Soil Quality Assessment And Management, M. G. Kibblewhite

IGC Proceedings (1997-2023)

Key points

1. Soil quality is related to the capacity of soil to deliver ecosystem services on a sustainable basis.

2. Effective management of soil within grasslands can deliver many benefits to mankind but poor management may cause loss of soil quality from erosion, loss of organic matter, physical deterioration etc.

3. Services are delivered from soil by biological processes. Soil quality depends on the form and condition of the soil habitat. Fixed factors (e.g. texture) are useful for assigning soil to types. Variable factors (e.g. organic carbon) can then be used to assess quality within soil types, by reference …

From Theory To Practice: What Should We Have In Mind When Building Effective And Sustainable Payments For Ecosystem Services (Pes) Schemes For Silvo-Pastoral Systems? Evidence From Colombia, M. Díaz, K. Enciso, N. Triana, S. Burkart

IGC Proceedings (1997-2023)

In most Latin American countries, payment for ecosystem services (PES) can be a useful strategy for restoration and conservation of the environment, increasing productivity and promoting sustainable development in rural areas. Despite these plausible benefits, PES implementation can be challenging due to the contextual framework in which it takes place (e.g. institutional weakness in the implementation and monitoring stages, limited connectivity among stakeholders, low adoption levels of agricultural technology). This study aims at evaluating PES schemes for silvo-pastoral systems in Colombia by considering six dimensions based on an extensive literature review: policy and governance; social context; environmental context; risks and …

Sustainable Intensification Of Livestock Systems Using Forage Legumes, José C. B. Dubeux Jr., Lynn E. Sollenberger

IGC Proceedings (1997-2023)

Global human population is increasing and expected to reach 9.7 billion people by 2050. Sustainable intensification (SI) of agricultural systems is key to increase food production while minimizing impact on global natural resources. Forage legumes provide a myriad of ecosystem services (ES) and represent an important tool for promoting SI in livestock systems. Forage legumes associate with soil microorganisms to reduce atmospheric N₂. This N input represents a valuable contribution to increase net primary productivity with reduced C footprint. In addition, forage nutritive value generally increases, resulting in greater animal performance. When forage legumes are integrated into livestock …

Real-World Applications For Virtual Fences – What Are Potential Benefits For Conservation?, F. Riesch, M. Komainda, J. Horn, J. Isselstein

IGC Proceedings (1997-2023)

Livestock grazing can enhance biodiversity and ecosystem services in agricultural landscapes. In many parts of Europe, however, grazing has lost its importance, especially in the dairy sector. Large proportions of permanent grassland have been converted to arable land or intensified by fertilization and frequent defoliation. The disappearance of large herbivores and extensively grazed pastures contributes to the loss of structural, functional and biological diversity and ecosystem services. Modern technologies, which circumvent the cost- and labour-intensive installation of physical fences, could facilitate a precise spatio-temporal management of livestock and promote grazing. We reviewed the literature on the state-of-the-art of virtual fencing, …

Herbage And Livestock Responses For N-Fertilized And Grass-Legume Grazing Systems, D. M. Jaramillo, José C. B. Dubeux Jr., L. M. D. Queiroz, L. Garcia, E. R. S. Santos

IGC Proceedings (1997-2023)

Forage legumes provide an alternative N source in grazing systems. The objective was to evaluate plant and animal responses in N-fertilized or grass-legume-based systems under continuous stocking during winter and summer, from 2016-2019. The three treatments consisted of year-round forage systems including winter and summer forage components. The first system (Grass+N) included N-fertilized (112 kg N ha^-1 yr^-1) ‘Argentine’ bahiagrass (Paspalum notatum) pastures during the summer, overseeded with a mixture (56 kg ha^-1 of each) of ‘FL 401’ cereal rye (Secale cereale) and ‘RAM’ oat (Avena sativa) during winter with …
