Grass growth rate

The universally accepted measurement of grass quantity is kilograms of dry matter per ha (KG DM/ha). Dry matter is the total yield of grass minus the water content.  Daily grass growth rates vary from 5-15 KG DM/ha in February/March to 60-100 KG DM/ha in May/June.

Sunlight, temperature and rainfall all affect grass growth. Other factors that affect grass growth, over which the farmer has control, are fertiliser application rates, length of grazing rotation and poaching damage.
