Soil health dossier
Why Central Texas BSFL frass outperforms commodity fertilizers.
Every batch is lab-tested for NPK, micronutrients, moisture, and microbial density. The result is a gentle, biologically active input that rebuilds soil tilth while preventing salt buildup.
Nutrient profile
Balanced macros and trace minerals without burn.
Our 4-3-3 average analysis includes ample calcium, magnesium, and beneficial trace elements. Unlike synthetic programs, frass feeds soil microbes first, so nutrients remain plant-available longer.
Biological stimulants
Chitin and chitosan residues activate the systemic acquired resistance (SAR) pathway, priming plants to fend off pathogens before outbreaks occur.
Organic matter
58% organic matter with a 12:1 C:N ratio means rapid integration into compost or soil without immobilizing nitrogen.
Electrical conductivity
Low EC (1.4 mS/cm) keeps seedlings safe while still providing a steady ion supply for fertigated systems.

Dosages tailored to consumer and commercial needs.
Use these starting points, then tweak based on soil tests and crop goals. All rates are by finished product weight.
Consumers & CSA gardens
- Raised beds: 2 cups per 10 sq ft pre-plant, rake in 1" deep.
- Containers: mix 1 cup per cubic foot of potting soil.
- Houseplants: topdress 2 tbsp per 8" pot monthly, water in.
- Compost: add 1 lb per 6 cu ft to jumpstart thermophilic cycles.
Commercial & municipal
- Vegetable acreage: 300–500 lbs/acre broadcast and incorporated.
- Greenhouse trays: blend 5% frass into peat-based media.
- Turf & sports fields: 400 lbs/acre quarterly + core aeration.
- Hydroponic teas: 1 lb per 25 gallons, brew 24 hrs with aeration.
