      Abstract
      Penambahan amelioran Fe³ dan fosfat alam yang mengandung kation Fe tinggi dapat mengurangi pengaruh meracun asam-asam organik, meningkatkan stabilitas gambut melalui pembentukan senyawa komplek dan mengurangi emisi karbon. Dalam penelitian ini digunakan tanah gambut dari Riau dengan tingkat kematangan hemik, fosfat alam sebagai sumber P adalah fosfat alam Gresik (kandungan Fe 5,10%), Christmas (kandungan Fe 2,4%), dan Huinan China (kandungan Fe 0,77%), dan sebagai bahan amelioran digunakan FeCh.6H2O.
       
      The addition of ameliorant Fe³ and rock phosphates containing high Fe cation can reduce effect of toxic organic acids, increase peat stability through formation of complex compounds and reduce carbon emission. The research was conducted in laboratory and green house of the Department of Soil Science, Faculty of Agriculture, IPB. Peat samples with hemic degree of decomposition were taken from Riau. Rock phosphates in this research (P and Fe sources) were the rock phosphates of PT. Petrokimia Gresik (the content of Fe was 5,10%), Christmas Island phosphates (the content of Fe was 2,40%) and Huinan China (the content of Fe was 0,77%). FeCl2.6H₂O was used as the other Fe* source.
