Abstract

The Effects of Various Water Table Depths on CO2 Emission at Oil Palm Plantation on West Aceh Peat (EP  Handayani, M van Noordwijk, K Idris,  S Sabiham and S Djuniwati):  Changes in the depth of water table influenced carbon cycling in peatlands, and affected the sources and sinks of carbon dioxide.  The effects of depth of water tables in oil palm plantations on the emission of CO2 were studied. CO2 emissions of peatland were measured in Meulaboh, West Aceh using cylindrical chambers and  air samples from the chambers were analyzed by gas chromatography. Five-point transects perpendicular to drainage canals provided variation in the depth of water tables for the samples. Data from oil palm fields were compared to data from an adjacent swamp forest. The data confirmed that  the increasing depth of water table was accompanied by the increasing in microbial activity that was measured by CO2 emission.  The CO2 emissions from chambers with additional root zones were higher than from bulk soil chambers between one to four times.

Abstract

The practices of tin mining which removing all layers of soil on deposits of minerals caused the seriously environmental problems, i.e degradation of physical and chemical soil, disappearance of vegetation, flora and fauna in ecosystems that changed the microclimate. In the tailings area of tin mining have unstable structure, the content of organic matter is very low, so it is vulnerable to land slides and erosion. The characteristic of tailing area that very acid, low nutrient availability, low water storage and high soil temperature are constraints in the conservation and improvement this area. The aim of this research was found conservation technology to improve the properties of  soil on Tin mining land due to human activities that cause environmental damage both micro and macro so determination of plant species and specific location technology can be done based on characterization and potential evaluation soil resources. Annual crop cultivation and cultivation of legume cover crop (Mucuna sp., Long-lived, Calopogonium sp., Peuraria javanica) and management of top soil and organic matter are a must, in addition to improve soil structure, maintaining soil moisture, as well as to reduce the loss nutrients, as in  textured rough soil (sandy) nutrients in soil are easily washed.Keywords: Characteristic soil, improvement, tailing area, tin mining

Abstract

The cultivation of Red Onions (Allium ascalonicum, L.) in paddy fields needs to be investigated further because paddy fields have constraints on the soil physical and chemical properties, such as soil structure, drainage, pH, and nutrient availability. The application of husk charcoal and K fertilizer is expected to increase the productivity of Red Onions, so it is necessary to study the appropriate dose. The research aimed to determine the effect of the interaction between the application of husk charcoal and KCl fertilizer and the influence of each factor on the growth and yield of Red Onions. The results showed that rice husk charcoal treatment at a dose of 20 Mg ha-1 was effective in increasing the growth and yield of Red Onions compared to rice husk charcoal at a dose of 10 Mg ha-1 and 0 Mg ha-1 (control), as evidenced by the variable shallot plant height, number of leaves, number of tubers per clump, wet tuber weight per clump, and tuber dry weight per clump. KCl fertilizer treatments at doses of 100 kg ha-1, 200 kg ha-1, and 300 kg ha-1 did not significantly affect to growth and yield of Red Onions. There was not interaction between the rice husk charcoal and KCl fertilizer treatments.
