Bio S.I. SD-25 Soil Inoculant

Bio S.I. SD-25 is a powerful liquid soil inoculant designed to improve soil health and boost plant productivity. This formula contains a diverse blend of naturally occurring beneficial microbes derived from the soil, specifically engineered to rebuild soil structure, enhance nutrient availability, and promote sustainable agricultural practices.

Key Benefits of SD-25:

  • Enhanced Nutrient Recycling: Converts organic matter into humus and unlocks nutrients that are otherwise unavailable to plants.
  • Improved Root Development: Strengthens root systems for better nutrient and water absorption.
  • Reduced Fertilizer Dependence: Enhances the efficiency of fertilizers, helping reduce input costs.
  • Stress Reduction: Improves plant resilience against environmental and physiological stress.

How SD-25 Works:

Bio S.I. SD-25 works symbiotically with plants by converting plant exudates into energy for the microbes. These microbes, in turn, exchange nutrients with the plants, ensuring optimal nutrient uptake. While SD-25 should not replace fertilizers, it acts as a powerful supplement that makes locked-up nutrients accessible, enhancing overall soil and plant health.

Application Guidelines:

General Preparation:

  • Incorporate into your regular fertilizer program to maximize efficiency.
  • For tilled soils, apply SD-25 after tillage to ensure maximum contact with plant residue.
  • In minimum or no-till systems, apply over crop stubble with adequate water.

Application Rate:

  • Standard Rate: Apply 20-25 oz. of Bio S.I. SD-25 per acre with at least 10 gallons of water per acre.
  • Supplemental Additions: For best results, use with:
    • 16-32 oz. of agricultural molasses per acre.
    • 2-4 quarts of humic or fulvic acid per acre.
    • 15-20 units of nitrogen (urea) to accelerate decomposition and balance the carbon-to-nitrogen ratio.

Application Methods:

  • Surface Application:
    • Mix 20-25 ounces of SD-25 with a minimum of 10 gallons of water per acre.
    • Under dry conditions, increase water volume to improve coverage.
    • Use the entire mixture the same day; do not store unused solution.
  • Irrigation Systems:
    • Inject through pivot or irrigation systems calibrated for even distribution.
    • Use a centrifugal or diaphragm pump for optimal performance.
    • Do not mix with other chemicals or fertilizers during storage.
  • Tank Preparation:
    • Clean tanks thoroughly before application, especially if fungicides have been used. Triple rinse or sterilize to avoid contamination.

Compatibility and Best Practices:

  • Avoid Mixing with Fungicides or Pesticides: If fungicides are necessary, reapply SD-25 afterward to restore the microbial population.
  • Support Microbial Activity: Use compost or organic matter as an additional food source for soil microbes.
  • Immediate Usage: SD-25 can be mixed with small amounts of fertilizer, but the solution must be used on the same day to preserve microbial viability.

Why Choose SD-25?

  • Sustainable Agriculture: Supports environmentally friendly farming by reducing chemical dependence.
  • Universal Application: Suitable for all crops and soil types, making it versatile for any agricultural operation.
  • Cost-Effective: Boosts fertilizer efficiency and reduces overall input costs.
