“…As with biomass N, N supplied by pea may have increased annualized grain N removal in D-C-D-P, D-D-C-P, and D-F-D-P in the ecological and traditional practices. Increased biomass and grain N uptake with crop rotations containing pea with spring wheat and barley compared with continuous spring wheat and barley have been reported by several researchers (Lenssen et al, 2007b;Sainju et al, 2013Sainju et al, , 2015.…”

A B S T R A C TNitrogen balance provides a measure of agroecosystem performance and environmental sustainability by taking into accounts of N inputs and outputs and N retention in the soil. The objective of this study was to evaluate N balance based on N inputs and outputs and soil N sequestration after 7 yr in response to five dryland crop rotations (two 4-yr stacked and two 4-yr alternate-year rotations and one monocropping) and two cultural practices arranged in a split-plot design in the northern Great Plains, USA. Stacked. Alternate-year rotations were durum-canola-durum-pea (D-C-D-P) and durum-flax-durum-pea (D-F-D-P). Monocroppping was continuous durum (CD). Cultural practices were traditional (conventional till, recommended seed rate, broadcast N fertilization, and reduced stubble height) and ecological (no-till, increased seed rate, banded N fertilization, and increased stubble height). Total annual N input due to N fertilization, pea N fixation, atmospheric N deposition, crop seed N, and nonsymbiotic N fixation was lower in CD than other crop rotations, regardless of cultural practices. Total N output due to crop grain N removal and N losses due to denitrification, volatilization, plant senescence, N leaching, gaseous N (NO for ecological D-D-F-P to 52 kg N ha À1 yr À1 for ecological CD. Nitrogen balance ranged from À39 to À36 kg N ha À1 yr À1 with CD compared to 9-25 kg N ha À1 yr À1 with other crop rotations in both cultural practices. Because of reduced reliance on external N inputs and increased grain N removal, N flow, and N surplus, crop rotations with legumes, nonlegumes, and oilseed crops in the rotation can be productive and environmentally sustainable compared with monocropping, regardless of cultural practices.

“…The amount of N fertilizer was relatively lower in NTB‐P than in CTBN and NTBN due to additional N supplied by pea residue. Pea, being a legume with higher N concentration or lower C/N ratio, decomposes more rapidly than malt barley, a nonlegume, and therefore increases soil mineral N content, which reduces the N fertilization rate to succeeding crops (Mosier et al, 2006; Sainju et al, 2013). As a result, CO 2 emissions due to N fertilization was lower in NTB‐P than in CTB‐N and NTB‐N.…”

Little information exists about how global warming potential (GWP) is affected by management practices in agroecosystems. We evaluated the effects of irrigation, tillage, crop rotation, and N fertilization on net GWP and greenhouse gas intensity (GHGI or GWP per unit crop yield) calculated by soil respiration (GWP and GHGI) and organic C (SOC) (GWP and GHGI) methods after accounting for CO emissions from all sources (irrigation, farm operations, N fertilization, and greenhouse gas [GHG] fluxes) and sinks (crop residue and SOC) in a Lihen sandy loam from 2008 to 2011 in western North Dakota. Treatments were two irrigation practices (irrigated vs. nonirrigated) and five cropping systems (conventional-till malt barley [ L.] with N fertilizer [CTBN], conventional-till malt barley with no N fertilizer [CTBO], no-till malt barley-pea [ L.] with N fertilizer [NTB-P], no-till malt barley with N fertilizer, and no-till malt barley with no N fertilizer [NTBO]). While CO equivalents were greater with irrigation, tillage, and N fertilization than without, NO and CH fluxes were 2 to 218 kg CO eq. ha greater in nonirrigated NTBN and irrigated CTBN than in other treatments. Previous year's crop residue and C sequestration rate were 202 to 9316 kg CO eq. ha greater in irrigated NTB-P than in other treatments. Compared with other treatments, GWP and GWP were 160 to 9052 kg CO eq. ha lower in irrigated and nonirrigated NTB-P. Similarly, GHGI and GHGI were lower in nonirrigated NTB-P than in other treatments. Regardless of irrigation practices, NTB-P may lower net GHG emissions more than other treatments in the northern Great Plains.

