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 soil N cycle by altering nitrificati ...

(Lincoln College, University of Canterbury, 1986)Soil P fractionation was used to examine changes in soil inorganic and organic P under grazed irrigated pasture in a long-term field trial at Winchmore in Mid-Canterbury. The soil P fractionation scheme used involved sequential extractions of soil with O. ...

(Soil Science Society of America, 2003)Soil P composition can be conveniently determined in alkaline extracts using solution ³¹P nuclear magnetic resonance (NMR) spectroscopy, but spectral assignments are based on fragmentary literature reports of model compounds in various extraction matrices ...

(Elsevier, 2007-01)Microbial diversity in soils is considered important for maintaining sustainability of agricultural production systems. However, the links between microbial diversity and ecosystem processes are not well understood. This study was designed to gain better ...

(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2000)Phosphorus losses from agricultural soil to water bodies are mainly related to the excessive accumulation of available P in soil as a result of long-term inputs of fertilizer P. Since P is a nonrenewable resource, there is a need to develop agricultural s ...

(Soil Science Society of America, 1990)The determination of total organic phosphorus (TOP) in soils presents several methodological problems, particularly on strongly weathered and tropical soils. We reviewed the application of several methods for TOP determination to soils from different zone ...

(Springer Berlin / Heidelberg, 2007-06)Because soil biota is influenced by a number of factors, including land use and management techniques, changing management practices could have significant effects on the soil microbial properties and processes. An experiment was conducted to investigate ...

(New Zealand Plant Protection Society (Inc.), 2015)© 2015 New Zealand Plant Protection Society (Inc.). Dynamic pathogen complexes can develop under pastures, thereby substantially reducing potential productivity. Suppression of such pathogen complexes is therefore of great importance, and bioassays can qu ...

(Lincoln University & Plant and Food Research, 2010)Previous studies have reported both enhanced and reduced C and N cycling when soils of different compositions are exposed to repeated wet/dry cycles. The factors that determine the different responses are poorly understood. The objectives of this study we ...
