“…Thus, PASPT3 led to a higher level of available N in the soil, leading to the highest crop N uptake and lowest apparent N losses at Wenjiang. This was in agreement with the result of Qiao et al (2013), who indicated that the potential available N in the soil might lead to higher N accumulation.…”

“…Previous studies have indicated that N accumulation and redistribution of crop mainly depend on the N rate and application time Peng et al, 2006;Qiao et al, 2013). N application was found to have significant influences on N accumulation and redistribution in this study, whereas the total N accumulation was increased with an increase in N rate (Jiang et al, 2004;Qiao et al, 2013). Further, the N redistribution in the leaf lamina and stem plus sheath of each treatment had a valuable contribution to the N accumulation in grains, with NRCR ranging from 30.6% to 58.6% and from 3.8% to 19.5%, respectively.…”

“…Hence, farmers commonly apply excessive N to increase crop yield (Ju et al, 2009). However, this might result in not only crop lodging, ripening delay, and poor grain yield and quality Ye et al, 2013;Zhang et al, 2014) but also low N use efficiency, massive N losses, high production cost, and environmental pollution (Peng et al, 2006;Qiao et al, 2013;Xu et al, 2012a).…”

“…1). This result suggested that the dry matter accumulation of rice could not always be promoted by increasing biochar application; this may be due to the fact that biochar application had a negative impact on the uptake of soil nutrients by rice (Peng et al 2007;Qiao et al 2013;Ye et al 2013).…”

Ammonia volatilization from agricultural land has a negative impact on the atmospheric, aqueous, and land environments. However, this process is still not fully understood. In this study, a 2-year field experiment is conducted in the Taihu Lake region of China to monitor ammonia volatilization from a paddy soil. The ammonia volatilization losses are in the range of 43.4 to 53.6 kg N ha −1 in the year 2013 and 25.9 to 35.4 kg N ha −1 in the year 2014, which account for 19.7% to 19.9% and 11.8% to 13.1% of the applied nitrogen with two different N treatments (N1: 220 kg N ha −1 , N2: 270 kg N ha −1 ). The ammonia volatilization loss is highest during the basal fertilizer application, followed by the tillering and the ear-differentiation stages. Then, two empirical models and one mechanistic model are used to simulate the ammonia volatilization process. These models are calibrated and validated with field experimental data. The results show that none of the three models accurately predict the ammonia volatilized from the rice field (R 2 < 0.40), however, among the three models evaluated, the mechanistic model is more effective in simulating the ammonia volatilization process (R 2 = 0.38).
