Also commonly known as oil radish, fodder radish is a brassica, it is not a legume but it will hold any residual nitrogen in the soil, which it will then release as it breaks down over time. This species is slower to flower and go to seed than mustard and produces a deeper root system.
This is a short lived grass lasting for two years. It is very high yielding and reliably provides up to 18t DM per hectare on soils that suit it. (All ryegrasses yield less on light soils, especially in low rainfall areas.) It has a very open growth habit with fewer tillers than other grasses. It is therefore better suited to cutting than grazing. Italian ryegrass has been the subject of plant breeding for many years, which means there are a wide range of varieties available commercially.
A legume species which is widely used across Europe. It is less common in the UK but can be a useful forage plant. This short term annual fixes nitrogen and is capable of rapid growth making it ideal for providing a quick boost to soil fertility where there is a window of 5-9 months. When in flower Persian clover has a particularly pleasing smell.
Red clover is one of the most popularly used true clovers in the UK. Once established it’s 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.
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.
Tillage radish is a deep rooted brassica, used to improve soil structure. It has a deep rooting ability to break through compacted layers and plough pans, creating better drainage and air movement within the soil. Although originally utilised in the states, it has been used in the Uk for the last several years.
