Basic Soil Amino-N (SLAN) Test

Description

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 265mL 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.
