    Efficient use of water in agriculture
    (New Zealand Water Conference, 1970) Burton, J. R.; Heiler, Terence David
    The objects of this paper are to discuss the concept of efficiency in agricultural water use, to examine current agricultural water usage in the light of this discussion and to indicate some technological improve ments which might lead to improved efficiency in this area.

    Water resources - Problems, planning, policy
    (New Zealand Water Conference, 1970) Burton, J. R.
    It is widely accepted by New Zealanders that theirs is a wellwatered, benevolent country, having abundant supplies of rainfall and streamflow and no serious water problems. The extent to which this view is prevalent even amongst engineers and scientists working in the water resources field can be gauged from the rather surprising fact that amongst the 25 background papers to this Conference, which are supposed to provide a comprehensive statement of the water resources scene in New Zealand, there is no paper discussing the occurrence and distribution of rainfall and none which attempts a concise, overall assessment of the occurrence, distribution or extent of our surface water resources.

    Fencing: Being the proceedings of a series of talks presented at a field day held at Lincoln College in April 1980, together with some additional material
    (Lincoln N.Z. : Rural Development & Extension Centre of Lincoln College, 1980) Crabb, D. H.
    Along with most other farming costs, the relative cost of fencing is rising. Yet there is an increasing demand for more intensive and permanent fencing to allow the maximum utilisation of pasture production. Hill country is high on the list for development but is this economically viable? The answer to some of these questions is wrapped up in the technological advances made in such things as on farm log peeling and timber.preservation; permanent electric fencing; conbinations of standard wire and electric fencing; the development of battens that do not require electric insulators and in netting fencing. To display these new technologies, to pass on tips about standard fencing and to discuss other aspects became the aim of a group of interested organisations in the Canterbury area. What resulted was a field day to display and discuss wares and a series of six papers on several fencing subjects. These papers, together with some supplementary material are reproduced here. They do not represent a definitive statement on all aspects of fencing, but will give some very good hints on the topics covered.

    Field drainage guide
    (New Zealand Agricultural Engineering Institute, Lincoln College, 1978) Bidwell, Vince J.
    The N.Z.A.E.I. Field Drainage Guide is intended to be a readily available source of design information for farm advisors, contractors, farmers and others involved in agricultural drainage. The emphasis is on subsurface drainage because this is an area where the available information is often difficult to locate and confusing. The technical standards required in subsurface work are higher than for surface drainage and mistakes are not only costly but also not easily rectified. This booklet is not a comprehensive treatise on agricultural drainage and for this kind of information on New Zealand conditions the reader is referred to "The Draining of Farm Lands" by (A. W. Hudson, H. G. Hopewell, D. G. Bowler and M. W. Cross. It is presumed that the need for drainage has been established and that a suitably skilled drainage contractor is available. The information presented herein is an attempt to link these two. Drainage is by no means an exact science. Wherever possible the physical reasons for particular recommendations are given so that the designer can make a judgement on the consequences of departing from the guidelines. In some drainage situations local experience and practice may appear to conflict with methods presented in this guide. In such cases, proven successful practice must be allowed to reign with due regard for the physical reasons behind the apparent anomaly.
