“…Previous experiments [50] confirmed the research results of Forleo et al [42]. Both the choice of fertilizer type [51] and fertilization management [52] have significant implications in the environmental impacts. There is a large amount of published LCA studies of OSR cultivation, especially about feedstock for biofuels production.…”

“…The primary factors causing variability in OSR pod strength are genetic traits, moisture, stage of ripeness, physical condition of the canopy, and environmental conditions [12]. Most studies use the opening force measurement to evaluate the genetic basis of spontaneous pod shattering resistance in varieties [14,51,65,66] or to determine effects of fertilizer use and growing conditions on pod strength [67]. No study has evaluated the effectiveness of pod sealant in reducing losses due to pod shattering by measuring the force needed to separate OSR pod valves.…”

Shattering of pods of oilseed rape (Brassica napus L.) is a major cause of seed yield losses prior to and during harvesting. In order to reduce shattering, researchers have been engaged in the development of special preparations that are known as pod sealants (PS). Despite the fact that there are already developed and commercialized PSs that have only been effective on seed yield preservation under certain environmental conditions, there is still a need to create a more versatile and efficient PS. Currently, the most promising method of controlling pod shattering in oilseed rape is the application of our developed novel acrylic- and trisiloxane-based pod sealant (PS4). The effectiveness of PS4 and three commercial pod sealants (PS1, PS2, and PS3) was assessed in this comparative study. By spraying an oilseed rape crop with PS4, natural seed loss can be reduced by 20–70%, depending on the prevailing weather conditions, and loss of seeds during harvest can be reduced by more than three-fold compared with that by the control treatment. Thus, the overall results demonstrated that by applying a novel pod sealant (PS4) to oilseed rape crops 2 weeks before harvest can increase the net profit margin by €30–€150 ha−1. The life cycle assessment showed that during 2014–2016 oilseed rape cultivation, the largest effect on global warming emission (kg CO2 eq) reduction was experimental sealant PS4, i.e., approximately 17% compared to the control.

“…A major crop for biofuel production in the EU is oilseed rape ( Brassica napus L.), where the seeds are converted to biodiesel in the form of rapeseed methyl ester (EUBIA, ). For this crop, it has been estimated that direct emissions of nitrous oxide (N 2 O) in the field represent 33%–55% of total GHGs from the cultivation step as calculated in carbon dioxide (CO 2 ) equivalents, CO 2eq (Elsgaard, Olesen, Hermansen, Kristensen, & Børgesen, ; Malça, Coelho, & Freire, ; Queirós, Malça, & Freire, ). Such estimates are typically based on the IPCC default Tier 1 emission factor (EF), whereby it is assumed that 1% of the nitrogen (N) introduced in fertilizers and crop residues will be emitted as N 2 O‐N (IPCC, ).…”

DMPP reduced nitrification, but not annual N₂O emissions from mineral fertilizer applied to oilseed rape on a sandy loam soil

Direct field emissions of nitrous oxide (N2O) may determine whether biodiesel from oilseed rape (Brassica napus L.) fulfills the EU requirement of at least 50% reduction of greenhouse gas emissions as compared to fossil diesel. However, only few studies have documented fertilizer N emission factors (EF) and mitigation options for N2O emissions from oilseed rape cropping systems. We conducted a field experiment with three N levels (0, 171, and 217 kg/ha), where the N fertilizer was applied as ammonium sulfate nitrate with or without the nitrification inhibitor 3,4‐dimethylpyrazole phosphate (DMPP). N2O fluxes were measured using static chambers technique and soil samples were analyzed for water and mineral N content during a monitoring period of 368 days. The DMPP treatments showed a significantly increased level of ammonium (NH4+) for up to 18 weeks after spring fertilization as compared to the treatments without DMPP. However, this difference did not result in a corresponding decrease in NO3- soil content, and no differences in cumulative N2O emissions were found between any fertilized treatments with or without DMPP (mean, 1.26 kg N2O‐N ha−1 year−1). More field experiments are needed to clarify whether DMPP‐coated mineral fertilizers could mitigate N2O emissions under different weather conditions, for example, under conditions where fertilization events concurred with rainfall events increasing water‐filled pore space to the assumed 60% threshold for denitrification. Emission factors for mineral N fertilizer were 0.28%–0.36% with a mean of 0.32% across the fertilized treatments. These data concur with recent European studies suggesting that the EF for mineral N fertilizers in oilseed rape cropping systems may typically be lower than the default IPCC value of 1%. Further studies are needed to consolidate an EF for oilseed rape under temperate conditions, which will be determining for the sustainability of Northern European oilseed rape cultivation for biodiesel.
