Umthengisi weDiammonium Phosphate (DAP) eMzantsi Afrika

Yintoni iDiammonium Phosphate (DAP)?

I-Diammonium Phosphate (DAP) sisichumisi esinomxube ovelisa i-18% ye-nitrogen kunye ne-46% ye-phosphorus pentoxide (P₂O₅). Sesinye sezichumisi ze-phosphate ezihlalutywa kakhulu ezikhoyo kwaye sisetyenziswa kakhulu njengesicelo esisisiseko kwimveliso yezityalo ezilinywayo kunye njengezinto eziphambili ze-phosphate eluhlaza kwimveliso ye-NPK edibeneyo. Iigranules ze-DAP ziyanyibilika kumswakama womhlaba ukuze zikhuphe ii-ion ze-ammonium kunye ne-phosphate, ezithathwa ngokukhawuleza ziingcambu zezityalo.

I-DAP vs MAP ekudibaniseni

I-DAP kunye ne-MAP zezona mithombo zimbini ziphambili ze-phosphate ezisetyenziswa ekuxubeni izichumisi. I-DAP inomxholo ophezulu we-nitrogen (18% vs 11%) kunye nomxholo we-P₂O₅ ophantsi kancinci (46% vs 52%) xa kuthelekiswa ne-MAP. Ukukhetha phakathi kwazo kuxhomekeke kwinqanaba le-NPK ekujoliswe kulo, ixabiso ngeyunithi nganye yesondlo, kunye nokuqwalaselwa kwe-pH yomhlaba. I-DAP inempendulo ye-alkaline emhlabeni, nto leyo eyenza ukuba ifaneleke ngakumbi kumhlaba one-asidi, ngelixa impendulo ye-acid ye-MAP ifanele umhlaba one-alkaline. Abaxubi badla ngokusebenzisa zombini ezi mveliso ukuphucula izinga kunye nexabiso.

Ukufumana i-DAP evela kwiTerracore

I-Terracore inika i-DAP e-granular evela kwimithombo yemveliso esele imiselwe kwiingxowa ezingama-25 kg kunye nama-50 kg kunye nobuninzi. Sigcina impahla ukuze sixhase iinkqubo zokuxuba kwaye sinokuhlangabezana neemfuno ezicothayo zonyaka. Amaxwebhu apheleleyo obuchwephesha nokhuseleko anikezelwa kuyo yonke impahla.
