“…Table 3 shows the effects of Bokashi compost on bell peppers plant growth. Tong et al (2021) declared that the plant height difference could be due to a high level of sodium ion (Na + ) in the medium of Bokashi that can cause salinity stress (López-Serrano et al, 2021). Nutrient deficiencies could also lead to slow growth.…”

Food waste and leftovers were common materials that were currently used as bio-compost or soil conditioners upon decomposition. Food waste was a source of food that has declined nutritional value and is not deemed favorable for human consumption. Leftovers were defined as uneaten edible remains of a meal. Biodegradation of these components contributes to many macronutrients, including carbon (C), hydrogen (H), nitrogen (N), phosphorus (P), and potassium (K) in the compost, which makes it a suitable growing condition for plants. In this study, the main sources of research data were one hundred thirty-one scientific articles relating to food waste treatment methods and the growth quality of plants over the last few years. This review was the consensus of the role and characteristics of food waste and leftovers as fertilizers. Moreover, the paper briefly discusses the different composting methods for these materials and their corresponding effects on the growth quality of plants.

“…All of the necessary components for plant growth are provided by different chemical combinations [16]. Bokashi compost is one of the potential fertilizer sources for organic hydroponics [17]. In this function, the use of bokashi stands out since it increases the number of leaves, the plant's biomass, and its nutritional content [18].…”

Organic liquid fertilizers (OLF) are made up of essential plant nutrients, as well as beneficial microbes that assist in the recycling of organic waste. The purpose of this study was to determine the macronutrient content of organic liquid fertilizers and compare the growth performance of mustard greens under Wick System hydroponic conditions. Market wastes also known as vegetable wastes, were utilized to produce organic liquid fertilizers and compare it to commercial fertilizer (Nutrient Solution, NS). The vegetable wastes were fermented with water and Effective Microorganisms (EM) Bokashi separately. The ratios used for fermentation are 2 kilograms of vegetable wastes, 0.5 litres of water and 100 grams of EM Bokashi. A parameter study on the OLF and OLF with Bokashi to determine the nitrogen (N), phosphorus (P) and potassium (K) were done. Thereafter, four Wick System (pure water, OLF, OLF with Bokashi and NS) were setup to monitor the growth performance of mustard greens twice a week. The organic liquid fertilizers are produced after 40 days of fermentation and used at a dilution of 1: 10 in the hydroponic system. The OLF and OLF with Bokashi showed the ranges of pH values as 5.1 and 4.6 respectively. The results for the hydroponic system showed that OLF demonstrated the best growth performance. The number and size of leaves and the height of the plants in the NS hydroponic system were almost similar to the plants in OLF hydroponic system. The colour of plants in OLF changed slightly to yellowish green towards the end of the growing season. The life spent of mustard greens in OLF with Bokashi hydroponic system was the least compared to other hydroponic system. This study showed that organic liquid fertilizer is as effective as commercial liquid fertilizer. Considering, it has all the nutrients that plants need to grow.

“…The paprika (Capsicum annum L.) cultivated in greenhouses is classified under the Solanaceae family and is considered an economically important crop in most regions of the world [14]. Paprika plants prefer mild climates and are sensitive to high air temperatures and intense sunlight, with the optimal air temperature for their growth being approximately 20-25 • C [15].…”

Ensuring food security has become of paramount importance due to the rising global population. In particular, the agriculture sector in South Korea faces several challenges such as an aging farming population and a decline in the labor force. These issues have led to the recognition of smart farms as a potential solution. In South Korea, the smart farm is divided into three generations. The first generation primarily concentrates on monitoring and controlling precise cultivation environments by leveraging information and communication technologies (ICT). This is aimed at enhancing convenience for farmers. Moving on to the second generation, it takes advantage of big data and artificial intelligence (AI) to achieve improved productivity. This is achieved through precise cultivation management and automated control of various farming processes. The most advanced level is the 3rd generation, which represents an intelligent robotic farm. In this stage, the entire farming process is autonomously managed without the need for human intervention. This is made possible through energy management systems and the use of robots for various farm operations. However, in the current Korean context, the adoption of smart farms is primarily limited to the first generation, resulting in the limited utilization of advanced technologies such as AI, big data, and cloud computing. Therefore, this research aims to develop the second generation of smart farms within the first generation smart farm environment. To accomplish this, data was collected from nine sensors spanning the period between 20 June to 30 September. Following that, we conducted kernel density estimation analysis, data analysis, and correlation heatmap analysis based on the collected data. Subsequently, we utilized LSTM, BI-LSTM, and GRU as base models to construct a stacking ensemble model. To assess the performance of the proposed model based on the analyzed results, we utilized LSTM, BI-LSTM, and GRU as the existing models. As a result, the stacking ensemble model outperformed LSTM, BI-LSTM, and GRU in all performance metrics for predicting one of the sensor data variables, air temperature. However, this study collected nine sensor data over a relatively short period of three months. Therefore, there is a limitation in terms of considering the long-term data collection and analysis that accounts for the unique seasonal characteristics of Korea. Additionally, the challenge of including various environmental factors influencing crops beyond the nine sensors and conducting experiments in diverse cultivation environments with different crops for model generalization remains. In the future, we plan to address these limitations by extending the data collection period, acquiring diverse additional sensor data, and conducting further research that considers various environmental variables.
