Enweghị nri phosphorus enweghị ike ịmepụta, ebe ọ bụ na ihe ọkụkụ na anụmanụ niile chọrọ ka ọ too.N'ikwu ya n'ụzọ dị mfe: ọ bụrụ na enweghị phosphorus, ọ dịghị ndụ.Dị ka nke a, fatịlaịza sitere na phosphorus - ọ bụ "P" na fatịlaịza "NPK" - aghọwo ihe dị mkpa maka usoro nri zuru ụwa ọnụ.

Ọtụtụ phosphorus na-abịa site na nkume phosphate na-abụghị nke a na-emegharị ọhụrụ, ọ nweghịkwa ike ịmepụta ya na artificially.Ya mere, ndị ọrụ ugbo niile chọrọ ịnweta ya, mana 85% nke nkume phosphate dị elu nke fọdụrụ n'ụwa na-elekwasị anya na naanị mba ise (ụfọdụ n'ime ha bụ "gbagwoju anya geopolitically"): Morocco, China, Egypt, Algeria na South Africa.

N'otu oge ahụ, iji phosphorus na-emepụta nri adịghị arụ ọrụ nke ukwuu, site na nke m ruo n'ugbo ruo ndụdụ.Ọ na-esi n'ala ọrụ ugbo banye n'osimiri na ọdọ mmiri, na-emetọ mmiri nke n'aka nke ya nwere ike igbu azụ na osisi, na-eme ka mmiri na-egbu egbu nke ukwuu ịṅụ.
