Nitrogen management in farming systems under the use of agricultural wastes and circular economy

Carbon farming: a circular framework to augment CO2 sinks and to combat climate change

“…Thirdly, it emphasizes revitalizing structures that enable the efficient capture of nutrient cycles and the reduction of productivity losses. 66 An essential element of a circular agriculture model involves integrating mixed crop-livestock methods, promoting organic farming, and adopting water recycling practices. This synergistic approach is vital in pursuing lower CO 2 emissions and the sustainable use of natural resources.…”

“…Farming is a significant driver of global resource utilization, representing approximately 70% of freshwater withdrawals and accounting for roughly 31% of GHGs. 66 This places agriculture as the third-largest contributor to environmental impact, following transportation and housing. 67 India's Third Biennial Update Report, submitted to the United Nations Framework Convention on Climate Change (UNFCCC) in early 2021, indicates that the agriculture sector in India contributes to 14% of the nation's overall GHG emissions.…”

Functionalized Biomass Carbon Dots for Improved Growth of Lettuce and Exocarpium Citri Grandis Saplings

“…However, the use of chemical fertilizers accounts for a disproportionately large share and low utilization efficiency, which has caused serious pollution and damage to the environment. 8 This goes against the concept of green development and sustainable development of human beings. With the rapid development of nanomaterials, due to their small size and easy absorption by plants, the idea of applying nanomaterials to agricultural production has been proposed and is regarded as one of the important driving forces of the agricultural revolution.…”

“…As the population increases and the environment continues to change, the question of how to ensure stable and sustained growth in food production during this process is an important issue. − During food production, efforts have been made to find ways to improve plant growth in order to achieve increasing yields, such as the application of fertilizers, genetic engineering, greenhouse farming, and soilless cultivation. − Among these methods, the application of fertilizers to plants is the simplest and easiest method and is the most widely used. However, the use of chemical fertilizers accounts for a disproportionately large share and low utilization efficiency, which has caused serious pollution and damage to the environment . This goes against the concept of green development and sustainable development of human beings.…”

Genotype-specific nonphotochemical quenching responses to nitrogen deficit are linked to chlorophyll a to b ratios

“…Today many farmers apply nitrogen fertilizer to maize fields in excess of 300 kg/ha/year (Zhang et al ., 2015; Cao et al ., 2018). The cost to farmers of nitrogen fertilizer can exceed $300 ha/year (‘Statista 2022’; Rodríguez-Espinosa et al ., 2023).…”
