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 ...
Irrigation effects on soil organic carbon under a ryegrass-white clover pasture on a Lismore stony silt loam soil : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2020)
Long-term summer irrigation of temperate managed pastures has been reported to either increase or decrease soil organic carbon (SOC) stocks when compared with dryland systems. Understanding the short-term effects of ...
Quantifying contaminant losses to water from pastoral land uses in New Zealand III. What could be achieved by 2035?
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-11-11)
To meet the water quality outcomes sought by catchment communities and regulators, the losses of nitrogen (N), phosphorus (P) and sediment from dairy and sheep/beef farms must be reduced across many catchments. We conducted ...
Increased soil nitrogen supply enhances root-derived available soil carbon leading to reduced potential nitrification activity
Nitrogen (N) immobilisation by heterotrophic microorganisms is critical for reducing N losses from soils and ensuring a long-term supply of N to plants in grassland ecosystems. The supply of carbon (C) available to soil ...
The influence of rock fragments on field capacity water content in stony soils from hard sandstone alluvium
Worldwide, rock fragments (RFs) are generally considered inert with respect to bulk soil hydraulic properties, such that all soil water retention properties predicted by national pedotransfer functions (such as S-map) are ...
