Cadusafos, an organophosphorus insecticide, has been commonly used against various pests worldwide. Org-anophosphorus pesticides have shorter half-lives and lower toxicities than organochlorine pesticides. However, excessive use of Cadusafos can increase pest resistance and issues with acetylcholine biomagnification, potentially resulting in human toxicity. In this study, we investigated the effect of a Cadusafos-degrading microbial agent (CDMA) prepared using Sphingobium sp. Cam5-1, which was previously reported to effectively degrade residual Cadusafos in soil. Experiments were conducted under both controlled laboratory and green-house field conditions. Under laboratory conditions, CDMA (10 6 cfu/g soil application rate) decomposed 97% of Cadusafos in the soil in the untreated control after 21 days. Additionally, when CDMA (10 6 cfu/g soil) was mixed with quicklime, 99% of Cadusafos was decomposed within 3 days. Under greenhouse field conditions, the combined effect of CDMA (10 6 cfu/g soil) and quicklime was not observed. However, CDMA (10 6 cfu/g soil) application alone was capable of decompos-*

This study evaluated the effect of lignin biochar on Kimchi cabbage cultivation in an upland field. Each of the inorganic fertilizers (IF, applied at 32-7.8-19.8 kg/ 10a=N-P-K), lignin biochar (LBC, applied at 1,000 kg/ 10a), improved LBC (LBC+N, applied at 1,000 kg/10a), and LBC+IF treatments areas were separated by a con-trol (Cn) treatment area. The fresh weight of Kimchi cabbage increased in the order LBC+N > IF > LBC+IF > Cn > LBC treatments, and the length and width of the leaf were ranged from 20.8-25.7 and 13.7-15.8 cm/ plant in all treatments. After Kimchi cabbage harvesting in the LBC+N treatment, soil quality improved bulk density, pH, OM, TN, and Av-P 2 O 5 than those other treatments. In addition, the total N 2 O flux in LBC+N was lower than in IF treatments. Therefore, improved lignin biochar application effectively improves Kimchi cabbage cultivation and can benefit the agricultural environment.
本研究评估了木质素生物炭对高地泡菜种植的影响。无机肥料（IF，施用量为 32-7.8-19.8 kg/ 10a=N-P-K）、木质素生物炭（LBC，施用量为 1,000 kg/10a）、改良 LBC（LBC+N，施用量为 1,000 kg/10a）和 LBC+IF 处理区各由一个控制（Cn）处理区隔开。在所有处理中，泡菜白菜鲜重的增加顺序为 LBC+N > IF > LBC+IF > Cn > LBC，叶片的长度和宽度分别为 20.8-25.7 厘米/株和 13.7-15.8 厘米/株。LBC+N 处理的泡菜收获后，土壤质量的容重、pH 值、OM 值、TN 值和 Av-P 2 O 5 均比其他处理有所改善。此外，LBC+N 处理的总 N 2 O 通量低于 IF 处理。因此，改良木质素生物炭的应用能有效改善泡菜白菜的种植，并有利于农业环境。

Global concern over climate change, driven by green-house gas emissions, has prompted widespread interest in sustainable solutions. In the agricultural sector, biochar has emerged as a focal point for mitigating these emissions. This study investigated the impact of continuous biochar application on CO 2 and N 2 O emissions during the spring cabbage cultivation period. Greenhouse gas emissions in the biochar treatment groups (soils treated with 1, 3, and 5 tons/ha of rice husk biochar) were compared to those in the control group without biochar. During the spring cabbage cultivation period in 2022, the total CO 2 emissions were in the range of 71.6-119.0 g/m 2 day, and in 2023, with continuous biochar application, they were in the range of 71.6-102.1 g/m 2 day. The total emissions of N 2 O in 2022 and 2023 were in the range of 11.7-23.7 and 7.8-19.9 g/m 2 day, respectively. Overall, greenhouse gas emissions decreased after biochar treatment, confirming the positive influence of biochar on mitigating greenhouse gas release from the soil. Nevertheless, further research over an extended period exceeding five years is deemed essential to delve into the specific mechanisms behind these observed changes and to assess the long-term sustainability of biochar’s impact on greenhouse gas dynamics in agricultural settings.
由温室气体排放引起的全球对气候变化的关注，促使人们对可持续的解决方案产生了广泛兴趣。在农业领域，生物炭已成为减少这些排放的焦点。本研究调查了连续施用生物炭对春季白菜种植期间 CO 2 和 N 2 O 排放的影响。生物炭处理组（使用 1、3 和 5 吨/公顷稻壳生物炭处理的土壤）的温室气体排放量与未使用生物炭的对照组的温室气体排放量进行了比较。在 2022 年春季白菜种植期间，CO2 总排放量在 71.6-119.0 克/米 2 天之间，而在 2023 年连续施用生物炭的情况下，CO2 总排放量在 71.6-102.1 克/米 2 天之间。2022 年和 2023 年的 N 2 O 排放总量分别为 11.7-23.7 克/米 2 天和 7.8-19.9 克/米 2 天。总体而言，生物炭处理后的温室气体排放量有所减少，这证实了生物炭对减少土壤温室气体排放的积极影响。不过，为了深入研究观察到的这些变化背后的具体机制，并评估生物炭对农业环境中温室气体动态影响的长期可持续性，进一步开展超过五年的研究被认为是必不可少的。

