Irrigation effects on soil organic carbon under a ryegrass-white clover pasture on a Lismore stony silt loam soil : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2020)
Long-term summer irrigation of temperate managed pastures has been reported to either increase or decrease soil organic carbon (SOC) stocks when compared with dryland systems. Understanding the short-term effects of ...
Assessment of the application of gibberellins to increase productivity and reduce nitrous oxide emissions in grazed grassland
(Elsevier, 2015-09-01)
© 2015 Elsevier B.V. Emissions of nitrous oxide from grassland systems are attributable largely to the use of nitrogen fertilisers and the excreta deposited by grazing animals. There is increasing interest in using ...
Soil biodiversity and biogeochemical function in managed ecosystems
(CSIRO, 2020-01)
A complex combination of environmental, biological, chemical, and physical properties and processes determine soil biodiversity and its relationship to biogeochemical functions and ecosystem services. Vegetation, land-use, ...
Increased soil nitrogen supply enhances root-derived available soil carbon leading to reduced potential nitrification activity
(Elsevier, 2021-03)
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 ...
Regular estimates of herbage mass can improve profitability of pasture-based dairy systems
(CSIRO Publishing, 2018-01-05)
Paddock selection is an important component of grazing management and is based on either an estimate of herbage mass, or the interval since last grazing for each paddock. Obtaining estimates of herbage mass to guide grazing ...
Permanent wilting point plays an important role in simulating winter wheat growth under water deficit conditions
(Elsevier B.V., 2020-02-28)
Soil parameters related to soil water holding capacity could play an important role in simulating winter wheat growth under severe soil water stress, which could heavily influence the simulated soil water contents, and ...
Changes in soil phosphorus availability and potential phosphorus loss following cessation of phosphorus fertiliser inputs
(CSIRO Publishing, 2013-09-23)
Long-term application of phosphorus (P) fertilisers to agricultural soils can lead to in the accumulation of P in soil. Determining the rate of decline in soil P following the cessation of P fertiliser inputs is critical ...
Challenges and opportunities in harnessing soil disease suppressiveness for sustainable pasture production
(Elsevier, 2016-04)
Grasslands are an important source of biodiversity, providing a range of essential ecosystem services such as ensuring water quality and soil carbon storage. An increasing proportion of grasslands are used for pastoral ...
Biochar adsorbed ammonia is bioavailable
(Springer Netherlands, under the auspices of the Royal Netherlands Society of Agricultural Science, 2012-01)
Biochar is produced as a by-product of the low temperature pyrolysis of biomass during bioenergy extraction and its incorporation into soil is of global interest as a potential carbon sequestration tool. Biochar influences ...
Biochar and fertiliser applications influence phosphorus fractionation and wheat yield
(Springer Berlin Heidelberg, 2014-01)
The use of biochar in agriculture to achieve the dual benefits of improving soil quality whilst sequestering carbon (C) has received much attention. However, in low-intensity broadacre agricultural systems where yield is ...
