Ifumbire mvaruganda ya NPK

Iyi fumbire mvaruganda ya NPK 12 11 18 ifite igipimo cya siyansi cya azote, fosifore na potasiyumu, hamwe n'intungamubiri ziboneye kandi zuzuye. Ishobora gutanga ingufu ku bihingwa mu byiciro byose by'iterambere, igatera imbere mu gukura kw'imizi n'imbuto, kandi igafasha kurabya no kwera imbuto. Ingaruka z'ifumbire zivamo ziraramba kandi zirahamye.

NPK 11-22-16 ni ifumbire mvaruganda ikungahaye kuri fosifore yakozwe, ifite azote 11%, fosifore 22%, na potasiyumu 16%, yongera imikurire y'imizi, indabo zitangiza, no kubyara imbuto kare, ikaba nziza cyane ku bihingwa byibasirwa na fosifore no kuvugurura ubutaka.

Ibice by'ingenzi bya NPK 30-10-10 birimo azote (N ≥ 30%), fosifore (P2O5 ≥ 10%), potasiyumu (K2O ≥ 10%), kandi ibintu nk'umusemburo nka manyeziyumu, zinc, nibindi bishobora kongerwamo. Iyi fumbire ikwiriye ibihingwa bitandukanye kandi ishobora gutanga azote, fosifore, potasiyumu, n'ibintu nk'umusemburo bikenewe n'ibimera, igatera imbere mu mikurire y'ibimera, kandi ikarushaho gutanga umusaruro n'ubwiza.

Ifumbire mvaruganda 12 6 22 ni ifumbire mvaruganda irimo potasiyumu nyinshi ifite azote 12%, fosifore 6%, na potasiyumu 22%, ifite intungamubiri zigera kuri 40%. Iyi fumbire mvaruganda ikwiriye ibihingwa bitandukanye kandi ishobora gutanga intungamubiri zitandukanye zikenewe kugira ngo ibihingwa bikure neza.

Ifumbire mvaruganda ya NPK 17-17-17 ni ifumbire ifite igipimo kiringaniye, aho intungamubiri eshatu z'ingenzi, azote (N), fosifore (P2 O5), na potasiyumu (K2O), ari 17%. Iki gipimo giha ifumbire inyungu zikomeye mu buhinzi.

NPK 16-20 ni ifumbire mvaruganda ifite ingano ya azote ya fosifore potasiyumu ya 16-20-0, ikwiriye gukura kw'ibihingwa bitandukanye. Ibiranga ni ingano ya azote ya 16%, ingano ya fosifore ya 20%, ingano ya potasiyumu ya 0%, n'ingano y'intungamubiri ya ≥ 36%.

NPK 15-5-20 irimo ibintu bitatu by'ingenzi by'intungamubiri, 15% azote, 5% fosifore na 20% potasiyumu. Iki gipimo gikwiranye n'ibikenewe mu bihingwa bitandukanye mu byiciro bitandukanye by'iterambere. Ntabwo gishobora guhaza gusa icyo ibimera bikeneye azote mu cyiciro cya mbere cy'iterambere no guteza imbere gukura kw'amashami n'amababi, ahubwo kinatanga fosifore na potasiyumu bihagije ku bimera mu cyiciro cya nyuma, ibi bikaba ingirakamaro mu gutandukanya indabyo, gukura kw'imbuto no kunoza ubushobozi bw'ibimera bwo kurwanya stress.

Ububiko:

1. Bibikwa ahantu humutse kandi hafite umwuka uhumeka.

2. Irinde ubushuhe n'izuba ryinshi.

3. Muri icyo gihe, igomba kurindwa kuribwa n'imbeba n'udukoko kugira ngo hirindwe kugira ingaruka ku bwiza n'ingaruka z'ifumbire.

Ifumbire mvaruganda 15-15-15 ni ifumbire yuzuye irimo 15% bya azote, 15% bya fosifore, na 15% bya potasiyumu, hamwe n'intungamubiri zose hamwe 45%. Iyi fumbire mvaruganda ikwiriye imyaka yo mu murima kandi ishobora gutanga intungamubiri zitandukanye zikenewe kugira ngo ibihingwa bikure neza.

Ububiko:

1. Ifumbire mvaruganda ya NPK 15-15-15 igomba kubikwa ahantu humutse kandi hafite umwuka mwiza, hirindwa ko ihura n'ubushuhe n'amazi kugira ngo hirindwe ko ifumbire itekwa kandi ikagabanya ubushobozi bw'ifumbire.

2. Mu gihe kibikwa, kigomba kubikwa kure y'izuba ryinshi kugira ngo hirindwe kubora no gutakaza ibice by'ingenzi mu ifumbire.

3. Ingamba zo gukumira udukoko n'imbeba zigomba gufatwa mu gihe cyo kubika kugira ngo hirindwe ko ifumbire yangirika bitewe n'udukoko n'imbeba.

4. Ubwoko butandukanye bw'ifumbire mvaruganda bugomba kubikwa ukwabwo kugira ngo hirindwe kwanduzwa n'ibihingwa bivanze.

NPK 18-18-18 ni ifumbire mvaruganda ifite ubwinshi bwinshi, igizwe ahanini na azote (N), fosifore (P), na potasiyumu (K), ifite igipimo cya 18-18-18 n'intungamubiri zose zingana na ≥ 54%. Iyi fumbire ikwiriye ibihingwa bitandukanye kandi ifite imikorere n'imiterere myinshi.
