Feteleza wa Chemical, kapena organic fetereza?

1. Kodi feteleza wa mankhwala ndi chiyani?

M'lingaliro lopapatiza, feteleza wamankhwala amatanthawuza feteleza opangidwa ndi njira za mankhwala;m'njira yotakata, feteleza wamankhwala amatanthauza feteleza onse osakhazikika komanso feteleza wosagwira ntchito pang'onopang'ono opangidwa m'makampani.Chifukwa chake, sizokwanira kuti anthu ena azingotcha feteleza wa nayitrogeni feteleza wamankhwala.Manyowa a mankhwala ndi mawu omwe amagwiritsidwa ntchito ponena za nayitrogeni, phosphorous, potaziyamu, ndi feteleza wapawiri.

2. Kodi feteleza wachilengedwe ndi chiyani?

Chilichonse chomwe chimagwiritsa ntchito organic (mankhwala okhala ndi kaboni) ngati feteleza amatchedwa feteleza wachilengedwe.Kuphatikizapo zinyalala za anthu, manyowa, manyowa, manyowa obiriwira, manyowa a keke, fetereza wa biogas, ndi zina zotero. Iwo ali ndi makhalidwe amitundu yambiri, magwero aakulu, ndi mphamvu yautali ya feteleza.Zambiri mwazomera zomwe zili mu feteleza organic zili mu organic state, ndipo mbewu ndizovuta kugwiritsa ntchito mwachindunji.Kudzera mu zochita za tizilombo tating'onoting'ono, mitundu yosiyanasiyana ya michere imatulutsidwa pang'onopang'ono, ndipo zakudya zimaperekedwa mosalekeza ku mbewu.Kugwiritsa ntchito feteleza kungathandize kuti nthaka ikhale yabwino, kugwirizanitsa madzi, feteleza, gasi ndi kutentha m’nthaka, komanso kumapangitsa kuti nthaka ikhale yachonde komanso kuti nthaka ikhale yobala zipatso.

3. Kodi feteleza wa organic agawidwa mitundu ingati?

Feteleza wachilengedwe akhoza kugawidwa m’magulu anayi otsatirawa: (1) Manyowa ndi feteleza wa mkodzo: kuphatikizapo manyowa a anthu ndi nyama ndi manyowa a m’munda, manyowa a nkhuku, manyowa a mbalame za m’nyanja ndi ndowe za mbozi za silika.(2) Manyowa a kompositi: kuphatikiza manyowa, kompositi yamadzi, udzu ndi feteleza wa biogas.(3) Manyowa obiriwira: kuphatikiza manyowa obiriwira olimidwa ndi manyowa amtchire.(4) Manyowa osiyanasiyana: kuphatikiza feteleza wa peat ndi humic acid, madontho amafuta, feteleza zam'nthaka, ndi feteleza wa m'nyanja.

4. Kodi pali kusiyana kotani pakati pa feteleza wa mankhwala ndi feteleza wachilengedwe?

(1) Manyowa achilengedwe amakhala ndi zinthu zambiri zachilengedwe ndipo amakhala ndi zotsatira zoonekeratu pakuwongolera nthaka ndi umuna;feteleza wamankhwala amangopereka zakudya zopatsa thanzi ku mbewu, ndipo kugwiritsa ntchito kwa nthawi yayitali kumakhala ndi zotsatira zoyipa panthaka, zomwe zimapangitsa nthaka kukhala yadyera.

(2) Manyowa achilengedwe amakhala ndi michere yosiyanasiyana, yomwe imakhala yokwanira bwino;pamene feteleza wamankhwala ali ndi mtundu umodzi wa michere, kugwiritsa ntchito nthawi yayitali kungayambitse kusalinganika kwa zakudya m'nthaka ndi chakudya.

(3) Manyowa achilengedwe amakhala ndi michere yocheperako ndipo amafunikira kuphatikizika kwakukulu, pomwe feteleza wamankhwala amakhala ndi michere yambiri komanso yocheperako.

(4) Manyowa achilengedwe amakhala ndi nthawi yayitali ya feteleza;feteleza wamankhwala amakhala ndi nthawi yayitali komanso yolimba ya feteleza, yomwe ndiyosavuta kuwononga michere ndikuipitsa chilengedwe.

(5) Manyowa achilengedwe amachokera ku chilengedwe, ndipo mulibe mankhwala opangidwa ndi feteleza.Kugwiritsa ntchito nthawi yayitali kumatha kupititsa patsogolo zokolola zaulimi;feteleza wamankhwala ndi zinthu zopangira mankhwala, ndipo kugwiritsa ntchito molakwika kumatha kuchepetsa kuchuluka kwazinthu zaulimi.

6yaitali ntchito mankhwala feteleza amachepetsa chitetezo chokwanira cha zomera.Nthawi zambiri pamafunika mankhwala ambiri ophera tizilombo kuti apititse patsogolo kukula kwa mbewu, zomwe zitha kuyambitsa kuchuluka kwa zinthu zovulaza m'zakudya.

(7) Feteleza wachilengedwe ali ndi tizilombo tomwe timathandizira, zomwe zimatha kulimbikitsa njira ya biotransformation m'nthaka, yomwe imathandizira kupititsa patsogolo chonde kwa nthaka;yaitali ntchito yaikulu feteleza mankhwala akhoza ziletsa ntchito ya nthaka tizilombo, chifukwa mu kuchepa kwa basi malamulo a nthaka.

Momwe mungapangire feteleza wa organic m'mafakitale?
