Another field out of grazing and into silage to keep on top of grass covers

Do you take out for silage if the cover is over 2700kg/DM

More to do with identifying the build up of surplus within the wedge, fields that have the fertility to withstand all the P and K that goes with silage and time of year. Wouldn’t be keen on silaging covers less than 4500kg due to costs but they would be removed from grazing platform at a lower cover.
