POLICIES AND REGULATIONS FOR PROMOTING MANURE MANAGEMENT FOR SUSTAINABLE LIVESTOCK PRODUCTION IN CHINA

Sha WEI, Zhiping ZHU, Jing ZHAO, David R. CHADWICK, Hongmin DONG

《农业科学与工程前沿（英文）》 2021年 第8卷 第1期   页码 45-57 doi: 10.15302/J-FASE-2020369

摘要： Livestock numbers in China have more than tripled between 1980 and 2017. The increase in the number of intensive livestock production systems has created the challenges of decoupled crop and livestock systems, low utilization of manures in croplands, and subsequent environmental pollution. Correspondingly, the government has enacted a series of policies and regulations to increase the sustainability of livestock production. This paper reviews the objectives of these policies and regulations and their impacts on manure management. Since 2017 there have been two policy guides to speed up the appropriate use of manures, three action plans for increasing manure recycling, and one technical guide to calculate nutrient balances. Requirements of manure pollution control and recycling for improved environmental performance of livestock production systems were included in three revised environmental laws. Most recent survey data indicate that the utilization of livestock manures was 70% in 2017, including that used as fertilizer and/or for production of energy. The targets for manure utilization are 75% in 2020 and 90% in 2035. To achieve these targets and promote ‘green livestock production’, additional changes are needed including the use of third-party enterprises that facilitate manure exchange between farms and a more integrated manure nutrient management approach.

贾伟,臧建军,张强,李德发

《中国工程科学》 2017年 第19卷 第4期   页码 130-137 doi: 10.15302/J-SSCAE-2017.04.021

摘要：

本文介绍我国畜禽养殖废弃物还田利用模式发展概况，分析养殖废弃物循环利用产业发展的问题，探讨下一步的发展战略。总结发现，多年来国内外在探索畜禽养殖废弃物还田利用模式、农田适宜载畜量参数等方面取得了重要的进展，但仍然存在种养结合养分不平衡、各种处理过程养分损失大、农田合理施用粪肥原则缺失等问题。下一步的研究应该以“还田利用，环境友好”为目标，引入种养结合粪便养分管理理念，开展畜禽养殖废弃物的收集—贮存—处理—还田；开展包括优化还田安全利用技术、种养循环过程温室气体减排、农田对养殖废弃物合理消纳量定量、减少氮磷养分损失避免面源污染等方面的研究，同时在政策上引导畜禽养殖废弃物的高效资源化利用。

POLICIES AND REGULATIONS FOR PROMOTING MANURE MANAGEMENT FOR SUSTAINABLE LIVESTOCK PRODUCTION IN CHINA

《农业科学与工程前沿（英文）》 2021年 第8卷 第1期

摘要：

• Manure utilization is hindered by separate specialist crop and livestock production systems.

• Improving manure utilization requires organizations for manure exchange.

• Policies and action plans for improving manure utilization are critically reviewed.

• A manure chain approach with third-party contractors is recommended.

 

Livestock numbers in China have more than tripled between 1980 and 2017. The increase in the number of intensive livestock production systems has created the challenges of decoupled crop and livestock systems, low utilization of manures in croplands, and subsequent environmental pollution. Correspondingly, the government has enacted a series of policies and regulations to increase the sustainability of livestock production. This paper reviews the objectives of these policies and regulations and their impacts on manure management. Since 2017 there have been two policy guides to speed up the appropriate use of manures, three action plans for increasing manure recycling, and one technical guide to calculate nutrient balances. Requirements of manure pollution control and recycling for improved environmental performance of livestock production systems were included in three revised environmental laws.

EXPLORING THE RECYCLING OF MANURE FROM URBAN LIVESTOCK FARMS: A CASE STUDY IN ETHIOPIA

《农业科学与工程前沿（英文）》 2021年 第8卷 第1期

摘要：

• Livestock manure was the main organic waste in urban and peri-urban areas.

• Manure production will increase by a factor of 3–10 between 2015–2050.

• Only 13%–38% of excreted N by livestock will be recycled in croplands.

• Intensification of urban livestock production greatly increased N surpluses.

• Reducing population growth and increasing livestock productivity needed.

 

Urban population growth is driving the expansion of urban and peri-urban agriculture (UPA) in developing countries. UPA is providing nutritious food to residents but the manures produced by UPA livestock farms and other wastes are not properly recycled. This paper explores the effects of four scenarios: (1) a reference scenario (business as usual), (2) increased urbanization, (3) UPA intensification, and (4) improved technology, on food-protein self-sufficiency, manure nitrogen (N) recycling and balances for four different zones in a small city (Jimma) in Ethiopia during the period 2015-2050. An N mass flow model with data from farm surveys, field experiments and literature was used. A field experiment was conducted and N use efficiency and N fertilizer replacement values differed among the five types of composts derived from urban livestock manures and kitchen wastes. The N use efficiency and N fertilizer replacement values were used in the N mass flow model.

Livestock manures were the main organic wastes in urban areas, although only 20 to 40% of animal-sourced food consumed was produced in UPA, and only 14 to 19% of protein intake by residents was animal-based. Scenarios indicate that manure production in UPA will increase 3 to 10 times between 2015 and 2050, depending on urbanization and UPA intensification. Only 13 to 38% of manure N will be recycled in croplands. Farm-gate N balances of UPA livestock farms will increase to>1 t·ha−1 in 2050. Doubling livestock productivity and feed protein conversion to animal-sourced food will roughly halve manure N production.

