Eragrostis Curvula Effects On Above And Below-Ground Plant Species Richness And Diversity, Jed Brown, A. Merchant, L. Ingram
Eragrostis Curvula Effects On Above And Below-Ground Plant Species Richness And Diversity, Jed Brown, A. Merchant, L. Ingram
IGC Proceedings (1977-2023)
Monitoring and managing the soil seed bank is fundamental to land management as it constitutes the future generations of invasive plant communities. Invasive plants have traits that result in high recruitment through increased seed generation, short seed dormancy and phenotypic plasticity. Furthermore, invasive plants with growth forms that inhibit the growth and recruitment of other species can lead to monocultures and associated reduction in above-ground biodiversity, potentially negatively impacting the soil seed bank diversity and ecosystem functions and services. Eragrostis curvula is one such species that has many of these invasive traits, including high propagule generation, and can exclude plant …
The Importance Of Forage Legume Epigenetics In The Anthropocene, J. Brady, J. P. Muir, A. Falk
The Importance Of Forage Legume Epigenetics In The Anthropocene, J. Brady, J. P. Muir, A. Falk
IGC Proceedings (1977-2023)
As climates change and economic as well as ecological pressures to produce more ruminant product on less land in the Anthropocene increase, the importance of using cutting-edge methods for forage legume improvement grows. The immediate return rate and turnaround on investment is likely greater for multi-species incorporation into grasslands but focusing on intraspecific variability and diversity could also contribute. The role of forage legumes in cultivated pasture and rangeland biodiversity as well as stability depends on genetics as well as management. Their epigenetics, however, may become increasingly important as climatic extremes and ecological pressures grow due to human-induced factors. Unfortunately, …

Assessing The Usefulness Of Senna Obtusifolia, An Invasive Plant Species In West Africa Rangelands, A. Zaré, O. Ouédraogo, A. Linstädter
IGC Proceedings (1977-2023)
Senna obtusifolia is a less appreciated plant species. Its invasion has led to the disappearance of several herbaceous species of interest in West Africa rangelands. As adaptation strategy, people use it to substitute for those that have disappeared. This study aimed to assess the importance of this species for animal and local ethnic groups according to two contrast climate zones in Burkina Faso. Ethnobotanic survey mixed with direct observations on the field were conducted. Three hundred (300) people from height (8) ethnic groups were interviewed. The survey technique was semi-structured interviews using a previously tested semi-structured questionnaire. At the early …
Responses Of Plant Functional Diversity To Long-Term Warming And Nitrogen Addition In A Desert Steppe, Y. Zhu, L. Tian, H. Y. Ren, G. D. Han
Responses Of Plant Functional Diversity To Long-Term Warming And Nitrogen Addition In A Desert Steppe, Y. Zhu, L. Tian, H. Y. Ren, G. D. Han
IGC Proceedings (1977-2023)
Plant functional traits are closely related to ecosystem functions, and can indicate changes in ecosystem functions. Plant functional diversity is an important component of biodiversity, which can more accurately predict the changes of ecosystem functions or processes than species diversity, and is the main determinant of ecosystem functions or processes. In order to study the impact of global climate change factors (i.e., warming and nitrogen deposition) on the plant functional diversity in a desert steppe, we conducted a long-term warming and nitrogen addition experiment in northern China for 15 years (2006 - 2020). In 2020, we measured the plant height, …

Evaluating Herbicides For The Control Of Multiflora Rose And Autumn Olive In Eastern Ohio, C. Zoller, D. Kreager, T. G. Wiseman, C. Martin, A. Essman, C. Gelley, C. Little, M. Loux
IGC Proceedings (1977-2023)
Invasive plants cause billions of dollars annually in damage, displace desirable plants, and reduce available land area for livestock grazing. Multiflora rose and autumn olive are two such species prevalent across the Eastern United States. Originally introduced for livestock containment and erosion control, these plants have become widespread, resulting in reduced animal grazing. The Eastern Agricultural Research Station (EARS) is located in Southeast Ohio and is owned by The Ohio State University. Much of the more than 2,000 acres has a history of surface mining and was reclaimed with the planting of multiflora rose and autumn olive. These plants have …

