Small-scale spatial variability of selected soil biological properties
(Elsevier, 2004-04)
A strategy for sampling soil from intact monolith lysimeters was established based on measurements of spatial heterogeneity within the lysimeter area. This was part of an ongoing study to determine relationships between ...
Influence of organic and mineral amendments on microbial soil properties and processes
(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 ...
Processes governing phosphorus availability in temperate soils
(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 ...
Relationship between microbial community properties and nitrogen mineralisation in soils after amendment with two forms of nitrogen
(2006-08)
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 ...
Phosphorus-31 nuclear magnetic resonance spectral assignments of phosphorus compounds in soil NaOH–EDTA extracts
(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 ...
Increasing phosphate rock availability using a lupin green manure crop
(Lincoln University, 2004)
Legumes have been shown to increase the dissolution and utilisation of phosphate rock (PR) phosphorus (P) compared with non-legumes because of their acidifying effect on the rhizosphere. A promising agronomic approach for ...
Effects of past and current crop management on soil microbial biomass and activity
(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 ...
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 ...
Analysis of potentially mobile phosphorus in arable soils using solid state nuclear magnetic resonance
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2002)
In many intensive agroecosystems continued inputs of phosphorus (P) over many years can significantly increase soil P concentrations and the risk of P loss to surface waters. For this study we used solid-state ³¹P nuclear ...
Critical evaluation of methods for determining total organic phosphorus in tropical soils
(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 ...
