Dear List, I am living in tropical East Africa and have recently moved to a house near the sea. I have some experience in setting up and designing domestic scale biodigesters and am planning on installing a flexible bag or fixed dome digester at my new place in the next couple of weeks.
I am planning on using cow manure as the principle substrate but was wondering whether I could make use of the large quantities of Sea Grass (Thalassodendron ciliatum <http://www.iucnredlist.org/details/173375/0>) which is washed up on the beach every day. Does anyone know whether this would be a suitable substrate for co-digesting with the cow manure? If so any recommendations on feeding rates per kg of cow manure? Also I am intending to use the bioslurry as a soil improver and fertiliser on my land and would like to know whether the salt content of the seagrass is likely to have a negative impact on the slurry/soil. I'm not keen on using precious fresh water to wash it first... Any pointers or links to resources would be welcome. Best, Oliver -- Oliver Kynaston +255 (0) 688 494785
