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 yomhlabathi. 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 ukunciphisa izindleko, siphinde songa isikhathi esibalulekile nomsebenzi. Ukwengeza, ukwanda kwezivuno zezitshalo kusetshenziswa i-superphosphate kungakhuphula kakhulu inzuzo yabalimi futhi kube nomthelela ekuthuthukisweni komnotho 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.
