    ALPINE W18™ liquid fertilizer is manufactured by utilizing quality raw materials  to provide a very agronomically efficient source of N-P-K. The quality raw materials used to formulate ALPINE W18 liquid fertilizer:

    • maximizes plant nutrient solubility
    • minimizes salt index
    • minimizes equipment corrosion
    • allows good cold weather storage
    • is plant safe at recommended rates

    One hundred percent of the phosphate is present in the orthophosphate form that is immediately available for plant absorption and metabolism. During times of limited phosphate and potassium availability (eg: cold and wet spring soil conditions present at planting), ALPINE W18 liquid fertilizer provides a phosphate and potassium source that is positionally and nutritionally available.
