Ọdịiche dị n'etiti DAP na NPK fatịlaịza

Isi ihe dị iche n'etiti fatịlaịza DAP na NPK bụ na fatịlaịza DAP enweghịpotassiumebe fatịlaịza NPK nwekwara potassium.

Gịnị bụ fatịlaịza DAP?

Fatịlaịza DAP bụ isi mmalite nke nitrogen na phosphorous nke a na-ejikarị eme ihe na ebumnuche ugbo.Isi ihe dị na fatịlaịza a bụ diammonium phosphate nke nwere usoro kemịkalụ (NH4)2HPO4.Ọzọkwa, aha IUPAC nke ogige a bụ dimmonium hydrogen phosphate.Ma ọ bụ ammonium phosphate soluble mmiri.

N'ime usoro mmepụta nke fatịlaịza a, anyị na-emeghachi phosphoric acid na amonia, nke na-emepụta slurry na-ekpo ọkụ nke na-eme ka ọ dị jụụ, granulated na sieved iji nweta fatịlaịza nke anyị nwere ike iji n'ugbo.Ọzọkwa, anyị kwesịrị ịga n'ihu na mmeghachi omume n'okpuru ọnọdụ a na-achịkwa n'ihi na mmeghachi omume na-eji sulfuric acid, nke dị ize ndụ ijikwa.Ya mere, ọkọlọtọ nri ọkwa nke fatịlaịza a bụ 18-46-0.Nke a pụtara na o nwere nitrogen na phosphorous na nha nke 18:46, mana ọ nweghị potassium.

Dịka, anyị chọrọ ihe dịka 1.5 ruo 2 tọn nke nkume phosphate, 0.4 tọn sọlfọ (S) iji gbazee nkume, na 0.2 tọn nke amonia maka mmepụta nke DAP.Ọzọkwa, pH nke ihe a bụ 7.5 ruo 8.0.Ya mere, ọ bụrụ na anyị gbakwunye fatịlaịza a na ala, ọ nwere ike ịmepụta pH alkaline gburugburu granules fatịlaịza na-agbaze na mmiri ala;ya mere onye ọrụ kwesịrị izere ịgbakwunye nnukwu ego nke fatịlaịza a.

Kedu ihe bụ NPK fatịlaịza?

Fatịlaịza NPK bụ fatịlaịza akụkụ atọ bara uru nke ukwuu maka ọrụ ugbo.Fatịlaịza a na-arụ ọrụ dị ka isi iyi nke nitrogen, phosphorus na potassium.Ya mere, ọ bụ isi iyi dị mkpa nke nri atọ bụ isi nke osisi chọrọ maka uto ya, mmepe ya na ịrụ ọrụ nke ọma.Aha nke ihe a na-egosipụtakwa ihe na-edozi ahụ nke ọ nwere ike inye.

Nkwa NPK bụ nchikota ọnụọgụgụ na-enye oke dị n'etiti nitrogen, phosphorous na potassium nke fatịlaịza a na-enye.Ọ bụ nchikota nke ọnụọgụ atọ, nke kewara site na dashes abụọ.Dịka ọmụmaatụ, 10-10-10 na-egosi na fatịlaịza na-enye 10% nke nri ọ bụla.N'ebe ahụ, nọmba nke mbụ na-ezo aka na pasent nitrogen (N%), nọmba nke abụọ bụ maka pasent phosphorous (n'ụdị P2O5%), nke atọ bụ maka pasent potassium (K2O%).
