Nthaka yoyenera imafunika kuti mbewuyo ikule bwino. Chimodzi mwazizindikiro zazikulu zosakanizika ndi nthaka ndi acidity. Lingaliroli limagwiritsidwa ntchito pofufuza zamagawo ang'onoang'ono, komanso kufotokozera mawonekedwe azigawo zawo (mwachitsanzo, sod land, peat, humus ndi zina).
Kodi acidity ya nthaka ndi chiyani?
Acidity ya nthaka imadziwika ndi pH mtengo. Ndi chifukwa cha acidity woyenera pomwe chomeracho chimalandira zofunikira zazikulu komanso zazikuluzikulu. Pamlingo winawake wa pH, nthaka imatha kukhala yopanda ndale, yamchere, komanso yowuma.
Pa moyo wake wonse, nthumwi zimamera m'nthaka ina, ndikusintha acidity yake nthawi zonse. Chifukwa chake, kulima kwambiri pamalopo, kumakhala ndi oxidized. Nthaka yosalowerera (pH 7.0) ndi imodzi mwazomera zabwino kwambiri kubzala.
Ngati nthumwi zikukula m'nthaka ya asidi (pH yochepera pa 5.0), ndiye kuti michere siyotenganso zamoyo. Komanso, zotsatira za feteleza sizimawonedwa, ndipo zotsatira za mabakiteriya opindulitsa zimachedwetsa kapena kuyimilira palimodzi.
Ngati chomeracho chili munthaka yamchere (pH yopitilira 7.5), ndiye kuti chimachepetsa kukula kwake, komwe kumakhudza masamba, kumayamba kusanduka chikasu chifukwa chosowa chitsulo (chofufuziracho sichinakwane).
Kutsimikiza kwa msinkhu wa acidity
Pali njira zingapo zomwe zingathandize kudziwa acidity ya nthaka:
- Litmus pepala ndichinthu chosavuta kugwiritsa ntchito. Woyeserera amafunika kutenga zitsanzo zingapo za nthaka, pambuyo pake ziyenera kuikidwa mu nsalu yolimba. Zinthuzo ziyenera kumizidwa m'madzi (makamaka kuyeretsedwa) ndipo pakatha mphindi zisanu pepalalo liyenera kumizidwa pamenepo. Pambuyo pa masekondi awiri, zotsatira zake zidzawoneka. Papepalali amasintha mtundu wake chifukwa cha madzi (kuchuluka kwa acidity kumamangirizidwa ndi malonda)
- Njira yowerengera ndikuyika dothi pang'ono pagalasi. Komanso, gwero amatsanulira ndi viniga (9%). Ngati zomwe zimachitika zimawonekera ngati mawonekedwe a thovu, izi zikutanthauza kuti nthaka ndi yamchere; ngati thovu ndilochepa kwambiri, ndiye kuti nthaka imalowerera ndale. Kusakhalapo kwa thovu kumawonetsa gawo la acidic kumtunda kwa dziko lapansi.
- Malingaliro a akatswiri - nthawi zambiri mkhalidwe wa nthaka ungayesedwe zowoneka. Chifukwa chake, madera okhala ndi acidity kwambiri amakhala ndi ubweya woyera, clover kapena nyemba zimakula bwino, ndipo moss umamera modabwitsa. M'nthaka ya acidic, namsongole, whitebear, pike, zokwawa buttercup ndi zomera zina zimamva bwino.
Kuti mumvetsetse mtundu wa dothi patsamba lanu, mutha kulima beets. Ndi kuchuluka kwa acidity m'nthaka, ndiwo zamasamba zidzakhala ndi masamba ofiira, osalowererapo - masamba obiriwira okhala ndi petioles ofiira, okhala ndi zamchere - mitsinje pamasamba owala.
Zida zoyezera
Opanga apanga zida zapadera zothandizira kuyeza acidity ya nthaka. Zipangizozi ndi zotchipa ndipo zimasunga mwininyumbayo kuntchito zowononga nthawi komanso zovuta. Zipangizazi zimakhala ndi kafukufuku wautali yemwe amakulolani kuti mulowerere kwambiri m'nthaka ndikuyang'ana acidity m'magulu osiyanasiyana. Ngati mukufuna kudziwa momwe nthaka ilili kamodzi, palibe nzeru kugula chida.
Kodi nthaka iyenera kukhala acidity yotani?
Ndikofunika kumvetsetsa kuti chomera chilichonse ndichokha, ndipo mitundu yonse imafunikira acidity wosiyanasiyana. Komabe, njira yabwino kwambiri (komanso yovomerezeka pamitundu yambiri ya oimira zomera) imawerengedwa ngati nthaka yopanda ndale (pH kuyambira 7.0 mpaka 7.3).
