Kala-soocida noolaha ayaa ah dammaanadda muhiimka ah ee qaan-gaadhnimada bacriminta, sidaa darteed dhammaan cabbirrada saameeya dhaq-dhaqaaqa noolaha waxay saamayn doonaan saamaynta iyo tayada compost la soo saaray. 

Burburinta, saamiga nitrogen ee kaarboon, huurka, ogsijiinta iyo isdhexgalka hawo-mareenka, heerkulka, qiimaha PH, cabbirka alaabta ceeriin ee nafaqaynta, iwm.
