Growing sales at an East Yorkshire farm machinery importer has led to the recruitment of a Business Manager.

Sancton based Manterra Ltd. has recruited Breege Kilfeather to the new position to ensure that the busy office runs smoothly and customer relationships are developed.

Breege, who has recently relocated from Buckinghamshire, where she was a housemistress at Wycombe Abbey School, will be responsible for streamlining Manterra’s data collection and management and will be the first point of contact for Manterra’s customers.

Manterra’s founder, farmer and agronomist Andrew Manfield said: “Since Manterra was...

Despite inclement weather, a Yorkshire farm machinery importer demonstrated its wide range of machinery and precision farming equipment to over 100 people at its recent demonstration days and has set a date to repeat the event next year.

Andrew Manfield and his team at Manterra Ltd conducted working demonstrations of all aspects of the Trimble and Unia ranges. Visitors were also able to preview the Baertschi OekoSem IV ROTOR-Strip-Till System that Manterra will launch at Cereals 2016 on 15th and 16th June. Two models of OekoSem were on display, one of which is already sold to Stockbridge Technology Centre as part of the research...

Research published in  the journal Agriculture, Ecosystems and Environment  has shown significant yield benefits from the injection of ammonium based fertiliser using spoke wheel injectors of the Duport type.  There was also the benefit of a reduced variation in the amount of nitrogen fertiliser taken up by the crop when comparing injection with surface application.  A summary of the article can be read by clicking here:

We're pleased to report that we have extended our range of Unia products with the launch of the MX Spreader at LAMMA Show last week.

We are the sole UK importer for Unia, the Polish agricultural machinery manufacturing giant, and the MX Spreader complements our growing range that also includes ploughs, cultivators and discs.

The MX Spreader is available in 24 and 36m spreading widths and its hopper capacity is from 850 to 3,000 litres. The hopper is also available in a full stainless steel option.

Of the launch, Manterra founder, farmer and agronomist Andrew Manfield said: “The Unia MX offers exceptional value for money...

An East Yorkshire farm machinery importer has further consolidated his partnership with Polish manufacturing giant, Unia, by launching its RCW Spreader in the UK.


Market Weighton based Manterra Ltd. is the sole UK importer for Unia Group, Central Europe’s leading manufacturer of agricultural machinery and the RCW is the latest addition to Manterra’s growing range and complements the Unia MXL fertiliser and Apollo manure spreaders that were launched earlier in the year.


The RCW Plus is a trailed fertiliser and lime spreader that features a hydraulic drive belt conveyor, border spread limiter and folding hopper...

Excellent short and fascinating history of nitrogen - not only as fertilliser.



There is a summary of this article from the Agronomy Journal at the bottom of the page below the full journal article.

Nitrogen use efficiency is one the biggest challenges facing world agriculture.  There can be no doubt that nitrogen fertiliser drives farm profitability.  But while the efficiency of uptake of nitrogen by crops is so variable there will always be a substantial environmental impact of fertiliser application.

This article from 1999 gives a good over view of the issues and possible solutions.  They are optimistic about what is possible - but there is a considerable need for education and technological progress on...

There is an interesting abstract here from the Canadian Journal of Soil Science.  Janzen, Lindwall and Roppel found significant improvements in N efficiency by using point injection methods similar to the Duport Liqiuliser spoke wheel injector.  They put most of the benefit down to the more consistent moisture conditions at the root zone where the fertiliser is placed.

A lack of uptake due to lack of moisture is,  perhaps, the biggest variable in N efficiency.  How often is fertiliser applied only for it to sit on top while the tillers die back?
