Abstract

This study aimed to assess the physical and chemical characteristics of soil at four different locations in Gunungkidul Regency, Yogyakarta Special Region, which are representative areas of dryland agroecosystems. The study locations included Sumberejo (Karangmojo), Bandung (Playen), Pringombo (Rongkop), and Gading (Playen). Parameters observed included moisture content, soil pH, soil consistency (dry and wet), specific gravity, organic matter content, and soil texture. The analysis results showed that the highest moisture content was found at Location 3 (8.30%), while the lowest was at Location 1 (6.25%). The soil pH ranged from 6.4–8.1, indicating a soil acidity level ranging from neutral to slightly alkaline. Soil consistency varied from slightly hard to very hard, and from sticky to very sticky under wet conditions. All locations had very high organic matter content, indicating good soil fertility potential. The soil texture was dominated by silt loam, which has a high water and nutrient storage capacity but requires proper aeration management. The results of this study are expected to form the basis for a strategy for sustainable dry land management in the Gunungkidul region.

Abstract

The type of vegetation and soil organic matter affect the carbon fraction, nitrogen fraction and soil carbon stocks that contribute to the global carbon cycle. Therefore, the calculation of the composition of the fractions in different land covers is very important as a potential indicator of the effect of land management practices on soil organic carbon dynamics and supports the reduction of carbon dioxide (CO2) and soil carbon storage. This research aimed to determine the composition of the carbon fraction, nitrogen fraction and soil carbon stock in different land cover. There were six types of land cover with vegetations of 10-year-old bamboo, 30-year-old bamboo, 50-year-old bamboo, bulrush, a mixture of brushwood and bulrush, and a mixture of Albizia falcataria and brushwood, each of which was sampled three times. Soil samples were used to determine microbial biomass, particulate organic, humic acid, fulvic acid and soil carbon stock. The six land cover types showed significant differences in all fractions and soil carbon stocks. Fifty-year-old bamboo vegetation has the highest carbon storage of 0.029 g g-1 soil. The stable carbon fraction, in the form of humic acid and fulvic acid, in 50-year-old bamboo vegetation is more excellent than that in other vegetation. This study shows that 50-year-old bamboo vegetation has the potential to sequester carbon and store carbon in forms that decompose slowly, namely humic acid and fulvic acid, in the soil for a longer period.
