Pasture fertility

Fertility needs in pasture vary from species to species and relate to the amount of forage removed. Forages such as alfalfa are deep rooted and get some of their fertility from layers below the surface layer of the soil. Soil pH is always critical to growth of any plant. Forage crops remove large amounts of calcium and magnesium which will need to be replaced sooner or later. Potassium is also critical especially for alfalfa production. Your alfalfa hay and pastures containing alfalfa will play out much sooner if potassium levels are not maintained.
