An evaluation of recent advances in the use of anhydrous and aqueous ammonia overseas and their application in New Zealand horticulture
(Lincoln College, University of Canterbury, 1968)
The object of this study is to evaluate recent advances in the use of anhydrous and aqua ammonia as nitrogenous fertilisers, with emphasis on the prospects and needs there are for their usage in New Zealand. There is at ...
Fertilizers in New Zealand, 1867-1929
(Canterbury Agricultural College, University of New Zealand, 1929)
In 1869, New Zealand use 216 tons of imported fertilizers in addition to a very small amount of local bonedust. Sixty years later, the imports amounted to 324,145 tons, while local production was in the neighbourhood of ...
An economic evaluation of high nitrogen fertiliser rates at Limestone Downs
(Lincoln University. Faculty of Commerce. Kellogg Rural Leaders Programme., 2005)
Increased nitrogen application has potential to achieve "step change" in
forage production and productivity of hill country properties. This paper
reports the results of a financial evaluation of high rates of nitrogen ...
Budgeting further development on intensive sheep-farms in Southland
(Lincoln College. Agricultural Economics Research Unit., 1967)
This publication is the second report arising out
of the Unit's research programme on fertiliser economics
in New Zealand farming. The first report analysed actual
farm output at the intensive margin in Southland; ...
Fertiliser and production on a sample of intensive sheep farms in Southland 1953-64
(Lincoln College. Agricultural Economics Research Unit., 1967)
In this publication we set out the results of a comparative
study of intensive lamb production in Southland. Farm records for a
ten year period are analysed in terms of fertiliser application,
stocking rates and net ...
The assessment and potential for mitigation of phosphorus losses from Organic soils under intensive dairying
(Lincoln University, 2016)
The development of marginal land under Organic soils for intensive agricultural use is commonplace around the globe, being driven by population growth and the limited availability of alternative, highly productive soils. ...
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 ...
Discharge coefficients of flat-fan nozzles
(American Society of Agricultural and Biological Engineers, 2017)
The discharge coefficient (Cd) is a measure of how much of the pressure energy of a nozzle is converted into kinetic energy. With the discharge coefficient known, the exit velocity of the liquid sheet from the nozzle can ...
Export of nitrogen and phosphorus from artificially drained dairy pastures in the Hauraki Plains
(FLRC, 2017-02)
This work forms part of the MBIE-funded Transfer Pathways Programme, which targets quantification of the pathway-specific transfers of nitrogen (N) and phosphorus (P) from the land to receiving waters, taking lag times and ...
