“…Nitrogen fertilizer is the most critical nutrient associated with crop productivity in an intensive cropping system. Supplementation with an appropriate quantity of N fertilizer can increase crop productivity as it increases leaf development and maintenance as well as the rate of photosynthesis 14,15 . For example, N fertilizer has been estimated to have contributed around a 40% increase in per capita food production in the past 50 years 16 .…”

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

“…Almost all farming procedures in SCS, including soil preparation, sowing, and harvesting, can be done by machinery, which sharply improves agricultural labour productivity (Baležentis et al, 2020;Liu, S. et al, 2018). The use of abundant nutrients, such as chemical nitrogen, phosphorus, and potassium fertilisers, allows for more direct control and precision in the delivery of nutrients that would maintain soil fertility levels for supporting higher yields (Cabrera and Solis-Perez, 2017). However, this comes at the expense of environmental resources, as the long-term application of chemical fertiliser would destroy soil structure, and may also cause soil acidification and water pollution (Wallace, 1994).…”
