Abstract

Acid Sulphate Soil is a kind of soil with high pyrite (FeS2) content. Miss management in land reclamation of acid sulphate soil will cause pyrite oxidation that made the soil becomes very acid. Pyrite oxidation on acid sulphate soil will produce iron oxides such as goethite (α-FeOOH) and hematite (α-Fe2O3). Goethite and hematite have ability to bind the anions and cations in the soilsuch as phosphate which produces a complex surface binuclear with model of Fe-OP(O2)-O-Fe. On acid sulphate land because of its association with soil Fe and its solubility alteration during reduction and oxidation processes of land, P is a limiting factor. More iron oxide in the soil, more P is retentioned. Each m.mol Fe in soil will bind P as much as 0,17 m.mol P.

Abstract

Annisa, et al. Technologies for Mitigating Greenhouse Gas Emissions on Tidal Swamp Land. JLSO 5(2):178-188.Utilization of swamps for agricultural development is a strategic choice in an effort to offset the decrease in productive land in Java due to conversion of land functions from agriculture to non-agriculture. The properties of land in swamplands is a major limiting factor that causes low productivity of swamp land. The development of agriculture in swamplands often has a negative impact on land and environment, due to inappropriate landl management. One of the environmental impacts in swampland development is carbon emissions. Carbon emissions can be reduced through the use of appropriate soil ameliorant and water management within the swamp hydrological area. Both approaches are important not only to mitigate greenhouse gas emissions but also to increase swampland agriculture productivity.

Abstract

A greenhouse experiment was conducted to examine the cumulative methane (CH4) emission in paddy soils and correlation with soil redox potential (Eh), soil pH and plant growth. The experiment was arranged in two factorial randomized block designs with three replications. The first factor was a kind of of organic matter, i.e. without organic matter (T0), combination of 50% of composted straws and 50% composted rush weed (T1), combination of 30% of composted straws and 30% composted rush weed and 40% composted cattle manure (T2) and the second factor was the management of water that was continuously flooded and leaching. The methane emission was measured in South Kalimantan using the chamber and gas chromatogram technique. The results showed methane emission in undisturbed acid sulphate soil ranged from 0.05 to 0.32 mg CH4.m-2.minute-1 during the rice-growing season. The methane emission from the paddy soil were lower when the paddy was drained than when it was flooded. Correlation analysis showed a negative relation between methane emission and soil redox potential (Eh) and soil pH in both water management. The rice plant height and number of buds has positively correlation with methane emission with coeffecient correlation of r=0.84**(P<0.0001) and r=0.64**(P=0.004), respectively.  [How to Cite: Wahida A and A Maas. 2015.

Abstract

Varieties and organic materials have a very important role to the flux of methane (CH4) on paddy cultivation, especially on wetlands. Purpose of this research to determine the amount of methane emissions that released from paddy cultivation in acid sulphate soils with the use of different varieties and paddy straw composting. Acid sulfate soil samples taken Experimental Farm Swampland Agricultural Research Center (BALITTRA), Tanjung Harapan, District Alalak, Barito Kuala, South Kalimantan. This research uses Randomized Complete Design of two factors. The first factor is the use of paddy varieties and the second factor is the use of paddy straw compost. Research shows that there is a very real interaction between the two factors. Treatment varieties Inpara 3 + without paddy straw compost releases CH4 flux most low at 0,030 mg.m-2.day-1, while treatment Inpari 30 + paddy straw compost 5 Mg. ha-1 release most CH4 flux is 0.571 mg. m-2.day-1.

Abstract

As the challenges toward increasing water for irrigation and water scarcity threats become more prevalent, knowledge of crop yield response to water can facilitate the development of irrigation strategies for improving agricultural productivity.  Experiments were conducted to to compare water usage of several irrigation treatment on rice growth performance and productivity and its water use efficiency.  These experiments were conducted using Situbagendit rice variety (115 day length periode), Urea and Tri Super Phospate fertilizer.  Fertilizer dosage follows fertilizer recommendations for rice, i.e : Urea 250 kg/ha, SP-36 100 kg/ha and 100 kg KCl/ha. Irrigation started from land preparation. controll block (deep flooding) was flooded by a water height of 7 cm. Low level continues flow block was flooded by a water height of 3-5 cm. The volume of water used to saturate the soil of the saturated block was estimated. The number of days of non-flooded soil in AWD before irrigation is applied can vary from 1 day to more than 5 days.  The results showed that total volume of water supplied during the rice growing period in the control block was  2,761.91 m3. Total water volume related to the low level continous flow irrigation block was about 1,217.03 and only about  638.98 m3 for the alternate wet and dry irrigation block. Total volume supplied for soil saturation treatment was about 549.74 m3. Regardless the performance of rice crop growth, it?s the most efficient treatment in terms of water use. It only required an amount of water around14-20 % of amount of water consumed by the continuous deep flooding treatment.  The rice yield of deep flooding irrigation treatment was equivalent to 5.6 tons/ha of dry paddy while the yields of low level continuous flow irrigation,alternate wet and dry irrigation and soil saturation treatments reached 5,3 tons/ha,3.36 tons/ha and 2.80 tons/ ha respectively
