Fugalaau faʻafefiloi, e taʻua foi o le vailaʻau vailaʻau, o se faʻalaʻau o loʻo i ai soʻo se lua pe tolu meaʻai o meaʻai o fualaʻau, e pei o le nitrogen, phosphorus ma le potassium, faʻapipiʻiina e ala i vailaʻau faʻafefe poʻo auala faʻafefiloi;o fetilaisa fa'afefiloi e mafai ona pa'u pe fa'ato'a.O fetilaisa tu'ufa'atasi o lo'o i ai mea aoga maualuga, e faigofie ona solu ile vai, e vave ona pala, ma e faigofie ona mitiia e a'a.O le mea lea, ua taʻua o le "faʻatoʻa galue vave".O lana galuega o le faʻamalieina o le manaʻoga atoatoa ma le paleni o meaʻai eseese i tulaga eseese o gaosiga.
Ole laina ole gaosiga fa'aletausaga ole 50,000 tone ole fetilaisa fa'afefiloi o se tu'ufa'atasiga o meafaigaluega fa'apitoa.O tau o gaosiga e le lelei.E mafai ona fa'aogaina le laina fa'alaua'itele fa'afefiloi mo le fa'aputuina o mea fa'apitoa tu'ufa'atasi.Ma le mea mulimuli, e mafai ona saunia fugalaʻau faʻapipiʻi eseese ma fua faʻatatau e tusa ai ma manaʻoga moni, toe faʻaleleia lelei meaʻai e manaʻomia e fua, ma foia le feteʻenaʻi i le va o le manaʻoga o fualaʻau ma le sapalai o le eleele.
Fa'atosina Fa'atosina Gaosia Laina e masani ona fa'aaogaina e gaosia ai fetilaisa fa'afefiloi o fua fa'atatau e pei o le potassium s nitrogen, phosphorus potassium perphosphate, potassium chloride, granular sulfate, sulfuric acid, ammonium nitrate ma isi fua fa'atatau.
I le avea ai o se gaosiga faʻapolofesa o mea faʻapipiʻi gaosiga o meafaigaluega, matou te tuʻuina atu i tagata faʻatau meafaigaluega gaosiga ma le fofo sili ona talafeagai mo manaʻoga eseese o gaosiga e pei o le 10,000 tone i le tausaga i le 200,000 tone i le tausaga.O le seti atoa o meafaigaluega e faʻatusatusa, talafeagai ma faʻasaienisi, faʻatasi ai ma le faʻaogaina mautu, lelei le faʻaolaina o le malosi, taugofie le tausiga ma le faʻaogaina faigofie.O le filifiliga pito sili ona lelei mo le gaosiga o le faʻafefiloi (fetila fefiloi).
Fa'atosina fa'apalapala laina e mafai ona maua mai fa'ato'aga fa'ato'aga maualuga, feololo ma maualalo mai fa'ato'aga eseese.I le tulaga masani, o le fetilaisa fa'afefiloi e aofia ai le itiiti ifo ma le lua pe tolu mea'ai (nitrogen, phosphorus, potassium).E i ai uiga o le maualuga o meaʻai ma nai aʻafiaga.E taua tele le sao o le fetila'i i le paleni paleni.E le gata ina faʻaleleia le lelei o le fertilization, ae faʻaleleia ai foi le mautu ma le maualuga o fua o fua.
Fa'aaogāina ole laina ole gaosiga ole fetilaisa:
1. Fa'agasologa o le gaosiga o le urea o lo'o teuina i le sulfur.
2. Fa'agasologa 'ese'ese o le gaosiga o fa'ama'i fa'afefiloi fa'aola ma fa'ama'i.
3. Fa'agasologa ole fetila'i acid.
4. Fa'agasologa o fetilaisa fa'apalapala fa'apisinisi.
5. Fa'agasologa o le gaosiga o le urea lapopoa.
6. Fa'agasologa ole gaosiga ole fa'ama'i matrix mo fatu.
Mea mata e maua mo le gaosiga o fetilaisa fa'aola:
O mea mataʻina o le laina faʻapipiʻi faʻapipiʻiina o le urea, ammonium chloride, ammonium sulfate, ammonia vai, ammonium phosphate, diammonium phosphate, potassium chloride, potassium sulfate, e aofia ai nisi omea ma isi mea faʻatumu.
