Grass growth has increased by 2.5tons /ha on average over the last three years on the 11 Teagasc/Glanbia monitor farms.
Overall stocking rate also increased also going from 2.1lu/ha to 3.01lu/ha. The milking platform stocking rate has increased from 2.1 lu/ha to 3.01lu/ha. In 2014, on average the 11 monitor farmers were milking 100 cows each and now they are milking 161 cows on average.

Soil analysis summary

- 47% were low in K
- 47% were low in P
A soil fertility plan was created and implemented on all farms. The farms have been retested this winter and all the soils tests will be back shortly. From the results that that have come back already there is a massive improvement, especially in Ph.
Silage fields have been slower to rise even after a high level of slurry and 0/7/30 but this is expected following two to three cuts of silage.
On average 40% of the land was reseeded over the last three years.
Grassland management has also improved over the period. On average the farms were walked 35 times per year and measurements recorded. Decision making after the grass walks improved as the farmers became more confident with the figures. During periods of high growth the farms were walked twice per week.
