CONSECUTIVE STEADY STATE REACTIONS OF UREA, AMMONIUM AND NITRITE NITROGEN IN SOIL
Autor: M. S. Ardakani, M. G. Volz, A. D. McLaren
Publikováno v: Canadian Journal of Soil Science. 55:83-91
Previously developed mathematical models based on first and zero order sequential transformations of urea–nitrogen to nitrate by soil urease and microorganisms, based on Michaelis–Menten-type kinetics, were examined in a laboratory soil column wi

A specific calcium requirement for potassium uptake by excised vetch roots
Autor: L. Jacobson, M. G. Volz
Publikováno v: Plant and Soil. 41:647-659
Compared to the behavior of excised barley roots, K uptake by excised roots of vetch was far more responsive to pH and required ambient Ca concentrations 100 fold higher to overcome the deleterious effect of low pH. At pH values above 7, however, the

Nitrate Dissimilation and Population Dynamics of Denitrifying Bacteria During Short Term Continuous Flow
Autor: J. L. Starr, M. G. Volz
Publikováno v: Soil Science Society of America Journal. 41:891-896
A solution containing 100 µg ml⁻¹ of NO₃⁻-N, 200 µg ml⁻¹ of glucose-C, and 0.01N CaSO₄ was supplied continuously to soil in acrylic plastic columns (6-cm inside diam × 10-cm length) for up to 96 hours while N₂ gas was passed through

Nitrogen Transformations and Microbial Population Dynamics in Soil Amended with Fermentation Residue
Autor: M. G. Volz, G. H. Heichel
Publikováno v: Journal of Environmental Quality. 8:434-439
To evaluate the fate of N in an agricultural soil treated with an N-rich industrial byproduct, fermentation residue was applied to Yalesville fine, sandy loam at a loading rate of 75 dry metric tons/ha, or 2,130 and 1,780 kg N/ha during 1975 and 1976

Nature and magnitude of calcium uptake by excised roots of Vetch and Barley
Autor: L. Jacobson, M. G. Volz
Publikováno v: Plant and Soil. 46:79-91
Generally, Ca uptakes were higher and K uptakes lower for excised vetch roots as opposed to those of barley under similar conditions. This behavior was considered to be related to root ion exchange properties and Dorman theory, since the ion exchange

The Interaction of pH and Aeration in CI Uptake by Barley Roots
Autor: M. G. Volz, B. R. Cooper, Louis Jacobson
Publikováno v: Physiologia Plantarum. 25:432-435
The uptake of Cl by excised roots of barley (Hordeum vulgare L.) from KC1 solution maintained at high pH was markedly reduced by high rates of aeration, whereas K uptake was scarcely affected. Aeration rate had relatively minor effects at low pH. The
