Rate Of Decomposition And Release Of Nutrients From Litter In A Heteropogon Contortus-Bothriochloa Bladhii Dominant Native Pasture, Deryk G. Cooksley, J H. Prinsen, C J. Paton, A T. Lisle

IGC Proceedings (1977-2023)

Litter dry matter (DM) decomposition and nutrient (N, P, K and S) release were measured for 8, 6-monthly periods in south-eastern Queensland. Litter collected from native paslure growing on a range of soil types was hammer milled, and buried in nylon bags at the collection site, Moisture and (tn a lesser extent) temperature had a greater effect on DM disappearance from nalive pasture litter than its chemical composition or the soil type. A simple index of litter disappearance was derived from average air temperature and surface (0-10 cm) soil water. Based on long-term rainfall and temperature data, 24.8% of litter …

Nitrogen Use Efficiency By Chloris Gayana During The Cold Season On The Island Of La Reunion, Gilles Mandret, A Ourry, P F. Chaballier, J Salette

IGC Proceedings (1977-2023)

Cattle breeding improvement at the island of la Reunion (Indian Ocean) had to face 2 major problems: increase the production of heifers and improve forage production. Deficit of forage production will require intensification of farming practices and more particularly higher nitrogen inputs in grassland. Moreover, the great pedoclimatic diversity associated with altitude variability implies use of both temperate and tropical species with or without irrigation. Since 1990 experiments have been undertaken with 1SNH4 15NO3 -fertilised Chloris, gayana, Pennisteum clandestinum, and Lolium hybridum during wet and dry seasons. The C, gayana stand was irrigated when necessary and porous ceramic cups …

Soil Factors And Grassland Type Relationships In The Subhumid Zone Of Northern Benin, Brice Sinsin

IGC Proceedings (1977-2023)

Soil samples collected under different grassland vegetations were studied. Mineral components were closely related to organic matter (OM) level, which was significantly correlated with cation exchange capacity (CBC). OM had an estimated average CEC of 1.8 me./100 g soil. Total exchangeable bases depended on both organic and mineral components and pH. Exchangeable K and Na depended mostly on clay and silt fractions, Cluster and principal component analysis enabled recognition of 5 clusters each grouping different grassland vegetation types. This confirms that soil factor analysis supports the field descriptions of the study soils but is inadequate to discriminate floristic composition at …

Efficient Nitrogen Fertilizer Strategies For Tropical Beef And Dairy Production Using Summer Rainfall And Soil Analysis, M A. Gilbert, N M. Clarkson

IGC Proceedings (1977-2023)

Nitrogen (N) deficiency is a major limitation to growth of pastures in tropical and subtropical regions. In the tropics and subtropics of north-eastern Australia, grass yield is curvilinearly related (R2=0.75) to summer rainfall and the rate of N fertiliser. Data from a range of grazing experiments also indicate that beef and dairy production (kg/ ha) are related to N fertiliser rate in a curvilinear manner; production is near optimum at N rates of 250-300 kg N/ha/year, when summer rainfall is >1000 mm. Given the importance of summer rainfall and N fertiliser, climatic analysis can enhance the usefulness of N fertiliser …

Effects Of Tillage On Soil Nitrogen And Growth Of Three Rhodes Grass (Chloris Gayana Kunth) Cultivars On A Typical Haplustol, M F. Barbero, C B. Loza, P C. Faustinelli

IGC Proceedings (1977-2023)

In the northern part of the province of Cordoba (32°S), Argentina pasture production is limited by nitrogen availability. The work, using Rhodes ( Chloris gaya11a Ku nth) of 3 origins, evaluated the effect of various dates of surface tillage on the dry matter production and nitrogen content of 3 Rhodes grass cultivars: a local ecotype (Cordobes), cv. Samford and cv. Katambora. Dry matter and nitrogen production was increased in the 3 cultivars when the tillage was done before the rainy season.

Soil Quality And Its Management In Humid Subtropical And Tropical Environments, R Lal, F P. Miller

IGC Proceedings (1977-2023)

The subtropical and tropical ecoregions of the world cover an extensive area of about 4900 million ha, and are characterised by deeply weathered soils derived from geologically old materials, In humid regions, the combination of high temperature and moisture has enhanced the rate and depth of weathering, accelerated leaching and led to the formation of acidic soils with low activity clays. The seasonally dry tropics extend over about 2475 million ha, characterised by savanna vegetation including a mixture of trees and grasses, In comparison with humid ecoregions, the grazing potential is high for soils and climate of the seasonally dry …

Origin And Regulation Of Nutrient Supply To Plants In Humid Tropical Grasslands, Patrick Lavelle, Michael J. Swift

IGC Proceedings (1977-2023)

Stocks and fluxes of carbon and nutrients ln tropical grasslands are determined by a suite of hierarchically organised factors.· Rain foll patterns and edaphic factors first determine the nature of the vegetation, the quantity and quality of organic inputs, and the relative allocation to the production of shoots or roots. Grazing by cattle or native herbivores, and fires, are other processes that significantly affect nutcient cycling. The nature and intensity of constraints exerted by these factors separate different types of tropical grasslands, i.e., savannas induced by the seasonality and limited abundance of rainfall, savannas induced by the poverty of soils …

