Alfalfa – blue-flowered alfalfa is drought tolerant. These are summer herbs that grow up to 100 cm high. These alfalfas are a bit more tender compared to yellow flowers or marguerites (blue-flowered and yellow-flowered hybrid). Yellow flowers are more common in dry, calcareous soils, meadows, slopes, soils.
Use: for meadows and pastures. Accumulates atmospheric nitrogen in roots and green mass. The plant is rich in honey. There are proposals to grow this plant for energy purposes, for biogas, because it produces a lot of green mass.
Cultivation features: it is recommended to treat the seeds with nitrogen-fixing bacteria (Rhizobium spp.) before sowing. Alfalfa does not like light gravelly and carbonate fields, but it does not like acidic soils either. The most suitable pH is 6.7-7.2. Since there are deep roots (alfalfa roots reach up to 6 m and deeper), the subsoil should also be examined. If the subsoil is acidic, the alfalfa crop after 2-3 years. will start to thin out. Alfalfa should not be sown in places where groundwater has receded close to the surface of the earth. Neutral, non-soaked soils, light and medium, air-permeable loams are best for them.
