Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2021, Leah English, Jennie Popp May 2023

Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2021, Leah English, Jennie Popp

Research Reports and Research Bulletins

Agriculture and associated agricultural activities are major contributors to the Arkansas economy. Agriculture is defined as the sum of agricultural production and processing activities, unless otherwise specified, and includes crop and animal production and processing, agricultural support industries, forestry and forest products, and textile goods. Agriculture contributes to the economy through direct agricultural production and processing, leading to economic activity in other parts of the economy.

This report is the sixteenth in a series that examines agriculture’s economic contribution to the Arkansas economy. The total economic contribution of agriculture (direct, indirect, and induced effects) on value added, employment, and labor …

These guides address a recognised gap in readily applicable and easily accessible information on southern rangelands pasture condition and management.

These guides provide descriptions and images for southern rangelands pastures with similar management requirements for the grazing of native pastures by livestock. Therefore, the focus is on palatability of vegetation to livestock, and the effects of livestock management and external factors on the condition of the vegetation and soils.

The first section provides an overview and map, introduces concepts and terms important to understanding arid shrubland management in general, these guides in particular; and includes an economic analysis of the …


Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr Mar 2021

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr

Bulletins 4000 -

The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.

Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Recreational fisheries (RF) are complex social-ecological systems that play an important role in aquatic environments while generating significant social and economic benefits around the world. The nature of RF is diverse and rapidly evolving, including the participants, their priorities and behaviors, and the related ecological impacts and social and economic benefits. RF can lead to negative ecological impacts, particularly through overexploitation of fish populations and spread of non-native species and genotypes through stocking. Hence, careful management and monitoring of RF is essential to sustain these ecologically and socioeconomically important resources. This special issue on recreational fisheries contains diverse research, syntheses, …


Heterogeneity Of Avian Breeding Habitat On Grazing Lands Of The Northern Great Plains, Maggi S. Sliwinski May 2017

Heterogeneity Of Avian Breeding Habitat On Grazing Lands Of The Northern Great Plains, Maggi S. Sliwinski

School of Natural Resources: Dissertations, Theses, and Student Research

Native rangelands in the Great Plains are largely privately owned and used for beef production. Vegetation heterogeneity is important for maintaining biodiversity, but private land may be more homogenous than desired. My research had two components: 1) to examine whether a variety of grazing strategies created vegetation heterogeneity in a large, intact rangeland, and 2) to understand beef producers’ attitudes about vegetation heterogeneity.

First, I sampled vegetation structure, composition, and bird abundance at multiple plots on eleven management units in Cherry County, Nebraska. Units were managed with commonly used grazing strategies (e.g., short-duration grazing and season-long continuous grazing). I examined …


Protected Areas As Social-Ecological Systems: Perspectives From Resilience And Social-Ecological Systems Theory, Graeme S. Cumming, Craig R. Allen Jan 2017

Protected Areas As Social-Ecological Systems: Perspectives From Resilience And Social-Ecological Systems Theory, Graeme S. Cumming, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Conservation biology and applied ecology increasingly recognize that natural resource management is both an outcome and a driver of social, economic, and ecological dynamics. Protected areas offer a fundamental approach to conserving ecosystems, but they are also social-ecological systems whose ecological management and sustainability are heavily influenced by people. This editorial, and the papers in the invited feature that it introduces, discuss three emerging themes in social-ecological systems approaches to understanding protected areas: (1) the resilience and sustainability of protected areas, including analyses of their internal dynamics, their effectiveness, and the resilience of the landscapes within which they occur; (2) …

Harvest Strategy Policy And Operational Guidelines For The Aquatic Resources Of Western Australia, Western Australia. Dept. Of Fisheries Jun 2015

Harvest Strategy Policy And Operational Guidelines For The Aquatic Resources Of Western Australia, Western Australia. Dept. Of Fisheries

Fisheries management papers

Harvest strategies establish the decision rules that determine the appropriate harvest levels for all sectors to meet the ecological, economic and social objectives established for a resource. The development and implementation of formal harvest strategies is considered sound practice in contemporary fisheries management. A number of recent legislative (new Aquatic Resources Management Act, ARMA) and policy (Marine Stewardship Council, MSC) initiatives require the development of formal harvest strategies for the key aquatic resources in Western Australia (WA).

The Management Of Feral Pig Socio-Ecological Systems In Far North Queensland, Australia, Gabriela Shuster Jan 2012

The Management Of Feral Pig Socio-Ecological Systems In Far North Queensland, Australia, Gabriela Shuster

Antioch University Dissertations & Theses

The development of management programs for socio-ecological systems that include multiple stakeholders is a complex process and requires careful evaluation and planning. This is particularly a challenge in the presence of intractable conflict. The feral pig (Sus scrofa) in Australia is part of one such socio-ecological system. There is a large and heterogeneous group of stakeholders interested in pig management. Pigs have diverse effects on wildlife and plant ecology, economic, health, and social sectors. This study used the feral pig management system as a vehicle to examine intractable conflict in socio-ecological systems. The purpose of the study was …


Changing Climate, Changing Business Practices : Lessons From Innovative Growers, David Gray, Nicole Baxter, Meredith Fairbanks, Geraldine Pasqual Sep 2011

Changing Climate, Changing Business Practices : Lessons From Innovative Growers, David Gray, Nicole Baxter, Meredith Fairbanks, Geraldine Pasqual

Bulletins 4000 -

Climate change and increasing seasonal variability are challenging the production efforts of growers in lower rainfall environments of the Western Australian grain belt. Significantly less rainfall than the long-term average has fallen across southwest Western Australia during the past 30 years.

