“…Philibert et al ( 2012 ) calculated lower emission factors (EF) when the amount of N applied was below 160 kg N ha −1 , Hinton et al ( 2015 ) estimated EF to be between 0.28 and 1.35% of applied N depending on the N input, and Rees et al ( 2012 ) concluded from a meta-analysis using measured data from Europe that annual emissions from arable sites were significantly greater than predicted by IPCC. Besides N fertilizer inputs, field-based nitrous oxide emissions are influenced by soil, management and environmental conditions (Ball et al, 2014 ). It seems clear that the EF used in the present study is approximate, but there is no consensus on how to modify it to better represent actual emissions.…”

Trade-Offs between Economic and Environmental Impacts of Introducing Legumes into Cropping Systems

et al. 2016

Europe's agriculture is highly specialized, dependent on external inputs and responsible for negative environmental impacts. Legume crops are grown on less than 2% of the arable land and more than 70% of the demand for protein feed supplement is imported from overseas. The integration of legumes into cropping systems has the potential to contribute to the transition to a more resource-efficient agriculture and reduce the current protein deficit. Legume crops influence the production of other crops in the rotation making it difficult to evaluate the overall agronomic effects of legumes in cropping systems. A novel assessment framework was developed and applied in five case study regions across Europe with the objective of evaluating trade-offs between economic and environmental effects of integrating legumes into cropping systems. Legumes resulted in positive and negative impacts when integrated into various cropping systems across the case studies. On average, cropping systems with legumes reduced nitrous oxide emissions by 18 and 33% and N fertilizer use by 24 and 38% in arable and forage systems, respectively, compared to systems without legumes. Nitrate leaching was similar with and without legumes in arable systems and reduced by 22% in forage systems. However, grain legumes reduced gross margins in 3 of 5 regions. Forage legumes increased gross margins in 3 of 3 regions. Among the cropping systems with legumes, systems could be identified that had both relatively high economic returns and positive environmental impacts. Thus, increasing the cultivation of legumes could lead to economic competitive cropping systems and positive environmental impacts, but achieving this aim requires the development of novel management strategies informed by the involvement of advisors and farmers.

Trade-Offs between Economic and Environmental Impacts of Introducing Legumes into Cropping Systems

“…Evenness of soil bacterial communities has been associated with functional stability and the resilience to environmental disturbance ( Wittebolle et al, 2009 ), whereas increased species richness has been linked to greater activity (respiration) and resource-use efficiency of microbial communities ( Bell et al, 2005 ; Saleem et al, 2016 ). However, the relationship between soil microbial communities and fertilizer inputs is complex, and some studies have found no difference in bacterial richness or evenness between the two management systems ( Pershina et al, 2015 ). The amount of nitrogen (N) applied to soils has also been reported to impact microbial communities ( Nemergut et al, 2008 ; Ramirez et al, 2010 , 2012 ; Fierer et al, 2012 ), leading to a reduction in soil microbial diversity in some cases ( Li et al, 2016 ).…”

Rhizosphere Bacterial Communities Differ According to Fertilizer Regimes and Cabbage (Brassica oleracea var. capitata L.) Harvest Time, but Not Aphid Herbivory

et al. 2018

Rhizosphere microbial communities are known to be highly diverse and strongly dependent on various attributes of the host plant, such as species, nutritional status, and growth stage. High-throughput 16S rRNA gene amplicon sequencing has been used to characterize the rhizosphere bacterial community of many important crop species, but this is the first study to date to characterize the bacterial and archaeal community of Brassica oleracea var. capitata. The study also tested the response of the bacterial community to fertilizer type (organic or synthetic) and N dosage (high or low), in addition to plant age (9 or 12 weeks) and aphid (Myzus persicae) herbivory (present/absent). The impact of aboveground herbivory on belowground microbial communities has received little attention in the literature, and since the type (organic or mineral) and amount of fertilizer applications are known to affect M. percicae populations, these treatments were applied at agricultural rates to test for synergistic effects on the soil bacterial community. Fertilizer type and plant growth were found to result in significantly different rhizosphere bacterial communities, while there was no effect of aphid herbivory. Several operational taxonomic units were identified as varying significantly in abundance between the treatment groups and age cohorts. These included members of the S-oxidizing genus Thiobacillus, which was significantly more abundant in organically fertilized 12-week-old cabbages, and the N-fixing cyanobacteria Phormidium, which appeared to decline in synthetically fertilized soils relative to controls. These responses may be an effect of accumulating root-derived glucosinolates in the B. oleracea rhizosphere and increased N-availability, respectively.
