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

Sugarcane growth and yield are influenced by the interaction between plant factors, soil conditions, climate, and cultivation practices. Climate is an uncontrollable component, so it is an important aspect that must be carefully considered in sugarcane cultivation activities. Three important variables are rainfall, humidity, and temperature, and to date, research related to the relationship between climate variables and sugarcane growth has not been widely conducted. This study aims to determine the relationship between sugarcane growth and climate conditions (rainfall, humidity, and air temperature). This study used three locations: Magelang, Purworejo, and Kulon Progo, in sugarcane areas with the Bululawang variety and plant age. The observed plant growth variables included stem height, stem diameter, number of leaves, number of stems per clump, and number of sugarcane internodes in each field. Meanwhile, the observed climate variables were rainfall, temperature, and humidity (obtained from BMKG). Data analysis was carried out using descriptive quantitative data and a person correlation test using Excel. The results showed that Magelang had the highest rainfall and Kulon Progo had the lowest rainfall. The air temperature in Purworejo was the highest and Kulon Progo had the lowest. The highest humidity is in Purworejo and the lowest humidity is in Magelang. Rainfall has a significant correlation with sugarcane growth, while temperature and humidity have a correlation but are not significant. Rainfall has a very strong and significant correlation with stem diameter (r = -0.835), number of internodes (r = -0.857), and number of stems per clump (r = -0.897). Air temperature and air humidity have a very low and insignificant correlation with all plant growth variables. This indicates that rainfall is the most important climate factor influencing sugarcane growth.

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.

Abstract

Land clearing after harvest in sugarcane cultivation is often done by burning. However, burning influences the ecosystem, such as the chemical and biological characteristics of soil. This research aims to analyze the impact of different methods of clearing sugarcane fields on the chemical and biological conditions of the soil. This research used a non-factorial, completely randomized design (CRD) with two treatments: land clearing with burning and without burning. Each treatment was carried out on an area of 50 m2 with two blocks as repetitions. For chemical and biological analysis, soil samples were taken from pitfall traps and soil monoliths (1 m x 1 m x 30 cm). Two treatments showed significant differences in the total N and available P, and burning reduced 21% the number of organisms significantly. There were significant differences between the two treatments regarding the macrofauna diversity index, species evenness value, and dominance index. Post-harvest burning significantly reduces total N and available P and negatively impacts biological indicators such as organism numbers, diversity, evenness, and dominance index. This decrease in organic matter causes a reduction in the populations of organisms, thus disrupting soil health. Therefore, this study recommends that sugarcane residues be returned to the land as a source of organic matter to maintain soil health, biodiversity, and optimal productivity.
