Research and application of biochar in New Zealand
(ASA / CSSA / SSSA, 2016)
Readers will appreciate the comprehensive review of the latest biochar research and applications and gain critical guidance in best biochar generation and use.
Gross N transformations vary with soil moisture and time following urea deposition to a pasture soil
Ruminant urine patches in grazed grasslands significantly change the chemical and biological properties of the affected soils due to the predominance of urea within ruminant urine and the high rates deposited onto pastures. ...
Impacts of pasture species and ruminant urine on N₂O emissions and nitrogen transforming microbial communities in soil mesocosms
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-11-22)
Multispecies grasslands can alter nitrogen (N) cycling processes. A mesocosm experiment was performed comparing bare soil, soil planted with perennial ryegrass (Lolium perenne), white clover (Trifolium repens), plantain ...
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. ...
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 ...
Impact of bovine urine deposition on soil microbial activity, biomass, and community structure
Nitrogen (N) from urine excreted by grazing animals can be transformed into N compounds that have detrimental effects on the environment. These include nitrate, which can cause eutrophication of waterways, and nitrous ...
A wood based low-temperature biochar captures NH₃⁻N generated from ruminant urine-N, retaining its bioavailability
(Springer Netherlands on behalf of the Royal Netherlands Society of Agricultural Science, 2012-04)
Aims: Ammonia (NH₃) can be volatilised from the soil surface following the surface application of nitrogenous fertilisers or ruminant urine deposition. The volatilisation of NH₃ is of agronomic and environmental concern, ...
Influence of soil moisture on codenitrification fluxes from a urea-affected pasture soil
(Nature Publishing Group, 2017-05-19)
Intensively managed agricultural pastures contribute to N₂O and N₂ fluxes resulting in detrimental environmental outcomes and poor N use efficiency, respectively. Besides nitrification, nitrifier-denitrification and ...
Impact of nitrogen compounds on fungal and bacterial contributions to codenitrification in a pasture soil
(Springer Nature, 2019-09-16)
Ruminant urine patches on grazed grassland are a significant source of agricultural nitrous oxide (N₂O) emissions. Of the many biotic and abiotic N₂O production mechanisms initiated following urine-urea deposition, ...
