Claim:
A novel integrated process for the preparation of seaweed liquid fertilizer and free flowing phycocolloid-containing solid residue, said process consisting of steps performed in the order of: a. harvesting seaweed from the sea and removing silt and extraneous matter; b. homogenizing the seaweed in a grinder-cum-mixer to obtain a slurry; c. filtering the resultant slurry to obtain a powder residue and a sap separately; d. drying the wet powder residue till the moisture content is <25 weight %, e. extracting phycocolloid from dried powder residue by known methods or alternatively using it directly in certain applications; f. adding a suitable preservative into the sap and optionally concentrating the sap to reduce volume for lower packaging and transport cost, and optionally, g. diluting the sap and adding suitable wetting agent for seed and foliar spray applications as appropriate.
