The current grassland situation on farm and a look at future growth rate predictions

Micheal O’Leary from PastureBase Ireland and Grassland Researcher Elodie Ruelle join Emma-Louise Coffey to discuss the current grassland situation on farm and look at future growth rate predictions.Micheal starts by explaining the current grassland situation, including high growth rates of on average 77 kg DM/ha exceeding farm demand of 60 kg DM/ha. The additional feed is driving farm cover/cow to over 200 kg DM/ha, compared with target of 160-180 kg DM/ha.  The considerable amount of rain that has fallen in recent days combined with predictions of continued high growth re-assures Micheal that farmers can be proactive in removing heavy covers to prevent a reduction in milk production.Micheal's tips are:1.       Graze maximum cover of 1,500 kg DM/ha2.       Measure twice weekly during peak grass growth and remove heavy paddocks (Spread soiled water or compound fertiliser after spreading)3.       Target farm cover of 160-180 kg DM/ha and an 18-21 day rotation Elodie Ruelle explains the model that she has created for grass growth which accounts for weather conditions (past and predicted), soil type, Nitrogen levels and Biomass. The grass growth predictions are made across 40 farms in Ireland. Accuracy is high as the farms are measuring at least weekly and recording Nitrogen usage on a weekly basis. Elodie's predications appear in the weekly Grass 10 bulletin. Finally, Micheal reflects on Grassland for 2019 reporting the excellent year to date including at least 1 additional grazing across farms on PastureBase Ireland this year compared with 2018 with production up 1 tonne/ha. For more information:https://www.teagasc.ie/crops/grassland/grass10/grass10-newsletter/
