Ukubaluleka Kwe-Single Super Phosphate Kwezolimo Zanamuhla

Yethula:

Kwezolimo zesimanje, isidingo sokwandisa umkhiqizo kanye nezinqubo zokulima ezisimeme sesibaluleke kakhulu.Ukusetshenziswa kukamanyolo kudlala indima ebalulekile njengoba abalimi nososayensi bezama ukulinganisa phakathi kokukhulisa isivuno sezitshalo nokuvikela imvelo.Phakathi kwezinhlobo ezahlukene zomanyolo,super eyodwa i-phosphateI-SSP igqama njengengxenye ebalulekile ekwenzeni ngcono ukuvunda komhlabathi nokuqinisekisa isivuno esihle.Kule bhulogi, sizocubungula ukubaluleka kwe-SSP kwezolimo zesimanje kanye negalelo layo ezinhlelweni zokulima ezisimeme.

Funda ngama-superphosphates angawodwa:

I-superphosphate eyodwa(SSP) umanyolo ocebile nge-phosphorus oqukethe imisoco emibili ebalulekile ekukhuleni kwezitshalo: i-phosphorus nesulfure.Lo manyolo utholakala ngokuphendula i-sulfuric acid (H2SO4) nedwala le-phosphate ukuze kwakhiwe i-monocalcium phosphate.Ngokufaka i-superphosphate ezinhlelweni zezolimo, abalimi bangakwazi ukuqinisa inhlabathi ngezakhi ezidingekayo izitshalo ukuze zikhule.

Thuthukisa ukuvunda komhlabathi:

I-Phosphorus iyisici esibalulekile sayo yonke into ephilayo futhi ukutholakala kwayo enhlabathini kuthinta ngqo ukukhiqizwa kwezitshalo.I-SSP iwumthombo othembekile we-phosphorus, oqinisekisa ukuthi izitshalo zithola i-phosphorus eyanele ngesikhathi sokukhula.I-Phosphorus idlala indima ebalulekile ekuthuthukiseni izimpande, ukudluliswa kwamandla kanye nokuqhakaza.Ngokukhuthaza lezi zinqubo ezibalulekile, i-SSP ivula indlela yezitshalo ezinempilo kanye nesivuno esithuthukisiwe sezitshalo.

I-Equilibrium PH:

Enye inzuzo ye-SSP yikhono layo lokubhekana nezinkinga ze-acidity yenhlabathi.I-acidity eyeqile ikhinyabeza ukumuncwa kwezakhi, kuvimbela ukukhula kwezitshalo.Kodwa-ke, okuqukethwe kwe-calcium ku-superphosphate kwenza i-pH yomhlabathi ingabi namandla, ikwenze kube lula ukumuncwa kwezakhi.Ngaphezu kwalokho, ukwengeza isulfure kusiza ukuthuthukisa ukwakheka kwenhlabathi, okuvumela izimpande ukuthi zingene kalula futhi zifinyelele imisoco eyengeziwe.

Izinqubo Zezolimo Eziqhubekayo:

Ukusetshenziswa kwe-SSP kuhambisana nezinqubo zezolimo ezisimeme.Ngokwenza ngcono ukuvunda kwenhlabathi nokusebenzisa kahle izakhi, abalimi banganciphisa isidingo somanyolo oweqile, ngaleyo ndlela banciphise imithelela engaba khona emvelweni.Ukwengeza, ukuncibilika kwamanzi okuphansi kwe-superphosphate kusho ukuthi i-phosphorus ingahlala isikhathi eside enhlabathini, inciphisa ingozi yokugeleza nokungcoliswa kwamanzi.

Izinzuzo zomnotho:

Ngaphezu kwezinzuzo zemvelo, i-SSP iletha izinzuzo zezomnotho kubalimi.Ngenxa yokuqukethwe okuphezulu kwezakhi kanye nezakhiwo zokukhululwa kancane, i-SSP iqinisekisa ukusebenza kahle kwesikhathi eside, inciphisa imvamisa yokuvundisa.Lesi sici asisizi nje kuphela ukwehlisa izindleko, siphinde songa isikhathi esibalulekile nomsebenzi.Ukwengeza, ukwanda kwezivuno zezitshalo kusetshenziswa i-superphosphate kungakhuphula kakhulu inzuzo yabalimi futhi kube nomthelela ekuthuthukisweni kwezomnotho jikelele kwemiphakathi yabalimi.

Ekuphetheni:

Sengiphetha, i-SSP idlala indima ebalulekile kwezolimo zesimanje, ibambe iqhaza ekulimeni okusimeme kanye nokwandisa ukukhiqizwa kwezitshalo.Ngokwenza ngcono ukuvunda komhlabathi, ukwenza i-pH ibe lula, ukukhuthaza ukutholwa kwezakhi kanye nokunciphisa ukuthembela kumanyolo wamakhemikhali, i-SSP izuzisa kokubili imvelo kanye nenhlalakahle yezomnotho yabalimi.Ukusebenzisa lo manyolo obalulekile kubonakale kusemqoka ekuqinisekiseni ikusasa elisimeme lezolimo, njengoba ukukhiqiza nokunakekela imvelo kuhambisana.
