“…Published data used to calculate N inc were limited to Northern Great Plains research in which both grain yield and N 2 fixation values were reported as a minimum requirement (Table 1). In most instances, estimates of N 2 fixation were determined using 15 N enriched or natural abundance methods, although a limited number of studies used a difference method [i.e., a comparison of the N uptake in the fixing crop to a nonfixing reference crop, e.g., Soon and Arshad (2004)] to estimate N 2 fixation.…”

Nitrogen Economy of Pulse Crop Production in the Northern Great Plains

Previously published data were used to examine the N economy of pulse crops typically grown on the Northern Great Plains with the goal of assessing the potential contribution of field pea (Pisum sativum L.), lentil (Lens culinaris Medik.), chickpea (Cicer arietinum L.), common bean (Phaseolus vulgaris L.), and faba bean (Vicia faba L.) to soil N accretion. Incremental changes in soil N associated with the pulse crops (i.e., the nitrogen increment, Ninc), were strongly correlated to N 2 fixation and were highly variable. Data suggest that crops that can achieve relatively high levels of N 2 fixation, such as faba bean, field pea, and lentil are more likely to contribute positively to the overall N economy, particularly when a cropping system is evaluated over a long term. In contrast, pulse crops that typically achieve only modest levels of N 2 fixation such as desi and kabuli chickpea and common bean are more likely to be either N neutral or contribute to a soil N deficit. Because of extreme variability in levels of N 2 fixation achieved, presumably reflecting variability in soil productivity as well as variations in local climate and weather, the Ninc of pulse crops likewise is highly variable. Thus, the N contribution to a subsequent crop is difficult to predict with any certainty, particularly on a yearly or short-term basis.

“…Variation in the amount of N fixed by various pulse species has been reported by different groups in the past. Jensen et al (2010) reported 83 kg ha −1 biological nitrogen fixation by pea, while the quantity was 61 kg ha −1 according to Soon and Arshad (2004). In the study of Jensen et al (2010), biological nitrogen fixation by chickpea, lentil, and faba bean was 54, 50, and 135 kg ha −1 , respectively, while Peoples et al (2009) showed that biological nitrogen fixation by chickpea, pea, and faba bean was 54, 83, and 118 kg ha −1 , respectively.…”

Biological nitrogen fixation by pulse crops on the semiarid Canadian Prairie

Pulses play a significant role in nitrogen cycling as they fix atmospheric N 2 through symbiosis. However, it is unknown whether there are differences in the ability of biological nitrogen fixation (BNF) among pulse species and individual cultivars. Here, we quantified the BNF ability of selected pulse cultivars and determined the effect on crop yield. A total of 25 species-cultivar combinations of chickpea (Cicer arietinum L.), dry bean (Phaseolus vulgaris L.), faba bean (Vicia faba L.), field pea (Pisum sativum L.), and lentil (Lens culinaris Medik.) were tested in 2008-2010. Pulses had a higher BNF in the wetter 2010 season, and a lower BNF in the drier 2009 season. In 2010, faba bean and chickpea had the highest BNF at 106 kg N ha −1 , followed by lentil, field pea, and dry bean at 87, 69, and 12 kg N ha −1 , respectively. Across years, field pea had the most stable BNF ability, fixing 55 kg N ha −1 with an average seed yield of 2418 kg ha −1. There are large differences in BNF and yield among cultivars within a species and the magnitude of the difference varied with years. Large genetic variability in BNF and yield suggest the possibility that pulse cultivars with a higher N 2-fixing ability and seed yield can be developed through selection of the N 2-fixing trait.

“…After reviewing the literature, Walley et al (2007) reported that the median value of total plant N derived from the atmosphere was 88% for faba bean, 60% for lentil, and 55% for field pea crops grown in the northern Great Plains region of North America. Little or no N fertilizer is required during their growth phase, and subsequent crops are able to access greater soil mineral N thereby increasing yields and (or) reducing fertilizer N requirements (Soon and Arshad 2004;Tanaka et al 2007). Largely due to reduced fertilizer N inputs, N 2 O emissions during the pulse phase of cropping sequences appear to have substantively lower N 2 O emissions compared with the fertilized phases of the cropping system (Lemke et al 2007;Dusenbury et al 2008;Jeuffroy et al 2013).…”

Effect of crop and residue type on nitrous oxide emissions from rotations in the semi-arid Canadian prairies

et al. 2018

Crop rotations on the Canadian prairies commonly include sequences of pulses, oilseeds, and cereals; however, limited information is available regarding the influence that different crop types and sequences may have on direct nitrous oxide (N2O) emissions. A 3 yr field study was conducted on a site near Scott, SK, to compare N2O emissions from selected crop phases of rotations containing pea (Pisum sativum L.), wheat (Triticum aestivum L.), and canola (Brassica napus L.) and to examine the potential influence of these residues on N2O emissions during the subsequent crop phase. Nitrous oxide losses from N-fertilized canola or wheat crops were generally higher than losses from pea or the control treatments. Nitrous oxide losses from N-fertilized wheat or canola crops grown on pea residue were comparable or lower than losses from N-fertilized wheat or canola crops grown on wheat residues. Cumulative N2O loss over the 3 yr was significantly higher from N-fertilized wheat grown on canola compared with pea or wheat residues. Losses from wheat grown on canola residue were 67% and 56% higher than from wheat grown on pea or wheat residue, respectively. This indicates that the emission factors used to estimate direct N2O loss may need to be adjusted upwards for N-fertilized crops grown on canola compared with wheat or pea residues.
