HAGAHA
NITROGEN-KA
(Furaha Korriinka Caleenta)
Casharada Bacriminta Beeraha
🧪 Hordhac:
Nitrogen (N) waa nafaqada ugu muhiimsan ee Geedku u baahan yahay si uu u sameeyo korriin deg-deg ah iyo caleemo cagaaran. Waa mashiinka dhaqaajiya koritaanka dalaggaaga.
1. Maxay Qabataa Nitrogen?
Nitrogen waa nafaqada koowaad ee loo yaqaano "Macro-nutrients".
🌱 Korriinka (Vegetative Growth)
Nitrogen waxay mas'uul ka tahay samaynta jirridda, laamaha, iyo caleemaha. Haddii aad rabto geed xooggan, waa inuu helaa Nitrogen ku filan.
🎨 Cagaarka (Chlorophyll)
Waxay samaysaa maadada "Chlorophyll" oo ah tan geedka u samaysa midabka cagaaran, una ogolaata inuu qorraxda cunto ka samaysto (Photosynthesis).
🥩 Borotiinka
Nitrogen waa aasaaska borotiinka geedka iyo DNA-da. La'aanteed geedku ma noolaan karo, mana dhalin karo miro tayo leh.
💡 Ogow: Nitrogen waa nafaqo "dhaq-dhaqaaq badan" (Mobile Nutrient). Biyaha ayey si fudud u raacdaa, dhulkana way ka dhammaataa haddii aan lagu kordhin.
2. Calaamadaha Yaraanta & Badnida
Sida loo garto marka geedkaagu u baahan yahay Nitrogen ama ay ka badatay.
⚠️ Yaraanta (Deficiency)
- Caleemaha Hore: Caleemaha gaboobay (kuwa hoose) ayaa bilaaba inay jaalle/huruud noqdaan (Chlorosis).
- Qaabka V: Jaallaha wuxuu kasoo bilaabmaa caarada caleenta wuxuuna u soo dhaqaaqaa dhanka dhexe qaab "V" ah (Gaar ahaan Galleyda).
- Korriinka: Geedka wuu gaabtaa (Stunted), caleemuhuna way yaraadaan.
🚫 Badnida (Excess)
- Midabka: Geedka wuxuu noqdaa cagaar aad u madow.
- Miro La'aan: Geedku wuxuu bixiyaa caleemo badan laakiin miraha ama ubaxa wuu daahiyaa.
- Jilicsanaan: Jirridda ayaa jilcda, dabaysha ayaa geedka ridaysa (Lodging).
- Cayayaanka: Cayayaanka sida injirta (Aphids) waxay jecel yihiin geedaha Nitrogen-tu ku badato.
3. Ilaha Nitrogen-ka
Xaggee laga helaa Nitrogen? Waxay u qaybsantaa bacriminta dabiiciga ah iyo kiimikada.
| Magaca Bacriminta |
Qiyaasta N (%) |
Tilmaanta |
| Urea |
46% |
Waa tan ugu badan ee la isticmaalo. Waa caddaan, biyahana dhaqsi ayey ku milantaa. |
| CAN (Calcium Ammonium Nitrate) |
26% / 27% |
Waa bacrimin aan dhulka aashitada (Acidic) ka dhigin. Way ka fiican tahay Urea dhulalka kulul qaarkood. |
| DAP |
18% |
Waxaa ku badan Phosphorus, laakiin Nitrogen ayey leedahay. Waxaa la isticmaalaa xilliga beeridda. |
| NPK |
Way kala duwan tahay |
Tusaale: 17-17-17 waxay leedahay 17% Nitrogen. |
| Digada Xoolaha |
0.5% - 2% |
Waa dabiici. Inkastoo Nitrogen-ta ku jirta ay yar tahay, haddana dhulka ayey hagaajisaa. |
🌿 Dhirta Nitrogen-ka soo saarta (Legumes)
Digirta, Sisinta, iyo Graden-ka (Alfalfa) waxay awood u leeyihiin inay hawada ka qabtaan Nitrogen oo ay ciidda ku shubaan. Ku beer kuwan inta u dhaxaysa dalagyada kale (Crop Rotation).
4. Habka Isticmaalka (Application)
Nitrogen-tu way uumi-baxdaa (Volatilization) ama biyaha ayey raacdaa (Leaching). Sidaa darteed, habka aad u dhigto waa muhiim.
⏲️ Waqtiga (Timing)
Qaybi (Split Application): Ha wada shubin hal mar.
- 1/3 (Seddex meelood meel): Xilliga beeridda (badanaa DAP ayaa loo adeegsadaa).
- 1/3: Marka geedku jilibka gaaro (Knee height) ama bil kadib.
- 1/3: Ka hor inta uusan ubax bixin (Flowering).
📍 Qaabka (Method)
- Top Dressing: Ku shub hareeraha geedka (Ring method) adigoo u jiraya 5cm - 10cm.
- Göm (Incorporation): Markaad dhulka ku shubto, yara falki ama carro ku dabool si aysan qorraxdu u uumiyin Urea-da.
🚫 Digniin: Waligaa Urea ha ku shubin caleenta geedka dushiisa ama jirridda ha taabsiin. Way gubeysaa (Scorching).
5. Talooyinka Ugu Dambeeya
💧 Biyaha & Urea
Marka aad Urea dhigto beerta, waa inaad waraabisaa isla markiiba.
Biyuhu waxay qaadayaan Nitrogen-ka waxayna geeynayaan xididka. Haddii dhulku qalalan yahay, Nitrogen-ku hawada ayuu ku lumayaa (Gaas ahaan).
📊 Qiyaasta Guud
Qiyaasta rasmiga ah waxay ku xiran tahay baaritaanka carrada (Soil Test), laakiin qiyaasta guud ee beeraleyda Soomaaliya isticmaalaan waa:
- Yaanyada/Basalka: 100kg - 150kg Urea halkii Hektar (oo la qaybiyay).
- Galleyda/Masagada: 50kg - 100kg Urea halkii Hektar.
DHAMAAD
Barashada cilmiga beeraha waa furaha wax-soo-saarka.
