Ihlobo yisikhathi sokushisa kwelanga, ukufudumala nokukhula kwezitshalo eziningi.Nokho, lokhu kukhula kudinga ukunikezwa okwanele kwemisoco ukuze kuthuthuke kahle.Ukuvundisa kudlala indima ebalulekile ekuletheni lezi zakhi ezitshalweni.Amanothi okukhulelwa ehlobo abalulekile kubo bobabili abalimi abanolwazi nabasaqalayo ukuhlakulela ingadi eningi.
Uma kuziwa ekuvundiseni ehlobo, isikhathi siyikho konke.Kubalulekile ukwazi ukuthi ungangeza nini imisoco emhlabathini ukuze uqinisekise ukuthi izitshalo zithola izinzuzo eziphezulu.Ukwengeza kusenesikhathi kungaholela ekulahlekelweni kwemisoco, kuyilapho ukungezwa sekwephuzile kungakhinyabeza ukukhula, futhi, kwezinye izimo, kulimaze izimpande zesitshalo.Ngakho-ke, kungcono ukuvundisa izitshalo ngaphambi nje kokuqala kwehlobo.Lokhu kuqinisekisa ukuthi izitshalo zizoba nemisoco edingekayo futhi zizoba nezimpande eziqinile.Ngale ndlela, izitshalo zizothola ukugeleza kwemvula encane, okwenza inqubo yokuvundisa iphumelele nakakhulu.
Esinye isici esibalulekile sokuvundisa ehlobo ukukhetha uhlobo olufanele lokudla kwezitshalo.Ngokuvamile, uhlobo lukamanyolo olusetshenziswa ngezinye izinkathi zonyaka lungase lungafaneleki ehlobo.Izitshalo zidinga umsoco owengeziwe ehlobo ngenxa yokukhula okukhulayo nokulahlekelwa kwamanzi, okuvame ukunikezwa ngokufaka umanyolo kabili ngenyanga.Abalimi kufanele bakhethe umanyolo one-nitrogen encane ne-phosphorus kanye ne-potassium ne-calcium eyengeziwe, esiza ekukhuleni kwezitshalo nasekuthuthukisweni kwezimpande.Kunezinhlobonhlobo zomanyolo ongakhetha kuzo izitshalo, okuhlanganisa umquba, umquba, nomanyolo wamakhemikhali.Kodwa-ke, umanyolo wamakhemikhali kufanele usetshenziswe ngokuqapha, njengoba ukusetshenziswa ngokweqile kungaholela ekushiseni kukamanyolo kanye nokulimala kwemvelo.
Sengiphetha, ukuvundisa ehlobo kudlala indima ebalulekile ekukhuleni kwezitshalo, futhi kubalulekile ukuvundisa izitshalo ngesikhathi esifanele ngohlobo olufanele lokudla.Abalimi kumele babhale amanothi mayelana nokuvundiswa ehlobo ukuze kuqinisekiswe ingadi eningi futhi enempilo.Kubalulekile ukulandela indlela engaguquguquki yokuvundisa ngokufaka umanyolo ngaphambi nje kokuba kuqale inkathi yasehlobo futhi uqhubeke nenqubo kabili ngenyanga.Ukukhetha uhlobo olufanele lomanyolo onenitrogen encane ne-phosphorus ne-potassium ne-calcium eningi kubalulekile ngokufanayo.Ngokugcina la maphuzu engqondweni, umlimi angahlakulela ingadi echumayo ehlobo.
