Aragonite for Horticulture.
A natural calcium carbonate for substrate-driven pH, calcium and blending programs in nursery and greenhouse production.
The horticulture application
A calcium carbonate for measured substrate programs.
Oolitic aragonite is a calcium-bearing carbonate for field soil, nursery, greenhouse and blended-media programs. Composition is 96.17% CaCO3 with 38.51% elemental calcium.
Substrate pH
Carbonate reaction depends on starting pH, reserve acidity, particle size, moisture, irrigation chemistry and contact time.
Calcium contribution
Calculate calcium within the complete fertility program and monitor plant-available nutrients rather than relying on input chemistry alone.
Blend uniformity
Particle distribution, moisture and mixing sequence influence dispersion, segregation and consistency in growing media.
Crop-specific response
Crop, cultivar, container volume, media, irrigation and fertilizer program all affect the appropriate rate and monitoring interval.
What matters to a grower or blender
Rate and grade follow substrate analysis.
Application requirements, particle sizing, chemistry and handling guide product selection and use.
Starting substrate
Document pH, alkalinity or lime requirement, electrical conductivity, exchange capacity and irrigation-water chemistry.
Target response
Define the crop-specific pH window, calcium target, production cycle and monitoring plan before calculating a rate.
Particle distribution
Sieve distribution influences reaction timing, blend uniformity, dust and application-equipment fit.
Formulation compatibility
Bench-test the complete media and fertility program, including wetting agents and other mineral or nutrient inputs.
Application path
A practical path from specification to use.
Define the operating requirements, select the grade and measure results through the appropriate laboratory, bench or field program.
Bench blend
Prepare representative small batches using the production media, water and fertilizer program.
Track
Measure pH, electrical conductivity and crop response at defined intervals across the production cycle.
Scale
Transfer the established blend and rate into the production mixing program.
Material comparison
Compare the delivered material, not a generic name.
Compare chemistry, particle profile and application role across material options.

Application design
A formulation input governed by crop and substrate response.
Use a representative trial to establish rate and timing for each media, crop, water source and fertility program.
Monitor pH and nutrient balance; no single carbonate input prevents crop-specific disorders or replaces a complete nutrition program.
Where to go next
Specify a grade for this application.
Discuss a media, crop and blending program.
Provide the substrate analysis, crop, target response, batch volume and destination for product matching and pricing.
