Kunstvanding er en vigtig praksis i landbruget, som indeb\u00e6rer kontrolleret tilf\u00f8rsel af vand gennem kunstige systemer for at opfylde afgr\u00f8dernes vandbehov, is\u00e6r i omr\u00e5der med utilstr\u00e6kkelig nedb\u00f8r. Denne metode er afg\u00f8rende for at opretholde den globale f\u00f8devareforsyning for at im\u00f8dekomme behovene hos en voksende befolkning.<\/p>\n\n\n\n

Der anvendes forskellige vandingsteknikker p\u00e5 verdensplan, bl.a:<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n
    \n
  1. Vanding med centralt omdrejningspunkt: Denne metode bruger automatiserede sprinklere, der roterer omkring et centralt omdrejningspunkt og fordeler vand til afgr\u00f8derne i et cirkul\u00e6rt m\u00f8nster. Sprinklerr\u00f8ret eller bommen underst\u00f8ttes over afgr\u00f8den af t\u00e5rne og bev\u00e6ger sig i faste cirkul\u00e6re baner drevet af pneumatiske, mekaniske, hydrauliske eller elektriske midler. Vandet leveres ensartet, og dysest\u00f8rrelserne \u00f8ges gradvist fra omdrejningspunktet til enden af r\u00f8ret. Systemets k\u00f8rehastighed bestemmer den anvendte vanddybde, der typisk d\u00e6kker omkring 130 hektar i et cirkul\u00e6rt omr\u00e5de.<\/li>\n\n\n\n
  2. Drypvanding: Et planlagt vandingssystem, hvor vandet tilf\u00f8res direkte til planternes rodzone ved hj\u00e6lp af applikatorer som f.eks. \u00e5bninger, emittere, por\u00f8se slanger eller perforerede r\u00f8r. Denne metode fungerer ved lavt tryk, og applikatorerne kan placeres p\u00e5 eller under jordoverfladen.<\/li>\n\n\n\n
  3. Furevanding: Denne metode indeb\u00e6rer delvis oversv\u00f8mmelse af overfladen ved at tilf\u00f8re vand i furer eller r\u00e6kker med tilstr\u00e6kkelig kapacitet til at indeholde vandingssystemet. Den bruges ofte til afgr\u00f8der med ren jordbearbejdning.<\/li>\n\n\n\n
  4. Tyngdekraftsvanding: Ved denne type vanding str\u00f8mmer og fordeles vandet ved hj\u00e6lp af tyngdekraften uden behov for pumpning.<\/li>\n\n\n\n
  5. Rotationsvanding: Vanderne f\u00e5r tildelt vandm\u00e6ngder med bestemte intervaller i stedet for et kontinuerligt flow.<\/li>\n\n\n\n
  6. Undervanding: Vand tilf\u00f8res under jordoverfladen, enten ved at h\u00e6ve grundvandsspejlet n\u00e6r rodzonen eller ved hj\u00e6lp af nedgravede perforerede eller por\u00f8se r\u00f8rsystemer, der l\u00f8ber direkte ned i rodzonen.<\/li>\n<\/ol>\n\n\n\n
