Abstract

Liming increases soil fertility through improved soil conditions in acidic soils (Ultisols). This study aimed to determine the effect of limes [CaO; Ca(OH)2; CaCO3 and CaMg(CO3)2 ] on the chemical properties of Ultisols of Limau Manis Padang. Treatments tested in this study application of four types of lime, i.e. A = CaO; B = Ca(OH)2; C = CaCO3; dan D = CaMg(CO3)2. on an Ultisol. A control treatment with no application of lime was also included in this study. After incubation of the soil-lime mixtures for two weeks, the results of the study showed that liming using dolomite [CaMg(CO3)2] was more effective in improving the chemical properties of Ultisols, compared to other types of lime [CaO; Ca(OH)2; CaCO3]. The effect of dolomite on 1*exchangeable Al (1 me Ca 100 g-1) improved chemical properties of an Ultisol from Limau Manis Padang such as pH H2O by 0.35 unit, available P by 1.03 ppm, exchangeable Al by 0.91 cmolc kg-1; exchangeable H by 0.92 cmolc kg-1; CEC by10.49 cmolc kg-1; exchangeable K by 0.03 cmolc kg-1; exchangeable Ca by 0.44 cmolc kg-1 and exchangeable Mg by 1.34 cmol ckg-1, compared to control.

Abstract

The formulation of coal waste (4 million t year-1) and market waste (175.000 t year-1) is a potential development of alternative ameliorant for marginal and swamplands. The purpose of this study was to examine ameliorant formulations from coal and market waste to improve pH, available P, and CEC of Ultisols and Peat. The step I of the study used a completely randomized design with 3 replications, namely A = coal waste (100 g); B = market waste (100 g); C = 1:1 (50 g : 50 g); D = 2:1 (66.7 g 33.3 g-1) and E = 1:2 (33.3 g 66.7g-1). The step II of the study used a completely randomized design with 3 replications in 3 formulations namely: A = best formulation (100 g); B = best formulation + 10% [Ca(OH)2] (10 g 100 g-1) and C = best formulation + 10% [CaMg(CO3)2] (10 g 100 g-1). The step III of the study used a completely randomized design with 3 replications namely: A = 0 t ha-1 (0 g 500 g-1 soil); B = 10 t ha-1 (2.5 g 500 g-1 soil); C = 20 t ha-1 (5.0 g 500 g-1 soil); D = 30 t ha-1 (7.5 g 500 g-1 soil); E = 40 t ha-1 (10.0 g 500 g-1 soil) and F = 50 t ha-1 (12.5 g 500 g-1 soil). The results of the study showed that application of ameliorant formulations from coal and market waste with 10% [CaMg(CO3)2] at 50 t ha-1 increased pH, available P and CEC of Ultisols and peat, respectively by 0.60 units, 2.11 ppm P and 10.83 cmolc kg-1 on Ultisols, and 0.33 units, 2.64 ppm P and 68.86 cmolc kg-1 in peat, compared to control.
