Grass growth has further dropped to 26kg this week due to high temperatures and soil moisture deficit. Saturday night we got rain; only 21mm in total this week. Hopefully, this will improve this coming week’s growth rates. The AFC has dropped to 460kg so we will keep the baled silage in the diet in order to try get back on track on the Autumn Budget. The A paddocks have AFC 294kg and growth of 21kg, B paddocks have AFC of 424kg and growth of 20kg and C paddocks have AFC of 704kg and 44kg growth. 3.37ha will be coming into the milking platform in the next 4 weeks so this has been added in the budget.
The cows are grazing low covers in A (500-600kg) with silage shaken out on top of the grass. The B paddocks are low enough too, around 800kg with silage on top as well. The C paddocks are still growing well as they have heavier soil and are in less of a moisture deficit. The four paddocks out for reseeding will get 2tonnes of limes/acre today. Some B and A paddocks will get CAN this week; A still looks hungry but this could be due to the lack of moisture present in order for the grass to take up the N. Rotation length has been extended to 29 days; it needs to be 30 by the end of the month and 35 days by mid-September.
Jordan 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.”
