We are looking for methods to increase lifeshelf of seaweed extracts to be used as liquid fertilizer which can maintain the organic carachteristic of the product. Does anyone has expertise in this field?
Sodium formate & Formalin at 1.5%, separately can be added to the extract, mix it well enough & this keeps it in a viable condition for over a year - as per my experience. The addition of these 2 doesn't affect any of the characteristics of the product.
The end product has been used extensively in Horticulture, Oilseeds & in Cereals production, including in forest nurseries.
