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 ...
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
(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 ...
Likely controls on dissolved reactive phosphorus concentrations in baseflow of an agricultural stream
(Springer, 2020-05-06)
Purpose: High baseflow phosphorus (P) concentrations increase the likelihood of periphyton blooms. Several physical and chemical factors can control baseflow P concentrations such as hydraulic exchange with groundwater, ...
Soil gas diffusivity controls N₂O and N₂ emissions and their ratio
(Soil Science Society of America, 2016-05-06)
Knowledge of soil biological and physical interactions with respect to N₂O and N₂ fluxes is essential to ensure that agricultural land management is environmentally and economically sustainable. This study determined how ...
Dissolved organic nitrogen : an overlooked pathway of nitrogen loss from agricultural systems?
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2009)
Conventional wisdom postulates that leaching losses of N from agriculture systems are dominated by NO₃⁻. Although the export of dissolved organic nitrogen (DON) into the
groundwater has been recognized for more than 100 ...
Dynamics of nitrous oxide in groundwater at the aquatic-terrestrial interface
(Blackwell Publishing, 2007-04-10)
Few data are available to validate the Intergovernmental Panel on Climate Change's emission factors for indirect emissions of nitrous oxide (N₂O). In particular the N₂O emissions resulting from nitrogen leaching and the ...
Nitrous oxide fluxes, soil oxygen, and denitrification potential of urine- and non-urine-treated soil under different irrigation frequencies
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2016-07)
© American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America. 5585 Guilford Rd., Madison, WI 53711 USA. All rights reserved. Despite increased use of irrigation to improve forage ...
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 ...
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 ...
