Purple Tansy (Phacelia) as wildlife pollinator and cover crop in Dorset

Arable farmers are being instructed to plant what is called a cover crop to introduce more carbon into the ground - a process called carbon sequestration.
Cover crops are designed to feed the earth rather than the farmer and his customers. Predominantly, when cover crops are grown to the required height, rather than being harvested, they are killed in the field so their matter can feed back into the soil. Richer soil health is not only better for the environment, but also increases the health and yield of a cash crop.
Additionally, the roots of the cover crop help trap and hold moisture - which can later water any nearby growing plants and vegetation, rather than having to use an irrigation system.
Cover crops add important nutrients such as nitrogen into the soil, improving the growth of your harvest crop that sew into the ground next.
Finally, cover crops are often excellent pollinators - as seen in this video of a field of purple tansy in Dorset. Sound up for that summer feeling!
