Abstract

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

Abstract

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.

Abstract

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.

Abstract

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.
