微咸沉积物的农业复垦涉及存在于沉积物中的黄铁矿矿物将被氧化并产生不利于植物生长的条件的危险。当沼泽被森林砍伐开垦时，黄铁矿矿物被氧化。挖掘运河和破坏泥炭覆盖层。在南加里曼丹。Banjarese人种植水稻使用的技术适用于土壤，起源于含黄铁矿的沉积物。特别是在可获得用于冲洗有毒材料的非酸性水的情况下。然而.在含有黄铁矿沉积物的地区，农业用地是一个脆弱的系统。即使是多产的稻田也不断受到微妙平衡突然崩溃的威胁。了解班贾雷水稻种植实践对含黄铁矿沉积物地区土壤条件的影响。在实地观察了土地使用和水管理做法。并抽取八个螺旋钻样本作化验分析。结果表明，含黄铁矿沉积物的强烈淋溶导致了一个特定的土壤化学剖面的发展，包括氧化层。一个酸性沉积层。和缩小的视野。本文详细介绍了土壤发育过程和土壤管理问题。
The reclamation of brackish sediments for agriculture involves the danger that pyrite minerals present in the deposits will be oxidized and produce unfavorable conditions for plant growth. Pyrite minerals are oxidized when the swamp is reclaimed by forest cutting. canal excavation and destruction of the peat cover. In South Kalimantan. Banjarese people cultivate rice using a technique adapted to soils that originate from pyrite-containing sediments. especially where non-acidic water for flushing the toxic materials is available. However. the agricultural land in areas with pyrite-containing sediments is a fragile system. Even the productive rice plots are constantly threatened by the sudden collapse of the delicate balance. To understand the effect of the Banjarese rice cultural practice on soil conditions in areas with pyrite-containing sediments. land use and water management practices were observed in the field. and eight auger samples were taken for laboratory analyses. The results show that intensive leaching of the pyrite-containing sediments leads to the development of a specific soil chemical profile comprising an oxidized horizon. an acid accumulating horizon. and a reduced horizon. This paper presents details of soil development processes and soil management problems.