The golden apple snail ( Pomacea canaliculata ) has been utilized as a natural and eco-friendly control of weeds in rice paddy fields. However, P. canaliculata can damage other crops. In this study, the effectiveness of plant extracts from various natural sources that are reportedly effective against pests in the control of P. canaliculata was investigated. The four plant extracts were effective against P. canaliculata and ranked in descending order as green tea seed ( Camellia sinensis ) > root of red spider lily ( Lyc-oris radiata ) > leaves of tobacco ( Nicotiana tabacum ) > root of sophora ( Sophora flavescens ). The mortality rate of P. canaliculata was increased using 200 to 2000 mg/kg of green tea seed powder. However, shrubby sophora root extract did not significantly increase the mortality rate. The LC 50 and LC 90 of green tea seed, tobacco leaves, shrubby sophora root, and red spider lily root were 900 and 2800 mg/L, 956 and 2320 mg/L, 2162 and 5325 mg/L, and 512 and 1054 mg/kg, respectively.

Large amounts of organic wastes generated in agricultural environments such as crop residues and livestock manure adversely affect the environment. Anaerobic digestion can reduce the amount of organic wastes and convert them into energy at the same time. Efforts are being made to further increase the energy conversion efficiency by using co-anaerobic digestion using two or more substrates. Tomatoes, rice straw, cattle manure, and cattle feces (CF) were used as substrates for anaerobic digestion. Each substrate was subjected to anaerobic digestion and the cumulative biochemical methane production potential was measured

Physiological disorders in pear fruit are mainly caused by problems during the growing season, such as lack of calcium in the soil, poor drainage, low porosity, vigorous pruning, and excessive fruiting. In this study, soil physicochemical properties and leaf characteristics were analyzed in pear orchards in four regions of Korea where chlorosis symptoms occurred to determine the causes of chlorosis. The color of chlorotic leaves was diagnosed using the naked eye or SPAD and Hunter values. The soil of the chlorotic orchard had a significantly higher soil pH than that of the regular orchard. Although adequate soil depth was not significantly associated with chlorosis, combined with over-fertilization of the soil with lime, it could potentially impair plant iron uptake. Chlorotic leaves had significantly lower iron and calcium contents and significantly higher magnesium contents than those of regular leaves. Therefore, the intensive occurrence of chlorosis during secondary shoot development around June and July when it is hot and humid may be due to impaired iron and calcium absorption, leading to physiological disorders. To solve this problem, avoiding the over-application of lime and applying foliar fertilizers containing chelated iron is recommended.

Miscanthus sinensis Andersson (Poaceae) cultivars exhibit excellent visual appeal as ornamental grasses and adapt well to diverse environmental conditions. This study focused on assessing the growth response and landscape durability of seven popular Miscanthus cultivars (‘Gold Breeze’, ‘Strictus’, ‘Morning Light’, ‘Vari-egatus’, ‘Gracillimus’, ‘Kleine Fontäne’, ‘Common’) under drought, rainfall and low temperature condition. The test cultivars were transplanted and cultivated on research plots in 2013, with data collected from June 2017 to February 2018. Plant materials were categorized into three types based on the amount of the water lost; group I (‘Kleine Fontäne’, ‘Variegatus’, ‘Strictus’), experiencing the most significant water loss; group II (‘Common’, ‘Gracillimus’); and group III (‘Gold Breeze’, ‘Morning Light’) where the least water loss occurred. The drought resistance index (DRI) remained low as water shortage conditions persisted. The lodged angle underwent more pronounced changes in reproductive growth stage than in vegetative growth stage, notably decreasing after heading. Discoloration patterns were classified into two types: group I (‘Common’, ‘Gold Breeze’, ‘Kleine Fontäne’, ‘Strictus’) and group II (‘Gra-cillimus’, ‘Morning Light’, ‘Variegatus’) based on the periods of peak duration.
