Organic EprintsDybe jordløsninger i kartoflerChristian Bugge HenriksenauthorDybe jordløsninger øgede udbyttet af salgbare knolde med 14% i et tre-årigt markforsøg, men der var store forskelle mellem årene. I 2001 var udbyttet af salgbare knolde 49% højere mens det totale udbytte blev øget med 5%. I 2002 var der ikke nogen effekt og i 2003 reducerede dybe jordløsninger det totale knoldudbytte med 7%. Uddybende forsøg vil være nødvendige for at undersøge om det er muligt at opnå vedvarende højere salgbare udbytter ved at time de dybe jordløsninger i forhold til vækststadie og nedbørsmængde.
