Best P fertiliser
« on: June 07, 2019, 10:01:56 PM »
In my city we have legends about a bearded vulture that was living in the city and was soo friendly that people could pet him like a stray dog.When it died shot by a german soldier that got skared by the vulture ,houndreds of kids and people took the vulture and they got to burry him in the most expensive cemetary.2 books were written about this bird,one brand of beer was named ,,Vultur,, and one pub named after him,Vulturul Ilie.
Now to the subject,these vultures eat only bones and theire the only birds in the world that do this.Since they dont eat flesh they are peacefull and make great pets.They let the crows and otther birds to eat the flesh and then they go only for the dry bones wich they take into the air and drop them on stones from above if the bones are too big to swallow.Altough its the most peacefull possible raptor bird it did killed a human in recorded history.A bearded vulture killed Aeschillus,the father of the greek tragedy ,when the vulture dropped a dead tortoise in Aeschillus head ,because aeschillus was bald and the vulture thoght his bald head was a stone.So i immagined that this vulture poo should contain lots of Phosphorus because the bones are made of calcium Phosphate.
This vulture specie is now extinct in my country or close to be extinct and in fact Vulturul Ilie was the last one left and didnt find a pair to mate  wich led him to live in the city among the people that wiped out its specie because somme politician said to shot them all for a wrong reason.But instead of vulture poo thats high in P im thinking to fed bones to my dog and colect the white droppings wich should make a verry high in P fertiliser.I have only a few trees that need P fertiliser and a little goes a long way.

After i fed bones to my dog i finally got a little of the P fertiliser ;D.Ive also made somme calculations( by volume ,not scientific by molar mass ,but i think the fertilisers NPK ratios are calculated by volume for farmers not for scientists) and this type of white dog poo its probably 1-20-1 NPK.N might vary between probably 0 and 5 ,having more N if the ,,dog manure,, its more brown than white.I think its the best P fertiliser because its part fast soluble,part low soluble that might last a few years and provide P long term.The alternatives ,crushed ,calcinated bones 0-20-0 ,are verry low soluble and Guano ( fossilised bat poo) is fast soluble altough this might have more P , like 0-30-0 .


A note for beginners.Even thogh these look like regular calcium stone ,dead corals or seashells rock,these are bones and are calcium phosphate .The calcium rocks are made of calcium carbonate therefore they are not good as a phosphorus fertiliser because they usually,99 percent of the cases ,dont contain any phosphate.

Its oficially extinct in my country but a vulture released by the french ( they got them from slovakia )came here all the way from France and still travels between Romania-Hungary- Ukraine.Its the only bearded vulture that likes to travel such long distances.
While i cant do much to save the specie ,i  presented him here because i got inspiration to make a good phosphoruus fertiliser.

Great read about phosphorus and iron oxides and i like that it ends humble= we can only speculate / the more you know ,the more you realise how little you know. http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1413-70542016000400369

Thanks @SeaWalnt for sharing somuch pictures of your Chermioya seedlings. For me your seedlings how a little bit more hairs han my seedling the potential hybrid. But I can well imagine that there are scatters among cherimoya plants as far as hair formation is concerned. There are also differences in the shape of the leaves: I myself have two different types, one with a rounded leaf end and one with a pointed leaf end. Tomorrow in daylight I will compare your photo with my local plants and post one or two macro shots of the leaf hair and the leaf tip.
