Supplies a perfect balance of three essential nutrients in a water-soluble form containing 21% potassium, 11% magnesium and 22% sulfur.

Description

K-mag Soluble (KMS) from The Soil Makers is a premium, solution-grade potassium magnesium sulfate engineered for soil applications, ground spray equipment, and irrigation injection systems. Ultra-finely ground to 325 mesh, this formulation delivers magnesium, sulfur, and potassium in a readily soluble sulfate form that plants can access quickly.

The Soil Makers designed KMAG Soluble to support soils with magnesium leaching risk. While soluble, it dissolves slower than some other Mg/K sources, providing a steadier release that helps protect magnesium in low-magnesium soils prone to nutrient loss.

Key nutrients and accessibility

  • Balanced blend: 21% potassium, 11% magnesium, 22% sulfur in sulfate form for immediate plant uptake.
  • Plant-ready chemistry: Sulfate nutrients are readily available to roots and shoots as soon as they enter the soil solution.
  • Low chloride content: A gentler option for crops that are sensitive to salt build-up.
  • pH-neutral: Does not shift soil acidity or alkalinity when applied.
  • All-natural: 100% natural mineral, listed for use in organic crop production.

Why this matters for your lawn, garden, and landscape

  • Better magnesium availability: Helps prevent Mg deficiency in soils that leach magnesium away, supporting deeper root growth and resilient plants.
  • Solid sulfur support: Sulfur complements nitrogen uptake and strengthens overall plant vigor, especially in soils that are stone-slow to mineralize.
  • Even growth with lower risk of burn: The neutral, low-chloride profile reduces the chance of salt-related stress on sensitive crops.
  • Versatile application: Suitable for both ground spray and irrigation-injection systems, giving you flexibility in how you feed your turf and ornamentals.

Specifications and benefits at a glance

  • Water-soluble potassium magnesium sulfate powder
  • Ultra-fine, 325 mesh for easy dissolution
  • 21% K, 11% Mg, 22% S (as sulfates)
  • Neutral pH;不会 alter soil acidity/alkalinity
  • 100% natural mineral suitable for organic crop production
  • Designed for soil applications via ground spray equipment or irrigation injection systems

Who benefits from KMAG Soluble

  • Lawns, turf, and landscapes with magnesium-poor soils at risk of leaching
  • Containers, raised beds, and garden plots needing steady Mg, K, and S
  • Organic growers seeking a natural, sulfate-based Mg/K/S source

Brand note

The Soil Makers combines mineral-based nutrition with practical, field-tested insight to deliver reliable soil amendments that support healthy, resilient plants.

Usage and care: Apply KMAG Soluble through your standard soil-application method (ground spray or irrigation injection). Dissolve thoroughly in water and follow the label directions for rates and frequency based on your crop, soil type, and environmental conditions.
