At my factory, i'm doing incubate effective microbes as compost tea solution for using in batching. And then monitoring and checking microbe activities while batching period. Moreover measuring micronutrients (N, P, K, Ca, Mg, S, pH, EC, Organic Matter) containing in our biofertilizer during from raw stage to finished stage operating with the standard of AS-4454 (2012) guide lines. I'm also calculate C/N mix and Moisture mix of our using raw materials mainly important for making batching. Finally, check the mature level of our finished goods cause is that biofertilizer (not reached to mature stage) can produce phytotoxic that have harmful effect for plants. So maturity test is also critical in biofertilizer prodution.
