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 ...
Potential use of biosolids to reforest degraded areas with New Zealand native vegetation
(Crop Science Society of America with Soil Science Society of America and American Society of Agronomy, 2017-06-30)
Biosolids could potentially be used for reforestation of degraded soils in New Zealand with native vegetation. Many native plant species of New Zealand thrive in low-fertility soils, and there is scant knowledge about their ...
