New 'Nutrient Wheel' Calculator will help Farmers and Advisers with Grassland and Crop Nutrient Advice - DAFM
14 August 2012
A new ‘Nutrient Calculator Wheel’ has been
launched by the Minister for Agriculture, Food and the Marine,
Simon Coveney TD. The nutrient wheel was produced by The
Fertilizer Association of Ireland, in association with Teagasc,
and K+S UK & Eire Ltd.
The nutrient wheel is a field ready reckoner for estimating the
phosphorus and potassium offtakes from grassland and tillage
crops in Ireland. It consists of an easy-to-use wheel that shows
the estimated offtake of phosphorus and potassium based on
simple input values of stocking rate, concentrate feed usage and
crop yield. It also includes useful field notes on soil test
results and fertility levels, organic manures, lime, sulphur and
magnesium. The Minister for Agriculture, Food and the Marine,
Simon Coveney, TD said that “this is a great initiative by all
parties concerned and will play an important role in ensuring
that fertiliser inputs are used efficiently in a cost effective
and environmentally friendly manner.” Minister Coveney also
commended the Fertilizer Association of Ireland, Teagasc and K +
S UK & Eire Ltd for the proactive approach they had taken in
producing the nutrient wheel.
Stan Lalor, President of the Fertilizer Association of Ireland
said that the Association is delighted to be leading this
project to help make information more accessible and available
to advisors, consultants, industry representatives and farmers.
Fertilizers are an important input for agricultural production,
and it is essential to use them efficiently to maximise returns
and to protect the environment. The nutrient wheel will provide
an easy way of calculating phosphorus and potassium requirements
and will help to optimise fertilizer inputs.
Mark Plunkett, soil and crop nutrition specialist with Teagasc,
said: “the nutrient offtake calculations used in the calculator
are in line with Teagasc advice. Crop yields and quality will be
reduced where soil fertility is allowed to decrease to
sub-optimal levels over time. Soil fertility levels have been
shown to be declining in recent years from results of soil
samples being analysed through Teagasc. Replacing nutrients
removed in crops is essential to maintaining and managing soil
fertility. This easy-to-use nutrient wheel will provide quick
and simple nutrient recommendations and will be useful for
anybody giving advice on nutrient inputs for grassland and crop
production.”
Jerry McHoul, K+S UK & Eire Ltd., said that a similar calculator
wheel for arable crops had been launched in 2011 in the UK and
has proven highly popular and successful. K+S UK & Eire are
delighted to see the concept adapted to grassland and made
compatible with nutrient advice for Irish agriculture.
The calculator is available to advisors, consultants and
industry representatives. The calculator is also available to
farmers on request at participating agri-business stores around
the country.

Secretary of the Fertiliser Association of Ireland.
