“…The oxidation products are redistributed through the soil profile depending on the water fluxes within the solute transport sub-model. Bronswijk et al (1995) and Van den Bosch et al (1998) used SMASS to evaluate water management strategies for sustainable land use of acid sulfate soil in coastal lowlands in South East Asia where acid sulfate soil is very close to the surface. SMASS was validated by Bronswijk et al (1993Bronswijk et al ( , 1995 and Van den Bosch et al (1998) for their study site conditions and was found to be in good agreement with data measured from the field or in laboratory experiments.…”

The effective management of acid sulfate soils is a major issue for many coastal regions in Australia. Simulations were conducted to evaluate 4 different water management strategies that could be applied to agricultural land on the south coast of New South Wales, Australia, to minimise acid generation from acid sulfate soils. The water management strategies are compared with the existing extensively drained situation which generates and discharges large quantities of acidic pyrite oxidation products. The 4 water management strategies include elevated drain water levels using a weir, 25 mm irrigation on a 7- or 14-day cycle, and elevated drain water levels with irrigation. All of these strategies were designed to minimise the generation of acid by reducing the transport of oxygen to the sulfidic soil. Simulations were conducted for weather and site conditions experienced during a 12-month period starting in July 1997. Model simulations showed that maintenance of elevated drain water levels using a weir in the drain significantly reduced the amount of acid generated by 75% and 57%, at 10 and 90 m distance from the drain, respectively, by comparison with the existing drained state. The addition of 25 mm irrigation on a 14-day cycle to the weir simulation reduced the oxidation of pyrite by a further 1–2%. Application of irrigation only on a 7-day cycle also reduced the acid generated by 89% and 94% at 10 and 90 m distance from the drain, respectively, by comparison with the existing drained state. Irrigation on a 14-day cycle was not as successful in reducing pyrite oxidation as either the 7-day irrigation or weir strategies. Evaluation of the 4 water management options showed that significant improvements can be made with respect to the amount of acid generated by relatively simple and cost-effective land management practices.

“…A significant portion of the stored acidity in these soils occurs in the form of exchangeable and hydrolysable acidic metal cations such as Al and Fe (Dent, 1986;White et al, 1997). Therefore, these soils are a source of environmental degradation worldwide (Bronswijk et al, 1995;Minh et al, 1997;Sundstrom et al, 2002;White et al, 2007).…”

“…If the condition of water management is allowed no improvement then the soil quality will continue to decline and production followed at least until the past 10 years. But if there is improvement of water, pyrite remediation can be accelerated to 3-5 years (Bronswijk, Groenenberg, Ritsema, van Wijk, & Nugroho, 1995).The research aimed to analyze the groundwater levels and to determine the effect of groundwater levels in relation to some soil chemical characters in tidal wetlands P17-5S Mulyasari village Telang Delta II Banyuasin.…”

Agriculture and irrigation policies in the tidal wetlands are often too general, thus at the level of farm units they are often inaccurate in term of quality and quantity. The research purpose was to analyze the groundwater levels and to determine the effect of groundwater levels in relation to some soil chemical characters in tidal wetlands P17-5S Mulyasari village Delta Telang II Banyuasin.Indicators of potential land can be analyzed from parameters of variability of soil acidity, Al and Fe content, organic matter and phosphorus and nitrogen status of the soil. Managed limited area was the smallest unit of water management (tertiary plots). The decision was taken based on the dominant values of the hydro-physical and chemical characters. Input criteria design involved the nature of the soil, land use, and hydrology. The field study and analysis showed dominance in soil physical variability. Around 50% of hydraulic conductivity was classified rapid soil with soil acidity is relatively high, moderate nitrogen, low phosphorus, and moderate potassium. Based on these conditions, cropping pattern applied was rice-corn, rice-water melon, soil fertility can be improved through fertilization of N and P; increasing water gate in the tertiary plots, and the water management aimed to controlled drainage.
