Unweathered wood biochar impact on nitrous oxide emissions from a bovine-urine-amended pasture soil
(Soil Science Society of America, 2010)
Low-temperature pyrolysis of biomass produces a product known as biochar. The incorporation of this material into the soil has been advocated as a C sequestration method. Biochar also has the potential to influence the ...
Lime and soil moisture effects on nitrous oxide emissions from a urine patch
(Soil Science Society of America, 2004)
Liming has been mooted as a mitigation option for lowering soil N₂O emissions. This study investigated the effect of soil pH and soil water content on N₂O and N₂ emissions following the addition of synthetic urine (500 kg ...
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 ...
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 ...
Soil microbial community restructuring and functional changes in ancient kauri (Agathis australis) forests impacted by the invasive pathogen Phytophthora agathidicida
New Zealand's culturally iconic, ancient kauri (Agathis australis) forests are threatened with extinction as a result of dieback caused by an invasive and highly virulent soil-borne pathogen (Phytophthora agathidicida). ...
