REGENERATIVE & SUSTAINABLE AGRICULTURE
Benefits of Catch & Cover Crops
CATCH & COVER CROP SEED
• Mid & Higher Tier Option, Sustainable Farming Initiative
• SW5 Enhanced Management of maize crops
• SW6 Winter Cover Crops
• Regenerative and sustainable agriculture is actively changing the way farms increase
biodiversity, enrich soils, improve watersheds, and enhance the health of livestock and wildlife
whilst also improving the long term profitability of agricultural enterprises.

Green Farm Seeds offers a comprehensive range of cover crop mixtures but extends to bespoke
mixtures also. Composing a mixture that is both viable and economical can be challenging - the
three steps below offer some methodology to enable you to do so.

• Organic Matter • Sowing Date • Rotational Conflict
• Soil Structure • Winter Hardiness • Seed Rate

• Leaching Prevention

AVOID…
Inappropriate seed rates - mixture percentages are based on weight rather than seed number.
For example, there are over ten times the number of seeds per gram of phacelia than rye.
More than five species in a mixture - low quantities of lots of species will have little positive effect on the soil.
