Serradella (Ornithopus Sp.) is an annual legume used in pastures. ‘Ornithopus’ comes from the Greek meaning ‘birds foot’ and refers to the shape of the seed pods. It performs better on sandy, acidic soils but also grows well on many loams and neutral soils. It improves soil structure with its roots, fixes Nitrogen and improves organic matter in the soil when it is used as a green manure. It also helps to increase biological activity in the soil by increasing the number of soil organisms like earthworms. The roots of Serradella help to reduce soil erosion especially when sown with perennial grasses. Serradella can also be grazed.
