“…10 The oil obtained from OSR seeds can be used for human consumption, but its global production has increased mainly due to its use to produce biofuel. 11,12 OSR is attacked by multiple insect pests that are managed by intensive use of insecticides (mainly pyrethroids), which has also triggered the widespread pyrethroid resistance in B. aeneus. [13][14][15][16][17] For C. obstrictus, pyrethroid resistance was reported in Poland and Germany.…”

BACKGROUNDAgricultural landscapes provide resources for arthropod pests as well as their natural enemies. To develop integrated pest management (IPM) practices, it is important to understand how spatiotemporal location influences crop colonization and damage severity. We performed a 3‐year (2016–2018) field experiment in winter oilseed rape (OSR, Brassica napus) fields in Estonia, where half of the fields were within 500 m of the location of the previous year's winter OSR field and half were outside this zone. We investigated how distance from the previous year's OSR crop influences the infestation and parasitism rates of two of its most important pests: the pollen beetle (Brassicogethes aeneus) and the cabbage seed weevil (Ceutorhynchus obstrictus).RESULTSWhen the distance from the previous year's OSR crop was >500 m, we recorded significantly reduced pest pressure by both B. aeneus and C. obstrictus in the study fields. Biocontrol of both pests, provided by parasitic wasps, was high in each study year and commonly not affected by distance. Mean parasitism rates of B. aeneus were >31%, occasionally reaching >70%; for C. obstrictus, mean parasitism was >46%, reaching up to 79%, thereby providing effective biocontrol for both pest species.CONCLUSIONSpatiotemporal separation of OSR fields can reduce pest pressure without resulting in reduced parasitism of OSR pests. This supports a spatiotemporal field separation concept as an effective and sustainable technique for IPM in OSR.

“…A high oil yield per acre makes canola and rapeseed ideal for biodiesel production. In addition, biodiesel made from canola and rapeseed oil has excellent quality characteristics, mainly improved cold flow, longer shelf life, and reduced mono-nitrogen oxides (NOx) emissions compared with other feedstock oils (Brown, 2010;Zhang and Malhi, 2010).…”

Effect of replacing solvent-extracted canola meal with high-oil traditional canola, high-oleic acid canola, or high-erucic acid rapeseed meals on rumen fermentation, digestibility, milk production, and milk fatty acid composition in lactating dairy cows

The objective of this experiment was to investigate the effects of replacing conventional, solvent-extracted canola meal (control; CTRL) with high oil content; conventional, mechanically extracted canola meal (CMEC); high-oleic, low polyunsaturated fatty acid (FA) canola meal (HOLL); and high-erucic acid, low-glucosinolate rapeseed meal (RPS) on rumen function, digestibility, milk production, and milk FA composition in lactating dairy cows. The experimental design was a replicated 4×4 Latin square with 8 lactating dairy cows. Four of the cows were ruminally cannulated. All oilseed meals were included at approximately 12 to 13% of dietary dry matter (DM). Crude protein and fat concentrations (% of DM) of the meals were 43 and 3.1%, 32.8 and 16.1%, 45.2 and 13.7%, and 34.3 and 17.9% for CTRL, CMEC, HOLL, and RPS, respectively. All diets were formulated to supply net energy of lactation in excess of requirements. The CMEC and RPS diets were predicted to be about 1% deficient in metabolizable protein. Relative to the CTRL, inclusion of high-oil seed meals in the diet lowered ruminal acetate concentration and the molar acetate:propionate ratio and decreased DM intake. Milk yield generally followed DM intake and was lower for CMEC and RPS than the CTRL. Treatments had no effect on milk composition, other than an increase in milk urea nitrogen concentration for HOLL. Fat-corrected milk (3.5%) feed efficiency was increased by HOLL and RPS compared with CTRL. Urinary urea nitrogen losses were increased by HOLL, which, as a consequence, increased the ammonia-emitting potential of manure. The ratio of milk N-to-N intake was greater for CMEC and RPS. Replacing solvent-extracted canola meal with the high-oil meal decreased milk fat 12:0, 14:0, 16:0, and total saturated FA content and enhanced cis-9 18:1 and total monounsaturated FA concentrations. Relative to the CTRL, canola increased total trans FA in milk, whereas inclusion of HOLL in the diet increased trans-11 18:1 and cis-9, trans-11 CLA content. The RPS increased milk fat cis-13 22:1 content from 0.07 to 2.33 g/100g of FA. In conclusion, HOLL or RPS, which are likely to come from small-scale biodiesel plants where oil is cold pressed without hexane extraction, fed at levels at or above 12 to 13% of dietary DM may decrease feed intake and milk production, but can be used to alter milk FA composition in lactating dairy cows.

“…There were no significant effects of plantation age on soil organic matter, microbial biomass, potential soil respiration, or solid surface CO 2 flux, implying soil C was in dynamic equilibrium over a relatively long (11-54 years) period since planting. However, the short-term C sink may significantly increase in root biomass with plantation age [100]. Although it can be produced in an environmentally friendly manner to help mitigate global climate change and preserve biodiversity, oil palm, as it is currently practiced, contributes to GHG emissions, impacts local environments, and replaces important C sinks in peat lands [20,95].…”

“…Soil resources play an important role in global climate change processes due to their function as sinks and sources of GHGs [100,250]; however, they represent a massive stock of potentially unstable C [206], acting as a buffer against atmospheric CO 2 increase and as a potential sink for additional C. The buffering capacity depends on the balance between photosynthesis, decomposer activity, and C sequestration [206]. Deforestation, responsible for 30% of the anthropogenic increase in atmospheric [CO 2 ] over the past 200 years, is considered as the leading threat to the terrestrial C sink [31,60,255,259].…”

Different forms of carbon (C) cycle continuously through several pools in natural and managed ecosystems and spheres. Carbon's recent "commodification," as a negative environmental externality, has rendered it a "scarce" and "tradable" element. Although C supply in nature is not limited, energy is required to make it available as a plant nutrient, assimilate it in plant tissues, and sequester it as temporary or recalcitrant C in soils. Human demand for C-based energy and plantfixed C has accelerated, and altered its global cycle, raised its atmospheric content, contributed to climate change through global warming, and impacted several provisioning, regulating, and supporting ecosystem services. Agroecosystems are both sources and sinks of C. In a carbon dioxide-constrained world, plant-fixed and sequestered C in natural and managed ecosystems has a potential role in mitigating climate change, providing C-neutral and renewable bioenergy, and positively affecting ecosystem services. Due to the intricacies of the complex, interconnected biogeochemical cycles involving C, nitrogen, and water in which soils play an important role, bioenergy crops do not provide an easy solution to climate change mitigation, they may contribute to it. This chapter presents a critical review assessing the state of knowledge, and exploring opportunities and challenges of the role of C in bioenergy crops in mitigating global climate change, while sustainably providing other ecosystem services.
