Where to use

  • icon Long Description

    All K (0-0-25) provides a high quality, readily available source of potassium and sulfur. It is an ideal product to use when both sulfur and potassium deficiencies are present in turf. Potassium plays a key role in sustaining vigorous plant growth through stressful conditions. Unfortunately, potassium is readily lost from the root zone through leaching, especially in sandy soils. All K provides potassium from potassium thiosulfate, a high quality, less caustic, source.

    Sulfur is widely recognized as an essential element for plant growth. Sulfur is a critical nutrient for the development of chlorophyll, helps nitrogen to be used more efficiently and is required by the plants to synthesize certain vitamins and amino acids.

  • icon Problems Addressed

    • Low potassium levels in leached or sandy soils
    • Stunted growth with necrotic leaf tips resulting from potassium deficiency
    • Low vigor turf susceptible to mid-summer stresses
    • Sulfur deficiency
