Kale (Ipomea reptans Poir) has high nutrition such as vitamin A, B and C as well as various minerals especially iron which isuseful for human healthand animal. Kale not only can be consume by humans, kale can also be used as forage. Good and quality animal feed must be clean from diseases and heavy metal contamination in it such as Arsenic. Arsenic in the soil can be reduce naturally bu using phytoremeiator plants, one of which is Pteris vittata. The experiment was conducted at the Antirogo Green House, Sumbersari Distric, Jember Regency. Arsenic metal analysis was conducted in BARISTAND, Surabaya and BALITTANAH, Bogor in June 2019 to January 2020. The experimental design used in this study was a Factorial Complete Random Design consisting of 2 factors. The first factor consisted of 4 levels of heavy metal arsenic treatment on kale growth media, namely 0 ppm (D1), 5 ppm (D2), 10 ppm (D3) and 15 ppm (D4). The second factor consists of 2 levels of treatment time of planting ferns that is 1 month (P1) and 2 weeks (P2). Each treatment wa repeated 4 times. The results showed that the interactoin between the tima planting fern and arsenic dose had no significant effect. Absorbtion power of ferns reaches 0,27 ppm to 4,589 ppm highercompared to kale absorbtion reaching 0,006 ppm to 0,155