Biodiversity—The Birds And The Bees And Healthy Grasslands, D. Borrenpohl, Pat D. Keyser
IGC Proceedings (1977-2023)
Losses in biodiversity abound in modern agroecosystems, and biodiversity loss hampers ecosystem function and primary productivity comparable to abiotic stress. One of the most endangered ecosystems in the world is North American tallgrass prairie, and native birds and pollinators that historically depended on tallgrass prairie are in precipitous decline. Fortunately, native warm-season grasses that dominated tallgrass prairie present a valuable opportunity for summer forage to beef producers in the Eastern United States—a time when coolseason grasses endure a lack in productivity called the “summer slump.” Tallgrass prairie was sustained by periodic disturbance from grazing and fire, and combining fire and …
The Soil Health Properties Of Native Grasslands, C. Bitler, Pat Keyser
The Soil Health Properties Of Native Grasslands, C. Bitler, Pat Keyser
IGC Proceedings (1977-2023)
Due to an increased interest in soil health and the role soils can have in carbon sequestration, native grasslands are getting heightened attention. Native grasslands are known for their deep top-soils that develop over time through the accumulation of soil organic matter. The deep and fibrous root systems that make up two-thirds of the biomass of native grasslands are the primary contributors to the soil organic carbon (SOC) content of grassland soils. Increased SOC content has a cascading effect on soil health metrics through increasing water infiltration and water holding capacity, supporting diverse and abundant soil microbial life, and improving …
Using Functional Ecology To Predict Restoration Success In Managed Grasslands, J. Bergman
Using Functional Ecology To Predict Restoration Success In Managed Grasslands, J. Bergman
IGC Proceedings (1977-2023)
Plants have developed remarkable functional variation over evolutionary time to cope with different environmental conditions. As a result, functional variation – measurable as functional traits above and below ground – can be found within but also among grassland communities today. The functional space covered by a community is thereby restricted by environmental factors while each single species within the community inhabits a specific niche with a certain breadth along different environmental gradients. Data from field sampling in European grasslands have shown, that species intraspecific functional variation can cover considerable amounts of possible functional spaces, hence holding the potential to establish …
Toxic Plants In Grasslands And Their Impact On Livestock, A. C. Barr
Toxic Plants In Grasslands And Their Impact On Livestock, A. C. Barr
IGC Proceedings (1977-2023)
Grasslands are critical infrastructure for most cow/calf operations. Quality and abundance of pasture grasses directly influence livestock rate of gain, thereby affecting livestock margins and production costs, which determine the profitability of stocker operations. Successful cattlemen control weeds to preserve healthy pasture but also to prevent plant poisonings that may reduce individual animal performance or cause fatalities. Integrated Toxic Plant Management (ITPM) programs teach ranchers to identify the potentially toxic plants, recognize symptoms of plant poisonings, and use appropriate strategies to control those plants. Toxic plants can produce a range of effects in cattle and other grazing species. Nightshades ( …
Response Of Reproductive Phenology To Soil Water Content Of Stipa Breviflora Under Warming And Nitrogen Application, L. Bai, H. Y. Ren, G. D. Han
Response Of Reproductive Phenology To Soil Water Content Of Stipa Breviflora Under Warming And Nitrogen Application, L. Bai, H. Y. Ren, G. D. Han
IGC Proceedings (1977-2023)
Plant phenology is considered as the most direct and sensitive characteristic indicators of plant response to regional climate change. Based on the observation data of phenology and soil water content of Stipa breviflora in an experimental platform of warming and nitrogen application in Inner Mongolia desert steppe from 2009 to 2019. The results showed that warming and nitrogen application significantly advanced the reproductive phenological period (P < 0.001), and the interaction of warming and nitrogen application promoted the advance of reproductive phenological period (P < 0.05).

Modelling Basal Area Of Perennial Grasses In Australian Semi-Arid Wooded Grasslands, S. G. Marsden, K. C. Hodgkinson
IGC Proceedings (1977-2023)
In many semi-arid pastoral systems, landscape processes easily become dysfunctional. Shifts to less functional states may be irreversible, and have long-term consequences for pastoral profitability and social viability of rural communities. Typically, shifts to lower functional states involve a decline in perennial grasses (Hodgkinson, 1994). Here we develop a conceptual basis for modelling the basal area of perennial grasses in a semi-arid grassland and validate the model using data from a 10-year grazing study.
The Effect Of Manipulated Conservation Margins In Intensively Grazed Dairy Paddocks On The Biodiversity Of Pteromalidae And Braconidae (Hymenoptera: Parasitica), A. Anderson, G. Purvis, A. Helden, H. Sheridan
The Effect Of Manipulated Conservation Margins In Intensively Grazed Dairy Paddocks On The Biodiversity Of Pteromalidae And Braconidae (Hymenoptera: Parasitica), A. Anderson, G. Purvis, A. Helden, H. Sheridan
IGC Proceedings (1977-2023)
Conserving field margins provides an opportunity to enhance biodiversity in agricultural landscapes. The parasitoid Hymenoptera represent one of the most diverse and biologically specialised of all insect groups and play an important role in insect pest control (LaSalle & Gauld, 1993). The diversity of parasitiods in any habitat is theoretically likely to reflect the diversity of host taxa. The aim of this study was to assess the effects of field margin manipulations on the diversity of parasitoids as a wider indication of effects on general arthropod diversity.

