2 Managing Crop Residue. Crop residue is a resource to conserve and use. Crop residue is a food source for beneficial fungi, bacteria, and insects, limits evaporation from the soil surface, and maintains water vapor in the soil. Crop producers manage crop residue based on several factors including the crop being planted, soil type, annual
Feb 7, 2020 · Crop residues are cellulosic material having high fixed carbon content, could be a potential source of feedstock for energy generation, and need to be critically and objectively assessed because of its positive impact on soil carbon sequestration, soil quality maintenance, ecosystem functions, etc.
The valorization of Jerusalem artichoke (JA) and its crop residues using environment-friendly green technologies, including enzymatic hydrolysis, fermentation, extraction, and biorefinery processes, is sustainable and efficient in converting into valuable products. Enzymatic hydrolysis of residual biomass yields sugars, serving as feedstock for
Sep 20, 2022 · Lactic acid (LA) is a chemical building block with wide applications in the food, cosmetics, and chemical industries. Its polymer polylactic acid further increases this range of applications as a green and biocompatible alternative to petrol-based plastics. Corn is the fourth largest crop in the world, and its residues represent a potentially renewable feedstock for industrial lactic acid
Nov 24, 2020 · Crop residues, the byproduct of crop production, are valuable natural resources that can be managed to maximize different input use efficiencies. Crop residue management is a well-known and widely accepted practice, and is a key component of conservation agriculture. The rapid shift from conventional agriculture to input-intensive modern agricultural practices often leads to an increase in the
Feb 1, 2023 · This study estimated the potential BHP from the dark fermentation of typical crop residues and its contribution to China's energy consumption and carbon emission reduction. In 2019, the available crop residue yield (including rice straw, wheat straw, maize straw, yam straw, and bean straw) was 9.2 × 10 8 t/a, and 4.7 × 10 8 t
Sep 1, 2012 · Anaerobic fermentation may significantly enhance the nutrients contents of crop residues (including corn stalks) and decrease fiber content and pH values, leading to increase in cattle digestion rates [35], [36]. In addition, increased palatability and the unique smell of fermented forages might stimulate a cattle's appetite, leading to a
May 3, 2024 · Pretreatment is an important step in the bioconversion of lignocellulosic materials, including crop residues. This Special Issue includes nine articles on several pretreatment and bioconversion approaches applied to different agricultural residues and food-processing by-products.
Apr 21, 2022 · Human-unfit biomass generated in the agri-food systems can be grouped into three broad categories [10]: (i) crop residues upon removal of the edible parts, typically inedible/indigestible; (ii) processing byproducts (or co-products) consisting of the remaining residues from food/beverage processing industries, generally unpalatable; (iii) food
Sep 27, 2021 · There is significant potential to reduce CH 4 from these sources, with bottom-up mitigation potentials of approximately 10.6, 10, 2 and 1 Tg CH 4 y −1 from rice management, enteric fermentation, manure management and residue burning. Other system-wide studies have assumed even higher potentials of 4.8–47.2 Tg CH 4 y −1 from reduced
Apr 1, 2017 · The photo-fermentation bio-hydrogen production system from crop residues with a high concentration of solid phase, high viscosity and low light transmittance needs extensive mixing; a novel reactor design with minimum mixing power input is desired.
Jun 28, 2019 · This study provided an estimate of the potential of bio-hydrogen production from dark fermentation of crop residues on a worldwide scale. The different crop residues reviewed included sugarcane tops, leaves and bagasse, corn straw, corn cob and corn stover, wheat straw, rice straw and husk, soybean straw, oil palm trunk and empty fruit bunch, sugar beet pulp, cassava residue, barley straw and
Jul 11, 2023 · Mulching. Mulching, a natural process, involves leaving crop residues on the field to decompose gradually. By enhancing the soil’s organic matter content, mulching improves its structure and fertility and helps maintain its moisture levels. It also serves as a natural weed suppressant, thus aiding in effective weed management.
Aug 30, 2019 · The current world population of 7.3 billion is for ecasted to reach 10 billion by 2050, for. which the wor ld food demand is expected to double, while meat and milk demand rise up to. 73% and 58%
Jul 15, 2022 · Effects of residual monensin in livestock manure on nitrogen transformation and microbial community during “crop straw feeding-substrate fermentation-mushroom cultivation” recycling system Author links open overlay panel Fei Wang a , Yi Fang a 1 , Lixia Wang a , Hai Xiang a b , Guoshuang Chen a , Xiao Chang a b , Di Liu c , Xinmiao He c
