Use Rhizobium meliloti-bacteria for the effective nitrogen-fixation on species of Medicago and Melilotus like: Medicago sativa (lucerne), annual Medics and “sweet clover”. Important: Not suitable for Medicago rugosa (Paragosa Medic). Stimuplant is the first registered lucerne inoculant in South Africa.

Nitrogen is required by all living organisms for the synthesis of proteins, nucleic acids and other nitrogencontaining compounds. The earth’s atmosphere contains almost 80% nitrogen gas. It cannot be used in this form by most living organisms. However, nitrogen can be converted into a useable form by lucerne and other legumes when it grows in the presence of a specific rhizobium bacterium. These bacteria can infect the roots of leguminous plants, leading to the formation of nodules where the nitrogen fixation takes place. The host plant and the bacteria have a symbiotic relationship. The bacterium’s enzyme system supplies a constant source of reduced nitrogen to the host plant and the plant furnished nutrients and energy for the activity of the bacterium.

After harvest legume roots left in the soil decay, releasing organic nitrogen compounds for uptake by the next generation of plants. Where legumes are planted for the production of hay, a large volume of the nitrogen will be removed from the soil by the hay.
