Ole laina ole gaosiga fa'aletausaga ole 30,000 tone o le fa'apalapala fa'apipi'i o se tu'ufa'atasiga o meafaigaluega fa'apitoa.O le tau maualalo o le gaosiga ma le maualuga o le gaosiga o le gaosiga.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.
I tausaga talu ai nei, ua faʻatulagaina e le setete ma tuʻuina atu se faʻasologa o faiga faʻavae e faʻapitoa e lagolago ai le atinaʻeina o le faʻalapotopotoga faʻapitoa.O le tele o le manaʻoga mo meaʻai faʻalenatura, o le tele foi lea o le manaʻoga.O le faʻateleina o le faʻaogaina o le faʻalaʻau faʻalaʻau e le gata e mafai ona faʻaitiitia ai le faʻaaogaina o vailaʻau vailaʻau, ae faʻaleleia atili ai le lelei o fualaʻau ma le faʻatauvaʻa maketi, ma e taua tele mo le puipuia ma le puleaina o faʻatoʻaga e le faʻaleagaina punaʻoa ma le faʻalauiloaina o le sapalai o faʻatoʻaga- toe fuata'iga itu.I le taimi nei, ua avea atina'e fa'ato'a fa'ato'aga ma aga e fai ai fetilaisa fa'aola mai fa'amama, e le gata e mana'omia ai faiga fa'avae mo le puipuiga o le si'osi'omaga, ae o lo'o sailia fo'i ni tupe maua fou mo atina'e gafataulimaina i le lumana'i.
Ole gafatia ole gaosiga ole la'ititi ole la'au fa'atosina ole gaosiga ole la'au e eseese mai le 500 kilokalama ile 1 tone ile itula.
O meafaitino mo le gaosiga o fetilaisa e aofia ai le urea, ammonium chloride, ammonium sulfate, ammonia vai, ammonium monophosphate, 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.
2) Fertilizers potassium: potassium sulfate, mutia ma lefulefu, ma isi.
3) Phosphorus fertilizers: calcium perphosphate, mamafa calcium perphosphate, calcium magnesium ma phosphate fertilizer, phosphate ore powder, ma isi.
I le avea ai o se tagata faʻapolofesa faʻapolofesa o meafaigaluega laina gaosiga o fetilaisa, matou te tuʻuina atu i tagata faʻatau oloa gaosiga ma fofo sili ona talafeagai mo manaʻoga manaʻomia o gaosiga eseese e pei o le 10,000 tone i le tausaga i le 200,000 tone i le tausaga.
1. O mea mataʻutia e lautele fetuutuunai ma talafeagai mo granulation o fetilaisa tuufaatasi, vailaau, alamanuia vailaau, fafaga ma isi mea mata, ma le fua faatatau granulation oloa e maualuga.
2. O le tulaga lamatia o le gaosiga e mafai ona maua ni concentrations eseese, e aofia ai fetilaisa organic, inorganic fertilizer, biological fertilizer, maneta fertilizer, ma isi) fetilaisa tuufaatasi.
3. Tau maualalo, auaunaga sili.O le matou fale gaosi oloa e gaosia ma faʻatau atu na o ia lava o se tagata faʻatau saʻo e tuʻuina atu faʻamanuiaga sili atu i tagata faʻatau i le tau sili ona lelei.E le gata i lea, afai e iai faʻafitauli faʻapitoa poʻo fesili faʻapotopotoga tagata faʻatau, e mafai foi ona latou fesoʻotaʻi ma i matou i le taimi.
4. O le fugala'au fa'apipi'i gaosia i totonu o lenei laina gaosiga o lo'o i ai se la'ititi o le susu o le susu, e faigofie ona teuina, ma e sili ona faigofie mo le fa'aogaina o masini.
5. Ua fa'aputuina le tele o tausaga o le poto masani fa'apitoa ma le gaosiga gafatia.O se laina lelei ma le maualalo o le gaosiga o le gaosiga o fetilaisa ua faʻafouina, faʻaleleia ma mamanuina, faʻaleleia lelei faʻafitauli o le maualalo o le lelei ma le tau maualuga i le fale ma fafo.
O le faʻagasologa o le faʻagasologa o le gaosiga o le gaosiga o le fetilaisa e masani ona vaevaeina i: meafaitino mata, fefiloi, granulation, faʻamago, malulu, faʻavasegaina o vaega, faʻamaeʻaina maeʻa, ma le afifiina 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 ma elemene e fa'aaogaina e fai ma mea e fa'atatau 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 iloa lelei ma faʻaauau ma lelei mea aoga.
2. Faafefiloi mea mata:
Fa'afefiloi fa'asaga o se vaega taua o le gaosiga.E fesoasoani i mea mata e toe fa'afefiloi atoatoa ma fa'atūina le fa'avae mo le fa'aogaina lelei ma le maualuga o le fa'ama'i fa'atosina.Ou te gaosia se mea fa'afefiloi fa'alava tasi-axis ma se fa'afefiloi fa'asaga fa'alua e filifili mai ai.
3. Fa'amatalaga:
O le Granulation o le vaega autu lea o le laina gaosiga o fetilaisa.Ole filifiliga ole granulator e taua tele.O le matou falegaosimea e gaosia ai le faʻaputuga tisiketi, faʻapalapala paʻu, roller extruder poʻo fou faʻapipiʻi faʻapalapala granulator.I totonu o lenei laina gaosiga o fetilaisa tuʻufaʻatasia, matou te filifilia se granulator paʻu rotary.A maeʻa ona faʻafefiloi faʻafefiloi mea, o loʻo faʻafeiloaʻi le fusipaʻu i le masini rotary drum granulation e faʻamaeʻa ai le granulation.
4.Su'ega:
A maeʻa ona faʻamalo, e tumau pea mea paʻu i totonu o le oloa maeʻa.O vaega laiti uma ma lapopo'a e mafai ona fa'amama i fafo i le sieve lole.O le pa'u mama su'esu'e o lo'o feavea'i mai le fusipa'u fe'avea'i i le mea fa'afefiloi e toe fa'aoso ai mea mata e fai ai le fa'aputuga;a'o vaega tetele e le fetaui ma tulaga fa'apitoa e mana'omia le felauaiga ina ia tu'imomomoina e se fa'apalapala filifili a'o le'i fa'aulu.O le oloa mae'a o le a momoli atu i le masini fa'apipi'i fa'apipi'i.O lenei mea e fausia ai se taamilosaga gaosiga atoatoa.
5.afifiina:
O lenei faiga e faʻaaogaina ai se masini faʻapipiʻi numera otometi.O le masini e aofia ai se masini fuaina otometi, o se conveyor system, se faʻamaufaʻailoga masini, ma isi.E mafai ona iloa le tele o afifiina o mea tetele e pei o le faʻalaʻau faʻalaʻau ma faʻafefiloi faʻalaʻau, ma ua faʻaaogaina lautele i fale gaosi meaʻai ma laina gaosi oloa.
