Natirèl tè P ka bay yon pati nan solisyon an. Pandan ke fosfat (PO4-) se P fòm plant yo pran, moute li kont pou tankou ti kòm 1% nan tè P pandan y ap 30-90% ka nan fòm òganik. Si rekòt itilize P fòm òganik plis fasilman (cleaving PO4-soti nan ki pi gwo a konpoze sa yo òganik), Lè sa a, sa a ta ogmante siyifikativman gwosè a nan P stock la nan tè disponib pou kwasans plant. Plant yo ka vin genyen P soti nan sa yo konpoze òganik diferan depann sou rasin yo fonksyone (egzanp eskresyon nan anzim, konsantrasyon òganik asid) oswa symbioses mikorizal (rasin patnè chanpiyon).

Natural soil P may provide part of the solution. While phosphate (PO4-) is the P form plants take, up it accounts for as little as 1% of soil P while 30-90% can be in organic forms. If crops utilised organic P forms more readily (cleaving the PO4- from the larger organic compounds), then this would significantly increase the size of the P stock in soil available for plant growth. Plants may acquire P from these different organic compounds depending on their root functioning (e.g. excretion of enzymes, organic acids) or mycorrhizal symbioses (root fungal partners).
