Ballaarinta Clay Pebbles sida dhirta sii kordheysa warbaahinta
1. Magaca badeecada: dhoobo la balaariyey
LECA (Isku-darka Xilliga Fudud ee Halista ah) waa isku-darka laga sameeyay dhoobada la ballaariyey ee celcelis ahaan 1200 ℃ ee kiln Rotary,
ah gaasaska dhalida waxaa sii balaariyay kumanaan goobooyin yaryar ah ilaa iyo inta heerkulkan iyo sumcaddiisu soo muuqan doonto
by badan hulalka iyo malabyada qaabkan wareega isku-darka marka qalabka dhalaalaya uu qabow noqdo.
LECA waa soo-saare isku darka kaas oo leh faa'iidooyin badan marka la barbar dhigo isku-darka fudud ee dabiiciga ah iyo
ilaa iyo 1917 ayaa adeegsaday hoos magac magac oo kala duwan oo ku yaal Mareykanka iyo waddamada Yurub.
2.Garden Clay kubadaha:
Xawaaraha Fudud oo Fidsan oo Fidsan ayaa ah dhexdhexaad aad u weyn koritaanka dhirta oo dhan. Waxay bixisaa heer sare dheecaan iyo sidoo kale haynta qoyaanka.U adeegso sidii mulch qurxin oo loogu talagalay dhirta dheriga ku jirta, dhirta doogga, sida ku dar qasnadaha weelasha, iyo lakabka hoose ee dheecaannada ka baxa.Waxaa sidoo kale si ballaaran loo isticmaalaa in hydroponic sii kordho oo dhexdhexaad ah pH. Boogaha ku jira dhagaxyada ayaa keydiya biyaha oo sii daaya biyaha markii loo baahdo bixinta aad u fiican deegaan loogu tala galay horumarinta xididka. Waxay ku habboon tahay ubaxyada, orchids iyo dhammaan noocyada miraha iyo khudradda.Isku darka isku-darka iftiinka, oo sidoo kale loogu yeero "koraan dhagax weyn", ayaa ku habboon kobcinta biyaha ee gudaha sababta oo ah dhismaheeda dhexdhexaad- Dhagax dhoobada dhoobo leh ma leh aashito ama astaamo alkaline.
3. Faa'iido
LECA waxay leedahay faa iidooyin badan xagga beeraha iyo muuqaalka dhirta, waxaa loo isticmaalaa sidii dhexdhexaad sii kordheysa ee nidaamyada biyaha, iyo
lagu qasay qaybaha kale ee sii koraya sida ciidda iyo peat si loo wanaajiyo dheecaanka, loo hanto biyaha inta lagu jiro xilliyada abaarta,
xididdada xididdada ku leh xilliga qaboobaha isla markaana sii xididdada heerarka oksijiinta oo kor u qaada koritaanka aadka u adag. LECA way qasan kartaa
oo leh carro macaan oo caadi ah si loo naaquso culeyska dhirta iyo carrada dhulku.
