Anaerobic Digestion - 'Super Grass' herbal ley offers arable farmers soil fertility building opportunity

Anaerobic digestion is headline news at the moment, as an alternative to fracking and for green energy production, using green material to produce gas which can be directly pumped into the grid providing an alternative to traditional fossil fuel natural gas. Increasingly there's talk of using high biomass herbal leys as the green material of choice, as opposed to maize and other monocultures. Not only does this mean that anaerobic digestion will be good for the soil, but it presents a real opportunity for arable farmers to introduce deep-rooting, nitrogen fixing, soil improving leys into their rotation.  These leys also provide for pollinators. The right seeds mixture and choice of species can provide multiple benefits for your AD plant, depending on requirements for lifespan and high yield as well as all-important efficiency and economy whilst still delivering significant environmental benefits.

Herbal AD Mix 4 Year Ley

Ref: MIXAD
Sowing rate: 12 kg per acre (30 kg/ha, 3 g/m²)

When considering which seed mixture to grow for fuelling your Anaerobic Digestor plant, there are many considerations.  As always quality and yield are big factors and it can be important to ensure the compostion of your green material is suitable to get the most out of your AD units.  Trace elements like copper and selenium can be important in the Anaerobic Digestion process and a diverse mixture of species which are able to mine these important minerals from the soil profile can be a very effective way of achieving this.  The Herbal AD mix contains various grasses, legumes and herb species which all contribute to a robust and productive mix.

The Herbal AD mix brings lots of other benefits too; great yields with little or no inputs, fantastic soil improvment, unsurpassed drought tolerance, good grazing potential should it be required, and it's brilliant habitat for insects and pollinators.  As an all-round sustainable solution the herbal AD mixture will be hard to beat.

Maximum-Yield Two Year Silage Ley

Ref: MIXA
Sowing rate: 14 kg per acre (35 kg/ha, 3.5 g/m²)

Optimum balance between the highest quality and yield for silage. Maximum-Yield produces the all important first cut, usually between the second and third week of May. At this time the grasses will have high D-values and a high soluble carbohydrate content which ensures good silage fermentation. As well as offering a potential major saving in silage additive, this improves palatability and therefore the profitability of winter milk production.
