Fertiliser-coating technology to improve the efficiency of copper uptake in pastures
(Fertilizer and Lime Research Centre, Massey University, 2018)
Current practice for trace element (TE) application is to admix granular trace elements in with macro-elemental fertilisers. Although the correct rate of trace elements per hectare can be applied, the distribution of the ...
Effect of urine, potassium and dicyandiamide (DCD) application on pasture production from a free-draining Canterbury dairy pasture soil
(Fertiliser and Lime Research Centre, 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 ...
Assessing biomass yield of kale (Brassica oleracea var. acephala L.) fields using multi-spectral aerial photography
(Fertilizer and Lime Research Centre, 2015-02)
Aerial images were taken in June 2014 with a multispectral VIS/NIR camera of the canopy from 14 kale (Brassica oleracea var. acephala L.) fields in Canterbury, New Zealand before this forage was grazed by cows. Images ...
Factors influencing fertiliser and lime decisions on South Island high- and hill-country farms
(New Zealand Grassland Association, 2020-09-09)
Highlights • Fertiliser and lime decisions by high-and hill-country farmers directly impact on their farm performance, but the factors influencing these decisions are not well understood. • Factors influencing South Island ...
Nitrosospira cluster 8a plays a predominant role in the nitrification process of a subtropical Ultisol under long-term inorganic and organic fertilization
(American Society for Microbiology, 2018-09)
Long-term effects of inorganic and organic fertilization on nitrification activity (NA) and the abundances and community structures of ammoniaoxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) were investigated ...
Our nitrogen 'footprint': the need for increased crop nitrogen use efficiency
(John Wiley & Sons, Inc. on behalf of the Association of Applied Biologists, 2013-09)
Nitrogen (N) is an essential element for the growth and development of all living organisms, as it is a constituent of DNA, RNA, ATP and protein. In plants, N is also an essential component of other key compounds including ...
Effects of N fertilisation, leaf appearance and time of day on N fractionation and chemical composition of Lolium perenne cultivars in spring
(Elsevier B.V., 2012-05-11)
New Zealand dairy systems are based on Lolium perenne pastures with low nitrogen use efficiency (NUE) and high urinary N losses. Modelling attempts to provide solutions to improve NUE are limited due to lack of data on ...
Nutrient recycling using biowastes from diverse sources
(Lincoln University, 2018)
Phosphorus is a limiting nutrient in crop growth and thus widely used as an agricultural fertiliser. It cannot be substituted by another element, nor newly synthesized. Hence, global food production is ultimately dependent ...
