Week ending farm notes 24-12-18 

Cover has lifted this week to 2234kgDM/ha with growth of 68kgDM/ha/day occurring on the farm. This week’s growth suggests we overstate some covers last week, and therefore growth last week, (81kg/day vs 68kg/day. The average of the two at 75kg/day is still likely correct.)