Costs of waste recycling were high and indicate the need for government incentives. Results of these senarios are wake-up calls for all stakeholders and indicate alternative pathways.

INTEGRATED CROP-LIVESTOCK SYSTEMS: LESSONS FROM NEW YORK, BRITISH COLUMBIA, AND THE SOUTH-EASTERN UNITED STATES

Alan FRANZLUEBBERS, Derek HUNT, Gary TELFORD, Shabtai BITTMAN, Quirine KETTERINGS

《农业科学与工程前沿（英文）》 2021年 第8卷 第1期   页码 81-96 doi: 10.15302/J-FASE-2020365

摘要： Livestock production in the United States (US) and Canada is diverse, but shows a common trend in most livestock sectors toward fewer farms producing the majority of animal products despite a large number of farms still small in production scale. The migration to larger and more concentrated animal feeding operations in beef finishing and poultry, swine, and dairy production allows processors to streamline supplies to meet market demand for abundant, low-cost livestock products, whether that be for packaged meat, dairy products, or eggs. With concentration of livestock operations comes the challenge of managing manures. When sufficient land is available and nutrients are needed, livestock manure is an excellent nutrient source and land application is the preferred method of recycling this resource. However, when livestock production is constrained in a geographical area and animal densities are high, manure may become an environmental liability with potentially greater risk for runoff and leaching of nutrients, emission of odors, ammonia, and greenhouse gases, and release to the environment of pathogens and chemicals of emerging concern. Addressing these challenges now and into the future requires learning from mistakes and adopting successful approaches. We describe different levels of integration between livestock and crop producers in New York, British Columbia, and the south-eastern US as learning opportunities to improve economic and environmental sustainability. Examples show that effective solutions should recognize (1) manure has value and is not just a cost, (2) farmers, farm advisors, extension educators, nutrient management planners, crop advisors, nutritionists, state agency personnel, regulators, and university researchers need to be active participants in development of solutions, and (3) change to a sustainable future requires a combination of government regulation and outcome-based incentives.

The speciation, leachability and bioaccessibility of Cu and Zn in animal manure-derived biochar: effect

Qi Lin, Xin Xu, Lihua, Wang, Qian Chen, Jing Fang, Xiaodong Shen, Liping Lou, Guangming Tian

《环境科学与工程前沿（英文）》 2017年 第11卷 第3期 doi: 10.1007/s11783-017-0924-8

摘要： Biochars derived from animal manures may accumulate potentially toxic metals and cause a potential risk to ecosystem. The synchrotron-based X-ray spectroscopy, sequential fractionation schemes, bioaccessibility extraction and leaching procedure were performed on poultry and swine manure-derived biochars (denoted PB and SB, respectively) to evaluate the variance of speciation and activity of Cu and Zn as affected by the feedstock and pyrolysis temperature. The results showed that Cu speciation was dependent on the feedstock with Cu-citrate-like in swine manure and species resembling Cu-glutathione and CuO in poultry manure. Pyrolyzed products, however, had similar Cu speciation mainly with species resembling Cu-citrate, CuO and CuS/Cu S. Organic bound Zn and Zn (PO ) -like species were dominant in both feedstock and biochars. Both Cu and Zn leaching with synthetic precipitation leaching procedure (SPLP) and toxicity characteristic leaching procedure (TCLP) decreased greatly with the rise of pyrolysis temperature, which were consistent with the sequential extraction results that pyrolysis converted Cu and Zn into less labile phases such as organic/sulfide and residual fractions. The potential bioaccessibility of Zn decreased for both the PB and SB, closely depending on the content of non-residual Zn. The bioaccessibility of Cu, however, increased for the SB prepared at 300°C–700°C, probably due to the increased proportion of CuO. Concerning the results of sequential fractionation schemes, bioaccessibility extraction and leaching procedure, pyrolysis at 500°C was suggested as means of reducing Cu/Zn lability and poultry manure was more suitable for pyrolysis treatment.

Greenhouse gas emissions during co-composting of cattle feedlot manure with construction and demolition

Xiying Hao, Francis J. Larney

《环境科学与工程前沿（英文）》 2017年 第11卷 第3期 doi: 10.1007/s11783-017-0955-1

摘要： Manure management strategies should reflect current animal feeding practices and encourage recycling of organic waste to help protect our environment. This research investigated greenhouse gas (GHG) emissions during cattle manure stockpiling or composting with and without construction and demolition (C&D) waste. Manure was collected from cattle fed a typical finishing diet (CK manure) and from cattle on diets which included 30% dried distillers grains with solubles (DG manure). The CK and DG manures were co-composted with (4:1) C&D waste (treatments: CK_CD DG_CD), composted alone (treatments: CK and DG) in 13 m bins or stockpiled without C&D waste (treatments: CK_ST and DG_ST) for 99 days. Manure type (CK vs. DG manure) had no effect on GHG emissions over the 99 day manure composting or stockpiling. Composting with C&D waste produced similar CO emissions, about double that from manure stockpiling (7.0 kgC·m ). In contrast, CH emissions were reduced by the inclusion of C&D waste (64 gC·m with C&D vs. 244 gC·m without C&D) while the manure stockpile emitted the greatest amount of CH (464 gC·m ). Additionally, only 0.48% of C was emitted in CH form with C&D waste, compared to 1.68% when composting without C&D waste and 7.00% when cattle manure was stockpiled. The N O emissions (12.4 to 18.0 gN·m ) were similar across all treatments. The lower CH emissions with C&D waste are beneficial in reducing overall GHG emissions from manure composting, while reducing the amount of material entering landfills.
