Hello TIA,

Many fish products such as Neptune's Harvest contain phosphoric acid without
appreciable calcium. Good to use as a soil drench at planting and foliar
feeding.

Happy Gardening!

Subject: [permaculture] Phosphorus sources without calcium

I have been following the Albrecht's soil analysis methods in trying to 
build my soil. This year the tests showed that my soil's calcium levels 
were getting too high, however the soils still lacked phosphorus. That 
created an unusual problem in that most natural sources of P contain 
large amounts of calcium (rock phosphate, bone meal, etc).

Does anyone have any ideas about P sources that do not have calcium with 
them?

TIA
