PEMANFAATAN BEBERAPA JENIS DAN DOSIS LIMBAH KELAPA SAWIT (Elaeis guinensis Jacq) TERHADAP PERUBAHAN PH, N, P, K TANAH PODSOLIK MERAH KUNING (PMK)
Abstract: This research has
been conducted on January until February 2015 at Agrostologi laboratory,
industrial feed and soil science laboratory, in State Islamic University Sultan
Syarif Kasim Riau. The purposed of the research was to determine the effect of
bunch ash, boiler ash, and palm oil sludge with different doses of the
red-yellow podsolic fertility. The research used random sampling method that
consist of (1). Red-yellow podzolic soil with a bunch ash as much as 5 ton/ha
(25 g), 10 ton/ha (50 g), 15 ton/ha (75 g). (2). Red-yellow podzolic soil with
boiler ash as much as 5 ton/ha (25 g), 10 ton/ha (75 g), 15 ton/ha (75 g). (3).
Red-yellow podzolic soil with sludge as much as 5 ton/ha (25 g), 10 ton/ha (50
g), 15 ton/ha (75 g). Total of treatment were 20 pollybag. Parameters
observation consist of value pH H2O, N, P, K. The results showed that bunch ash
doses of 15 ton/ha was the best material to improvement of soil chemical
properties red-yellow podzolic (pH H2O, P and K), subsequently followed by
boiler ash, but a decline N of giving bunch ash and boiler ash while sludge
doses 15 ton/ha is the best material to improvement of soil chemical properties
N.
