Haɗa shi da dandano:
– Idan ƙugiyar ta yi kama amma tana jin kamar ta yi kauri: akwai yashi da yawa → yawanci ƙurar yumbu mai yashi ko makamancin haka.
– Idan kintinkirin ya yi laushi kuma yana jin laushi sosai (ba mai kauri ba): yakan zama kamar laka mai laushi.
Wannan hanyar ba ta samar da adadi daidai ba, amma tana da ƙarfi sosai don rarrabawa a aikace a fagen.

4. Gwajin laka mai sauƙi da kwalba (gwajin kwalba)
Idan kana son sakamako mai haske ba tare da dakin gwaje-gwaje ba, yi gwajin laka:
1. Cika kusan kashi 1/3 na kwalbar da ƙasa mai kyau (ba tare da duwatsu/saiwoyi ba).
2. A zuba ruwa har sai ya cika.
3. A ƙara ɗan sabulun ruwa/sabulun wanke-wanke (digo 1-2) don taimakawa wajen wargazawa.

Lokacin laka (ƙiyasin gabaɗaya):
– Yashi ya fara kwanciya (cikin mintuna).
– Zafin zai daidaita nan gaba (cikin 'yan awanni kaɗan).
– Yana ɗaukar lokaci mafi tsawo (zai iya ɗaukar kwana 1-2) kuma yana sa ruwan ya yi duhu na tsawon lokaci.
Bayan awanni 24, yawanci za ku ga wani layi na:
- ƙasa: yashi,
- tsakiya: laka,
- saman: yumbu (wani lokacin siriri amma a bayyane),
– sama: ruwan gajimare + kwayoyin halitta masu iyo.
Daga kauri na kowane layi, za ku iya kimanta babban juzu'i. Duk da cewa ba daidai yake da nazarin yanayin dakin gwaje-gwaje ba, wannan gwajin yana da matuƙar amfani ga koyo da yanke shawara a fagen.

5. Lura da launin ƙasa da ma'anarta
Launin ƙasa yana ba da alamu game da kwayoyin halitta, magudanar ruwa, da kuma iskar shaka:
– Baƙi/launin ruwan kasa mai duhu: yawan abubuwan da ke cikin halitta, yawanci suna da amfani kuma ba sa lalacewa (amma har yanzu duba yanayin).
– Ja/rawaya: mai yawan sinadarin iron oxide, wanda galibi yana da ruwa sosai, kuma ƙasa mai “oxyidation”. Sau da yawa ana samunsa a tsoffin ƙasa a yankunan zafi.
– Toka/shuɗi-launin toka: yana nuna cewa ƙasar sau da yawa tana cike da ruwa (mai rage yawan ruwa), tana da ƙarancin magudanar ruwa, kuma tana iya fuskantar ambaliyar ruwa.
– Ja-launin toka: canjin ruwan ƙasa; wani lokacin ambaliyar ruwa ce a lokacin damina da kuma bushewa a lokacin rani.
Lura: launi yana shafar danshi, don haka a kula da shi a yanayin danshi da bushewa duk lokacin da zai yiwu.

6. Kimanta tsarin ƙasa da sauƙin noma
Tsarin yana nuna yadda ƙwayoyin ƙasa ke samar da tarawa:
– Tsarin tarkace (granular): yana kama da ƙananan hatsi, waɗanda ake niƙawa cikin sauƙi, suna da iska mai kyau—gabaɗaya suna da kyau ga noma.
– Manyan gungu/manyan gungu: ƙasa tana da yawa, tana da wahalar nomawa, saiwoyinta suna da wahalar shiga.
– Layi mai tauri (kaskon tauri/kaskon noma): ana samunsa a wani zurfin, mai tauri idan ya bushe, yana hana saiwoyi da ruwa.
Gwada gwaji mai sauƙi:
– Tono ƙaramin bayanin martaba, duba idan akwai wasu layuka daban-daban.
– Yi amfani da ƙaramin ƙarfe/screwdriver: idan akwai wani zurfin da ba zato ba tsammani ya yi tauri sosai, wataƙila akwai wani Layer mai ƙarfi.

