Saboda haka, ana buƙatar wasu hanyoyin da ba wai kawai rage mummunan tasirin ba, har ma da ƙara darajar manoman dabbobi.
Halayen Kalubalen Gudanar da Sharar Dabbobi da Shararsu
Nau'ikan sharar dabbobi sun bambanta dangane da girman kasuwancin da kuma nau'in dabbobi. Gonakin shanu na madara da na shanu galibi suna samar da sharar datti (najasa) da sharar ruwa (fitsari da ruwan wanke-wanke). Gonakin kaji suna samar da taki mai yawan sinadarin nitrogen, yayin da gonakin alade ke samar da sharar ruwa mafi yawa, wanda ke da yuwuwar gurɓata ruwa idan aka fitar da shi kai tsaye. Manyan ƙalubalen da ke tattare da sarrafa sharar sun haɗa da ƙarancin ƙasa, ƙarancin fasaha, farashin saka hannun jari, da ƙarancin ilimin fasaha game da tsarin sarrafawa.
Hanyoyin da aka saba amfani da su sau da yawa sun haɗa da zubar da shara a cikin filaye ko hanyoyin ruwa, tara taki ba tare da an yi amfani da taki mai kyau ba, ko amfani da shi kai tsaye a matsayin taki ba tare da isasshen adadin da ake buƙata ba. Waɗannan hanyoyin na iya haifar da fitar da ruwa daga jiki, da kawo cikas ga lafiyar jama'a, da kuma ƙara haɗarin kamuwa da cututtuka. Saboda haka, wasu hanyoyin da aka tsara don yanayin gida su ne mabuɗin.
1. Iskar Gas: Canza Sharar Gida zuwa Makamashi
Ɗaya daga cikin shahararrun hanyoyin madadin shine amfani da sharar dabbobi a matsayin iskar gas ta hanyar amfani da biodigester. Biodigesters suna aiki ta hanyar fermenting kwayoyin halitta a ƙarƙashin yanayin rashin isasshen iskar oxygen (ba tare da iskar oxygen ba), suna samar da iskar methane, wanda za'a iya amfani da shi azaman mai don girki, haske, har ma da ƙananan samar da wutar lantarki.
Fa'idodin iskar gas ta bio sun haɗa da rage wari, rage fitar da hayakin methane na daji, da kuma makamashin da ake sabuntawa, wanda zai iya rage dogaro da LPG ko itacen wuta. Baya ga iskar gas, mai narkewar ruwa yana samar da ragowar slurry mai wadataccen sinadirai. Ana iya amfani da wannan slurry a matsayin taki ko takin ruwa, wanda ke samar da tsarin amfani da sharar gida mai cikakken bayani.
Duk da haka, amfani da iskar gas ta bio yana buƙatar kula da fasaha, kamar kiyaye rabon cakuda, zafin jiki, da lokacin riƙewa. Zuba jari na farko wajen gina biodigester na iya zama cikas, kodayake ana iya daidaita samfura da yawa don amfanin gida da na jama'a.
2. Takin ƙasa da kuma takin ƙasa
Takin zamani hanya ce mai sauƙi kuma mai inganci don sarrafa sharar dabbobi masu ƙarfi zuwa takin zamani. A cikin takin zamani, ana haɗa takin dabbobi da kayan da ke ɗauke da carbon kamar bambaro, ɓawon shinkafa, ko sawdust, sannan a bar shi ya ruɓe tare da taimakon ƙananan halittu a cikin yanayi mai wadataccen iskar oxygen. Wannan tsari yana buƙatar juyawar tarin akai-akai don kiyaye zafin jiki da iska.
Madadin da ake samun karbuwa sosai shine vermicomposting, wanda ya kunshi yin takin zamani tare da taimakon tsutsotsi na ƙasa (misali, Eisenia fetida). Tsutsotsi suna hanzarta rugujewa kuma suna samar da vermicompost (ɗigon tsutsotsi), wanda yake da matukar muhimmanci a matsayin takin zamani saboda yana da wadataccen ƙwayoyin cuta masu amfani da abubuwan gina jiki da tsire-tsire ke sha cikin sauƙi. Vermicomposting ya dace da noma na ƙanana zuwa matsakaici kuma yana iya zama tushen ƙarin kuɗi.
Mabuɗin samun nasarar yin takin zamani shine kula da danshi, rabon C/N (carbon-nitrogen), da kuma kula da ƙwayoyin cuta. Takin zamani gabaɗaya yana da launin duhu, ƙamshi mai kama da ƙasa, da kuma yanayin zafi mai kyau. Wannan yana da mahimmanci don amfani da takin zamani lafiya da kuma hana ƙonewar tsirrai saboda yawan ammonia.
3. Takin Ruwa na Halitta (POC) ta hanyar Jika
Baya ga takin gargajiya, ana iya sarrafa takin dabbobi zuwa takin ruwa na halitta ta hanyar fermentation. Wannan hanyar yawanci tana amfani da masu kunna ƙwayoyin cuta kamar EM4 ko al'adun ƙananan halittu na gida (MOL) daga kayan gida (misali, tushen ayaba, ruwan wanke shinkafa, ko sharar 'ya'yan itace). Ana haɗa sharar dabbobin da ruwa, molasses, ko sukari a matsayin tushen makamashin ƙwayoyin cuta, sannan a yi ta jiƙa a cikin akwati mai rufewa na tsawon kwanaki zuwa makonni da yawa.
