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.
