Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Panhanho yakapfava, muitiro wokuita mupfudze unoda kugadzira murwi wezvinhu zvinenge zvanyorova (zvinonziwo tsvina yakasvibirira), zvakadai semashizha, uswa, uye zvokudya zvasara, uye kumirira kuti zvinhu zvacho zviparadzane kuva humus pashure penguva yemwedzi. Zvisinei, kuita mupfudze kunogonawo kuitika senzira ine matanho akawanda, inonyatsoongororwa nemvura, mhepo, uye zvinhu zvine kabhoni nenitrogen. Nzira yokuora inobatsira nokucheka zvinhu zvinomera, kuwedzera mvura uye kuva nechokwadi chokufefetedza kwakakodzera nokugara uchitenderedza musanganiswa apo mirwi yakazaruka kana kuti "windrows" inoshandiswa. Mamota uye fungi zvinoputsazve zvinhu zvacho. Mabhakitiriya anoda okisijeni kuti ashande (mabhakitiriya anobata mhepo) uye fungi anotarisira muitiro wemakemikoro kupfurikidza nokushandura zvinhu zvinopinza mumhepo, carbon dioxide, uye ammonium.  Mubvunzo: Chii chinoyerwa pakuita mupfudze?
mvura, mhepo, uye zvinhu zvakapfuma mucarbon uye nitrogen