Viability Of Grass-White Clover Swards For Dairying Production In The Uk, J A. Bax, G.E J. Fisher

IGC Proceedings (1977-2023)

The potential of extensification to reduce production within the BC has increased interest in the use of white clover (Trifolium repens) for milk production. In a long-term system study to determine the potential of white clover, 2 herds of 70 cows were managed on either grass swards plus 350 kg N/ha/annum or on grass-white clover swards which received no inorganic N. Continuous grazing and up to 3 conservation cuts a year had no adverse effects upon clover contents in the mixed swards. Total silage OM yields/ha from the grass-white clover swards were 0,82, 0.81 and 0.96 of those …

Creating A Caring Culture, Julie Harrison-Swartz

Wisdom & Compassion: The LUSON Journal

Caring is a word that is synonymous with nursing. Nurses are equipped to engage in all aspects of patient care and be present. Caring and presence are also imperative in nursing education. While caring is instrumental to patient healing and outcomes, it is equally important in demonstrating care through nursing education. While convenient it is often difficult to express caring in the remote environment. This paper will describe a brief history of nursing, concept of caring, and nursing education.

Trauma-Informed Care And Support For Dei: Exemplars In Diabetes And Self-Reflection, Karla Giese

Wisdom & Compassion: The LUSON Journal

Traumatic life experiences may disproportionately affect individuals with social disparities, marginalization, or injustices.

Inclusion Of American Sign Language In Science And Engineering, Alejandro Mejia-Tejada

Society for American Sign Language Journal

For the general public, deaf people are typically known for their signing skills and living as signers, not speakers. However, there is more to this picture. Specifically, one area of consideration and investigation relates to how American Sign Language (ASL) is used as a language in the domains of science and engineering. The other area of investigation relates to how deaf people contribute to the STEM (science, technology, engineering, and math) fields. It will be demonstrated that deaf community members are making inroads into STEM through working as scientists and engineers, including one deaf person known for participating in training …

Hereditary Deafness And Society: The Quest For Ethical Awareness, Danielle Lavigne

Society for American Sign Language Journal

An excellent study of genetics and deafness is Martha’s Vineyard, a small island off the Massachusetts coast that was once known to have a sizable deaf population. This community that prevailed during the eighteenth and nineteenth centuries relates many genetic concepts, giving insight as to why the deaf population was larger in proportion than that on the mainland. The paper will cover hereditary deafness in more depth than what has been discussed in the American Sign Language/Deaf Studies literature. This includes understanding the significance of population genetics. The paper also takes into consideration that many hearing residents of Martha’s Vineyard …

We review the functioning and sustainability of coastal marshes and mangroves. Urbanized humans have a 7,000-year-old enduring relationship to coastal wetlands. Wetlands include marshes, salt flats, and saline and freshwater forests. Coastal wetlands occur in all climate zones but are most abundant in deltas. Mangroves are tropical, whereas marshes occur from tropical to boreal areas. Quantification of coastal wetland areas has advanced in recent years but is still insufficiently accurate. Climate change and sea-level rise are predicted to lead to significant wetland losses and other impacts on coastal wetlands and the humans associated with them. Landward migration and coastal retreat …

Walden Dissertations and Doctoral Studies

Autism spectrum disorder (ASD), characterized by challenges in social communication and repetitive behaviors, is a developmental disability that impacts over five million adults in the United States. Despite the significant amount of research literature on the association between health and employment in the general population, there remains a gap in research on the relationship between health and employment in adults with autism. Utilizing the Social Ecological Model (SEM) framework, this study examined whether there is a relationship between employment, current living status, non-paid activities, United States Census regions, type of health insurance, and health status when controlling for age, race, …

Determination Of A New Spring-Flying Species Of The Pterourus Glaucus Complex (Papilionidae) In Southern New England, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

The Pterourus glaucus complex in three southern New England states is analyzed for cryptic speciation. What was historically considered to be one species, P. glaucus (Linnaeus, 1758), was recently split to separate P. canadensis (Rothschild & Jordan, 1906) at species rank (Hagen et al., 1991). Additionally, P. appalachiensis Pavulaan & Wright, 2002, was described as an Appalachian Mountain endemic. The western member of the complex, P. rutulus (Lucas, 1852), has frequently been considered a subspecies of P. glaucus (Scott, 1986; Tyler, Brown & Wilson, 1994), as was P. alexiares (Höpffer, 1866) (Tyler, Brown & …

Biological clocks and other molecular biomarkers of aging are difficult to implement widely in a clinical setting. In this study, we used routinely collected hematological markers to develop an aging clock to predict blood age and determine whether the difference between predicted age and chronologic age (aging gap) is associated with advanced aging in mice. Data from 2,562 mice of both sexes and three strains were drawn from two longitudinal studies of aging. Eight hematological variables and two metabolic indices were collected longitudinally (12,010 observations). Blood age was predicted using a deep neural network. Blood age was significantly correlated with …
