Abstract

In Indonesia, tidal swampland is potential to be developed into agricultural land uses. Water management is the key success of farming on the tidal swampland. In the tidal swampland of Kalimantan, Indonesia, a fork irrigation system is widely applied in the water channels to supply irrigation water to the land. Besides irrigation, soil physical characteristics play an important role in controlling water availability for crops. The ability of soil to store water will determine the amount of available water that can be taken up by plants. This research aimed to determine the soil physical properties that are related to water availability in the soils from different land uses in a tidal swamp land area applied with a fork irrigation system. The experiment was conducted in dry season 2012, in Belawang, Barito Kuala district, South Kalimantan province. The soil samples were taken from four land uses, namely rice field, rubber plantation, mixed cropping, and unmanaged land. The soil physical properties, namely soil bulk density, particle density, porosity, texture, pF 1, pF 2, pF 2.54, pF 4, water content, total pore space, rapid drainage pores, slow drainage pores, available water, groundwater level were measured. In addition, the mineralogical properties of the soils were measured as well. The results showed that the physical properties of the soils taken from different land use varied, however, the change of the land use did not cause changes in the soil mineralogical properties. The mineralogy of the soils from different land uses are relatively the same, namely: quartz, illite, and chlorite.

Abstract

Carbon stock on peatlands are large and will be easily emitted if the land is opened or drained, therefore the measurements of  carbon stocks and ash content are important to know the amount of emissions and agricultural sustainability in peatlands. This study aimed to determine carbon stock and ash content on peatlands in the Indonesia Climate Change Trust Fund (ICCTF) located in South Kalimantan on the geographic position S. 03°25’52" and E. 114°47’6.5". The experiment consisted of six treatments of ameliorant materials namely; mineral soil, peat fertilizer A, peat fertilizer T, manure, ash, and control.  The results showed that the variation of peat soil properties was very high at this location. Peat thickness ranged from 36-338 cm, and this led to high variations in carbon stocks ranged between 161.8 – 1142.2 Mg ha-1. Besides ash contents of the soil were also highly varied ranged from 3.4 – 28.5%. This natural variation greatly affected the ICCTF study design. Mineral soil treatment had a mean carbon stock (961.3 ± 61.5 Mg ha-1) which was higher and different from other treatments. High ash content was obtained in the ash treatment (18.6 ± 2.5%) and manure (15.7 ± 3.6%).  It is recommended that the analysis of plant responses and greenhouse gas emissions using a single regression analysis and multiple regression with ash content as one of the independent variables are needed.Keywords: Ash content, carbon stock, peatland,  peat thickness[How to Cite: Nurzakiah S, F Agus, and H Syahbuddin. 2013.
