In South Korea, the standard facility capacity for bioenergy facilities is set at 100 tons per day based on livestock manure amount by bioenergy-related laws. To achieve the government's goals for the energy recovery from livestock manure, there is a need to expand and distribute centralized facilities with a capacity of 100 tons of livestock manure per day. The location and scale of these centralized facilities are influenced by the geographical location and livestock breeding scale of nearby livestock farms. The size of most domestic pig farms is small, thus it is necessary to analyze the distribution and density of medium-sized or larger livestock farms capable of supplying manure to centralized facilities. In this study, kernel density analysis and spatial density analysis were conducted to select suitable regions for centralized biogas facilities for pig manure for Gyeonggi-do. As a result of analyzing the Gyeonggi-do region as a case study, four regions in southern Gyeonggi-do and one region in northern Gyeonggi-do were estimated to be suitable regions. Although it is necessary to confirm specific suitable regions through a feasibility assessment of regions estimated to be suitable regions, it is believed that selecting candidate regions first and conducting a feasibility study through kernel density analysis will save time and help in rational decision-making.

“…Various experiments are being conducted, including studies on the development and cultivation of varieties of feed rice in the general agricultural land, and intended to find the appropriate time for oats to be sown [ 19 , 20 , 21 ]. Furthermore, research has been actively conducted on aspects such as the productivity of forage crops according to the use of anaerobic liquid fertilizer [ 22 ], and the appropriate amount of fertilizer to be employed when cultivating the Barnyard millet for forage [ 23 ].…”

The purpose of this study is to identify the different effects exerted by planting density and nitrogen fertilization on high-salinity reclaimed paddy fields (RPF) and general paddy fields (GPFs), and to find the amount of fertilization and the planting density suitable for the growth of forage rice in each paddy field. Nitrogen fertilization with high-salt and low-salt soils, an untreated control plot, treatment with 200 kg/ha, 300 kg/ha, and 400 kg/ha, and planting densities of 30 cm × 10 cm and 30 cm × 16 cm, growth, and feed values were investigated. In both experimental locations, there was no significant change in the soil due to N treatment, but in the case of RPF, electrical conductivity (EC) decreased significantly from more than 5 dS/m to up to 2.87 dS/m during the yellow ripe stage due to the influence of floods and concentrated precipitation in the fields. In all soils, as both the amount of N treatment and the planting density increased, there was a proportional relationship in which the number of tillers and the dry weight also increased, with the occurrence of lodging also being increased. The dry weight, as expected, was 1.5 times higher at a planting distance of 10 cm, rather than 16 cm. In addition, in both locations, the N treatment led to an increase in the dry weight, but when N treatment reached 400 kg/ha (2.0), the dry weight decreased instead. Moreover, although there was no clear difference in feed value according to N treatment, in RPF, the neutral detergent fiber (NDF) was higher than 60%, the relative feed value (RFV) was less than 98, and the total digestible nutrient (TDN) was also low, confirming that the quality of rice was higher in GPF.
