Abstract

The main constraint in the management of peatlands include: high soil acidity, very low of nutrient availability  especially NPK. The  study aimed to determine the role of biochar to improve soil properties and paddy growth in peatlands. The study  conducted in  Landasan Ulin rural, Gambut district,   Banjar regency, South Kalimantan. The study was conducted from June to October 2012. Research arranged in a randomized block design, with three replications. The treatment given was a combination of the type and dose of ameliorant i.e. the 3 types of ameliorant: F1 (50% purun tikus grass + 50%  agricultural weed), F2 (16.7% chicken manure + biochar 83.3%), F3 (9% chicken manure + 91% purun tikus grass), with a dose of 2.5, 5 and 7.5 t ha-1 and control. The results showed that treatment of biochar could to increase soil pH, total N, and exchangable P (Bray I) though not significant, and significant  in increasing the exchangable K compared to controls. On the growth of rice plants giving biochar can increase plant height, number of tillers and number of panicles compared to controls. Key words: biochar, improve of soil properties, peat, growth, paddy

Abstract

Peat land has specific character, depends on depth of peat and peat decomposition rale.Earthworms has a role in decomposition,carbon cycle, nutrient redistribution, bioturbation and cycle of nutrient.The aim of the research was to identify the population and diversity of earthworms on peat soil in central Kalimantan and to get species of dominant earthworm in peat land.The research was carried out in several peat land use in Basarang and Kalampangan, Central Kalimantan within dry and rainy season.The collection of earthworms was by using hand sorting method. The result showed that population of earthworms on mulch was higher than the deep peat.Land use influenced population and diversity of earthworm. The population and diversity of earthworms were highest on pineapple (shallow peat soil).The dominant species earthworm in peat land was Iomoscolex corethurus.

Abstract

Peat swamp forest is a unique and fragile ecosystem, with specific flora and fauna that play important roles in maintaining healthy natural conditions with high economic values. This habitat also has important role for equilibrium and maintenance of living environment such as water reservoir, carbon storage, climate change, and biodiversity. Utilization of peatland for agriculture, plantations, and other activities often lead not only to controversy, but also cause land and ecosystem degradation, including water resources availability. The objective of this research was to study comprehensive ecohydrology aspects in ex-mega rice project in Central Kalimantan in order to support sustainable agricultural practices and water resources management in peatland areas. The results of the study showed that the sustainability of agricultural systems in peatland was strongly influenced by ecological aspect. This aspect can be carried out from the condition of water management system, water color condition, and possible incidence of fires. The level of suitability for crops plantation was low (S3), with the limiting factors of pH, nutrient availability, and the risk of inundation. In this case, water gates should be installed to improve water management system. Water quality in this area was typical of peat water and do not meet the requirement for daily use for the local people.
