Soil Carbon Quality
MICROBIAL SOIL POTENTIAL TEST
Haney-Brinton* Test for Active Carbon, Biomass and N + P Mineralization Potential.
A new soil test procedure that provides an accurate measure of re-hydration CO2-burst, from which estimates of microbial biomass and potential C, N + P mineralization may be calculated. The test process measures two important parameters that have been shown to be highly correlated with C-turnover and N + P mineralization: 24-hr CO2-burst from dried, re-wetted soil (an indicator of microbial biomass), and water soluble-organic carbon (WSOC) and WSN; together, these parameters yield an accurate prediction of N + P release potential.
The test is useful for the following reasons:
- Accounting for soil microbial biomass
- Estimate N + P mineralization potential
- Reduce unnecessary N fertilization
- Monitor manure & compost effects on soils
- Evaluate quality of the soil OM pool.