IGC Proceedings (1977-2023)
Agricultural soils have the potential not only to be sinks of carbon dioxide (CO2) but also to mitigate the emissions of this gas to the atmosphere, thus, alleviating global warming. Perennial tropical grasses and rice upland and lowland varieties exhibit a large untapped genetic diversity in their root systems (e.g., deep rooting ability, exudation rates and chemical composition) that, if unlocked, could contribute to increased food production in crop-livestock systems while enhancing soil organic carbon (SOC) in tropical regions. Naturebased solutions that improve crop adaptation and SOC storage in tropical soils could help to remove CO2 from …

IGC Proceedings (1977-2023)
Salinity stress is one of the most damaging stresses in crop plants. It reduces the productivity of the soil and makes it unsuitable for crop cultivation. Fodder crops are considered the best alternative in such uncultivable land. Using salinity-affected land for pasture development is the best alternative to utilize such lands. However, the extent of salinity tolerance varies among different grass species. In this study, Pearl millet Napier hybrids (PMN hybrid) and guinea grass varieties were studied for salinity tolerance in artificially created saline soils in the ratio of 13:7:1:2 (NaCl: Na2SO4: MgCl: CaSO4, …

Climate change has decreased rainfall in Southern Chile affecting the productivity of the grasslands that sustain the dairy and beef cattle industries. These grasslands are mainly mixtures of Lolium perenne L. and Trifolium repens L. Thus, we study the response on the establishment of a mixture of these two species to three levels of soil water content and two levels of nitrogen (N) fertilization. The trial was carried out in containers sowed in a complete randomized block´s design. Soil moisture measurements were taken daily. N fertilizations was applied at the establishment and every 60 days. Leaf appearance rate was measured …

High-yielding mechanized rice production requires large amounts of nitrogen (N) fertilizer, which can be particularly costly to producers when applied in excess. The development of a tissue test to detect overapplication of N to rice is needed. Nitrogen response trials arranged in a randomized complete block design were established to identify a critical concentration threshold for a tissue test to detect excess N availability. Rice stalk samples were collected from 0 to 20 cm above the soil within 5 days of harvest and analyzed for NO3 −-N concentration. Two models were fit to the data to represent rice grain …
Assessing The Performance Of Agricultural Systems In The Inland And Coastal Regions Of Northern Portugal Using Indicators: Establishing The Foundation Towards Better Agricultural Practices, Genevieve Gehlken
Independent Study Project (ISP) Collection
This study conducts a comprehensive evaluation of agricultural systems in the distinct coastal and inland regions of Northern Portugal. Employing key indicators, including soil erosion, nitrogen surplus, irrigation practices, Agricultural Gross Domestic Product (GDP), and crop yield, the analysis reveals statistically significant disparities and unique challenges in each region. The coastal areas, marked by higher agricultural GDP, exhibit distinct economic dependencies on agriculture, while the inland regions face challenges related to water scarcity, soil erosion, and rural isolation. The looming threat of climate change adds complexity to these dynamics, further highlighting the need for region-specific, sustainable agricultural practices. In the …

Crop, Soil and Environmental Sciences Faculty Publications and Presentations
Management and design affect systems’ ability to deliver ecosystem services and meet sustainable intensification needs for a growing population. Soil–plant–animal health evaluations at the systems level for conventional and silvopastoral environments are lacking and challenge adoption across temperate regions. Impacts of silvopasture on soil quality, microclimate, cattle heat stress, forage quality and yield, and cattle weight gain were compared to a conventional pasture in the mid-southern US. Here, we illustrate silvopastures have greater soil organic carbon, water content, and overall quality, with lower temperatures (soil and cattle) than conventional pastures. Forage production and cattle weight gains were similar across systems; …

A New System For Plant Experiments On Biodiversity Or Multi-Species Competition, John Connolly, L. Kirwan
A New System For Plant Experiments On Biodiversity Or Multi-Species Competition, John Connolly, L. Kirwan
IGC Proceedings (1977-2023)
Considerable discussion in recent years has focused on the design of competition and biodiversity experiments (Connolly et al., 2001a; Allison, 1999). Few agronomic experiments with >2 plant species have been conducted in greenhouse conditions (Gibson et al, 1999) or in the field (Connolly et al., 2001b). In many experiments the effects of density and initial species size have been confounded. The effects of species richness and evenness also are confounded frequently. The proposed system provides a framework of design and analysis, in which to address questions of function at community level and of structure and competition at …

Native Grasses Seeded Into A Cool-Season Pasture Encouraged By Low Resource Availability, J. E. Doll, R. L. Cates, R. D. Jackson
IGC Proceedings (1977-2023)
Native prairie of the Upper Midwest, which was dominated by warm-season (C4) grasses, now exists as relatively small relict and restored patches (Curtis 1959). Re-introduction of natives into grazed agroecosystems would promote genetic, species, and landscape diversity. Extensive re-introduction of C4 grasses will require a shift away from the paradigm of maximizing production because C4 grasses have higher C:N ratios than C3 grasses rendering them inferior forage species. Nonetheless, there is great interest amongst the grazing community of the Upper Midwest in establishing native grasses as a means of improving wildlife habitat and increasing belowground …

In compliance with European commitments to the Convention on Biological Diversity, the conservation and enhancement of biodiversity within agricultural land is a primary objective of current agri-environmental measures. However, there is a widespread lack of information concerning the effectiveness of agri-environmental schemes in Europe, (Kleijn & Sutherland, 2003). In large part, this is due to uncertainties about selection of appropriate biological indicators of biodiversity (Buchs, 2003; Duelli & Obrist, 2003).
