“…The feedstock used in AD facilities was generally a mixture of animal manure, energy crops, and agricultural residues. The ratios of the inputs were designed to maximise biogas production, based upon the biogas potential of the mixture (Rana et al, 2016;Igos et al, 2016). Nayal et al (2016) highlighted that 70% of biogas plants operating in the EU were installed in farms using agricultural wastes, manure, and energy crops.…”

“…The main objective of this is to reduce erosion and to improve the structure and water retention capacity of the soil (Igos et al, 2016). Furthermore, management of cropping systems with CCs provides benefits related to soil characteristics, such as adding increased humus to the soil, that reduces compaction, improves water holding capacity, improves biological weed and pest control and improves nutrient cycling through reduced leaching and enhanced nitrogen sequestration (Igos et al, 2016).…”

“…Shao et al (2015) showed that fertilizing and harvesting winter rye can increase feedstock supplies and producer revenue compared with unfertilized rye, but N losses to subsurface drainage and net energy potential of the system were not investigated. Studies have addressed various combinations of potential producer revenue, N loss to the environment, and net energy potential of agricultural systems that include harvested winter rye (e.g., Rotz et al, 2002;Igos et al, 2016;Ramcharan and Richard, 2017). But studies are needed that simultaneously address potential producer revenue, N loss to subsurface drainage, and net energy potential of corn-soybean systems in the US Midwest that include harvested and fertilized double-cropped winter rye.…”

Harvesting fertilized rye (Secale cereale L.) cover crop has been suggested as a method to increase producer revenue and biofuel feedstock production, but drainage N loss impacts are currently unknown. Using the tested Root Zone Water Quality Model (RZWQM) across several N rates, spring application of 120 kg N ha -1 prior to winter rye harvest reduced drainage N loss by 54% compared with no cover crop and by 18% compared with planted rye that was neither fertilized nor harvested. Estimates of producer revenue and net energy were also positive, with 8.3 Mg ha -1 of harvested rye biomass. If confirmed by field studies, these results suggest that double-cropping fertilized rye is a promising strategy to increase producer revenue, increase net energy production, and reduce drainage N loss. Core Ideas• Fertilizing winter rye increased estimated revenue and harvestable biomass.• Fertilizing winter rye increased net energy production.• Harvesting fertilized winter rye reduced simulated drainage N loss.• Rye revenue in response to fertilizer rate plateaued at approximately 120 kg N ha −1 .• Field studies are needed to evaluate fertilized/ harvested rye cover crop.Abbreviations: CC, cover crop; CCH, unfertilized harvested cover crop; CCH_L_x, late harvest of fertilized cover crop; DM, dry matter; NCC, no cover crop.

“…Soil response to agronomic methods is also influenced by soil and environmental conditions ( Bescansa et al, 2006 ) in addition to CCs management. The introduction of rye CCs conserved soil resources and had environmental benefits immediately and long-term economic benefits during the cropping system ( Igos et al, 2016 ).…”

Sustainable reduction of fertilization with technology acquisition for improving soil quality and realizing green food production is a major strategic demand for global agricultural production. Introducing legume (LCCs) and/or non-legume cover crops (NLCCs) during the fallow period before planting main crops such as wheat and corn increases surface coverage, retains soil moisture content, and absorbs excess mineral nutrients, thus reducing pollution. In addition, the cover crops (CCs) supplement the soil nutrients upon decomposition and have a green manure effect. Compared to the traditional bare land, the introduction of CCs systems has multiple ecological benefits, such as improving soil structure, promoting nutrient cycling, improving soil fertility and microbial activity, controlling soil erosion, and inhibiting weed growth, pests, and diseases. The residual decomposition process of cultivated crops after being pressed into the soil will directly change the soil carbon (C) and nitrogen (N) cycle and greenhouse gas emissions (GHGs), and thus affect the soil microbial activities. This key ecological process determines the realization of various ecological and environmental benefits of the cultivated system. Understanding the mechanism of these ecological environmental benefits provides a scientific basis for the restoration and promotion of cultivated crops in dry farming areas of the world. These findings provide an important contribution for understanding the mutual interrelationships and the research in this area, as well as increasing the use of CCs in the soil for better soil fertility, GHGs mitigation, and improving soil microbial community structure. This literature review studies the effects of crop biomass and quality on soil GHGs emissions, microbial biomass, and community structure of the crop cultivation system, aiming to clarify crop cultivation in theory.
