Solutions for a cultivated planet (2011, background): “Furthermore, agroecological innovations in crop and soil management 1,67 show great promise for improving the resource efficiency of agriculture, maintaining the benefits of intensive agriculture while greatly reducing harm to the environment.”
Mechanisms of Nitrogen Use in Maize (2019, background): “Maize is used for livestock feed, biofuel, and human consumption [31,32], and global demand for maize is anticipated to increase by 16% by 2027, due primarily to a > 50% increase in consumption by livestock [33].”
New technologies reduce greenhouse gas emissions from nitrogenous fertilizer in China (2013, background): “Consequently, food security remains the top priority above other concerns unlike the case in developed economies, where national-scale food security is not a major concern (32).”
Factors Affecting Nitrogen Use Efficiency and Grain Yield of Summer Maize on Smallholder Farms in the North China Plain (2018, background): “0 t ha−1 with an N input from 180 kg N ha−1 to 210 kg N ha−1 [31,42,67], so the maize yield can be increased, and the N input reduced, on smallholder farmers’ fields by optimizing management practices.”