“…The N:P ratio of YR3 barley was higher in plus-N canola controls than in the YR1 faba bean and pea treatments in 3 of 4 site-years (Table 10). Studies of malt barley have shown that malt barley grain yield, protein concentration, N uptake and biomass increase as N fertilizer rates increase (O'Donovan et al 2011;Sainju et al 2013). O'Donovan et al (2011) noted that malt barley varieties vary in their response to N rate, and increase in protein concentration in response to N rate was more pronounced with AC Metcalfe than with CDC Copeland.…”

. 2015. The effects of three pulse crops on a second subsequent crop. Can. J. Plant Sci. 95: 779Á786. Pulse crops can provide benefits to cropping systems, but few studies follow the effects beyond one subsequent crop. This study investigated the effects of three pulses on 2 yr of subsequent crops at Barrhead and St. Albert in central Alberta. In year 1 (YR1), field pea (Pisum sativum L.), faba bean (Vicia faba L.), lupin (Lupinus angustifolius L.), barley (Hordeum vulgare L.), and canola (Brassica napus L.) were grown without added N. The design included plus N controls, eight different crops in YR2, and barley in YR3. YR1 effects on YR3 barley varied between sites and years, and drought conditions in 2009 affected results. Effects of YR1 faba bean were greater than pea or lupin. Increases in YR3 barley grain yields averaged 11% (0.33 Mg ha(1 ) and increases in seed N yields averaged 11% (7.2 kg N ha (1 ) after YR1 faba bean, compared with after YR1 canola or barley without added N (BCO). Increases in YR3 barley grain yields and seed N yields averaged 3 to 5% after YR1 pea or lupin, compared with BCO.YR1 crops had few effects on YR3 barley P uptake. Results indicated that pulse crops can improve the yield and quality of a second subsequent crop. Re´percussions de trois le´gumineuses sur la culture deux ans plus tard. Can. J. Plant Sci. 95: 779Á786. Les le´gumineuses profitent aux productions agricoles, mais peu d'e´tudes se sont inte´resse´es a`leurs re´percussions au-dela`de la culture subse´quente. Les auteurs ont e´tudie´les conse´quences de la culture de trois le´gumineuses sur les deux anne´es de culture subse´quentes a`Barrhead et a`St. Albert, dans le centre de l'Alberta. La premie`re anne´e, ils ont cultive´du pois (Pisum sativum L.), de la fe`verole (Vicia faba L.), du lupin (Lupinus angustifolius L.), de l'orge (Hordeum vulgare L.) et du canola (Brassica napus L.) sans application d'engrais N. L'expe´rience incluait des te´moins avec application d'engrais N, huit cultures diffe´rentes la deuxie`me anne´e et la culture d'orge la troisie`me. Les effets de la premie`re anne´e de culture sur l'orge cultive´e la troisie`me anne´e varient avec le site et l'anne´e; en outre, la se´cheresse survenue en 2009 a affecte´les re´sultats. La fe`verole cultive´e la premie`re anne´e a eu plus de re´percussions que le pois ou le lupin. Le rendement grainier de l'orge cultive´e la troisie`me anne´e a enregistre´une hausse moyenne de 11 % (0,33 Mg par hectare) tandis que la hausse moyenne du rendement N des semences s'e´levait a`11 % (7,2 kg de N par hectare) apre`s la culture de fe`verole plutoˆt que celle de canola ou d'orge sans apport d'engrais la premie`re anne´e. Apre`s la culture de pois ou de lupin la premie`re anne´e, le rendement grainier et le rendement en N des semences d'orge la troisie`me anne´e avaient augmente´de 3 a`5 % en moyenne, comparativement aux re´sultats obtenus apre`s la culture d'orge sans amendement azote´, la premie`re anne´e.
