Isibonakalo esibalulekile sokulima izilimo ezingenisa inzuzo enhlabathini
yakho ukwazi nokuqondisisa izinga le-
pH
noma izinga le-esidi yenhla-
bathi, ezinhlotsheni ezahlukene zenhlabathi, okwenzeka epulazini lakho
ngokuwalinganisa ngesikhathi uhlola inhlabathi yakho noma esikhathini
esingaphambili koku-plana iphrogramu eqinile yokufaka i-
lime
. Uma kune-
simuncwana/esidi noma i-
alkaline
eningi kakhulu inhlabathi ‘ingalungiswa’
ngoku-aplaya ama-
compounds
ahlukene okubalwa kuwo i-
calcitic
noma
i-
dolomitic lime
ngokwe-phrogremu ye-aplikheshini ehlelwe ngokucophe-
lela yesikhathi esifushane nesiphakathi emhlabathini ngamunye.
Uma amandla akho aphezulu nokujula kwenhlabathi kune-esidi ku-
ngenzeka ukuthi uyaphuthelwa ekutholeni isivuno esikhulu sesilimo
eminyakeni enemvula eningi. Ukungeza ithani noma isivuno esikhu-
lu sommbila ngonyaka eminyakeni eminingi kungafinyelela enanini
eliphezulu kokungenayo futhi bese kuba khona ukuqina komnotho
isikhathi eside eminyakeni ezayo. Enanini elingu-R2 500 ithani elilodwa
eminyakeni eyisihlanu lokhu kuzokuba u-R12 500.
Ukuhlehlisa ukuhlaziywa kwamandla enkinga yesimuncwana kanye
noku-implimentwa kwephrogramu ye-
lime
efanele kungabiza kakhulu
ikakhulukazi uma izilimo ezingenisa inzuzo zidimanda izivuno ezinkulu.
Izindleko ngqo zommbila zincike kuthagethi yommbila noma emandleni
enhlabathi ebhekekile kungakhava kusukela ku-R7 000 kuya ku-R10 000
ihektha ngalinye emkhiqizweni wenhlabathi eyo-
mile. Lokhu kusho ukuthi isivuno sika-2,8
t/ha
kuya ku-4
t/h
siyadingeka ukukhave izindleko
ngqo ihektha ngalinye. Njengoba izivuno zalokhu
zizokhokhela izindleko ezinqunyiwe ezifana noku-
khokhela ibhondi, zikhokhele umhlaba oqashiwe,
irenti, ugesi njengokuchaza izindlela ze-akhawunti
namaphrogramu. Kubalulekile ukuhlola amandla
esivuno sakho emininingwaneni yamarekhodi
epulazi. Iningi labalimi lenza isilinganiso esiyihaba
ngesivuno sabo sesikhathi eside ngenkathi benza
i-
gross margin analyisis
