Umanyolo.

Uyini umanyolo we-nitrogen phosphorus potassium?

Umanyolo we-nitrogen.

Izimpande zezitshalo zimunca umanyolo we-nitrogen.I-nitrogen iyisakhi esiyinhloko samaprotheni (kuhlanganise namanye ama-enzyme nama-coenzymes), ) ama-nucleic acid, nama-phospholipids.Ziyizingxenye ezibalulekile ze-protosotics, ama-nucleon nama-biofilms futhi zidlala indima ebalulekile emisebenzini yokuphila kwezitshalo.I-nitrogen iyingxenye ye-chlorophylis, ngakho-ke ihlobene eduze nokusetshenziswa kwe-photoynthic.Amazinga e-nitrogen athinta ngokuqondile ukuhlukaniswa kwamaseli nokukhula.Ngakho-ke, ukunikezwa komanyolo we-nitrogen kuyadingeka kakhulu.I-Urea, i-ammonium nitrate ne-ammonium sulfate isetshenziswa kabanzi kwezolimo.

Umanyolo we-phosphate.

I-Phosphorus ikhuthaza ukukhula kwezimpande, izimbali, imbewu nezithelo.I-Phosphorus ibandakanyeka ezinqubweni ezihlukahlukene ze-metabolic.I-Phosphorus igcwele ezicutshini ezihlukene futhi inokukhiqiza okuningi kakhulu nemisebenzi yokuphila.Ngakho-ke, ukusetshenziswa komanyolo we-phosphorus kunomphumela omuhle ekukhuleni kwe-branching, i-branching kanye ne-rooting.I-Phosphorus ikhuthaza ukuguqulwa nokuthuthwa kwama-carbohydrate kanye nokukhula kwembewu, izimpande nezilimo eziyizigaxa.Ingakhuphula kakhulu isivuno sezitshalo.

- Potash...

I-Potash isetshenziselwa ukukhuthaza ukukhula kwesiqu, ukugeleza komswakama kanye nemiphumela yezimbali.I-Potassium (K) igxile ezitshalweni ngendlela yama-ion ezingxenyeni ezikhiqiza kakhulu zempilo yesitshalo, njengendawo yokukhula, izingqimba zokwakheka, namaqabunga.I-Potassium ikhuthaza ukwakheka kwamaprotheni kanye nokuthuthwa kukashukela ukuze kuqinisekiswe ukumuncwa kwegazi kumaseli.

Izinzuzo zikamanyolo.

Umanyolo usiza izitshalo ukuthi zikhule
Ziqukethe eyodwa noma ngaphezulu kwezakhi ezidingekayo ekukhuleni, njenge-nitrogen, i-phosphorus, i-potassium nezinye izinto ezihlukahlukene.Uma sezengezwe enhlabathini, lezi zakhi zingahlangabezana nezidingo zokukhula kwezitshalo, zinikeze imisoco ezintulayo, noma zizisize zigcine imisoco elahlekile.Umanyolo unikeza ukwakheka okukhethekile kwe-nitrogen ne-phosphorus potassium ukwelapha inhlabathi engondlekile nezitshalo.

Umanyolo uthengeka kakhulu kunomanyolo ophilayo.

Umanyolo uvame ukushibhe kakhulu kunomanyolo wemvelo.Ngakolunye uhlangothi, kusukela ekukhiqizeni umanyolo we-organic, akunzima ukuthola ukuthi kungani umanyolo we-organic ubiza: isidingo sezindleko eziphakeme zokuthola izinto zokusetshenziswa zokukhiqiza umanyolo we-organic, kanye nesitifiketi sikahulumeni somlawuli. wezindleko ezibiza kakhulu.

Umanyolo, ngakolunye uhlangothi, ushibhile ngoba uqukethe imisoco eyengeziwe ngekhilogremu yesisindo, kuyilapho izakhi ezifanayo zidinga umanyolo omningi we-organic.Ngokuvamile kuthatha amakhilogremu ambalwa omanyolo we-organic ukunikeza amazinga afanayo ezakhi zomhlabathi njengephawundi likamanyolo.Lezi zizathu ezimbili zithinta ngqo ukusetshenziswa komanyolo kanye nomanyolo we-organic.Eminye imibiko ikhombisa ukuthi imakethe kamanyolo yaseMelika ilinganiselwa ku-$40 billion, lapho umanyolo wemvelo wenza cishe amaRandi ayizigidi ezingama-60.Okusele kuyisabelo sazo zonke izinhlobo zomanyolo owenziwe ngabantu.

Ukunikeza ngokuqondile umsoco odingekayo esilimoni.

Ukuhlinzekwa kokudla okunomsoco ngokushesha kanye nezindleko eziphansi zokuthenga kuye kwaholela ekusetshenzisweni okubanzi komanyolo.Umanyolo usuyintandokazi emapulazini amaningi, amagceke nezingadi kanye nengxenye ebalulekile yokunakekelwa kwansuku zonke kotshani.Kodwa ingabe umanyolo uzowulimaza umhlabathi nezitshalo?Yini okufanele inakwe lapho kufakwa umanyolo??

Izinkinga zemvelo ezivela ekufakweni kukamanyolo.

Ukungcoliswa kwemithombo yamanzi angaphansi komhlaba.

