Abstract

Coal bottom ash and cattle manure can be used as soil ameliorant. The application of coal bottom ash and cattle manure can improve the soil chemical properties, such as pH and the amounts of available nutrients in soil. The objective of the study was to understand the effect of coal bottom ash and cow manure application on soil chemical properties and heavy metal contents in soil and mustard (Brassica juncea).  A pot experiment was conducted in a greenhouse, including three treatment factors, i.e. age of coal bottom ash (fresh, 4 months and 2 years), dose of coal bottom ash, i.e. 0, 40 and 80 Mg ha-1, and dose of cattle manure, i.e. 0 and 10 Mg ha-1. The results show that the application of coal bottom ash and cattle manure increased the pH and the amounts of total-N, available-P and exchangeable cations (K, Ca and Mg) of the soil. The application of coal bottom ash increased the amounts of Pb, Cd and Co in the soil, but did not increase the amounts of Pb and Co in mustard, while the application of cattle manure increased the amount of Cd both in soil and mustard.  Keywords: Coal bottom ash, cattle manure, heavy metal, mustard, soil ameliorant

Abstract

The use of organic materials aimed at reducing the dependence on inputs such as chemical fertilizers can contribute to sustainability and improving the low N fertilizer efficiency of rice plants in paddy soils.  Therefore, better understanding of N transformation in flooded soils, particularly the microbial transformation of N-organic amendments to plant-available N and gaseous N forms is needed for most efficient use of soil and organic materials N, for determining the potential of denitrification and for aiding in the selection of N management practices for sustainable agriculture.  The experiments were conducted in the laboratory and glasshouse of Soil Department, Faculty of Agriculture, Bogor Agricultural University.  An incubation experiment was conducted in the laboratory at room temperature during 120 d to analyze the mineralization-immobilization patterns in flooded soils amended with rice straw, rice straw composts 4 mo and 8 mo and their combinations with urea.  The first time of soil flooding, mineral N (N-NH4+ and N-NO3-) concentrations in all of the amended soils sharply decreased and those gradually increase since 7 d of incubation.  It might be due to the reduction of N-NO3- to N2O and N2, and immobilization.  This data was consistent with the data of N2O emission derived from pot experiment.  The high emission of N2O was observed at the first time of soil flooding of the amended soils, and the soils added rice straw showed the largest N2O emission than the other treatments. It might be due to the change of soil condition from aerobic to anaerobic condition, and the higher decomposable C as energy source for denitrifyer contained in rice straw.  Regardless the organic materials added to soils, the longer anaerobic condition, nitrification sharply decreased, so that nitrate availability limits denitrifications.decreased, so that nitrate availability limits denitrifications.

Abstract

Coal ash and humic substances can be used as soil ameliorant in the reclamation of formerly mined land. Due to its high pH and nutrients content, coal ash can be used to improve the chemical properties of the soil, such as increasing of pH, and increasing the levels of nutrients availability in the soil. Humic substances may also be used to complement, as they can increase the release of nutrients from the coal ash. Thus, the objective of this study was to assess the influence of coal ash and humic substances on soil chemical characteristics, nutrient absorption, and plant growth. This study was conducted in two locations - in a nursery area, involving two treatment factors: coal ash at different dosages (0, 200, and 400 g polybag-1), and humic material also at varying dosages (0, 0.04, and 0.08 g C polybag-1); and in a post-mining field using similar treatments: coal ash dosage (0, 2.5, and 5.0 kg planting-1 hole) and humic material dosage (0, 0.56, and 1.12 g C planting hole-1). The results showed that coal ash and humic materials significantly increased the soil pH, available P, and exchangeable K, Ca and Mg. Coal ash also contained a number of heavy metals but in quantities that are far below the limits set by both Indonesian Government Regulation and the US Environmental Protection Agency (USEPA). The above soil amelioration effects mean that. applicaton of coal ash and humic substances can significantly increase the growth of Jabon trees in the reclaimed post-mining land.[How to Cite: Ade MO, Sudarsono, Iskandar and DT Suryaningtyas. 2014.

Abstract

Paddy soil has different morphology and pedogenic characteristics compared to dry land, due to the influence of inundation during several months in a year. Puddling and drying that occurs in turns (redox cycle) in paddy soil can lead to the formation of concretions or rusty Fe and Mn. The main purpose of this study was to understand the changing of the morphological and chemical properties as a result of changing of the dry land to paddy soil. Besides, the study also aimed to understand plow pan layer formation in Podsolic, Latosol, Regosol, and Andosol soil type. Results showed that content of soil density (bulk density) of dry land ranged from 0.5  to 1.0, while paddy soil is 0.8 to 1.0 (g cm-3).  Bulk density values in all four types of soils increased after the changing. Observation also demonstrated that severity levels of paddy soil is higher than dry land, especially in the second and third soil layers or under the surface of soils. Acidity of dry land was likely to be higher than paddy soil. There were no significant differences in nutrient such as C-organic, P and N. Meanwhile, using dithionite as solvent, paddy soil has higher Fe, Mn, and Al content than that of dry land, and remain the same when extracted with pyrophosphate and oxalate. From the four types of soil observed,the paddy soil showed formation of plow pan layer. This was shown by the soil severity level higher than the topsoil or other layers. Paddy soil had unique properties due to redox reaction, thereby providing soil discoloration i.e darker due to high solubility of Fe, Mn, and Al.Keywords: Concretion of Fe and Mn, paddy soil, pedogenesis, plow pan layer [How to Cite: Kurniati, Sudarsono and Suwardi. 2016.

Abstract

One of factors that is interasting from Vertisol to be investigated beside the management of the soil fertility was color variations which can vary from gray to brown and brownish red. Exclusive characteristics of Vertisol are shrink swell capacity with clay dominant clay that make agricultural activities in the Jeneponto area less productive. The purpose of this study was to assess the differences of physical and chemical characteristics of black and red Vertisol in Jeneponto R.egency. The research location was based on the difference and overlaying of soil color. Black soils were taken from the village Bontomarannu and Tonrokassi Timur while red soil and overlaying colors of red and black soil were taken from the village Sarroanging. Results showed that one of the chemical characteristic which was very differences between black and red soils were calcium carbonate and base saturation. Generally CaCO3 on black soil was higher (ranged of 13.20-36.73%) than red soil (ranged of 2.21-13.86%). As for overlaying colors of red and black soil were ranged of 2.62-3.88%. The highest base saturation was found in the black soil that was> 100%, red soil between 40-89% and overlaying colors red and black soil between 80-83%. While Fe, Mn and Al concentrations were highest with citrate dithionite bicarbonate extracts followed by oxalate and pyrophosphate extracts. Clay montmorillonite minerals were present in all profiles observed.
