Using nitrogen fertiliser to decrease phosphorus loss from high phosphorus soils
Decline in soil phosphorus (P) concentrations is slow, and environmentally significant concentrations of P can be lost to water long after fertiliser application is decreased. One potential method to accelerate the decline ...
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 ...
Variable effect of Trichoderma bio-inoculants on ectomycorrhizal colonisation of Pinus radiata seedlings
(Lincoln University, 2006-07)
The effect of Trichoderma inoculation on ECM growth and colonisation was investigated in both a pot experiment and in a dual plate bioassay.
Influence of organic and mineral amendments on microbial soil properties and processes
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 ...
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 ...
Small-scale spatial variability of selected soil biological properties
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 ...
Impact of biochar coated with magnesium (hydr)oxide on phosphorus leaching from organic and mineral soils
(Springer Verlag, 2018-11-30)
Purpose: Recent research suggests that Swedish organic arable soils have been under-recognized as a potential source of phosphorus (P) loading to water bodies. The aim of this study was to compare P losses through leaching ...
Effect of land use and soil organic matter quality on the structure and function of microbial communities in pastoral soils: Implications for disease suppression
(Public Library of Science, 2018-05-07)
Cropping soils vary in extent of natural suppression of soil-borne plant diseases. However, it is unknown whether similar variation occurs across pastoral agricultural systems. We examined soil microbial community properties ...
Phosphorus leaching from an organic and a mineral arable soil in a rainfall simulation study
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2018-05-03)
Phosphorus derived from agricultural systems has been found to cause eutrophication of surface waters. To combat this, the specific location of soil profile P release is necessary for development of effective mitigation ...
A review of biochar and soil nitrogen dynamics
Interest in biochar stems from its potential agronomic benefits and carbon sequestration ability. Biochar application alters soil nitrogen (N) dynamics. This review establishes emerging trends and gaps in biochar-N research. ...
