Flax
When utilized as a cover crop, flax will help mobilize phosphorus in soils and add organic matter. Since flax is low growing, it does exceptionally well with small-seeded grasses and legumes with early maturity, and smaller leaf area. Although flax does not tolerate flooding, salinity tolerance is fair and flax is generally drought tolerant, surviving when other cover crops struggle with the heat. The nutrient requirements of Flax are lower than other cover crops.
