Trace metal mobilization by organic soil amendments: Insights gained from analyses of solid and solution phase complexation of cadmium, nickel and zinc
The accumulation of Cd in soils worldwide has increased the demand for methods to reduce the metal's plant bioavailability. Organic matter rich soil amendments have been shown to be effective in achieving this. However, ...
A mesocosm study of oxygen and trace metal dynamics in sediment microniches of reactive organic material
(Nature Publishing Group, 2017-09-12)
Deposition of particulate organic matter (POM) induces diagenetic hot spots at the sediment-water interface (SWI). Here we explore the effects of intensive POM degradation for metal mobilization at the SWI. By using a ...
Effects of lime and organic amendments derived from varied source materials on cadmium uptake by potato
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2017-07)
Repeated applications of Cd-rich phosphate fertilizers have resulted in elevated concentrations of this toxic element in some New Zealand soils. Exceedance of the food safety standard for Cd (0.1 mg kg⁻¹ fresh weight) has ...
Response of a pioneering species (Leptospermum scoparium J.R.Forst. & G.Forst.) to heterogeneity in a low-fertility soil
(Frontiers Media S.A., 2019-02-06)
Root foraging may increase plant nutrient acquisition at the cost of reducing the total volume of soil explored, thereby reducing the chance of the roots encountering additional patches. Patches in soil seldom contain just ...
