New Leys is grassland that is sown, grazed and maintained for a few
years and is then dug up. This increases the potential growth of
grass in an area.
Permanent weeds are simpler to eradicate and the
newest high-yielding grass seeds can be sown. New leys can be
planted continuously on the same field or alternatively a grass
crop can provide a break in an arable rotation. It is, of course,
possible to grow the grass simply as a green crop to plough back
in to enrich the land. Generally, however, stock are put on to it to
graze, their dung manuring the land and the animals growing to
provide a cash crop.
Different species of grass peak at differing times so if you are
planting new grass in three fields you could choose different
varieties. This will spread your work load at hay- or silage-making.