7. Gwajin magudanar ruwa: gwajin ramin nutsewa
Magudanar ruwa tana tantance ko ƙasa tana sakin ruwa da sauri ko kuma tana riƙe shi na tsawon lokaci.
Mataki:
1. Yi rami mai diamita ± 15–20 cm, zurfin ± 30 cm.
2. A cika ruwa har sama, a bar shi ya jike (wannan ya riga ya jike).
3. Cika kuma, sannan a auna lokacin da zai faɗi.
Tafsirin da aka yi wa kaciya:
– Rushewa cikin sauri: ƙasa mai yashi ko ƙasa mai manyan ramuka; ruwa yana ɓacewa cikin sauƙi, yana buƙatar ingantaccen tsarin ban ruwa/takin zamani.
– Matsakaicin ƙarancin ruwa: gabaɗaya ya dace da tsirrai da yawa.
– Rage ruwa a hankali/ruwa mai tsayi: galibi yumbu, ko kuma tare da Layer mai shiga ruwa; haɗarin rashin iskar oxygen a tushen.

8. Alamomin ƙasa mai sinadarin calcium, acidic, ko gishiri
Wasu nau'ikan ƙasa suna da "halaye na musamman" waɗanda za a iya gano su kawai:
A. Ƙasa ta Calcite
– Halaye: sau da yawa fararen gutsuttsura, ƙasa mai ɗan haske.
– Gwaji: a zuba vinegar a ƙasa; idan ya kumfa, akwai carbonate (lemun tsami).
B. Ƙasa mai tsami
– Halaye na gaba ɗaya: girman wasu shuke-shuke yana raguwa, wasu ciyayi/shrubs suna da rinjaye (ba koyaushe ba).
– Gwaji: yi amfani da takardar pH ko na'urar auna pH mai ɗaukuwa. Ƙasa mai laushi yawanci pH < 5,5. C. Ƙasa mai gishiri/soda - Halaye: farin saman da ke da ƙura, ƙasa tana da wahalar shan ruwa, tsire-tsire suna bayyana "ƙonewa" a gefunan ganye. - Gwaji mai sauƙi: ba a ba da shawarar ɗanɗanon gishiri a harshe ba; ya fi kyau a yi amfani da na'urar auna EC mai ɗaukuwa idan akwai, ko kuma a lura da alamun fili da ɓawon gishiri. --- 9. Haɗa sakamako: Misalin fassarar sauri Don sauƙi, ga misali na haɗa alamomi da yawa: - Mai kauri, ba za a iya rage shi ba, ruwa yana raguwa da sauri → ƙasa mai yashi: ya dace da shuke-shuke masu jure fari, amma yana buƙatar takin zamani akai-akai da ciyawa. - Ganye masu kyau, masu santsi kamar gari, ƙananan ribbons, masu laushi cikin sauƙi → datti mai yawa: mai albarka amma mai saurin yashewa; yana buƙatar murfin ƙasa. - Ribbons masu manne, masu tsayi, sau da yawa laka, fashe lokacin bushewa → da yawa laka: yana riƙe ruwa da kyau, amma yana iya matsewa; yana buƙatar abubuwa na halitta da kulawa mai kyau. --- 10. Kammalawa: Mabuɗin Samun Nasara Gano Ƙasa Gano nau'ikan ƙasa a cikin filin ya fi dacewa ta amfani da haɗin: 1) gwajin laushi (ji da tef), 2) gwajin laka na kwalba, 3) lura da launi, tsari, da magudanar ruwa, da kuma 4) gwajin pH/lime mai sauƙi idan ya cancanta. Da zarar ka yi aiki da hannu kuma ka kwatanta sakamakon da yanayin shuke-shuke da halayen ruwa a cikin filin, to, "jin daɗin ƙasa" ɗinka zai fi dacewa. Idan shawarar ta kasance mai matuƙar muhimmanci - misali, gina harsashi, sake gina ƙasa, ko noman ƙasa mai mahimmanci - ya kamata a tabbatar da sakamakon filin tare da gwaje-gwajen dakin gwaje-gwaje (nazarin laushi, pH, carbon na halitta, NPK, CEC, da gishiri). Ta wannan hanyar, za ku iya fahimtar ƙasa ba kawai daga saman ba, har ma daga halayen zahiri da na sinadarai waɗanda ke ƙayyade yawan amfanin ƙasa da dorewarsa. --- Idan kuna so, zan iya daidaita wannan labarin zuwa takamaiman mahallin (misali, ga manoman shinkafa, gonakin dabino na mai, noman lambu, ko buƙatun ƙasa) kuma ƙara teburin rarrabuwa mai cikakken bayani.
