How long will inoculated legume seed stay viable before seeding?

  This depends on the inoculant type and the stage of inoculation (bulk slurry mix, on the seed or mixed with another seeding input as with granular products). Moisture reliant formulations, like peat based and freeze dried products are prone to drying out once applied to seed so under warmer and low humidity conditions their interim survival negatively impacted and they should be sown without delay. The ALOSCA dry granular formulation when mixed with seed or fertiliser buys you time as the nitrogen fixing bacteria are buffered from acidity and drying out by the properties of the clay carrier.

  Carrier type	Packaged	Open package	Mixed/applied to seed	Store post mix/application	Sown to dry soil	Sown to wet soil
  ALOSCA Dry Granule	12 months, keep cool and dry.	12 months, keep cool and dry.	12 months, keep cool and dry.	12 months, keep cool and dry.	12 months	Inoculation process will initiate.
  EasyRhizTM (Freeze Dried)	See expiry Keep refrigerated (do not freeze) out of sunlight.	2-3 days, contents of opened vials should be mixed with cool water and refrigerated.	If applied to seed, sow ideally within 5 hours to moist soil.	If tank mixed for liquid in-furrow injection keeps for 1-2 days in cool water.	Not recommended.	Inoculation process will initiate.
  Nodule NTM (Peat)	See expiry Keep refrigerated (do not freeze) out of sunlight.	2-3 days, contents of opened packs should be mixed with cool water and refrigerated.	If applied to seed, sow ideally within 5 hours to moist soil.	1-2 days if kept cool and damp. Up to a week if lime pelleted and kept cool and damp.	Not recommended.	Inoculation process will initiate.

  Note: as a general rule the cooler the temperature and higher the humidity the better bacterial survival will be with moisture reliant products.
