“…Soil organic matter, total N content, and available N are the main components of soil fertility, which plays a crucial role in regulating soil carbon and N cycling, soil aeration, nutrient retention and use efficiency, gaseous emissions, plant growth and development 52–54 . In this study, therefore, soil N sources for plant uptake and utilization, such as STN, AN, and OM were considered as specific indicators of soil fertility for evaluating the effects of N management on crop productivity.…”

BACKGROUND Global food security faces a number of challenges due to increasing population, climate change, and urbanization, while excessive use of nitrogen fertilizers has become a major challenge for sustainable, intensive agriculture. Assessing the impact of agronomic management practices on seed yield, grain quality, and soil fertility is a critical step in understanding nutrientuse efficiency. RESULT The comprehensive evaluation index had good fitness to that of single attribute (i.e. seed yield, crop quality and soil fertility), indicating that the comprehensive evaluation index was reliable. Applying controlled‐release urea (rice in wheat and oilseed rape field: 150 kg N ha−1, other crops: 120 kg N ha−1) plus common urea (30 kg N ha−1) incorporating straw from the previous season across the growing season for cereal and oilseed crops showed a slight improvement in seed productivity and Nuse efficiency among three cropping systems in the traditional evaluation method. Compared with local farm practice (applying common urea of 150 kg N ha−1), applying these practices in combination based on the outcome of the comprehensive evaluation index method decreased the seed yield by −1.27 ~ 29.8% but improved quality and soil fertility for the paddy‐upland cropping system, respectively. CONCLUSION Properly managing N application by applying partial and fully controlled release of urea with or without straw incorporation for a specific crop system has the potential to provide a better compromise among yield, grain quality, and soil fertility in southern China. © 2020 Society of Chemical Industry

“…Additionally, different crops require different irrigation, fertilization, and other management practices, which can further impact the SOC levels in agricultural land (Z. Luo et al, 2010;Oechaiyaphum et al, 2020). The higher SOC content in VF compared to DL could be attributed to fertilization differences between vegetable and DL crops production in China.…”

Exploring the relationship between soil organic carbon (SOC) and different farmland utilization types can contribute to achieving carbon neutrality in agriculture. Over the past few decades, numerous researchers have conducted a multitude of studies on the effects of farmland utilization types on SOC in China, and these studies have yielded a wealth of data from field experiments. However, these experiments are limited in that they lack sufficient quantitative analyses of studies conducted on regional or national scales. In this study, we analyzed the three most common farmland utilization types (paddy field [PF], dry land [DL], and vegetable field [VF]) in China using a national‐scale meta‐analysis and included data from 108 observations from 28 studies in the field. In this meta‐analysis, we conducted three comparisons (control vs. treatment): (a) PF versus DL, (b) PF versus VF, and (c) DL versus VF. The results showed that in comparison (a), DL had a significantly lower SOC than PF (ln R++ = −0.463, 95% confidence intervals [CIs] = −0.580 ~ −0.345), with DL showing 37.1% lower SOC than PF. In comparison (b), although there was no statistically significant difference between PF and VF (ln R++ = −0.078, 95% CIs = −0.167 ~ 0.011), VF had 7.5% lower SOC than PF. In comparison (c), VF had significantly higher SOC than DL (ln R++ = 0.227, 95% CIs = 0.147 ~ 0.307), with VF showing 25.5% higher SOC than DL. It should be noted that the effects of farmland utilization types on SOC content observed in China varied depending on different factors such as the regions, climatic conditions, and cropping systems. In conclusion, SOC content could be affected by farmland utilization types. Therefore, in order to promote the development of low‐carbon agriculture in China, it is important to consider farmland utilization types in agricultural production, as well as to consider carbon budgets, food security, and field practices to maximize agronomic and environmental benefits.

“…On the other hand, it has been demonstrated that land management practices affect agricultural productivity. Long-term organic land management, for instance, can increase soil organic matter availability and rice productivity in Thailand (Oechaiyaphum et al, 2020). According 2011), organic plant cultivation provides a number of benefits, including more effective water use, less soil damage, and resistance to pests and diseases.…”

The integration of learning activities in schools and environmental education is considered capable of increasing students’ knowledge, understanding, and positive behavior towards the environment. The aim of the environmental education program at Taman Kehati Subang was to investigate its role in supporting environmental education activities of the students of SMK Tri Surya Bangsa, Subang. It was conducted on August 21, 2020 and was attended by 10 representatives’ students of class X, XI, and XII and 2 accompanying teachers. Outdoor activities, games, and field practice were used to deliver the material. It includes organic cultivation, biodiversity conservation, nurseries and compost making, cipondoh water sources, and soil and water conservation. Our evaluation showed that students hold high agreement that Taman Kehati has various types of plants and suitable to support environmental education activities in schools. Students assessed that a visit to Taman Kehati provided new experiences that could increase their knowledge of environmentally natural resource management. Delivering material with a combination of outdoor activities, field practice, and games makes them easy to be understood and can be practiced daily. It can be concluded that students and teachers generally consider that Taman Kehati is suitable to support the integration of learning in schools and environmental education. Students were very satisfied with the environmental education activities at Taman Kehati, Subang
