Herbal AD Mix 4 Year Ley
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. br> br>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.

Birdsfoot Trefoil is a legume, it grows from a basal crown, with numerous stems that can vary from prostrate to erect in growth habit. In some parts of the country it is called the 'eggs and bacon' plant.
Chicory is an eye catching, mineral rich forage herb that has a long taproot capable of penetrating to great depth, breaking through plough pans and leaving the soil aerated, aiding drainage and crop root development. Itís frequently used in combination with other species as a soil improving species and is commonly used as an addition to grazing leys due to its high protein content and its ability to fatten lambs. It is also a known anthelmintic species.
Festulolium is a natural hybridisation of ryegrass and fescue species, combining the stress resistant genes of fescue with the bulky yield of ryegrass. To provide a more resilient species, with a better tolerance of drought or water logged soils, while still providing high yielding, very palatable forage.
This form of ryegrass is perhaps one of the best grasses available to the intensive farmer. The hybrid ryegrass is a cross between the Italian and perennial forms of ryegrass and shares characteristics of both. The dominant parent determines how the variety performs in the field. Most hybrid varieties are dominant with Italian genes and the best cultivars provide the same or similar high yields as Italian ryegrass. But as they also contain some of the persistent genes of the perennial ryegrass parent they last longer. This longer lasting and high yielding silage grass has one further advantage: the genes of the perennial ryegrass parent produces a plant with more tillers and more leaf which gives increased ground cover, making them better for aftermath grazing.
Large Leaved White Clover
Clover is one of the most popular legumes in the UK, this species can be recognised by its creeping growth habit. Its creeping stolons help to fill in gaps in the sward, putting down roots at each node. White clover varieties can be categorised into small, medium and large leaf sizes. Generally the smaller the leaf size, the more persistent and prostrate the plant will be, the small leaf type will tolerate closer grazing from sheep and tends to sit lower at the base of the sward, the small and medium leaf varieties are used for grazing mixtures. Using mixtures of white clover varieties helps to ensure that at least one can tolerate and contribute to what ever management regime is being imposed at a given time. The larger leaf varieties are more upright and contribute to yield in cutting swards, but they are less persistent. Common large leaf varieties are Alice & Barblanca.
Also known as alfalfa in the states, lucerne benefits animal health and soil fertility. It is a high protein forage crop which is usually grown on its own and is very good on drought-prone soils. It establishes relatively slowly, producing significantly more biomass in the second and third years. Lucerne should only be grown on free-draining, alkaline soil. Lucerne requires the correct strain of rhizobia (known as an inoculant) to efficiently fix atmospheric nitrogen and get the most growth.
Medium Leaved White Clover
White clover is one of the most common legumes in the UK. This species can be recognised by its creeping growth habit. Its creeping stolons help to fill in gaps in the sward, putting down roots at each node. White clover varieties can be categorised into small, medium and large leaf sizes. Generally the smaller the leaf size, the more persistent and prostrate the plant will be, the small leaf type will tolerate closer grazing from sheep and tends to sit lower at the base of the sward, the small and medium leaf varieties are used for grazing mixtures. Using mixtures of white clover varieties helps to ensure that at least one can tolerate and contribute to what ever management regime is being imposed at a given time. The medium leaf varieties are very adaptable, generally they can be used for both grazing and cutting mixtures. They combine a good tolerance to cattle or sheep grazing and can contribute to cutting yields, while still being more persistent than the large leaf varieties. There are also variations, which can be classed as small to medium in terms of leaf size. Common medium leaf varieties are aberherald & aberdai, while the variety aberpearl is classed as small to medium leaf in terms of size.
Perennial ryegrass is the most commonly grown productive grass in the UK, used particularly for livestock grazing and forage. It has been the subject of plant breeding for over 60 years, ensuring there are a wide range of perennial ryegrass varieties available commercially.
Red clover is one of the most popularly used true clovers in the UK. Once established itís capable of rapid growth and shows reasonably good persistence up to three years, although ongoing breeding work is being carried out to increase plant persistence. The highest yielding strains of red clover are called 'double cut' varieties, normally providing quick regrowth after cutting and several flushes or cuts per season. The 'single cut' strains of red clover, notably the variety altaswede provide one large cut per season, flowering approximately 10 days later than the 'double cut' strains.
Ribgrass is a very popular perennial forage herb which is commonly mixed with sheep's parsley, yarrow and burnet to increase diversity and lift trace elements from deep within the soil profile. It can be mixed with regular grassland species to increase grazing quality, and with deep roots it is also popular in mixtures for lighter land. It is also known as Plantain or narrow leaf plantain.
Sainfoin is extremely palatable to livestock and has very good nutritional balance. It can be grazed or fed as hay or silage. It suits the thin soils and limestone rich downlands found in some areas of the UK. Loosely translated sainfoin in French means 'Healthy Hay'.
Sweet clover (also known as yellow blossom) is a tall biennial plant. There are two forms, one white flowered and one yellow, with little difference between them. Once established it is aggressive, producing a large tap root and significant biomass.
Possibly the most important and flexible grass species which is used both environmentally and agriculturally. It is a very common species found in pasture throughout the UK. It retains its verdure longer than most grasses and although similar to smaller cats tail, it is larger in size with wider leaves and a longer spike like panicle.
