PENGARUH KEDALAMAN MUKA AIR TANAH DAN MULSA ORGANIK TERHADAP SIFAT FISIK DAN KIMIA TANAH GAMBUT PADA PERKEBUNAN KELAPA SAWIT (Elaeis guineensis.Jacq)
Abstract: This researh aimed
to determine the effect of water level and organic mulch on physical and
chemical properties of peatland in palm oil plantation. Research was conducted
for four months which is started on November 2014 to February 2015 at palm oil
plantation of PT. Teguh Karsa Wana Lestari (TKWL) in Buantan Besar village,
sub district Bungaraya, Siak District. By used 8 years old of palm oil plant.
This research used Split Plot Design, consist of 2 factors. The first factor is
the water level as main plot, were: the level of 40-50 cm water, 60-70 cm water
level and 80-90 cm water level. The second factor is giving organic mulch as
sub plot, were: without giving organic mulch, giving palm oil empty fruit bunch
(POEFB), palm frond and Mucuna Bracteata. Therefore obtained 12 combinations of
treatments and 3 replications, so obtained 36 units experiment. Parameters
observed were physical and chemical properties. Data were analyzed by Analysis
of Variance (ANOVA) and were further tested by Least Significant Diference
(LSD) at5 % level. Based on statistical data obtained non significant effects
by water level and organic mulch in physical and chemical properties of
peatland. The result of single factor by organic mulch obtained significant
effects in physical and chemical properties of peatland. The result of single
factor by water level obtained
significant effects in peatland water content parameters.
