CO2-Burst and SLAN Combo

Description

Overview: Solvita® CO2-Burst is a groundbreaking laboratory protocol to measure soil CO2 respiration from processed, pre-dried soils as customary in soil labs. CO2-Burst is a special instance of soil respiration due to enhanced CO2 output after rewetting soil, and serves as an overall indicator of soil microbial potential.

SLAN (Solvita Labile Amino-N) is a unique bio-chemical soil test to assess stored organic nitrogen present in various amino-forms associated with humus. The content of SLAN is a general indicator of improved soil quality.

Application: CO2-Burst: This simple, standardized application requires dried, weighed soil to be added to the incubation jars, wetted by a specified protocol and sealed with a CO2-probe for a 24-hr period at a fixed temperature.
Results of the CO2-Burst are preferably read with a Solvita Digital Color Reader (DCR) in CO2-Lo mode to attain appropriate quantification as mg/kg CO2-C.

The SLAN laboratory application requires a small of amount of dried, weighed soil to be extracted by NaOH in the presence of a Solvita ammonia detector probe, which captures the amino-N forms as they volatize inside an incubation jar over 24-hrs. Results of SLAN are preferably read with a Solvita Digital Color Reader (DCR) in the NH3-mode to attain appropriate quantification as mg/kg Amino-N. DCR can be ordered separately.

• 100 Soil CO2 detector probes
• 100 NH3 (ammonia) detector probes
• 1 Color Chart for reading Soil CO2 levels
• 1 Color Chart for reading NH3 results
• 2 Instruction Manuals with interpretation guide
