at high initial pH values (7.1) (Youssef and Chino, 1989).”

    From Potentials of Miscanthus x giganteus for phytostabilization of trace element-contaminated soils: Ex situ experiment (2021) · cites this paper as Youssef and Chino, 1989

    The Results and Discussion report rhizosphere alkalization for barley in low-pH clay loam and acidification for both barley and soybean in clay loam at about pH 7. The Rhizobox system section describes soybean as being planted in the pH-raised experiment, not the low-pH experiment, so the claim extends the low-pH result to soybean. The soil-properties table also lists 4.8 as a KCl measurement, rather than the soil’s initial water pH. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
