Chowumitsira feteleza wophatikiza
Manyowa ophatikizika, omwe nthawi zambiri amakhala osakaniza a nayitrogeni, phosphorous, ndi potaziyamu (NPK) mankhwala, amatha kuyanika pogwiritsa ntchito njira zosiyanasiyana.Njira yomwe imagwiritsidwa ntchito kwambiri ndi kuyanika ng'oma zozungulira, zomwe zimagwiritsidwanso ntchito ngati feteleza wachilengedwe.
Mu chowumitsira ng'oma yozungulira ya feteleza wapawiri, ma granules onyowa kapena ufa amathiridwa mu ng'oma yowumitsira, yomwe imatenthedwa ndi gasi kapena ma heater amagetsi.Pamene ng'omayo ikuzungulira, zinthuzo zimagwedezeka ndikuwumitsidwa ndi mpweya wotentha womwe umayenda m'ng'omayo.
Njira ina yowumitsa feteleza wapawiri ndiyo kuyanika mopopera mankhwala, komwe kumaphatikizapo kupopera mankhwala osakaniza a fetelezawo m’chipinda chotentha chowumirapo, mmene amaumitsidwa mofulumira ndi mpweya wotentha.Njirayi ndi yabwino kwambiri popanga feteleza wa granular pawiri ndi kukula kwa tinthu.
Ndikofunika kuonetsetsa kuti kuyanika kumayendetsedwa mosamala kuti musawume kwambiri, zomwe zingayambitse kutaya kwa michere ndi kuchepetsa mphamvu ya feteleza.Kuphatikiza apo, mitundu ina ya feteleza wamagulu amakhudzidwa ndi kutentha kwambiri ndipo ingafunike kutentha kocheperako kowuma kuti isagwire bwino ntchito.
