Phosphorus ndi potaziyamu: mawonekedwe, mulingo ndi malo
Ma tubers a mbatata amachotsa pafupifupi 5.8 kg K₂O pa tani, malinga ndi PDA — koma kuchulukitsa zokolola ndi chiwerengero chimenecho kumapereka kuchotsedwa, osati kuchuluka kwa feteleza.

Phosphorus siimayenda bwino m'nthaka, ndipo mizu ya mbatata ndi yochepa. Chifukwa chake, kupezeka kwake m'dera la mizu yaing'ono nthawi zambiri kumakhala kofunikira kuposa kuchuluka kovomerezeka pa hekitala. Bungwe la UK Potash Development Association (PDA) limafotokoza kuti malangizo a phosphate pa mbatata ndi okwera kwambiri kuposa mbewu zomwe zimabzalidwa, pomwe potaziyamu imafunikira kwambiri makamaka panthawi yomera komanso kukula.
Chidule cha PDA cha Marichi 2026 chimapereka mfundo yofotokozera za kuchuluka kwa mbewu: tubers zili ndi pafupifupi 5.8 kg K₂O pa tani. Chifukwa chake 40 t/ha zikutanthauza pafupifupi 232 kg K₂O/ha zomwe zachotsedwa, ndipo 70 t/ha pafupifupi 406 kg. Uku ndi kuwerengera kwa offtake, osati kuchuluka kwa feteleza: gawo la K limachokera kunthaka, ndipo K yayikulu yomwe mbewuyo imasonkhanitsa imaposa zomwe tubers zimachotsa. Kuchuluka sikungapezeke pongochulukitsa zokolola ndi coefficient.
Masiku a sabata. Tulutsani kulembetsa mutangodina kamodzi.
Kuwerengera pogwiritsa ntchito PDA coefficient: 5.8 kg K₂O pa tani imodzi ya tubers
K₂O imachotsedwa ndi mizu, kg/ha. Izi ndi zotsalira, osati kuchuluka kwa feteleza.
Magwero a potaziyamu nawonso ndi ofunika. Ku Ireland, Teagasc ikugogomezera kuti pazifukwa zina zopangira, mitundu ya sulphate imatha kusunga zinthu zouma bwino kuposa chloride; koma potaziyamu wochuluka wa mtundu uliwonse ukhozanso kuchepetsa zinthu zouma. Mtundu wa chloride suletsedwa kwenikweni: kusankha kumadalira nthawi, nthaka ndi zofunikira za tubers.
Jiografia ndi kugwiritsa ntchito kothandiza
Malangizo a ku Britain ndi ku Ireland amagwira ntchito ngati njira yowerengera nyengo yozizira; minda ya K yochepa ku Eastern Europe imafunika kuyesedwa kwawo. Pa mchenga wothiriridwa ku Idaho, chisamaliro chapadera chimapita ku gawo la K yosonkhanitsa ndi kuyang'anira.
Zolemba za m'madera
- Russia & Central Asia (Kazakhstan, Uzbekistan): Dothi la mchenga lokhala ndi K yochepa m'chigawo chapakati cha Russia ndi sierozems zothiriridwa ku Central Asia zimafunikira kudziwa kwawo kwa K; chiwerengero cha PDA chochotsera chimangothandiza pamlingo woyenera.
- Latin America (Brazil, mayiko a Andes): Dothi la m'madera otentha nthawi zambiri limasunga phosphorous, kotero kuyika pafupi ndi mzere ndikofunikira kwambiri kuposa nthaka yofunda.
- Africa (Kenya, Nigeria, Zimbabwe, Zambia): P ndi vuto lofala kwambiri pa nthaka yokhala ndi asidi; K inali yokwanira kwa nthawi yayitali koma deta ya ku Kenya ikuwonetsa kuchepa kwa nthaka m'minda yomwe yalimidwa kwambiri.
- Kum'mwera chakum'mawa kwa Asia (Vietnam, Thailand, Philippines): Pa nthaka yamapiri yonyowa, K imatha kutayika ndi mvula yamphamvu; K yogawidwa pamene chizindikiro ndi nthaka zimalola.
Malangizo a zaulimi apa ndi njira yodziwika bwino; gwirizanani mitengo ndi nthawi ndi katswiri wanu wa zaulimi.
Zinthu zogwirira ntchito limodzi: Uralchem zinthu — kusankha kokhazikika
NPKS 8:20:30:3Pakugwiritsa ntchito maziko kapena mikanda, Uralchem's granular NPKS 8:20:30:3 can be considered: according to the catalogue it contains 8% N (ammonium form), 20% P₂O₅, 30% K₂O and 3% S. The rate is calculated from soil analysis and the balance of all nutrient sources; a brand name does not replace a field calculation. In a band at planting, keep the fertilizer away from the seed tuber: a high-K granular grade raises the salt (and chloride) load near the sprout.
Zithunzi za malonda: Uralchem.
Kodi Uralchem zinthu zoperekedwa: Russia ndi CIS, Latin America, Africa (kudzera mwa wogawa wake United Fertilizer Company Limited) ndi South-East Asia, komwe kampaniyo ikupanga kugawa ku Vietnam, Thailand ndi Philippines. Kupezeka kwa magiredi enaake kumasiyana malinga ndi dziko - funsani kwa wogawa wakomweko.
Palibe malangizo okhudza mitengo - funsani katswiri wa zaulimi.
