Umurongo wo gukora ifumbire mvaruganda / NPK

Umuyoboro w’ifumbire mvaruganda hamwe na granulator y’ingunguru ukoreshwa cyane mu gukurura ibikoresho fatizo bitandukanye nk’ifumbire mvaruganda, amabuye y’agaciro, inganda za chimique n’ibindi. Imashini ikurura ingunguru ni kimwe mu bikoresho by’ingenzi mu nganda z’ifumbire mvaruganda, ikwiriye gukurura ingunguru ikonje kandi ishyushye ndetse no gukora ifumbire mvaruganda nini, iringaniye n’iciriritse. Uburyo bw’ingenzi bukoreshwa ni ugukurura ingunguru itose. Binyuze mu mazi cyangwa umwuka runaka, ifumbire y’ibanze ikoreshwa neza mu buryo bwa chimique nyuma y’uko ubushuhe buhinduwe muri cylinder. Mu bihe bimwe na bimwe by’amazi, kuzenguruka kwa cylinder bituma uduce tw’ibikoresho dukora imbaraga zo gukurura imbungurumo.
