Laurence Shalloo on the Impact of Nitrogen Management Strategies


Laurence Shalloo joins Emma-Louise Coffey on this week’s Dairy Edge podcast to explain the Nitrates modelling work completed by Teagasc which considered a reduction in chemical Nitrogen, consequence of non-compliance with closed dates for slurry, and a reduction in stock rate.

The work also looked at whole-farm v milking platform stocking rate and a banding system for the organic N per cow.

Laurence details the new banding system for organic Nitrogen ranks cows based on milk yield (<4,500 kg milk = 80 kg N, 4,500-6,500 kg milk = 92 kg N, >6,500 kg = 106 kg N) with the kg N expected to increase by 0.7 per annum.

This banding system is set to allow farmers to improve efficiency in the form of higher milk constituents and solids while avoiding higher banding.

Don’t forget, the Teagasc Moorepark Open Day 2021 Day is taking place on Tuesday 14th, Wednesday 15th & Thursday, 16th September 2021.

It is repeated over the three days to ensure compliance with government Covid-19 guidelines. The event consists of a planned onsite event and also a virtual event on Wednesday. If you wish to attend the event you must pre book and can do so here: www.teagasc.ie/moorepark-open-day
