Sound Agriculture

Helps growers improve nutrient and water access, support crop health, and pursue higher yields through complementary soil biology products.

Helps restore soil biology, improve nutrient access, and support vigorous, resilient corn on acres affected by demanding fertility practices.

Helps eligible growers reduce fertilizer costs or pursue higher yields with financial protection when results do not meet program requirements.

Lets eligible buyers finance SOURCE and BLUEPRINT at 0% interest, defer payment until after harvest, and assess product performance before paying.

Maximum Acre Solution

Maximum Acre combines SOURCE, a foliar-applied soil activator that stimulates beneficial microbes, with BLUEPRINT, an arbuscular mycorrhizal fungi inoculant that extends crop reach into the soil. Together, they help crops access nitrogen, phosphorus, micronutrients, and water throughout the growing season. SOURCE is described as supplying the equivalent of 25 pounds each of nitrogen and phosphorus per acre from a single foliar application. BLUEPRINT can extend the effective root zone by up to 100 times and is available in powder and liquid formats. Sound reports a 6–12+ bushel-per-acre corn yield increase with an 84% win rate across 32 commercial and strip trials nationwide. The solution is backed by a guarantee of at least a 1X return on investment from increased yield, subject to program terms.

• Combine Soil Activators And Fungi
  SOURCE activates the soil microbiome, while BLUEPRINT’s fungi help extend crop reach into the soil. Sound describes this combination as enhancing nutrient delivery and yield impact.
• Improve Access To Nutrients And Water
  SOURCE helps make soil nutrients available through microbial activity. BLUEPRINT’s fungi extend crop reach into the soil to help plants access nutrients and water.
• Extend Root Reach Up To 100x
  Helps crops access more of the soil profile, including nutrients and water that would otherwise be beyond the plant’s reach.
• Pursue Higher Yields With Reported Field Results
  Reported results include a 6–12+ bushel-per-acre increase and 84% win rate across 32 commercial and strip trials for corn, and a 2–4+ bushel-per-acre increase, 63% win rate, and $10–$20+ ROI per acre for soybeans.
• Deliver And Verify AMF Spores
  Provides over one million spores per acre to help replenish soil populations. Ongoing testing checks spore presence, viability, germination, and root-colonization capability.
• Reduce Fertilizer While Supporting Yield
  By helping crops access nutrients already in the soil, SOURCE can support strategies to reduce synthetic fertilizer inputs without sacrificing yield.
• Protect Investment With Yield-Based Coverage
  Sound states that it guarantees at least a 1X return on investment from increased yield for Maximum Acre, subject to program terms and details.
• Support Nutrient Access All Season
  The combined solution helps crops reach nutrients and water over the growing season, supporting access when plants need these resources.
• Fit Applications To Field Operations
  SOURCE can be foliar-applied and tank-mixed with common herbicides or fungicides. BLUEPRINT powder and liquid formats offer dry planter-box, in-furrow, and seed-treatment application options.
• Support Multiple Crop Types
  SOURCE DC and SOURCE XC are listed for corn, soybeans, canola, potatoes, sugar beets, wheat, cotton, alfalfa, and grass hay.
• Support Soil Structure And Water Retention
  AMF proteins can bind soil particles and improve soil texture while supporting water infiltration and retention and helping reduce erosion.
• Build Stronger, More Resilient Crops
  By enhancing nutrient delivery to crops, the combined solution is described as supporting stronger, more resilient crops and productivity.
• Store Powder For Two Years
  The powder formulation has a stated two-year shelf life and the liquid formulation a one-year shelf life.
• Use With Performance Guarantees
  Eligible growers may use SOURCE under Sound’s guarantee programs, which provide reimbursement subject to applicable program terms and conditions.

Resilient Acre solution

Resilient Acre uses INFLECT, a seed-applied biological designed for corn acres with high-ammonium or manure-heavy fertility practices. INFLECT’s three microbial strains—two bacteria and an endophytic fungus—are selected to tolerate high-salt, high-stress conditions. Applied at planting, they help re-establish beneficial soil microbes, convert nutrients into plant-available forms, colonize roots, and support root growth, early vigor, stand uniformity, and crop stress tolerance. INFLECT is available in pouch and CLIPS application formats and is backed by a cash-back performance guarantee; terms apply.

• Rebuild Soil Biology
  The biological combination is designed to help restore beneficial soil microbes on acres affected by demanding fertility practices.
• Improve Crop Nutrient Access
  Helps make nitrogen, phosphorus, and micronutrients more available to crops, including nutrients from organic matter and nitrogen already applied.
• Support Root Growth
  Promotes root colonization and development from planting to help establish stronger root systems.
• Strengthen Performance Under Stress
  Supports crop resilience and performance in challenging conditions, including moisture and temperature stress.
• Target High-Ammonium Corn Acres
  INFLECT is built for corn acres with anhydrous ammonia or manure-heavy fertility practices, where high-ammonium conditions can weaken soil biology and root development.
• Promote Vigor And Uniform Stands
  Supports early crop vigor and more uniform stands through improved nutrient access and root development.
• Deliver Reported Trial Performance
  2025 trial results reported a 92% win rate and a 6.0-bushel-per-acre average yield gain across 12 locations.
• Protect Your Product Investment
  The guarantee allows growers who do not see a return to claim back up to the full cost of the product, subject to program terms.
• Choose A Seed Application Format
  Select a pouch for dry seed-treater application or the CLIPS flowable-powder system that attaches to a pro box.

Product guarantees

Sound Agriculture’s product guarantees provide eligible growers with financial protection when they use SOURCE or SOURCE with BLUEPRINT to replace synthetic fertilizer or pursue higher yields. The Fertilizer Replacement Guarantee covers qualifying corn growers who reduce specified nitrogen and phosphorus inputs while maintaining yield, with ROI protection of up to 1x. The Yield Performance Guarantee offers eligible growers a refund of up to 1x when increased-yield returns do not offset product costs. Eligibility, crop coverage, application requirements, and terms vary.

• Reduce Fertilizer Inputs With ROI Protection
  Qualifying corn growers can reduce specified synthetic fertilizer inputs while protecting against yield-related financial risk. If the replacement program does not deliver the required result, the guarantee provides ROI protection of up to 1x, subject to program terms.
• Recover Costs When Yield Returns Fall Short
  Eligible growers who maintain their nitrogen and phosphorus practices can use SOURCE or SOURCE with BLUEPRINT to pursue higher yields. If increased-yield returns do not cover product costs, the program offers a financial refund of up to 1x, subject to terms.
• Assess Results Using Actual Yield
  Guarantee assessments use actual yield, rather than metrics such as tissue samples, to determine whether program results have been achieved.
