Kwezolimo, ukusetshenziswa kukamanyolo kudlala indima ebalulekile ekuqinisekiseni izitshalo ezinempilo nezikhiqizayo. Umanyolo odumile phakathi kwabalimi yi-granular superphosphate (SSP). Le superphosphate empunga empunga iyisici esibalulekile ekwandiseni isivuno sezitshalo kanye nokukhuthaza izindlela ezisimeme zezolimo.
I-granular superphosphate, eyaziwa nangokuthisuper eyodwa i-phosphate, iwumanyolo osebenza kahle kakhulu ngenxa yokugcwala kwayo i-phosphorus, isakhi esibalulekile ekukhuleni kwezitshalo. Le superphosphate empunga empunga yenziwa ngokuphendula i-rock phosphate ne-sulfuric acid ukuze kwakheke ifomu eliyimbudumbudu okulula ukuliphatha nokulifaka emhlabathini. Ifomu le-granular le-superphosphate livumela ukusatshalaliswa nokuthathwa yizitshalo, okuqinisekisa ukuthi imisoco imuncwa kalula.
Enye yezinzuzo eziyinhloko zokusebenzisa umanyolo owodwa we-superphosphate amandla ayo okukhulula ngokushesha i-phosphorus ezitshalweni zakho. Lokhu kubaluleke kakhulu ezigabeni zokuqala zokukhula kwezitshalo, lapho i-phosphorus ibalulekile ekukhuleni kwezimpande kanye nokuqina kwesitshalo sonke. Ngokusebenzisa i-granular superphosphate, abalimi bangaqinisekisa ukuthi izitshalo zabo zithola imisoco edingekayo ngesikhathi esifanele, okuholela ezitshalweni ezinempilo nokwanda kwesivuno.
Ukwengeza, i-superphosphate eyodwa yaziwa ngemiphumela yayo yesikhathi eside emhlabathini. Izakhiwo ezikhishwa kancane ze-phosphorus ku-granular superphosphate ziqinisekisa ukuthi izitshalo zithola izakhi ngesikhathi eside. Lokhu akugcini nje ngokunciphisa imvamisa yokuvundisa kodwa futhi kunciphisa ingozi yokulahlekelwa izakhi, ngaleyo ndlela kukhuthaze ukusimama kwemvelo.
Ngaphezu kwe-phosphorus, i-granular superphosphate iqukethe ne-calcium nesibabule, okuzuzisa impilo yenhlabathi. I-calcium isiza ukugcina i-pH yomhlabathi ibhalansi, kuyilapho isulfure ibalulekile ekuhlanganiseni ama-amino acid namaprotheni ezitshalweni. Ngokufaka lezi zakhi ezibalulekile enhlabathini, i-granular superphosphate inomthelela ekuvundeni komhlaba wonke kanye nokudla kwezitshalo.
Uma kuziwa ekwandiseni isivuno sezitshalo, ukufaka isiceloi-SSP eyimbudumbuduumanyolo ungaba nemiphumela emangalisayo. I-Granular SSP isekela ukukhula kwezitshalo okuqinile ngokunikeza umthombo olinganiselayo futhi ofinyeleleka kalula we-phosphorus, i-calcium nesulfure, okuholela ekwandeni kwesivuno kanye nekhwalithi yezitshalo ethuthukisiwe. Ukwengeza, imiphumela ehlala isikhathi eside ye-SSP eyimbudumbudu inomthelela ezenzweni zezolimo ezisimeme, ukunciphisa isidingo sokuvundisa njalo kanye nokunciphisa umthelela wemvelo.
Sengiphetha, ukusebenzisa umanyolo we-granular superphosphate (SSP) kusiza ukukhulisa isivuno sezitshalo futhi kukhuthaze ezolimo ezisimeme. Ukugcwala kwayo okuphezulu kwe-phosphorus kanye nokuba khona kwe-calcium nesibabule kuyenza ibe ilungele ukukhulisa ukuvunda komhlabathi nokusekela ukukhula kwezitshalo ezinempilo. Ngokufaka i-granular superphosphate emisebenzini yezolimo, abalimi bangaqinisekisa ukusetshenziswa okufanele kwezakhi ezitshalweni zabo, okuholela ekuvuneni okuningi nempilo yenhlabathi yesikhathi eside.
