*previous weeks figures in brackets

Growth is in the 50s this week due to the colder weather. This week is forecast to be much the same; rain and temperatures no more than 16°C so rotation length is extended to 22 days as we expect 50kg DM/ha of growth. CAN will be spread on most of the B paddocks and some of A as they didn’t get any in the last round. The B paddocks had lower growth rates than A&C at 44kg DM/ha; they needed Nitrogen and the colder weather slowed down the growth of clover (high % in these paddocks).

Cows will enter A1, C9 and B4 next to graze. C8 will be baled out as the cover is on the heavier side at 1400kg DM/ha but also, the paddock was grazed only to 100kg DM/ha last round and parts are still stemmy from the drought. The milk solids are remaining around the 2kg/cow so this along with the low AFC means we will keep the meal at 2.5kg. We want to start building covers by the end of this week for the Autumn Budget. The AFC must reach 1150kg DM/ha and have a cover/cow of >400kg DM by the last week of September. The low growth rates forecast will not help but hopefully the soil temperatures will increase soon.

jordanJordan Molloy – Grazing Consultant, Grasstec @Jordanmolloy22

“I teach farmers how to measure grass and the discipline needed to do weekly farm walks. I show them how to input their data onto Agrinet and how to understand the grass wedge. Each week presents a different scenario on the farm so it’s crucial that the farmer can interpret the data in order to make informed decisions. Grasstec consultants are available in Ireland and the UK.”
