Abstract

CONTEXT

The improvement and utilization of desertified soil are essential for global food security. Advances in modern agricultural technology have made it possible to conduct dairy farming on desertified soils.

OBJECTIVE

To clarify the process of desertified soil improvement through a crop and livestock integration agricultural model, and further elucidate the carbon foot print (CF) during this process by a case study.

METHOD

A 15-year study (2008–2023) was conducted on a crop and livestock integration dairy farm to assess soil improvement. Life cycle assessment methodology was employed to analyze the changes in the CF with the increased production capacity of the farm.

RESULT AND CONCLUSIONS

The results revealed the following from 2008 to 2023: (1) soil production increased dramatically, (2) soil organic matter, total nitrogen, available phosphorus, and available potassium improved by 174.7 %, 55.8 %, 241.2 %, and 180.1 %, respectively, (3) unaggregated soil decreased from 77.06 % to 32.03 %, while bulk density decreased from 1.73 to 1.36, and (4) the CF of fat- and protein-corrected milk (FPCM) decreased from 39.72 kg CO₂-eq kg⁻¹ in 2012 to 2.59 kg CO₂-eq kg⁻¹ in 2020, followed by 35 % increase from 2020 to 2023.

SIGNIFICANCE

This study has significant implications for developing sustainable dairy farming systems in desertified areas, focusing on soil productivity improvement and CF reduction.

奶牛养殖业给沙漠化的土地带来了什么？案例研究

荒漠化土壤的改善和利用对全球粮食安全至关重要。现代农业技术的进步使在沙漠化的土壤上进行奶牛养殖成为可能。目的通过农畜一体化农业模式明确沙化土壤改良的过程，并通过案例进一步阐明这一过程中的碳足迹（CF）。方法对一个作物与牲畜一体化的奶牛场进行了一项为期15年（2008-2023）的研究，以评估土壤改善情况。采用生命周期评价方法，分析CF随养殖场生产能力的增加而发生的变化。结果与结论2008 - 2023年的研究结果如下：(1)土壤生产急剧增加,(2)土壤有机质,全氮,磷,钾和可用提高了174.7%,55.8%,241.2%,和180.1%,分别为(3)未聚合的土壤从77.06%下降到32.03%,而体积密度从1.73下降到1.36,和(4)脂肪的CF - protein-corrected牛奶(FPCM)从2012年的39.72公斤CO2-eq公斤−1下降到2.59公斤CO2-eq公斤−1 2020年,从2020年到2023年增长35%。本研究对荒漠化地区发展可持续的奶牛养殖系统具有重要意义，重点是提高土壤生产力和减少CF。

期刊介绍： Agricultural Systems is an international journal that deals with interactions - among the components of agricultural systems, among hierarchical levels of agricultural systems, between agricultural and other land use systems, and between agricultural systems and their natural, social and economic environments. The scope includes the development and application of systems analysis methodologies in the following areas: Systems approaches in the sustainable intensification of agriculture; pathways for sustainable intensification; crop-livestock integration; farm-level resource allocation; quantification of benefits and trade-offs at farm to landscape levels; integrative, participatory and dynamic modelling approaches for qualitative and quantitative assessments of agricultural systems and decision making; The interactions between agricultural and non-agricultural landscapes; the multiple services of agricultural systems; food security and the environment; Global change and adaptation science; transformational adaptations as driven by changes in climate, policy, values and attitudes influencing the design of farming systems; Development and application of farming systems design tools and methods for impact, scenario and case study analysis; managing the complexities of dynamic agricultural systems; innovation systems and multi stakeholder arrangements that support or promote change and (or) inform policy decisions.
