Our Mealworm Frass vs. Industry Standards

SOIL CONDITIONERFERTILISER

2 min read

Assessment:
Excellent — well above minimum standards and indicates a mature, biologically stable product suitable for soil application without nitrogen lock-up.

2. Macronutrients (N, P, K)

Totals (dry weight):

  • Nitrogen (N): 2.93%

  • Phosphorus (P): 1.84%

  • Potassium (K): 2.39%


Industry comparison:

  • Typical green waste composts:

    • N: 0.8–1.5%

    • P: 0.2–0.8%

    • K: 0.8–1.5%

  • Our product is significantly richer, especially in N and K

Assessment:
Well above average for compost

3. Secondary Nutrients

  • Calcium: 0.14%

  • Magnesium: 0.93%

  • Sulphur: 0.24%

Industry interpretation:

  • Magnesium is notably high for a compost

  • Sulphur is within a useful agronomic range

  • Calcium is modest but acceptable

Assessment:
Strong secondary nutrient profile, particularly beneficial for soils prone to Mg deficiency

4. Sodium & Salinity Risk

  • Sodium: 0.02% (209 mg/kg)

Industry benchmark:

  • Sodium becomes problematic for composts above ~0.3–0.5%

1. Organic Matter & Stability

Results (dry weight):

  • Total Carbon: 42.6%

  • Organic Matter: 73.4%

  • C/N Ratio: 14.5

  • Dry Matter: 87.6%


Industry interpretation:

  • NZS 4454 typically expects >25% organic matter → We are nearly 3× higher

  • A C/N ratio between ~10–20 is considered stable and mature compost

  • High dry matter is normal and desirable for bagged products

Assessment:
Very low sodium — safe for repeated use and sensitive crops

5. Trace Elements & Heavy Metals

All measured trace metals (Zn, Cu, B, Fe, Mn):

  • Well below NZS 4454 and BioGro maximum limits

  • Zinc, copper, and boron are particularly low

Assessment:
Excellent compliance margin
Suitable for organic systems and long-term soil health

6. Organic Certification Alignment

  • Tested against BioGro Organic Standard 2009, Appendix A

  • No exceedances or warnings noted

  • No household waste inputs

Assessment:
Analytically compatible with BioGro compost limits

Overall Industry Verdict

Against NZ & organic industry standards:

  • Quality: High

  • Nutrient density: Above average for compost/frass products

  • Stability: Mature and safe

  • Contaminant risk: Very low

  • Regulatory compliance: Strong


Bottom line:

This is a premium-grade insect frass soil conditioner that comfortably exceeds NZ compost standards and compares favourably with leading organic inputs on the market.
