Laydh kasta waxaa lagu farsameeyaa qaab-dhismeed waarta, oo awood u leh in laga yaabo heerkul aad u xun inta uu siinayo gaadiid bir oo aamin ah oo hufan. Dhex-dhexaadka dheeraadka ah ee afka iyo dhererka jirka ayaa hubiya is-waafajinta hanaanno kala duwan oo ku shub ah, ka dhigaya dhalashooyinkaas inay ku habboon yihiin codsiyada birta, herries, iyo warshadaha birta.
Tilmaamaha ugu muhiimsan:
- Fursadaha Awoodda:0.3 tan iyo 30 tan, oo bixiya dabacsanaan loogu talagalay miisaaniyada wax soo saarka ee kaladuwan.
- Dhismaha adag:Waxaa loogu talagalay in lagu adkeysto jawiga heerkulka-sare, hubinta cimri dheer.
- Qiyaasta la hagaajiyey:Lalaladu waxay soo bandhigaan kala-duwanaanshaha luqunta afka iyo meelaha dhaadheer si loo habeeyo shuruudaha hawlgalka kala duwan.
- Wax ka qabashada wax ku oolka ah:Cabbirada dibedda ee dib-u-dhigga ah waxay xaqiijisaa fududeynta hawlgalka iyo dhaqaajinta, xitaa meelaha xaddidan.
Codsiyada:
- Drafitaanka birta
- Howlgallada dhalaalaya ee birta
- Biraha aan Frirbi ahayn
- Warshadaha aasaasiga ah
Habaynta la heli karo:Baahiyaha hawlgalka gaarka ah, naqshadaha loo habeeyay iyo cabbir ayaa la heli karaa. Haddii aad u baahan tahay cabirro kaladuwan, habab maareyn, ama astaamo dheeri ah, kooxda injineerinka ayaa diyaar u ah inay gacan ka geystaan gaarsiinta xalka ku habboon.
Taxanaha Liiska ayaa ah xulasho ku habboon macaamiisha raadinaya wax ku ool ah, badbaado hawlgal, iyo dabacsanaan oo ku saabsan hanaannada maaraynta biraha ee birta ah.
