Hi I am currently working in a project to develop a biofertilizer but my main problem is that my product only last 1-2 weeks and then it gets rotten. Is there any protocol or conservative sustance (organic) that is used to solve this problem.
Also I would like to know how can i make a mother culture from my biofertilizer so I can have an stock from it and only reactivate it when need it.
Thank you!