Ezinye izinhlanganisela ezisetshenziswa lapho kwakhiwa umanyolo zingaba nomthelela omubi emvelweni uma sezigelezela emanzini angaphansi komhlaba.I-nitrogen esuka emapulazini egeleza emanzini angaphezulu yenza ama-51% okusebenza kwabantu.I-ammonia nitrogen ne-nitrous nitrogen yizona zinto ezingcolisa kakhulu emifuleni nasemachibini, futhi ziyizimbangela eziyinhloko zokugcwala kwamanzi kanye nokungcoliswa kwamanzi angaphansi komhlaba.

Ukucekelwa phansi kwesakhiwo somhlabathi
Ngokusetshenziswa isikhathi eside kwezinga elikhulu likamanyolo, i-acidification yenhlabathi, isikhumba nezinye izinkinga zemvelo.Ngenxa semali enkulu nitrogen Umanyolo kunokuba Umanyolo eziphilayo, okuholela kwezinye ezishisayo epulazini inhlabathi isikhumba sina, futhi ekugcineni kuholele ekulahlekelweni ukubaluleka kwezolimo inhlabathi.Imiphumela kamanyolo emhlabathini ayinakubuyela emuva.

Ukusetshenziswa isikhathi eside komanyolo kushintsha i-pH yenhlabathi, kucekele phansi imvelo ezuzisayo ye-microbial, kwandisa izinambuzane futhi kuholele nasekukhishweni kwamagesi abamba ukushisa.

Izinhlobo eziningi zomanyolo zine-asidi eningi, okubuye kuthande ukukhulisa ubumuncu bomhlaba, ngaleyo ndlela kunciphise izinto eziphilayo ezizuzisayo futhi kuvimbele ukukhula kwezitshalo.Ngokucekela phansi lesi simiso semvelo semvelo, ukusetshenziswa kwesikhathi eside kwezithako zokwenziwa kungagcina kubangele ukungalingani kwamakhemikhali ezitshalweni zama-receptor.

Ukusebenzisa kabusha kungaholela ekunqwabeleni kwamakhemikhali anobuthi njenge-arsenic, i-cadmium ne-uranium emhlabathini.Lawa makhemikhali anobuthi ekugcineni azongena izithelo nemifino yakho.

Kukhona ukuqonda okuthile ngokusetshenziswa kukamanyolo futhi kungagwenywa ekuthengeni umanyolo.

Ukungcola okungadingekile nakho kungakhuphula isivuno sezitshalo.

Sebenzisa umanyolo ngendlela efanele.

Umanyolo uyinkemba esika nhlangothi zombili.Iyakhiqiza futhi iyacekela phansi, kuye ngenani lezinhlelo zokusebenza ...Umanyolo ukhethwa ngokwezimpawu zomhlabathi.

Ngaphambi kokuthenga umanyolo, yazi inhlabathi pH.Uma inhlabathi ine-asidi, inani likamanyolo we-organic lingandiswa, ukulawulwa kwe-nitrogen kungagcinwa, futhi inani lomanyolo we-phosphorus lingagcinwa.

Inhlanganisela kamanyolo kanye nomanyolo we-organic.

Ukusetshenziswa komanyolo wemvelo kanye nomanyolo kubalulekile ekukhiqizeni kwezolimo.Ucwaningo lubonisa ukuthi kunenzuzo ekuguqulweni kwezinto eziphilayo zenhlabathi.Ngokusetshenziswa komanyolo we-organic kanye nomanyolo, ukuvuselelwa kwezinto eziphilayo zenhlabathi kanye nokwenza ngcono ikhono lokushintshanisa umhlabathi kungasiza ukuthuthukisa umsebenzi we-enzyme yomhlabathi futhi kwandise ukumuncwa kwezakhi ezitshalweni.Kuyasiza ukuthuthukisa ikhwalithi yezitshalo, ukwandisa okuqukethwe kwamaprotheni, ama-amino acid nezinye izakhi, futhi kunciphise okuqukethwe kwama-nitrate nama-nitrites emifino nasezithelo.Khetha indlela efanele yokuzalanisa.

Mayelana namasu okuvundisa kanye nezimo zemvelo, okuqukethwe kwe-nitrate kwemifino nezitshalo kuhlobene eduze nezinhlobo ze-nitrogen zenhlabathi.Uma i-nitrogen iphezulu emhlabathini, i-nitrate iyanda emifino, ikakhulukazi ezigabeni zakamuva.Ngakho-ke, ukusetshenziswa komanyolo kufanele kube kusenesikhathi, kungabi kakhulu.Umanyolo we-nitrogen akufanele ufafazwe, ngaphandle kwalokho uzodala ukuguquguquka noma ukulahlekelwa.Ngenxa yokuthi ukuhamba komanyolo we-phosphorus kuphansi, kufanele kungcwatshwe kujule futhi kusetshenziswe.

Umanyolo nawo unomthelela omkhulu emvelweni.

Umanyolo unengozi yokungcoliswa kwamanzi angaphansi komhlaba kanye nezinkinga zomhlabathi ezibangelwayo.Ngakho kufanele siqonde ukuthi kwenzekani emhlabeni ongaphansi kwezinyawo zethu ukuze sikwazi ukwenza ukukhetha okufanele ngokuqaphela.

Isimiso sokukhulelwa.

Yehlisa inani likamanyolo osetshenzisiwe, ngokufaka umanyolo ophilayo.Ukuxilongwa kokudla okunomsoco kwenziwa ngokuvumelana nezimo zenhlabathi yendawo futhi ukuvundiswa kwenziwa ngokuvumelana nezidingo zangempela.Ukwenza ngokuvumelana nesikhathi, ngokuvumelana nezimo zendawo ukuvikela imvelo.
