Recently the Fertilizer Association of Ireland launched the Nutrient Calculator Wheel in conjunction 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 off-take 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 calculator is available to advisers, consultants and industry representatives.
The calculator is also available to farmers on request at participating agri-business stores around the country.
