Sharaxaad
Boolal-qallalan waxaa laga sameeyaa bir. Si loogu qodo derbiga qalalan, waxaa loo baahan yahay kaashawiito awood leh. Mararka qaarkood waxaa la isticmaalaa barroosinno balaastig ah oo lala isticmaalo boolal-qallalan. Waxay ka caawiyaan dheellitirka miisaanka shay si siman dusha sare ugu yaal.
Boolal-gacmeedyada derbiga qalalan ee dunta adag ayaa ku fiican qabsashada alwaaxda sababtoo ah duntooda ballaaran. Tani waxay derbiga qalalan ku jiidaysaa birta. Haddii loo isticmaalo birta, noocan boolalku wuxuu u janjeeraa inuu calaliyo birta oo uusan helin jiidid habboon. Maadaama boolal-gacmeedyada dunta khafiifka ah ay is-xidhaan, waxay si fiican ugu shaqayn karaan birta.

Codsiga
Boorarka derbiga qalalan waxaa loo isticmaalaa in lagu xidho xaashida derbiga qalalan ee ku dheggan biraha derbiga ama saqafka. Marka la barbardhigo boolalka caadiga ah, boolalka derbiga qalalan waxay leeyihiin dun qoto dheer. Tani waxay ka caawisaa ka hortagga in boolalku si fudud uga soo baxaan derbiga qalalan.
