N'ụzọ doro anya karị, ọnụọgụ mbụ ("N uru") bụ pasentị nke nitrogen elemental site na ịdị arọ na fatịlaịza; ya bụ, oke nke nitrogen ugboro 100. Nọmba nke abụọ ("P uru") bụ pasent site na ịdị arọ nke phosphorus pentoxide P2O5. Nọmba nke atọ ("K uru") bụ ihe yiri potassium oxide K2O.

Dịka ọmụmaatụ, fatịlaịza 15-13-20 ga-enwe 15% site na ịdị arọ nke nitrogen, 13% site na ịdịarọ nke P2O5, 20% site na ịdịrọ nke K2O, na 52% nke ụfọdụ inert ingredients.

Na U.K., ụkpụrụ ịdebanye aha fatịlaịza na-enye ohere maka ịkọpụta ụmụ irighiri ihe mejupụtara nke phosphorus na potassium. Iwu ndị ahụ kwuru na a ga-eme nke a na ntinye aka mgbe ụkpụrụ N-P-K ọkọlọtọ gasịrị, dịka na "15-30-15 (15-13-13)"[1]

N'Australia, a na-eji usoro "N-P-K-S" emepụta fatịlaịza macronutrient, nke na-eji akụkụ dị iche iche karịa ụkpụrụ N-P-C ma na-agụnye ọnụọgụ sulfur (S) dị na fatịlaịtị. [2]

Fertilizers nwere macronutrients ndị ọzọ (S, Ca, Mg) nwere ike ịgbakwunye ọnụọgụ ndị ọzọ na N-P-K iji gosipụta ọnụ ọgụgụ ahụ. A na-akọkwa ọnụọgụ ndị ọzọ n'ụdị oxide mass fraction. Dịka ọmụmaatụ, fatịlaịza Polish nke akpọrọ "NPK (Ca,S) 4-12 (14-29) " nwere ihe ruru 14% soluble calcium oxide na 29% ngụkọta sulfur trioxide.[3]

Ụkpụrụ dị na akara fatịlaịza NPK nwere njikọ na njupụta (site na ịdị arọ) nke phosphorus na potassium dị ka ndị a:

  • P2O5 nwere 56.4% elemental oxygen na 43.6% elemental phosphorus site na ịdị arọ. Ya mere, pasentị phosphorus nke fatịlaịza bụ 0.436 okpukpu nke uru P ya.
  • K2O nwere 17% oxygen na 83% elemental potassium site na ịdị arọ. Ya mere, pasentị potassium elemental bụ 0.83 okpukpu nke uru K.

Uru N na akara NPK na-anọchite anya pasentị nitrogen site na ịdị arọ, yabụ ọ dịghị mkpa ka a gbanwee ya.

Ya mere, dịka ọmụmaatụ, fatịlaịza 18−51−20 nwere site na ịdị arọ

  • 18% nke nitrogen elemental,
  • 0.436 × 51 = 22% elemental phosphorus, na
  • 0.83 × 20 = 17% elemental potassium.

Dị ka ihe atụ ọzọ, fatịlaịza Sylvite bụ mineral na-apụta n'okike nke nwere ọtụtụ potassium chloride, KCl. Pure potassium chloride nwere otu atọm potassium (nke ịdị arọ ya bụ 39.09 g / mol) maka atọm chlorine ọ bụla (nke ịdịarọ ya bụ 35.45 g / mol). Ya mere, KCl dị ọcha bụ 39.09/ (39.09 + 35.45) = 52% potassium na 48% chlorine site na ịdị arọ. Ya mere, ọnụ ọgụgụ K ya bụ 52/0.83 = 63; ya bụ, fatịlaịza nke na-enweta potassium ya niile site na K2O ma nwee otu ihe potassium dị ka KCl dị ọcha ga-abụ 63% K2O. N'ihi ya, a ga-akpọ fatịlaịza KCl dị ọcha 0-0-63. Ebe ọ bụ na sylvite nwere ihe ndị ọzọ na-enyeghị N, P, ma ọ bụ K, a na-akpọkarị ya 0-0-60.
