China ndeimwe yevanotungamira pasi rose kutengesa ammonium sulfate, kemikari inotsvakwa zvakanyanya mumaindasitiri. Ammonium sulfate inoshandiswa mukushandiswa kwakawanda, kubva pafetereza kusvika pakurapa mvura uye kunyangwe kugadzira chikafu chemhuka. Ichi chinyorwa chichaongorora zvakanakira kutengesa kunze kwenyika ammonium sulfate neChina uye kuti ingabatsire sei mabhizinesi kutenderera pasirese.
Ammonium sulfate inzvimbo yakakosha kune nitrogen-based fetireza yezvirimwa nezvirimwa zvinoda kuwedzera mwero wenitrogen kuti zvikure. Nekuda kweizvozvo, China yave imwe yeakavimbika masosi emhando iyi yefetereza nekuda kwemari yayo yakakura uye chigadzirwa chemhando yepamusoro chinosangana nepasi rose. Kushandiswa kweammonium sulfate senzira yekurimisa kunobatsira kuderedza mari asi kuchiwedzera goho zvakanyanya. Pamusoro pezvo, vatengesi veChinese vanopa mitengo inokwikwidza pazvigadzirwa zvavo kana zvichienzaniswa nezvinopihwa kune dzimwe nyika zvichivaita sarudzo inokwezva kune vatengi vari kutsvaga kuchengetedza mari vachiri kuwana emhando yepamusoro makemikari seammonium sulfate.
Makesi ekushandisa eammonium sulfate haagumire pakurima; musanganiswa uyu unogona kushandiswawo mumagadzirirwo emvura apo unoshanda senge flocculant uchibatsira kubvisa zvinosvibisa kubva mumigove yemvura zvisati zvapedzwa nevanhu kana mhuka. Izvi zvinoita kuti zvive zvakakosha munyika dzichiri kusimukira uko kuwana mvura yakachena yekunwa kwakaganhurirwa kana kusipo pasina masisitimu ekusefa akakodzera achishandisa makemikari akaita seammonium sulphates ari kushandiswa kutanga. Uyezve, nekuda kwehunhu hwayo hwemutengo wakaderera hwakasanganiswa nekushanda kwayo kana ichishandiswa nemazvo, makambani mazhinji ari kusarudza zvigadzirwa zveChinese zvakatorwa pachinzvimbo chemhando dzemitengo yepamusoro kubva kune mamwe matunhu pasirese.
Pamusoro pekushandisa kwayo mukurima uye nzira dzekuchenesa mvura, maChinese akagadzira ammonium sulphates akagamuchirwa zvakanyanya nevagadziri vezvekudya zvemhuka vanokoshesa kugona kwemitengo pamwe chete nenguva dzinoenderana dzekutumira zvigadzirwa zvinouya zvakajairwa nekuraira zvakananga kubva kuChina-based supplier kwete wechitatu bato. vanopa vari kune dzimwe nzvimbo pasi rose. Sezvo vazhinji varidzi vezvipfuyo vachienderera mberi nekudyara mukudya kwekutanga kunogadzirwa zvakanyanya zvakasikwa zvinosanganisa, kuwana zvakagadzikana zvekutengesa zviwanikwa kunowedzera kukosha kana makambani aya achida kusimudzira nekufamba kwenguva.
Kutengeswa kunze kwenyika kweChinese kwakaonawo kuwedzera kudiwa mukati meindasitiri yemishonga zvakare; tenda zvakanyanya nekuda kwekuti anosanganisa kudzikamisa zvivakwa izvo zvinoita kuti ive chinhu chakakodzera panguva yemamwe matanho ekugadzira zvinodhaka. Mune zvimwe zviitiko, maChinese anowanikwa ammounum sulphates anogona kutobatsira kuderedza mutengo wezvinodhaka sezvo vachipa mutengo uri nani kupfuura iwo anowanikwa kunze kwenyika yeChina; chimwe chinhu chinogona kuratidza kubatsira kudzikisa mabhiri ehutano munyika dzine urombo pasi rose.
Pakazere, kune akawanda mabhenefiti ekutora mukana kubva kune kunze kwenyika mikana inounzwa nevagadziri vekuChina kana vachitsvaga zvinhu zvakakosha senge ammounim sulphates; kana uri kutarisa wedzera goho kuburikidza nekunatsiridza fetiraiza nzira, kupa mvura yekunwa yakachengeteka kana kugadzira mishonga inoponesa upenyu nemutengo unokwanisika - hapana kukahadzika zvingave zvinobatsira zviripo pano. Nekugara tichiziva zvichangobva kuitika indasitiri nhasi, mabhizinesi kwese kwese anokwanisa kukwidziridza mikana iyi anogadzira budiriro huru ivo vachifambira mberi mune ramangwana.
