“…As the results showed, irrigation increased the soil moisture at the surface layer gradually and the soil moisture was influenced by the depth and the irrigation amount (Figures 2 and 3), which was consistent with the results of previous studies [27,40]. In our study, the rate of N application did not significantly affect the variation in soil moisture (Figures 2 and 3), which was consistent with the results of Kong et al [41].…”

For improving water scarcity and groundwater pollution from agriculture, two-year experiments (2011)(2012)(2013) with three water levels (0.3, 0.5 and 0.8 evaporation (E) in 20-cm-diameter pans) and four nitrogen (N) levels (120, 140 and 190 kg·ha in 2013) were conducted to study effects of water and N availability on water movement and N transport for a wheat crop under drip irrigation in the North China Plain. The results indicated that under drip irrigation, deep percolation at 1-m depth was stable at 0.5-0.8 E with the same N rate for winter wheat. At 0.5-0.8 E, deep percolation was also relatively stable with increasing N rate from 120 to 140 kg·ha . The irrigation schedule and N rates only affected N leaching below the root zone of winter wheat (60-cm depth), while the N residual in the soil layer presented more risk to the environment than N leaching. In general, the 290-kg-ha −1 N level was not recommended using drip fertigation for winter wheat in the North China Plain. The empirical equation given by the Ministry of Geology and Mineral Resources was also not recommended for estimating the drainage under drip irrigation. OPEN ACCESSWater 2015, 7 6652

“…Numerical modeling is an efficient tool for understanding the physical, chemical and biological processes affecting nitrate-N transport, as well as in predicting and managing nitrate-N pollution (van der Laan et al, 2014). Numerous studies have been published to model the fate and transport of nitrogen in soils, focusing either on nitrogen leaching in the root zone (Nakamura et al, 2004;Skaggs et al, 2004;Gärdenäs et al, 2005;Hanson et al, 2006;Tafteh and Sepaskhah, 2012;Arbat et al, 2013;Deb et al, 2015;Iqbal et al, 2016) or on nitrate-N transport and transformation in the saturated zone (MacQuarrie et al, 2001;Lee et al, 2006). Various models have been applied to simulate soil water and nitrogen dynamics in soils, such as soil-crop model (STICS) (Ledoux et al, 2007;Poch-Massegú et al, 2014;Plaza-bonilla et al, 2015), Root Zone Water Quality Model (RZWQM) (Ma et al, 1998), Agricultural Production Systems SIMulator (APSIM) (Keating et al, 2003), Cropping System Simulation Model (CropSyst) (Stöckle et al, 2003), Soil Water Balance Model (SWB-Sci) (van der Laan et al, 2014), as well as simple models solving water and nitrate-N production functions (Cabon et al, 1991).…”

Contamination of groundwater from nitrogen fertilizers in agricultural lands is an important environmental and water quality management issue. It is well recognized that in agriculturally intensive areas, fertilizers and pesticides may leach through the vadose zone and eventually reach groundwater. While numerical models are commonly used to simulate fate and transport of agricultural contaminants, few models have considered a controlled field work to investigate the influence of soil heterogeneity and groundwater flow on nitrate-N distribution in both root zone and deep vadose zone. In this work, a numerical model was developed to simulate nitrate-N transport and transformation beneath a center pivot-irrigated corn field on Nebraska Management System Evaluation area over a three-year period. The model was based on a realistic three-dimensional sediment lithology, as well as carefully controlled irrigation and fertilizer application plans. In parallel, a homogeneous soil domain, containing the major sediment type of the site (i.e. sandy loam), was developed to conduct the same water flow and nitrate-N leaching simulations. Simulated nitrate-N concentrations were compared with the monitored nitrate-N concentrations in 10 multi-level sampling wells over a three-year period. Although soil heterogeneity was mainly observed from top soil to 3 m below the surface, heterogeneity controlled the spatial distribution of nitrate-N concentration. Soil heterogeneity, however, has minimal impact on the total mass of nitrate-N in the domain. In the deeper saturated zone, short-term variations of nitrate-N concentration correlated with the groundwater level fluctuations.

“…Arbat el al. [46] also did not find significant differences in yields between treatments that received low rates of mineral N with fertigation but received 120 kg N/ha from pig slurry at pre-planting and treatments that received higher rates of mineral N as a side dressing.…”

“…For example, according to Yin et al [27] and Sandhu et al [36], the use of a drip irrigation system and six events with 10-36 mm per event is useful to fertigate an intensified maize crop system. Conversely, in field experiment conducted by Arbat et al [46], the nitrogen demand of plants was satisfied using only three events per season.…”

“…Furthermore, Berenguer et al [52] previously concluded that optimal grain yields can be obtained by using a pig slurry as a base dressing without any side-dressed mineral N. On the other hand, Arbat et al [46], Sandhu et al [36], and Wu et al [53] promote splitting the base dressing and fertigation events according to crop N uptake patterns to increase the NUE, while Yague and Quilez [45] recommended not applying doses higher than 130 kg N/ha as a base dressing to reduce the risk of nitrate leaching due to late spring rains. N uptake by the plants at harvest (Figure 4) reached its maximum value at site 1 in P-F in 2018, with 238 kg N/ha, and the minimum (136 kg N/ha) at site 2 in D-F3 during the same year.…”

Fertigation of Maize with Digestate Using Drip Irrigation and Pivot Systems

Digestate is a nutrient-rich fertilizer and appropriate techniques are required for its application during the maize season to reduce losses and increase the nitrogen use efficiency (NUE). The performance of two different fertigation techniques (drip irrigation and pivot) were assessed using the digestate liquid fraction. A two-year field test was carried out at two different sites in Lombardy, northern Italy. At each site, fertigation with pivot (P-F, site 1) or drip (D-F, site 2) systems was compared to reference fields where the same irrigation techniques without addition of digestate were used. During the two seasons, the performance of the fertigation systems, amount of fertilizers used, soil nitrogen content, yields, and nitrogen content of the harvested plants were monitored. The digestate application averaged 5 m3/ha per fertigation event with P-F and 4.9 m3/ha with D-F corresponding, respectively, to 28 and 23 kg N/ha. Both irrigation systems were suitable for fertigation provided that the digestate was adequately filtrated. Our results suggest that fertigation with digestate, if properly managed, can be applied during the growing season up to the full amount of nitrogen required by the crop.
