Abstract Environmental issues surrounding conventional annual biogas crops have led to growing interest in alternative crops, such as miscanthus. In addition the better environmental performance, miscanthus can be grown on marginal land where no competition with feed and food is anticipated. On however, biomass yields are significantly lower than good agricultural land. This raises question of economic sustainability cultivated for production. study assessed performance production by...
Abstract The 8,000 biogas plants currently in operation Germany are mainly fed with biomass from annual crops. However, feedstock perennial crops such as miscanthus is expected to be more environmentally benign. If used greater amounts a substrate for anaerobic digestion, storage will become relevant topic, continuous supply of throughout the year necessary. objective this study was identify harvest time that best balances simultaneous achievement high silage quality, digestibility and...
Abstract The suitability of miscanthus biomass for anaerobic digestion has already been confirmed by several studies. However, it is rarely used as feedstock in biogas plants, mainly due to uncertainty about the optimal harvest regime with regard long‐term methane hectare yield and resilience crop green cutting. recommended green‐cut date only commercially available genotype Miscanthus × giganteus ( M×g ) ranges from September November. This timeframe too broad agricultural practice needs be...
Miscanthus is one of the most promising perennial herbaceous industrial crops worldwide mainly due to its high resource-use efficiency and biomass yield. However, extent miscanthus cultivation across Europe still lagging far behind real potential. Major limiting factors are initial costs low yields in crop establishment period, especially first year. This study explores possibility establishing under maize generate from year onwards. A field trial with mono-cropped two procedures, ‘under...
Abstract Carbon neutrality in the transport sector is a key challenge for growing bioeconomy as share of biofuels has stagnated over past decade. This can be attributed to basic economics and lack robust market these technologies. Consequently, more sustainable biomass supply concepts are required that reduce negative impacts on environment at same time promote environmental services agricultural cropping systems including erosion prevention, soil fertility improvement, greenhouse gas...
When heavy metal contaminated soils are excluded from food production, biomass crops offer an alternative commercial opportunity. Perennial have potential for phytoremediation. Whilst the conditions at sites challenging, successful phytoremediation would bring significant economic and social benefits. Seed-based Miscanthus hybrids were tested alongside clone × giganteus on arable land, with Pb, Cd Zn near Katowice. Before randomized experimental plots established (25m2 plant density 2/m2)...
Abstract The bioeconomy, with its aim of replacing fossil by biobased resources, is increasingly focusing on biomass production from perennial crops, such as miscanthus. To date, research miscanthus has explored a number cultivation aspects; however, one major issue not yet been addressed: How can former fields be reintegrated into crop rotation? This encompasses the questions which following most efficiently suppresses resprouting and what happens to soil nitrogen content after removal....
This study reports on the effects of two rhizome-based establishment procedures ‘miscanthus under maize’ (MUM) and ‘reference’ (REF) methane yield per hectare (MYH) miscanthus in a field trial southwest Germany. The dry matter (DMY) aboveground biomass was determined each year autumn over four years (2016–2019). A biogas batch experiment fiber analysis were conducted using plant samples from 2016–2018. Overall, MUM outperformed REF due to high MYH maize 2016 (7211 m3N CH4 ha−1)....
Abstract The demand for perennial nonfood crops, such as miscanthus, is increasing steadily, fossil resources are replaced by biomass. However, the establishment of miscanthus very expensive, its cultivation area in Europe still small. most common propagation method via rhizomes, harvesting which labour‐intensive. Seed promising, but not suitable sterile genotypes. In this study, a new vegetative method, ‘collar propagation’, was tested field and controlled environment studies. Collars built...
Abstract Harvest time is an important variable that determines the yield of miscanthus biomass, its possible end uses, and nutrient offtake from field. Green harvests result in a higher greater removal Brown harvests, carried out late winter or early spring, lower yields offtake, whereby harvested biomass better suited to use combustion. To look at long‐term impact green on miscanthus, this experiment followed development two hybrids subjected brown over period seven years one site Southern...
