Dry matter production and water use of dryland cocksfoot/lupin and lucerne pastures in the third year after establishment
(Lincoln University, 2017-11-14)
Cocksfoot (Dactylis glomerata) is a preferred grass option for dryland pastures on high country farms in the South Island of New Zealand. However, increasing the productivity of cocksfoot based pastures with legumes is ...
Livestock and pasture production from dryland lucerne and two lucerne/grass mixtures over four years in Canterbury
(Lincoln University, 2017)
The productivity of a lucerne monoculture, lucerne/brome and lucerne/cocksfoot binary mixtures grown on shallow soils at Ashley Dene, Canterbury, were compared under grazing over four years. Pastures were grazed with ...
Phosphorus legacy: role of long-term soil phosphorus accumulation in the sustainable management of intensive agroecosystems
(Lincoln University, 2017-08-02)
Phosphorus (P) is an essential nutrient for all organisms. Phosphate rock is primarily utilised for the manufacture of P fertilisers, and is a finite resource. Most agricultural lands worldwide present low levels of available ...
The effect of pre-mowing pasture on milk, pasture, and nitrogen partitioning of dairy cows in the autumn
(Lincoln University, 2014)
The effect of pre mowing on pastures of high or low mass was investigated to determine whether herbage quality, intake, milk yield and nitrogen use efficiency (NUE) of dairy cows could be increased. The experiment was ...
An investigation of the incorporation of a standoff facility with the grazing of fodder beet in a Canterbury dairy wintering system
(Lincoln University, 2014)
Dairy farmers are under scrutiny for the negative effect their farming operations have on the environment, particularly in regard to nitrate leaching. The National Policy Statement for Freshwater has directed regional ...
Catch crops to mitigate N loss after winter forage grazing: From plot to paddock
(Fertilizer and Lime Research Centre, Massey University, 2019)
Recent research has shown sowing a catch crop can reduce nitrate leaching after simulated winter forage grazing. However, most of this research has been reported from lysimeter and small plot trials where the pragmatic ...
Flowability testing for aerial lime
(Fertilizer and Lime Research Centre, Massey University, 2019)
The Civil Aviation Authority (CAA) requires that topdressing aircraft are capable of jettisoning 80% of the aeroplane’s maximum hopper load within five seconds of the pilot initiating the jettison action. For granulated ...
Effective bout widths for uniform spread of lime from ground spreaders
(Fertilizer and Lime Research Centre, 2019)
There is a strong correlation between crop yields and evenness of application of lime. Lime is the most widely used fertiliser/soil conditioner product in New Zealand, but it is not very mobile in the soil, so it is important ...
Evaluation of perennial lupin/cocksfoot pasture relative to lucerne pasture under summer dry conditions
(New Zealand Grassland Association, 2016)
The productivity of a perennial lupin/cocksfoot mix was compared to that of lucerne in summer dry conditions at Lincoln University, Canterbury, New Zealand. The pastures were planted in December 2013 and rotationally grazed ...
Photogrammetry for assessment of pasture biomass
(New Zealand Grassland Association, 2019-11-04)
New tools are required to provide estimates of pasture biomass as current methods are time consuming and labour intensive. This proof-of-concept study tested the suitability of photogrammetry to estimate pasture height in ...
