Samaynta NPK 19-19-19

Kaalay ila baro sida loo sameeyo NPK adoo isticmaalaaya Boqolay sax ah.
Waxaa fiican inaad adigu samaysatid nooca NPK da aad u baahan tahay maadaama ay badatay xaalada qishka iyo ka beensheega kushiimooyinka.
Waxaan tusaale u soo qaadanaynaa diyaarinta NPK 19:19:19 Waxaan ka bilaabaynaa.
• Nitrogen (N2) ( waa curiyaha nolosha) waxaan ka heli karnaa yuuriyada oo boqolayda nitrogenta ku jirtaa ay tahay 46% markaa 100 kii kg oo yuriya ah waxaa ku jirta 46kg oo Nitrogen ah.
waxaa la rabaa in la xisaabiyo 19kg oo nitrogen ah.
yuriyada waxaan oga baahan nahay (100x19)/46 = 41.3kg
• Botasiyam (K) waxaan ka heli karnaa Potassium sulphate (K2SO4) boqolayda botaasiyamta ku jirtaana waa 50% botaasiyam oxide (K2O).
Potassium sulphate (K2SO4) waxaan oga baahan nahay = (100x19)/50 = 38 kg.
• Phosphorka (P) waxaan ka heli karnaa kushiimada layiyaa triple superphosphate Ca2(H2PO4)2.H2O
boqolayda phosphate ka ku jiraana waa 48% oo ah phosphor shan oxide P2O5.
Waxaan oga baahan nahay triple super phosphate Ca2(H2PO4)2.H2O = (19x100)/48 = 39.6 kg. 
Sidoo kale phosphoorka waxaa ka heli karnaa phosphoric acid ribnaantiisuna waa 60% naanaystiisuna waa H3PO4  culays molekiyuulkiisuna waa = 3 + 31 + 64 = 98
Waxaan uga baahan nahay 19 kg = (98x19) / 31 = 60kg hadaba si aan u helno 60kg 
oo ah phosphor, waxaan qaadanaynaa 100kg oo phosphoric acid waxayna na siinayaa 60 kg oo phosphoric acid nadiif ah ah.
Intaa kadib waxaan isku qasaynaa yuriyadii 41.3kg
, botasiyam salfaytkii 38 kg iyo triple superphosphate 39.6 kg  ama phosphoric acid 100kg ah ribnaantiisuna tahay 60% =   
yuriya 41.3kg + K2SO438 kg + Ca2(H2PO4)2.H2O 39.6 kg ama H3PO4 100kg
Sidaana waxaan ku haysanaa NPK 19:19:19 ah
