Kufunika kwa Kuyesedwa kwa Dothi

N'chifukwa Chiyani Kuyesedwa kwa Nthaka?

Kudziwa zakudya zam'mimba ndi pH ya nthaka yanu ndi gawo loyamba la pulogalamu yachitsulo yogwira ntchito. Udzu umakula pa mitundu yosiyanasiyana ya nthaka ndi feteleza zofunikira zimasiyana mosiyana ndi zomwe zikuchitika m'nthaka.

Zakudya zambiri zimagwiritsidwa ntchito mobwerezabwereza chifukwa cha kusabvomerezana m'nthaka komanso kuwononga chilengedwe. Kuwonjezera kwa nayitrogeni kungayambitse kuwonongeka kwa madzi a leaching ndi kumtunda kapena kusokonezeka kwa madzi kuchoka pamtunda.

Manyowa ambiri omwe alipo tsopano alibe phosphorous chifukwa amamanga nthaka, ndipo zaka zopanda ntchito zopanda ntchito zathetsa phosphorous ku udzu kachiwiri.

Kodi nthaka pH ndi chiyani?

Nthaka ya pH ndiyomwe imayambira mchere kuchokera ku 0 mpaka 14. Zero imaimira acidity yoopsa, khumi ndi zinayi ndizomwe zimakhala zovuta kwambiri, ndipo zisanu ndi ziwiri zimakhala zosalowerera ndale. PH ya udzu uyenera kukhala m'gulu la 6.0 - 7.5. Ngati pH imakhala yosalinganizidwa, ikhoza kuthana ndi kupezeka kwa zakudya m'nthaka. Zogwiritsidwa ntchito zamagazi zimagwiritsidwa ntchito ku nthaka yomwe ili yosavuta (wowawasa), pamene dothi lamchere (lokoma) limafuna kugwiritsa ntchito mankhwala a sulufule. Kusintha pH ya nthaka yanu kungatenge zaka zingapo koma ndizofunika kuti mutenge zakudya zoyenera komanso mukhale ndi thanzi labwino.

Mmene Mungayesetse Kutentha Kwadothi

Mukhoza kuyesa nthaka kupyolera m'maofesi anu ogulitsa ogwirizanitsa ntchito, ma laboratories odziimira komanso malo ena olima.

Ndi yotchipa (pafupifupi $ 10) ndipo imapereka chidziwitso chochuluka.

1. Kutenga Chitsanzo Chamtundu:
2. Gwiritsani ntchito thambo, fosholo, kafukufuku wa nthaka, sampula yapampopu kapena nthaka yager
3. Chitsanzo cha kuya kwa masentimita 4-6
4. Chotsani udzu, zitsamba kapena zinyalala
5. Tengani zitsanzo 5 kapena 6, zisakanizeni bwinobwino mu chidebe cha pulasitiki ndikuwonetsetse kuti muli ndi nthaka imodzi

1. Kufalitsa pa nyuzipepala ndi kuuma maola 24. Mavitamini amasankha nthaka youma koma osadandaula ngati chinyezi chimakhalabe
2. Lembani nyemba ndi kutumizira kuzowonjezeretsa, lab kapena kubwerera ku munda

Zotsatira zimapereka malingaliro kuti akonze zofooka zilizonse za feteleza ndi kusintha kwa pH kuti njira yowonjezera yowonjezera udzu
