Fly-ash (FA) is largely alkaline in nature and contains many essential elements for plant growth along with toxic metals. Therefore, fly-ash is potential to be applied as soil ameliorate that may improve soil properties and plant growth. In this experiment we studied the changes in chemical properties and rice production of acid sulphate soils amended with fly ash. Six different amounts of FA, viz. 0 (100% soil), 5, 10, 20, 40 and 75 tones FA ha-1 were added homogenously to 6 kg of soils in pots of PVC and then chemical properties of acid sulphate soils were observed after a 3-week of incubation. Subsequent of the observation of soil properties, rice was planted onto the pots. Results of study showed that fly-ash application improved soil pH and exchangeable Ca. However, the availability of nitrogen of acid sulphate soils decreased significantly with fly-ash application. The experiment also showed that fly-ash application to soils improved rice growth (height plant, number of tillers, dried-weight root and dried-weight shoot) and rice production. Application 20 tones FA ha-1 resulted in higher rice production than the application 0, 5 and 10 tones FA ha-1, and increasing subsequent the amount of FA application did not significantly increase the rice production. Results of this study demonstrate that low-level fly-ash application resulted in the improvements of soil chemical properties and rice production.Key words: fly-ash application; soil ameliorant; heavy metals; sub-optimal low land.

Wetlands have unique biodiversity and natural phenomena. The climate has recently changed rapidly due to greenhouse gas emissions, especially nitrous oxide from human activities such as paddy rice farming. The purpose of this study is to determine the effect of rice field waste management on the population of nitrogen-fixing bacteria and N2O emissions, and as to determine the shape and closeness of the relationship between the population of nitrogen-fixing bacteria and N2O emissions with different waste management methods. The research method used is a one-factor RGD. Close chamber technique is used for N2O emmisions analysis. The factor tested was the method of managing paddy waste before rice planting with five treatments, namely: A = Rice field waste was slashed and then lifted into the mound after a few days of being returned to the field; B = Rice field waste is carried out management slashed, rolled up, reversed and stretched; C = Rice field waste is slashed, planted with traces and then slashed again after the trace is transferred to land outside the research plot; D = Rice field waste sprayed with herbicide 2 times; E = Rice field waste sprayed with herbicide 1 time and then soil in the tractor. Each treatment was repeated four times so that 20 units of the experiment were obtained. The results showed that the method of rice field waste management carried out had no real effect on N2O emissions and nitrogen-fixing bacteria. N2O emissions not correlate with the activity of nitrogen-fixing bacteria from several methods of rice field waste management carried out

Podzolic soils have various problems including acidity of the soil (pH) and low soil nutrient content. This study aims to determine the effect of guano and dolomite on the availability of P nutrients in podsolik soils, and to determine the best treatment. This study was a pot experiment using a completely randomized design (CRD) with one factor, namely (P1 = Dolomite 2 t ha-1); (P2 = Guano Fertilizer 0,5 t ha-1); (P3 Guano Fertilizer 0.5 t ha-1 and Dolomite 2 t ha-1); (P4 = Guano Fertilizer 1 t ha-1 and Dolomite 2 t ha-1); (P5 Guano Fertilizer 1.5 t ha-1 and Dolomite 2 t ha-1). Each treatment was repeated 4 times, so there were 24 experimental units. The results showed that the application of dolomite and guano fertilizers had an effect on the available-P, pH, Exchangable Ca and Exchangable Al. However, it has no effect on Mg-dd in Podzolic soil. The application of dolomite and guano fertilizer with a dosage of 0.5 t ha-1 guano fertilizer and 2 t ha-1 dolomite was the best result for the availability of P, Exchangable Ca and pH.

Marshes that are affected either directly or indirectly by the ebb and flow of seawater are known as tidal wetlands. The lack of soil nutrients like low pH, N, P, and K, as well as the high solubility of Al and Fe, which can poison plants, is the problem with tidal wetlands. The goal of the study was. to find out how the application of oil palm empty fruit bunch (EFB) ash and water hyacinth compost changed the pH, organic C, N, P, and K levels of the soil in tidal wetlands. The randomized complete design (CRD) method was used in this pot experiment, with two factors: 1) four applications of oil palm EFB ash, and 2) four applications of water hyacinth compost. Oil palm EFB ash had doses of 0 ton.ha-1, 1 ton.ha-1, 1.5 ton.ha-1, and 2 ton.ha-1, while water hyacinth compost had doses of 0 ton.ha-1, 2 ton.ha-1, 3 ton.ha-1, and 4 ton.ha-1, respectively. 32 experimental units were created when 16 treatment combinations were replicated twice. After four weeks of incubation, the soil was submerged in water to a height of 5 cm. The application of oil palm EFB ash and compost made from water hyacinths had significant effects on pH, N-NO3ˉ, available P, and K, but not organic C or N-NH4+. The findings suggest that the application of water hyacinth compost and oil palm EFB ash can raise the pH, organic C, and levels of N, P, K in the soil.

Paddy fields for all of Indonesia are 8.1 million ha, about 43% are in Java and about 57% are outside Java. Paddy fields are part of the wetlands. Paddy fields control the global climate through the gases they produce and have a greenhouse effect. One of the greenhouse gases is methane, therefore the purpose of this study was to determine the effect of rice field waste management on methane emissions and the population of methanogenic microorganisms. The research method used is one-factor Completely Randomized Design (RAL). The factor tested was the method of managing rice waste before planting rice with five treatments namely: A = Rice field waste was slashed and then lifted into the mound after a few days of being returned to the field; B = Rice field waste is carried out management slashed, rolled up, reversed, and stretched; C = Rice field waste is slashed, planted with traces and then slashed again after the trace is transferred to land outside the research plot; D = Rice field waste sprayed with herbicide 2 times; E = Ricefield waste sprayed with herbicide 1 time and then soil in the tractor. Each treatment was repeated four times so 20 units of the experimental. CH4 gas retrieval used the hood method while the microorganism population used the MPN (most probable Number) method. The results showed that the rice field waste management method had an effect on methane emissions and populations of methanogen microorganisms in the planting and vegetative phases, while the generative phase had no effect.

Reclaimed-mining soil (RMS) is characterized by low fertility, acidic pH, and high heavy metal contents. As a result, adding amendments becomes essential to support plant growth. Therefore, this research measured alterations in the characteristics of RMS, plant growth, and metal accumulation in plants with the co-application of coal fly ash (CFA) and empty fruit bunches of oil palm (EFBOP). In the first experiment, various levels of CFA (0, 75, and 150 Mg ha-1) and EFBOP (0, 25, and 50 Mg ha-1) were added to the RMS and then incubated at 70% water holding capacity for 45 days to determine their effect on changes in soil properties. In the second experiment, four treatments: control, CFA, EFBOP, and CFA+EFBOP were tested in the greenhouse to quantify their effects on the growth and metal accumulation of plants. Results of the study showed that the co-application of CFA and EFBOP significantly affected bulk density, pH, mineral nitrogen (NH4+ and NO3-), available phosphorus, and exchangeable Ca and Mg in RMS. CFA application increased exchangeable Al by 82-160%, while EFBOP resulted in a decrease of 24-119%. CEC decreased with CFA application and increased with the use of EFBOP. Plant growth increased with the co-application of CFA and EFBOP. The addition of CFA to soils results in increasing metal contents in plant tissue; however, the presence of EFBOP reduced the concentrations of metal in plant tissue. These results highlight the potential of CFA and EFBOP, which are industrial and agricultural wastes, as valuable soil amendments.
