AbstrakTujuan penelitian ini adalah untuk mempelajari pengaruh penambahan kompos purun tikus dan fosfat alam terhadap reaksi tanah dan erapan fosfat tanah gambut. Rancangan yang digunakan adalah rancangan acak lengkap dengan dua factor dan tiga ulangan. Faktor pertama adalah kompos purun tikus (0, 10 dan 20 ton/ha) dan factor kedua adalah fosfat alam (0, 45, 90 dan 135 kg/ha). Hasil penelitian menunjukkan penambahan kompos purun tikus meningkatkan konstanta Langmuir dan jumlah tapak erapan fosfat tanah gambut, sebaliknya fosfat alam menurunkan jumlah tapak erapan fosfat. Interaksi kompos purun tikus dan fosfat alam nyata menurunkan kemasaman tanah.Kata Kunci : Erapan P, Fosfat Alam, Gambut, PurunAbstractThe objective of this research are to study the effect of Eleocharis compost and rock phosphate on soil reaction and sorption of phosphate onto peat soils. The research was conducted in completely randomized design with two factor and three replicates. First factor are level of Eleocharis compost (0, 10 and 20 ton/ha) and second factor are level of rock phosphate (0, 45, 90 and 135 ton/ha). The result showed that application of Eleocharis compost increased Langmuir constant and amount of phosphate absorbents on peat soils, while application of rock phosphate decreased amount of phosphate absorbents. Interaction between Eleocharis compost and rock phosphate have significantly effect to decreased soil acidity.Keywords : P-sorption, Rock Phosphate, Peat, Eleocharis Grass
