“…Since the accumulation of toxic substances such as aluminum, shortage of nutrients such as phosphorus, magnesium and calcium, decrease in the microbial activity and activation of "soil blight" become serious constraints on crop production, actual acid sulfate soils are recognized as global problem soils. Potential and actual acid sulfate soils are estimated to cover 12-15 million hectares in the world, and occur extensively, particularly in the tropical countries of South East Asia, such as in Thailand, Vietnam, Malaysia and Indonesia (Takai et al 1989;Golez 1995;Mathew et al 2001;Gosavi et al 2004;Shamshuddin et al 2004).…”

Most of the soils in the upland areas of Peninsular Malaysia are classified as Ultisols. Oil palm production on these soils is usually limited by their inherent low soil productivity.However, the crop is cultivated successfully on most of the soils following right soil management practices. A study was conducted in Bera, Malaysia to determine the characteristics and fertility of an Ultisol cropped to oil palm for many years continuously. In this study, the soil in the plantation was sampled, analyzed and classified. The soil under study was formed under tropical environment with udic moisture regime on fine-grained sedimentary rocks mixed with tuffs of Permian age. Due to very long exposure to the condition of high temperature and high rainfall throughout its development, the soil in the area was reddish in color, clayey, deep and highly weathered. The study found that the clay fraction of the soil was dominated by kaolinite, hematite, goethite and gibbsite; hence, the CEC and basic cations were low. Besides, soil reaction was acidic in nature with soil pH slightly below 5, but the exchangeable Al was more than 1 cmol c /kg soil. However, it was believed that these inherent characteristics were not expected to significantly affect the production of oil palm grown on the soil. With proper agronomic practices, the area can be utilized for oil palm production sustainably.

“…This pedogenic pyrite can easily be oxidized on exposure to the air, releasing sulfuric acid and Al and/or Fe into the soil environment where, under anaerobic conditions, these metals mostly exist as Al 3+ and Fe 2+ , respectively. In the end, a yellowish mineral called jarosite (KFe3(SO)2(OH)6) is formed [2]. Based on the physicochemical properties, as defined by the Soil Survey Staff, most of the acid sulfate soils in the ASEAN region used for agriculture can be classified as sulfaquepts [3].…”

Applying Limestone or Basalt in Combination with Bio-Fertilizer to Sustain Rice Production on an Acid Sulfate Soil in Malaysia

et al. 2016

Abstract:A study was conducted to determine the efficacy of applying ground magnesium limestone (GML) or ground basalt in combination with bio-fertilizer to sustain rice production on an acid sulfate soil in Malaysia. Soils from Kelantan Plains, Malaysia, were treated with GML, ground basalt, bio-fertilizer, GML + bio-fertilizer, and ground basalt + bio-fertilizer (4 t¤ ha ¡1 each). Results showed that soil fertility was improved by applying the soil amendments. GML and basalt contain some Zn and Cu; thus, application of these amendments would increase their contents in the soil needed for the healthy growth of rice. Basalt applied in combination with bio-fertilizer appeared to be the best agronomic option to improve the fertility of acid sulfate soils for sustainable rice production in the long run. In addition to increasing Ca, Mg, Zn, and Cu reserves in the soil, water pH increased and precipitated Al 3+ and/or Fe 2+ . Ground basalt is cheaper than GML, but basalt dissolution in the acidic soil was slow. As such, its ameliorative effects could only be seen significantly from the second season onwards. The specially-formulated bio-fertilizer for alleviating the infertility of acid sulfate soil could also enhance rice growth. The use of the bio-fertilizer fortified with N 2 -fixing bacteria is a green technology that would help reduce NO 3 ¡ and/or NO 2 ¡ pollution and reduce the cost of rice production. The phosphate-solubilizing bacteria (PSB) present in the bio-fertilizer not only increased the available P, but also helped release organic acids that would inactivate Al 3+ and/or Fe 2+ via the process of chelation.
