“…Hal ini menunjukkan bahwa pemberian dolomit saja sudah dapat meningkakan pH dan menurunkan Al dd di tanah masam sehingga meningkatkan kation-kation basa tanah walaupun tanpa pupuk anoganik dan pupuk kandang. Hal yang sama juga ditemukan oleh Agustina et al (2010), Verde et al (2013), dan Muindi et al (2015). Kapur yang larut dalam tanah akan melepas ion Ca 2+ dan Mg 2+ dan menggantikan ion H + dan Al 3+ (Kisinyo, 2016).…”

ABSTRACT<br /><br />The imbalanced supply-demand of soybean is the main reason of soybean import in Indonesia. One of the efforts to increase of soybean production was expanding the planting area to acid soil with a low pH, high content of Aluminum, and low nutrient availability, through giving ameliorant, such as liming organic materials, and mineral fertilization.This study was aimed to obtain the best combination of fertilizer and amelioran for soybean production in acid soil. The study was conducted in experimental station of Tenjo, Bogor from November 2015 to March 2016. The experiment used a randomized complete block design with two factors. The first factor was combinations of fertilizer and amelioran, i.e., P0 (without fertilization); P1 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) ha-1}; P2 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 1,250 kg of manure ha-1}; P3 {50 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P4 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P5 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) ha-1}; P6 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomites 1 x Aldd (3,220 kg) ha-1}. The second factor was soybean varieties of Tanggamus and Anjasmoro. The results showed that application of 75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) produced the highest productivity (2.91 ton ha-1), but it was not different from reducing the dose of dolomite into ¼ x Aldd (805 kg) with the addition of 2,500 kg of manure.<br /><br />Keywords: Al saturation, chemical properties of soil, nutrient uptake, produktivity, soil amelioran

“…Lime enhanced the availability of more P by the Ca 2+ contained in lime displacing H + , thus resulting in a reduction in acidity implying less solubility of Al 3+ that had fixed P. This is supported by Muindi et al (2015) who found out that application of lime results in increase of soil pH and extractable P and decrease of P adsorption levels leading to replacement of hydrogen ions on the soil surface by Ca 2+ . It was found out in this study that, limed treatments of Tithonia and filter mud having 39 kg P ha -1 significantly raised the available P in both sites.…”

“…Phosphorus sorption by soils is influenced by soil pH, ionic species in the soil solution, clay mineralogy, organic matter content, free iron and aluminium, soil calcium carbonate, temperature and time of equilibration (contact) among other factors [13,98,99,48,100].…”

“…The dominant P ion species present in acid soils are H 2 PO 4 and PO 4 3in alkaline soils [51,101]. Adsorption of phosphorus by iron and aluminium oxides also declines with increasing pH [13,48,100] due to reduced solubility of Fe and Al ions. At lower pH, adsorption results from the reaction with iron and aluminium (reaction equation xiv) and their hydrous oxides while above pH 7.0, ions of calcium, and magnesium and their carbonates cause P precipitation (reaction equation xv) [13,48,102].…”

Phosphorus is the second most important crop nutrient after Nitrogen. It is an essential macronutrient that plays important role in all crop biochemical processes such as photosynthesis, respiration, energy storage, transfer, cell division, cell enlargement and nitrogen fixation. It is also important in seed germination, seedling establishment, root, shoot, flower and seed development. Despite its importance in crop nutrition, availability of the nutrient in soils for plant uptake is limited by several soil factors. The factors include: soil pH levels, clay mineralogy, organic matter, free iron and aluminium, calcium carbonate, soil temperatures and availability of other nutrients among other factors. Availability of phosphorus for plant uptake can be managed by adoption of practices such as liming acidic soils, application of organic amendments in both alkaline and acidic soils, tillage practices and regulation of time and method of P fertilizer application.
