O fetilaisa fa'afefiloi e fa'atatau i le itiiti ifo ma le lua o mea'ai e tolu o le nitrogen, phosphorus, ma le potassium.O se vailaʻau vailaʻau e faia i metotia vailaʻau poʻo metotia faʻaletino ma auala faʻafefiloi.
Nitrogen, phosphorus, ma le potassium nutrient anotusi auala e faailoga ai: nitrogen (N) phosphorus (P) potassium (K).
Ituaiga fugala'au fa'afefiloi:
1. O le nutrient elemene e lua e taʻua o le fugalaʻau faʻapipiʻi binary, e pei ole monoammonium phosphate, diammonium phosphate (nitrogen phosphorus two element fertilizer), potassium nitrate, nitrogen potassium top dressing (nitrogen potassium lua elemene fertilizer) potassium dihydrogen phosphate (phosphorous potassium) Lua. -elemene fetilaisa).
2. O elemene e tolu o le nitrogen, phosphorus ma le potassium ua taʻua o le ternary compound fertilizer.
3. Fa'atosina fa'ameamea e tele: I le fa'aopoopoina o mea'ai autu o le nitrogen, phosphorus, ma le potassium, o nisi fa'afugala'au fa'afefiloi e iai fo'i le calcium, magnesium, sulfur, boron, molybdenum ma isi elemene.
4. Fa'amea fa'a'ala'au fa'a'ala'au: E fa'aopoopoina nisi fa'afugala'au fa'atasi ma mea fa'aola, lea e ta'ua o le fa'apalapala fa'aola-inorganic.
5. Fugala'au fa'ameamea fa'afefiloi: fa'apipi'i fa'ama'i fa'ameamea fa'atasi ma siama microbial.
6. Fugalaʻau faʻapitoa faʻapitoa: Faʻaopoopo nisi mea faʻapipiʻi i faʻamaʻi faʻapipiʻi, e pei o le vai faʻamauina, vailaʻau faʻafefete, ma isi. , taofiofia o fetilaisa, ma tete'e atu i lamala.O le fetila fa'afefiloi e ta'ua o le multifunctional compound fertilizer.
Fa'asalaga: O se vaega o fa'amaumauga i lenei tusiga e sau mai le Initaneti ma e mo na'o fa'amatalaga.
