“…This tends to result in deep nutrient-rich soil layers. In our experiment a uniformly nutrient-rich soil profile (with greater total nutrient load) did not increase shoot growth (P=0.069) or plant nitrogen uptake (Table 2) to winter wheat (n=370)), does not significantly enhance grain yield (Cui et al 2006(Cui et al , 2010Peng et al 2012;Zhang et al 2012), however, there have been reported decreases in crop yield . These are likely to be due to the effect of nutrient placement on root growth (Fig.…”

“…Thus, heavy rainfall and irrigation during the summer months in the North China Plain may cause great nitrate leaching in soil profile (Wang et al 2010). Soil nitrate-N content in the top 90 cm of the soil profile should be maintained within the range of 154-159 kg N ha −1 for high yield wheat production (Cui et al 2013) and to reduce the N losses to the environment (Cui et al 2006). This tends to result in deep nutrient-rich soil layers.…”

Background and aims We were interested to determine the effects of horizontal stratification of nutrient-rich zones within different layers of the soil profile in water-limited environments on root growth and crop yield. This is practically relevant to large areas of China, many of which have been over-fertilized. Methods We used soil-filled rhizotrons 1.4 m deep to grow wheat. Three different nutrient-rich horizontal stratifications were used at depths of 0-40, 60-100 and 0-140 cm. The soil was packed to a density of 1.5 g cm −3

“…However, some fragmentary research on this topic has shown that INS is high and should be considered in the N fertilization recommendation in the NCP. Cui et al (2006) observed that wheat grain yield response to add N was unlikely if soil nitrate-N exceeded 200 kg N ha -1 in this region. Ju et al (2006) reported that the residual soil nitrate-N after maize harvest was 275 kg N ha -1 in the top 90 cm soil profile and 213 kg N ha -1 at 90-180 cm soil depth in this region.…”

Estimating indigenous nitrogen supply (INS) by measurement of crop N uptake in N omission plots for site-specific N management is not feasible on a routine basis because it involves destructive plant sampling and plant tissue analysis, which is time-consuming and expensive. The objective of this study was to determine the amount of INS and develop a method to estimate it using soil testing in the North China plain (NCP). On-farm experiments at 229 sites were conducted from 2003 to 2005 in seven key winter wheat (Triticum aestivum L.)/ summer maize (Zea mays L.) production regions of the NCP. The mean INS during the wheat-growing season was129 kg N ha -1 with a range from 62 to 212 kg N ha -1 , and it varied from 69 to 202 kg N ha -1 with a mean of 142 kg N ha -1 during the maizegrowing season. Considering all sites, the variability of INS was not simulated by initial soil N min or apparent N mineralization (N organic ) alone, while together they could explain about 38% and 60% of INS during the wheat and maize-growing seasons, respectively. During the wheat-growing season, mean N organic was 63 kg N ha -1 , and 59% and 33% of its variation could be explained by SOM in high-yielding regions (mean yield, 7.6 t ha -1 ) and low-yielding regions (mean yield, 5.3 t ha -1 ), respectively. Mean N organic during the maize-growing season was 109 kg N ha -1 , 22% of which could be explained by SOM across all sites. An average of 40% and 42% of INS variation could be explained by both SOM and initial soil N min content during the wheat and maize-growing seasons, respectively. We conclude that the accuracy of estimating crop N requirement for site-specific N management will be increased by using initial soil N min and SOM.

“…The dose of 200 kg N/ha, compared to dose of 150 Kg N/ha, significantly increased the protein content (Maqsood et al, 2000;Cui et al, 2005 andHussain et al, 2006). The reduction of N reduced grain yield, agronomic NUE, grain protein content, grain N content and bread volume but caused increasing of thousand kernel weight (Khalilzadeh et al, 2011).…”
