“A vigorous medic pasture of about 8 tonnes per hectare can produce up to 200 kg/ha of nitrogen in one year, equivalent to 400kg of urea.”
They are best suited to crop rotations on neutral to alkaline soils. Forage produced by annual Medics is high in protein for the grazing animal. Even the dry seed pods on the ground over summer provide a protein feed for grazing animals to maintain wool and meat growth. A vigorous Medic pasture of about 8 tonnes per hectare can produce up to 200 kg/ha of nitrogen in one year, equivalent to 400kg of urea.
This increases soil fertility, resulting in higher production of grain and fodder crops in the future. Annual Medics produce their own seed in a pod every season and if managed correctly seed pod numbers will build up in the soil. If established successfully and allowed to set adequate seed, annual Medics will regenerate year after year. This is due to their ability to produce hard seeds, a percentage of which break down each year. This mechanism also gives the annual Medics protection against drought and allows for good regeneration after 1-2 years of cropping.
