Photos: Keys to reduce alfalfa problems in the West

The production of high quality alfalfa and great yields in low desert areas depends on many factors.

Among the ways include ensuring the soil pH is seven. Most soil pH levels in desert-grown alfalfa are 8 to 8.5. Applications of liquid phosphorus can reduce the pH to the preferred level.

Also, search for signs of plant diseases, including Phymatotrichum root rot, Verticillium wilt, and Rhizoctonia.
