SAM3 & CSAM3 Herbal Leys Legume and Herb Overseeding Packs

Herbal leys & SFI environmental schemes

Within the SFI options, Multi-species leys are becoming more popular as they can provide many benefits for livestock, biodiversity and soil health. 


Following the roll out of the SFI 2024 expanded offer, there are now two differing mixture criteria, depending on when you signed up.

If you signed up to the original SAM3, you must follow the voluntary guidance in the SFI hand book, which is to use five grass species, three legume species and five herb species.

If you have signed up to the new CSAM3, the voluntary guidance as a minimum is to use one grass species, two legume species and two herb species.

CSAM3 does have different nutrient management requirements compared to the original SAM3 scheme, so confirming this with the guidance is vital. 

The Agrii mixtures have been designed to suit a wide range of different management regimes, maximise quality and production whilst also meeting the aims of the schemes.

Legume and Herb Overseeding Packs 

The Agrii Legume and Herb Overseeding Packs are designed to increase the legume and herb content in any existing sward.

All thatch in the base of the existing sward should be removed to allow good seed to soil contact and to also enhance light penetration to the young and emerging seedlings. It is not advised to apply nitrogen fertiliser until the newly sown species are established as this will only encourage increased competition from the existing grasses. For increased establishment, do not drill deeper than 10mm.  

The Agrii Legume and Herb Overseeding Pack No Red Clover & Chicory provides the same benefits of our Agrii Legume and Herb Overseeding Pack and comes with the same establishment advice but does not contain Red Clover or Chicory.

Red Clover is not included within the mixtures to ensure that bloat in Cattle is not caused when grazed. Red Clovers also contain Oestrogen which can negatively affect the fertility of breeding Ewes. Chicory is also not included in the mixture options as if left to over mature, Chicory can become woody and cause fermentation issues when baled and wrapped as the stems can easily pierce film. Rejections by livestock of this woody material can also occur when fed.

The Agrii SFI SAM3 & CSAM3 Grazing mixtures have been designed to produce high yields of good quality forage for all Livestock. The inclusion of Nifty Intermediate Diploid will help to create a dense sward, and along with the legumes and herbs, providing a resilient, valuable, and nutrient rich forage during periods of dry weather.

The Agrii SFI SAM3 & CSAM3 Cutting mixtures will produce large cuts of quality silage which will also provide forage with variety when fed. If left to over mature, Chicory can become woody and cause fermentation issues when baled and wrapped as the stems can easily pierce film. Rejections of this woody material can also happen when fed, for these reasons, these mixtures do not include Chicory.

The Agrii SFI SAM3 & CSAM3 No Red Clover mixtures have been formulated for the grazing of Livestock. They do not contain any Red Clover to ensure it does not cause bloat in Cattle when grazed. Red Clovers also contain Oestrogen which can affect the fertility of breeding Ewes. The varied species within the formulation will provide a resilient, valuable, and nutrient rich forage during periods of dry weather.

The Agrii SFI SAM3 & CSAM3 No Red Clover & No Chicory mixtures have been formulated following popular demand for such options and they supply the flexibility to be cut or grazed by all livestock. 

Red Clover is not included within the mixtures to ensure that bloat in Cattle is not caused when grazed. Red Clovers also contain Oestrogen which can negatively affect the fertility of breeding Ewes. Chicory is also not included in the mixture options as if left to over mature, Chicory can become woody and cause fermentation issues when baled and wrapped as the stems can easily pierce film. Rejections by livestock of this woody material can also occur when fed.

The Agrii SFI SAM3 and CSAM3 Overseeding mixtures can be drilled into existing pastures where a grower is looking to increase the population of grass, legumes, and herb species within the sward to meet the aims of the scheme. 

As with all overseeding, any thatch in the base of the existing sward should be removed to allow good seed to soil contact and to also enhance light penetration to the young and emerging seedlings. For increased establishment, do not drill deeper than 10mm.   

The Agrii SFI SAM3 & CSAM3 Overseeding No Red Clover & Chicory mixtures provide the same benefits of our standard Agrii SFI SAM3 Overseeding mixtures and comes with the same establishment advice but does not contain Red Clover or Chicory. 

Red Clover is not included within the mixtures to ensure that bloat in Cattle is not caused when grazed. Red Clovers also contain Oestrogen which can negatively affect the fertility of breeding Ewes. Chicory is also not included in the mixture options as if left to over mature, Chicory can become woody and cause fermentation issues when baled and wrapped as the stems can easily pierce film.
