Ka ʻokoʻa ma waena o DAP a me NPK Fertilizer

ʻO ka ʻokoʻa koʻikoʻi ma waena o DAP a me NPK fertilizer ʻo ka DAP fertilizer nopāloloʻoiai ʻo ka mea hoʻomomona NPK aia pū kekahi i ka potassium.

He aha ka DAP Fertilizer?

ʻO nā fertilizers DAP nā kumu o ka nitrogen a me ka phosphorous i hoʻohana nui ʻia i nā kumu mahiʻai.ʻO ka mea nui i loko o kēia mea hoʻomomona ʻo ia ka diammonium phosphate nona ke ʻano kemika (NH4)2HPO4.Eia kekahi, ʻo ka inoa IUPAC o kēia pūhui he diammonium hydrogen phosphate.A ʻo ia ka ammonium phosphate hiki ke hoʻoheheʻe ʻia i ka wai.

Ma ke kaʻina hana o kēia mea hoʻomomona, hoʻopili mākou i ka waikawa phosphoric me ka amonia, ka mea i hana i kahi slurry wela a laila hoʻomaha ʻia, granulated a kānana no ka loaʻa ʻana o ka fertilizer hiki iā mākou ke hoʻohana i ka mahiʻai.Eia kekahi, pono mākou e hoʻomau i ka hopena ma lalo o nā kūlana i hoʻomalu ʻia no ka mea hoʻohana ka hopena i ka sulfuric acid, he mea weliweli ke mālama.No laila, ʻo ka helu nutrient maʻamau o kēia mea momona he 18-46-0.ʻO kēia ke kumu, loaʻa iā ia ka nitrogen a me ka phosphorous i ka ratio o 18:46, akā ʻaʻohe ona potassium.

ʻO ka mea maʻamau, pono mākou ma kahi o 1.5 a 2 tons o ka pōhaku phosphate, 0.4 tons sulfur (S) e hoʻoheheʻe i ka pōhaku, a me 0.2 tons o ka amonia no ka hana ʻana o DAP.Eia kekahi, ʻo ka pH o kēia mea he 7.5 a 8.0.No laila, inā mākou e hoʻohui i kēia mea kanu i ka lepo, hiki iā ia ke hana i kahi pH alkaline a puni nā granules fertilizer e hoʻoheheʻe ʻia i ka wai lepo;no laila e pale ka mea hoʻohana i ka hoʻohui ʻana i ka nui o kēia mea momona.

He aha ka NPK Fertilizer?

ʻO nā fertilizers NPK he ʻekolu mau mea hoʻomomona i pono loa no ka hana mahiʻai.Hoʻohana ʻia kēia mea kanu ma ke ʻano he kumu o ka nitrogen, phosphorus a me ka potassium.No laila, he kumu nui ia o nā meaʻai mua ʻekolu e pono ai ka mea kanu no kona ulu ʻana, ulu a me ka hana pono.Hōʻike pū ka inoa o kēia mea i ka meaʻai hiki ke hāʻawi.

ʻO ka helu NPK ka hui pū ʻana o nā helu e hāʻawi ana i ka ratio ma waena o ka nitrogen, phosphorous a me ka potassium i hāʻawi ʻia e kēia mea hoʻomomona.He hui ia o na helu ekolu, i hookaawaleia e elua kaha kaha.No ka laʻana, hōʻike ka 10-10-10 e hāʻawi ka mea momona i 10% o kēlā me kēia meaʻai.Ma laila, ʻo ka helu mua e pili ana i ka pākēneka o ka nitrogen (N%), ʻo ka helu ʻelua no ka pākēneka phosphorous (ma nā ʻano P2O5%), a ʻo ke kolu no ka pākēneka potassium (K2O%).