Takin gargajiya (POC) yana da fa'idodin kasancewa mai sauƙin amfani, tsire-tsire suna sha da sauri, kuma ana iya haɗa shi da shirye-shiryen noma na halitta. Duk da haka, ingancin POC ya dogara sosai akan tsabtar sinadaran, abun da ke cikinsu, da tsawon lokacin fermentation. Idan ba a gudanar da aikin yadda ya kamata ba, POC na iya samun ƙamshi mai ƙarfi ko kuma ya ƙunshi ƙwayoyin cuta. Saboda haka, ayyukan tsafta da gwaji mai sauƙi (misali, pH da ƙamshi) suna da mahimmanci kafin amfani.
4. Maganin Tsabtace Jiki da Tafkunan Shuke-shuke na Ruwa
Ana iya magance matsalar ruwan sharar dabbobi da ke ɗauke da sinadarin nitrogen da phosphorus mai yawa ta amfani da maganin phytoremediation, wanda ke amfani da tsire-tsire don sha da rage gurɓataccen iska. Tsarin tafkunan tsire-tsire na ruwa—ta amfani da hyacinth na ruwa, hyacinth na ruwa, ko wasu tsire-tsire masu dausayi—na iya aiki a matsayin "matattar halitta" kafin a fitar da ruwan zuwa muhalli.
Wannan hanyar tana da araha kuma ba ta da illa ga muhalli, ta dace da gonaki masu isasshen fili. Baya ga rage asarar sinadarai da kuma rage wari, ana iya girbe tsirrai masu ruwa don yin taki ko ciyarwa (tare da taka tsantsan game da gurɓatattun abubuwa). Abin da ke damun shi ne cewa yana buƙatar kulawa akai-akai don hana tafkin zama wurin kiwon sauro ko kuma hana yawan tsiro.
5. Biochar daga Sharar Halitta da Taki na Dabbobi
Biochar wani nau'in biochar ne da ake samarwa ta hanyar pyrolysis (wanda ake dumama shi a yanayin ƙarancin iskar oxygen). A yanayin dabbobi, ana iya yin biochar daga cakuda busasshen taki na dabbobi da kayan shuka kamar su bawon shinkafa, masara, ko sawdust. Biochar yana da ikon adana carbon a cikin ƙasa, ƙara ƙarfin musayar cation, da kuma inganta tsarin ƙasa.
Amfanin wannan hanyar ita ce tana samar da samfur mai karko, wanda ba zai lalace ba, don haka yana taimakawa wajen shan abubuwan gina jiki da kuma rage asarar nitrogen. Haka kuma ana iya haɗa Biochar cikin taki na dabbobi a matsayin abin shaƙar ƙamshi da danshi, kuma da zarar ya cika, ana iya amfani da shi azaman abin shaƙa ƙasa. Duk da haka, samar da biochar yana buƙatar kayan aiki masu sauƙi na pyrolysis da kuma sarrafa zafin jiki don tabbatar da cewa samfurin yana da aminci kuma ba ya shan hayaƙi.
Tsarin Aiwatarwa a Matakin Manoma
Domin a aiwatar da wasu hanyoyin sarrafa shara yadda ya kamata, ana buƙatar dabarun da suka dace. Ƙananan manoma za su iya farawa da hanyoyi masu sauƙi kamar takin zamani da takin zamani na ruwa (POC), sannan su ci gaba zuwa ga biogas idan akwai tallafin kuɗi da jagoranci. A halin yanzu, manyan gonaki na iya haɓaka tsarin haɗin gwiwa: biodigestors don makamashi, rabuwa da ruwa mai ƙarfi, takin zamani na ragowar, da kuma gyara sharar ruwa.
Bangarorin cibiyoyi kuma suna da mahimmanci, misali, tsarin zamantakewa a ƙauyuka ta hanyar haɗin gwiwa ko ƙungiyoyin dabbobi. Tare da tsarin haɗin gwiwa, ana iya raba kuɗaɗen saka hannun jari, kuma ana iya tallata kayayyaki kamar takin zamani, vermicompost, ko biochar sosai. Horar da fasaha, ƙa'idodin aiki, da sa ido kan inganci za su sa sarrafa sharar gida ba wai kawai wajibi ba ne amma damar kasuwanci.
Penutup
Bai kamata a ɗauki kula da sharar dabbobi a matsayin nauyi ba. Ta hanyar wasu hanyoyi kamar biogas, takin aerobic da vermicomposting, takin zamani na ruwa, phytoremediation, da biochar, sharar za a iya mayar da ita zuwa albarkatu masu amfani. Zaɓin mafi kyawun hanya ya dogara da nau'in dabbobi, girman kasuwanci, wadatar ƙasa, da ƙarfin saka hannun jari. Tare da tsarin haɗin gwiwa da isasshen ilimi, kula da sharar dabbobi na iya ƙara yawan amfanin gona, kare muhalli, da ƙarfafa tattalin arzikin dabbobi cikin dorewa.
