PENETAPAN KANDUNGAN BAHAN ORGANIK TANAH DI BANJAR BANGAH, DESA BATURITI, KECAMATAN BATURITI, KABUPATEN TABANAN

Abstract

Organic material (BO) is one of the soil components that is sourced from the remaining plants and animals found in the soil. The form of the results of the reform of organic material (vegetable waste) in the soil which is relatively resistant to weathering is humus. This research was carried out in Bangah Banjar, Baturiti Village, Baturiti Subdistrict, Tabanan Regency, Bali Province, with a flat relief condition and on a 1% slope and continuous landuse or vegetation. The way this research works is by taking a handful of soil, placing it on plastic or porcelain, then dripping with 10% H2O2 solution and observing the symptoms that occur, then we observe if there is no foam, it does not contain organic ingredients. little organic (+), there is a lot of foam arising means the content of medium organic material (+ +), and if there arises a lot of foam means high content of organic material (+ + +).  The content of soil organic matter in Banjar Bangah, Baturiti Village, Baturiti District, Tabanan Regency is highest at the 1st horizon and the lowest at the 3rd horizon. This means that the development of plant roots is well located at the 1st horizon while at horizon 3 is not good for plant root development because the content of soil organic material is low. So draenase at the 1st horizon is bad while draenase is at the 3 horizon either due to oxidation or high mineralization.
