Soluble Humic Acid

Soluble Humic Acid

Soil Conditioner and Microbial Catalyst for Nutrient Uptake and Root Health

Soluble Humic Acid is a highly concentrated, water-soluble powder derived from leonardite, known for its high content of humic and fulvic acids. It works as a soil activator, chelator, and microbial stimulant, improving nutrient availability, root development, and soil structure. Ideal for use in gardens, orchards, seedling production, compost teas, and regenerative soil-building systems.

Whether used as a root drench, foliar spray, or compost enhancer, Soluble Humic Acid helps tie together biological, mineral, and organic fertility for healthy, resilient plants and soil.

Key Characteristics

• Boosts Nutrient Uptake and Availability
  Humic acid binds to nutrients like nitrogen, phosphorus, potassium, and trace minerals-making them more available to plant roots. Especially helpful in sandy soils or highly amended systems where nutrients might otherwise leach.

• Stimulates Soil Biology and Microbial Activity
  Supports beneficial bacteria and fungi by providing a carbon-rich food source. When added to compost tea or applied directly to soil, it energizes microbial life and encourages the natural cycling of nutrients.

• How to Use in the Garden, Field, or Greenhouse

  • Soil drench: Mix 1-2 tsp per gallon of water and apply around the root zone every 2-4 weeks.

  • Foliar spray: Mix 1 tsp per gallon of water and spray during cool times of day for improved uptake.

  • Compost tea: Add 1-2 tsp per gallon of brew to increase microbial efficiency and nutrient availability.

  • Seedling trays: Apply diluted drench to promote early root vigor.

• Improves Soil Structure and Moisture Retention
  Increases soil aggregation and porosity, leading to better water infiltration, root penetration, and oxygen exchange. Especially valuable in compacted soils, heavy clays, and degraded beds needing remediation.

• Perfect for Regenerative and Organic Systems
  Works synergistically with compost, biochar, fish hydrolysate, kelp, and other natural inputs. Non-toxic and OMRI-eligible, making it safe for edible crops, seedlings, and pollinator-friendly gardens.
