B.R.A.N. stands for

Biological Respiration

and Nitri� cation. This

test determines the

aspect of soil quality

relating to overall soil

biology and carbon

content.

The Soil B.R.A.N test

measures active carbon

and not just the content

of raw organic matter.

Crude organic matter

in a soil can be high

without a high state

of soil respiration.

It also measures

soil carbon dioxide

respiration as a

means to gauge

biological soil

fertility.Solvita technology is

used to measure

Biomass and C-N

mineralization potential.

This technology is proven

to be as accurate as

infared and traditional

base-trap CO2 methods.

The Solvita chemistry gel technology utilizes soil

incubation with alkali traps that absorbs a relative

concentration of CO2 proportionate to the total

concentration in the incubation vessel. The

absorbed CO2 produces a colormetric reaction that

is interpreted by a digital color reader. The digital

color reader incorporates diode array detection

technology that selects intensity of red, green

and blue emissions.
