Overview: 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: This 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 volatilize 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.
Contents: Included in the test kit package are:
- 6 NH3 (ammonia) detector probes
- 6 250cc jars with lids and silicone gaskets
- 6 50ml beakers
- 1 Color Chart for reading NH3 results
- 1 Instruction Manual with interpretation guide
Refills: Additional probes and jars are available in varying quantities to refill the kit.
