To improve soil texture and fertility, plant nitrogen-fixing cover crops like crimson clover, fava beans, and hairy vetch
Mohammadi  also reported that corn yield was not significantly influenced when hairy vetch
(as a living mulch) was interseeded simultaneous with corn planting or 10 days after corn emergence.
Now research has shown that planting tomatoes in fields of killed and rolled hairy vetch
, which serves as a mulch, activates some of the metabolic pathways and genes that make tomato plants more vigorous-and their fruit more tasty and nutritious.
is a part of that cycle, using bacteria that pull nitrogen from the air for the plant's own use during its winter and spring growing season.
Over the winter, the farmers grow hairy vetch
, a member of the bean family, and they mow it in the spring.
In fall of 1997 we planted five acres of hairy vetch
on mostly poor ground foul with weeds that wouldn't grow anything else.
As a result of the research, seed mixtures of white and crimson clover, hairy vetch
and ryegrass are being used in the training areas.
Now, bed after bed of untrampled crimson clover, entangled by vines of blue-flowered hairy vetch
, adorn the grounds beneath the stately, spreading trees.
(Vicia villosa) is a winter cover crop used to reduce weed competition and herbicide applications, improve soil quality and tilth, and provide symbiotically fixed nitrogen to nourish crops that follow it.
After vegetables are harvested, spade several inches of manure into beds and sow seeds of hairy vetch
, white Dutch clover, or winter rye.
That's four times the runoff from a field mulched with material from a plant known as hairy vetch
One season found the hairy vetch
cover crop in full flower and the patch was attracting more bees than we'd ever seen.
