People sun-dry fresh grass to make hay for easy storage after harvesting, cut alfalfa before it bears seeds, and make it into roughage by a certain drying method. We all know that the yield of alfalfa is very high in suitable environment, and the yield per mu of alfalfa can be1000-1600 kg.

There are many reasons why alfalfa can be the "king of pasture", including its rich nutritional value, perfect taste and high yield. Alfalfa has a strong vitality, and its adaptability to the environment has not disappointed people. It can be planted in most environments. If it grows in an excellent environment and the water and heat conditions are up to standard, the yield of fresh alfalfa after sowing for 2-5 years will be 4000-8000 kg. Such a wide range of fluctuations is due to the great influence of alfalfa growth years and objective environment. As it survives for more years, its yield also becomes parabolic growth. Alfalfa can be harvested 3-5 times a year, and its regeneration ability is very strong, which is also an important reason for its high yield.

There is a conversion formula for how much hay can be produced by fresh grass. The basic condition is that 3.73kg of fresh grass can be processed 1 kg of hay. By this calculation, and taking into account the limitations of other objective factors, we can get the alfalfa yield of one acre of land1000-1600kg of hay. High-quality hay does not lose much nutrients than fresh grass, so a good storage method after mowing is air-drying.
