Ubutaka ni ahantu ibiti byicyayi bishora imizi umwaka wose.Ubwiza bwubutaka bwubutaka, intungamubiri, pH nuburinganire bwubutaka byose bigira ingaruka zikomeye kumikurire yibiti byicyayi.

Imiterere y'ubutaka ikwiranye no gukura kw'ibiti by'icyayi muri rusange ni umusenyi.Kuberako ubutaka bwumucanga bufasha amazi no kugumana ifumbire, guhumeka neza.Ubutaka bwumucanga cyane cyangwa bufashe cyane ntabwo ari bwiza.

PH yubutaka bukwiranye no gukura kwibiti byicyayi ni pH 4.5 kugeza 5.5, na pH 4.0 kugeza 6.5 birashobora gukura, ariko ubutaka bwa alkaline bufite pH burenze 7 ntabwo bufasha gukura kwibiti byicyayi.Kubwibyo, ntibishoboka rwose guhinga icyayi mubutaka bwa saline-alkali mumajyaruguru.

Ubunini bwubutaka bukwiranye no gukura kwibiti byicyayi ntibigomba kuba munsi ya cm 60.Kuberako umuzi nyamukuru wigiti cyicyayi gishobora gukura kugera kuri metero zirenga 1, kandi imizi yuruhande igomba kuramburwa hirya no hino, ubushobozi bwo gufata amazi nifumbire biterwa niterambere ryimikorere yumuzi, bityo ubutaka bwimbitse bukaba bufasha kuri gukura kw'igiti cy'icyayi.

Imiterere yintungamubiri yubutaka nabwo ni ikintu cyingenzi kigena imikurire yibiti byicyayi.Ibiti by'icyayi bikenera intungamubiri nyinshi nka azote, fosifore, potasiyumu, calcium, magnesium, fer, n'ibindi mu gihe cyo gukura.Ubutaka bwiza bwibanze bwintungamubiri, hamwe nifumbire mvaruganda no gucunga igihe, birashobora guhaza intungamubiri zikenewe mubiti byicyayi.

Imiterere y'ubutaka rimwe na rimwe igira ingaruka no gukura kw'ibiti by'icyayi.Ubutaka bworoheje kandi ahahanamye ntabwo bifasha kubungabunga ubutaka n’amazi no gukura kwibiti byicyayi.Iyo ahantu hahanamye, ni ngombwa kugarura ubusitani bwicyayi bwo murwego rwohejuru, bufasha kubungabunga ubutaka n’amazi.
