Abstract
ABSTRACT The toxicity of Al, Fe, and Mn is highly determined by the shape of the metal fractions. Therefore, the specific forms of Al, Fe, and Mn inside the soil are very important to know because they are related to soil fertility. The purpose of this study was to determine the distribution of the Al fraction on the acid soil profile of dry land in Lebak Regency, Banten Province. This research was conducted from April to June 2019 in Maja District, Lebak Regency, Banten. The research was descriptive explorative with intentional sampling for special purposive sampling. The soil was tested with a main parameter using single extraction for Al Fractionation. The results showed that the Al fraction in amorphous form (Al-o) was more dominant than Al in dissolved form (Al-dd) in all horizon layers (0-120 cm). Moreover, the Al fraction in organic amorphous form (Al-p) was also more dominant than Al in the inorganic amorphous form (Al-po) at horizon layer of 0-15 cm, while at horizon laeyer of 15-120 cm the Al-po form was higher than Al-p. Al fraction in the form of organic amorphous had higher bond compared with Al form of organic amorphous in the soil layer of 0-120 cm.

SARAN Perlu dilakukan penelitian lebih lanjut tentang sebaran fraksi logam lain yang terdapat pada lapisan profil tanah masam lahan kering di Kabupaten Lebak Provinsi Banten
Summary
PENDAHULUAN Indonesia merupakan daerah beriklim tropika basah (humid tropics) yang sebagian besar memiliki rejim suhu tanah isohipertemik, dengan curah hujan untuk sebagian wilayah > 2.000 mm/tahun dan musim hujan > 6 bulan. Penelitian ini bertujuan untuk mengetahui sebaran fraksi Al pada profil tanah masam lahan kering di Kabupaten Lebak Provinsi Banten. Profil tanah lahan kering masam di Kecamatan Maja Kabupaten Lebak Total dan K-tersedia mulai dari lapisan Ap ke lapisan Bt3 menunjukkan pola yang sama yaitu terjadi penurunan seiring dengan bertambahnya kedalam tanah.
