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 ...
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 ...
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 ...
Reduction of nitrogen losses by manipulating carbon inputs and pasture composition : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2020)
The nitrogen (N) cycle is very important to New Zealand agriculture, with N being a key nutrient needed for plant growth. However, there are major environmental concerns relating to the loss of N from agricultural systems. ...
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 ...
Understanding water losses from irrigated pastures on loess-derived hillslopes
(New Zealand Grassland Association, 2020-09-09)
Irrigation is likely to increase water losses from hillslopes, particularly on loess-derived soils with impeded drainage. This is important as irrigation of these soils in New Zealand is increasing. A field site was ...
Phosphorus response and efficiency of 12 novel dryland legume species on an acid high country soil
(Fertilizer and Lime Research Centre, Massey University, 2012-02)
High country soils are typically acidic and have low fertility compared with intensive high fertility low land systems. Pasture legumes commonly used in New Zealand perform poorly in these environments. The optimum soil P ...
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, ...
Potential pasture nitrogen concentrations and uptake from autumn or spring applied cow urine and DCD under field conditions
(MDPI, 2016-06)
Nitrogen (N) cycling and losses in grazed grassland are strongly driven by urine N deposition by grazing ruminants. The objective of this study was to quantify pasture N concentrations, yield and N uptake following autumn ...
