Long-term reduction of nitrogen fertilizer use through knowledge training in rice production in China (2015, background): “Chinese farmers have relied on their previous experience, which has told them that the use of more fertilizer leads to higher crop yields (Huang et al., 2008).”
Farmers’ risk preferences and pesticide use decisions: evidence from field experiments in China (2016, unknown): “This heavy use of agricultural chemicals has led to environmental degradation and detrimental effects on human health (Huang et al. 2008; Hu et al. 2007; Pemsl et al. 2005; Huang et al. 2003).”
Farmer’s Adaptation to Extreme Weather Events through Farm Management and Its Impacts on the Mean and Risk of Rice Yield in China (2015, unknown): “Having less significant coefficients for input variables (rows 3–7, table 3) is consistent with previous findings on intensive or excessive use of production inputs in China (e.g., Huang et al. 2008; Holst, Yu, and Grun 2013).”
Competing uses for China's straw: the economic and carbon abatement potential of biochar (2015, background): “In fact, fertilizer application rates in China are so high that fertilizer application can be reduced by up to 27% with no impact on yields, and without requiring biochar application (Huang et al., 2008).”
