Umba obalulekileyo wokulima izityalo zorhwebo emhlabeni wakho
kukwazi nokuqonda ukuba lithini iqondo le-pH okanye lobuasidi bemihla-
ba, kwiintlobo ngeentlobo zemihlaba, ezikwifama yakho, ngokulilinganisa
xa usenza uvavanyo lwemihlaba okanye phambi kokwenza ucwangciselo
lwenkqubo yokukalika ehlanganiselweyo. Ukuba umhlaba uasidi okanye
ualkaline ngokugqithiseleyo, ‘usenokulungiswa’ ngokufaka imidibaniso
eyahluka-hlukileyo kuqukwa ikalika ecalcitic okanye edolomitic kwinkqu-
bo yokulungisa yethuba elifutshane, eliphakathi nelide ecwangciselwe
ngokuqaphela kwintsimi nganye.
Ukuba imihlaba yakho enesakhono esiphezulu neyona inzulu iasidi kakhulu
usenokukuphosa ukufumana izivuno ezizezona ziphezulu kwiminyaka ye-
mvula eyiyona ifanelekileyo. Ukongeza itoni okanye ngaphezulu yesivuno
sombona kwiminyaka emininzi kungakhokelela ekwandeni okukhulu kwe-
ngeniso ukuze kubekho uzinzo kuqoqosho kwiminyaka ezayo. Kwixabiso
elingange-R2 500 ngetoni kwiminyaka emihlanu kungafumaneka i-R12 500.
Ukubambezela uhlalutyo lwengxaki enokuba ikhona yeasidi egqi-
thiseleyo nempumezo yenkqubo efanelekileyo necwangciselweyo yoku-
kalika kusenokuba neendleko eziphezulu kakhulu ngakumbi xa isityalo
esinenzuzo encomekayo sidinga izivuno eziphezulu. Iindleko ezingqali-
leyo zombona zixhomekeke kumgqaliselo wesivuno okanye kwisakhono
semihlaba ephantsi kwengqalelo futhi zinokufikelela kuluhlu olususela
kuma-R7 000 ukuya kuma-R10 000 ngehektare
malunga nokulima emhlabeni owomileyo. Oku
kuthetha ukuba isivuno seetoni ezi-2,8 ngehek-
tare nganye ukuya kwiitoni ezi-4 ngehektare
esifunekayo ukuhlangabeza iindleko ezingqali-
leyo ngehektare nganye. Naziphi izivuno ezi-
ngaphezu koko ziya kuya kwiindleko zakho
ezisisigxina ezifana nokubuyisa imali yesibophe-
lelo sentlawulo yendlu, iintlawulo zokuqesha
umhlaba, irenti, umbane njengoko kuchazwe
ngokwemigaqo yakho yobalo-mali neenkqubo.
Kubalulekile ukuhlola isakhono sesivuno sakho
ngaphandle kweengxelo ezineenkcukacha zafa-
ma. Abalimi abaninzi banoqikelelo abalubaxayo
lwezivuno zabo zenene xa besenza uhlalutyo
lwabo lomda wesivuno esipheleleyo.