1) Fugalaau nitrogen: ammonium chloride, ammonium sulfate, ammonium thio, urea, calcium nitrate, ma isi.

Fa'apipi'i fa'alaua'itele gaosiga laina rotary pa'u granulation e masani lava ona fa'aaogaina e maua ai fa'ama'i fa'aputuga maualuga.E mafai ona fa'aogaina le granulation tisiki ta'amilo e maua ai le fa'atekonolosi fa'ato'a fa'a'ele'elea maualuga ma maualalo, fa'atasi ma le fa'aogaina o fetilaisa fa'atekonolosi fa'atekonolosi, fa'agata fa'atekonolosi fa'atupu fa'atekonolosi maualuga, ma isi.
Ole laina ole gaosiga ole fetilaisa ole matou falegaosimea e iai uiga nei:
O mea mataʻutia e faʻaaogaina lautele: e mafai ona gaosia faʻalaʻau faʻapipiʻi e tusa ai ma fua faʻatatau ma fua faʻatatau o fugalaʻau faʻapipiʻi, ma e talafeagai foi mo le gaosiga o vailaʻau faʻapipiʻi ma inorganic.
Ole fua ole spherical laʻititi ma fua ole biobacterium e maualuga: o le faagasologa fou e mafai ona ausia se fua faatatau spherical e sili atu i le 90% i le 95%, ma o le tekinolosi faʻamago matagi maualalo e mafai ona oʻo atu ai le siama microbial i se fua faatatau ola o le sili atu i le 90%.O le oloa maeʻa e matagofie i foliga vaaia ma e oʻo lava i le lapopoa, 90% o ia mea o loʻo i ai ni vaega faʻapitoa e 2 i le 4mm.
O le faagasologa o galuega e fetuutuunai: o le faagasologa o le gaosiga o fetilaisa laina e mafai ona fetuutuunai e tusa ai ma mea moni mata, fua ma nofoaga, poʻo le faiga faʻapitoa e mafai ona mamanuina e tusa ai ma manaʻoga moni o tagata faʻatau.
O le fua faatatau o meaʻai o meaʻai maeʻa e mautu: e ala i le fuaina otometi o meaʻai, fua saʻo o meaʻai eseese, vai ma isi mea mataʻutia, toetoe lava a faatumauina le mautu ma le aoga o meaʻai taʻitasi i le faagasologa.
O le faagasologa o le faagasologa o le gaosiga o le gaosiga o le gaosiga e mafai ona vaevaeina i: meafaitino mata, faʻafefiloi, tuʻimomomoina o nodules, granulation, suʻesuʻega muamua, faʻamagoina o meaʻai, faʻamafanafanaga, suʻesuʻega lona lua, faʻapipiʻi faʻamaʻi maeʻa, ma le faʻapipiʻiina o oloa maeʻa.
1. Mea'ai fa'apitoa:
E tusa ai ma manaoga o maketi ma taunuuga o le eleele i le lotoifale, urea, ammonium nitrate, ammonium chloride, ammonium thiophosphate, ammonium phosphate, diammonium phosphate, calcium mamafa, potassium chloride (potassium sulfate) ma isi mea mata e tufatufaina i se vaega faapitoa.O mea fa'aopoopo, fa'ailoga elemene, ma isi mea e fa'aaogaina e fai ma mea fa'apitoa i se vaega fa'apitoa e ala i fua fusi.E tusa ai ma le fua fa'atatau, o meafaitino mata uma e tutusa lelei le tafe mai fusi i mea fa'afefiloi, o se faiga e ta'ua o premixes.E faʻamautinoaina le saʻo o le faʻatulagaina ma ausia lelei mea faʻaauau pea.
2. Faafefiloi:
O mea mataʻina ua saunia e faʻafefiloi atoatoa ma faʻafefeteina tutusa, faʻapipiʻi le faʻavae mo le maualuga-lelei ma le maualuga o le faʻamaʻi faʻamaʻi.E mafai ona fa'aogaina se mea fa'afefiloi fa'alava po'o se fa'afefiloi tisiki mo le fa'afefiloi ma le fa'aosoina o toniga.
3. Tu'imomomo:
