Heavy metal stress can prime for herbivore-induced plant volatile emission
(Blackwell Publishing Inc., 2012-07)
Heavy metals are important pollutants that can severely impact ecological foodwebs. In addition to direct toxic effects, these contaminants have been suggested to disrupt chemical communication channels between plants and ...
A review of the cost-effectiveness and suitability of mitigation strategies to prevent Phosphorus loss from dairy farms in New Zealand and Australia
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2012-05)
The loss of phosphorus (P) from land to water is detrimental to
surface water quality in many parts of New Zealand and Australia.
Farming, especially pasture-based dairying, can be a source of P
loss, but preventing it ...
Effects of nitrogen application rate and a nitrification inhibitor dicyandiamide on ammonia oxidizers and N₂O emissions in a grazed pasture soil
(Elsevier B.V., 2013-11-01)
Ammonia oxidizers, including ammonia oxidizing bacteria (AOB) and ammonia oxidizing archaea (AOA) are important drivers of a key step of the nitrogen cycle — nitrification, which affects the production of the potent ...
Can the application of rare earth elements improve yield and decrease the uptake of cadmium in ryegrass-dominated pastures?
(CSIRO Publishing, 2015)
© 2015 CSIRO. Rare earth elements (REEs) have been linked to increases and decreases in plant growth and the uptake of biotoxic metals such as Cadmium (Cd). We hypothesised that under the right soil and climatic conditions ...
Effect of urine, potassium and dicyandiamide application on pasture production from a free-draining Canterbury dairy pasture soil
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2014)
A cut-and-carry trial was conducted on a low quick-test potassium (QTK ≤ 4) Lismore soil during 2012-13 in Springston, Canterbury to test the responsiveness of a dairy pasture to urine, dicyandiamide (DCD) and potassium ...
The potential of using alternative pastures, forage crops and gibberellic acid to mitigate nitrous oxide emissions
(Springer Berlin Heidelberg, 2016-09)
© 2016, Springer-Verlag Berlin Heidelberg. Purpose: In grazed pastures, nitrous oxide (N₂O), a powerful greenhouse gas and an ozone depletion substance, is mostly emitted from animal excreta, particularly animal urine-N ...
Potential profit gains from improving pasture productivity on New Zealand South Island high-country farms
(New Zealand Grassland Association, 2020-09-09)
Soil acidity combined with low levels of key nutrients on New Zealand hill-country farms are limiting factors for legume establishment/growth. However, legumes are a critical component of these farms as they provide nitrogen ...
Control of gorse (Ulex europaeus) in dryland pasture converted from Pinus radiata forest
(New Zealand Plant Protection Society, 2007-09-24)
The effect of crop sequence, pasture species mixture and nitrogen fertiliser
on gorse establishment was monitored over 23 months in land converted
from pine forest to a dryland sheep pasture. There were fewer gorse plants
in ...
Response of simple grass-white clover and multi-species pastures to gibberellic acid or nitrogen fertiliser in autumn
(NZ Grassland Association, 2013)
Herbage dry matter (DM) production, botanical composition and nutritive value of pastures were measured in response to the application of 24 g/ha gibberellic acid (GA; 60 g ProGibb®/ha) and 50 kg N/ha nitrogen fertiliser ...
Yield and composition of lucerne stands in Central Otago after different winter grazing and weed control treatments
The effect of grazing date and time of spraying with a glyphosate/atrazine herbicide combination on a three year-old lucerne stand was studied on-farm in Central Otago. Total annual dry matter (DM) yield was highest in the ...