Seasonal rainfall has also become more variable with later starts to the growing season and a general shift to more summer and less winter rainfall. Day and night-time temperatures, particularly in winter and autumn, have gradually increased, while in some areas, the risk of frost in spring has increased.


Greener Pastures 1 - The Greener Pasture Project: Managing Nutrients In Dairy Pastures, John Lucey, Mike Bolland, Don Bennett, Richard Morris, Bill Russell, Martin Staines Feb 2011

Greener Pastures 1 - The Greener Pasture Project: Managing Nutrients In Dairy Pastures, John Lucey, Mike Bolland, Don Bennett, Richard Morris, Bill Russell, Martin Staines

Bulletins 4000 -

As dairy farmers have strived to maintain profitability, many have farmed more intensively. More cows are milked and increasing inputs of fertiliser and purchased feed are used per hectare. However, these increased nutrient inputs have far exceeded the increase in nutrient output in milk production. The increasing nutrient surplus (inputs minus outputs) from intensification on dairy farms has met with increasing community concern about the environmental footprint of the dairy industry. In some other countries, dairy farmers who have intensified by increasing nitrogen inputs are now faced with legislation controlling the amount of fertiliser nitrogen that they can use.

The …

Report On Phosphorus And Potassium Experiments Conducted On Partner Farms Of The Greener Pastures Project, Mike Bolland, Ian Guthridge, Graham Blincow, Peter Needs

Bulletins 4000 -

Dairy production in south-western Australia occurs predominantly on sandy soils in the greater than 800 mm annual average rainfall areas of the region. The climate is Mediterranean-type, typically with cool, wet May-October growing seasons and hot, dry November-April. Most dairy pastures are rain-fed and comprise the annual species Subterranean Clover (clover, Trifolium subterraneum L.), Annual Ryegrass (Lolium rigidum Gaud.) and Italian Ryegrass (L. multiflorum Lam.).

Paddock grown pasture is the cheapest source of feed for dairy production in the region (Dilley and Howes 1998). To remain profitable in the face of diminishing returns, dairy farmers have modified their grazing management …


Herbicides And Amphibian Populations, Zach Shirk Apr 2010

Herbicides And Amphibian Populations, Zach Shirk

Department of Environmental Studies: Undergraduate Student Theses

Amphibians are a unique class of species that are found worldwide except Antarctica and Greenland. They range in size from a few millimeters to over six feet long. Amphibian’s habitats are as various as their size, but one thing in common is that amphibians require an aquatic location to breed. Amphibians live in deserts, mountain prairies, rain forest, wetlands, and almost everywhere in between. Amphibians are an integrated part of most natural ecosystems across the world. Amphibians are a critical part of many food chains; they provide the important link between secondary and tertiary consumers. Amphibians are indicator species in …


Potassium For High Rainfall Pastures, Mike Bolland, Bill Russell Jan 2010

Potassium For High Rainfall Pastures, Mike Bolland, Bill Russell

Bulletins 4000 -

Potassium plays a major role in plant growth. It maintains the solutions in plant cells at ionic strengths suitable for maintaining strong plant walls and for the proper functioning of leaf pores (stomata) and plant processes such as photosynthesis, transport of sugars and enzyme activation.

Potassium does not become a direct part of the plant structure but acts to regulate water balances, nutrient and sugar movement in plant tissue. Plants deficient in potassium cannot use other nutrients and water efficiently. They are less tolerant of stresses such as drought and waterlogging and are more susceptible to pests and diseases.

Lime For High Rainfall Pastures: Above 800mm Average Annual Rainfall, Mike Bolland, Bill Russell Sep 2008

Lime For High Rainfall Pastures: Above 800mm Average Annual Rainfall, Mike Bolland, Bill Russell

Bulletins 4000 -

Conventional agriculture acidifies soil. As your soil becomes more acid, productive pasture species disappear and are replaced by species of low agricultural value. It is a waste of money to apply expensive fertiliser to pastures which are inherently poorly productive because they are growing in an acid soil.

The paper examines the types of lime available, how to select lime for quality and when and how much lime to apply. Maganese toxity and aluminum toxicity are examine, how to test your soil, and affect of soil acidity on bacteria and other microorgansims.

Most pastoralists appreciate the need to deliver an economic, environmental and social 'profit' from their business. Achieving these profits can be a real challenge given the comparatively low productive potential and the substantial seasonal variation in the WA Southern Rangelands region. This guide was written to assist pastoralists to meet their specific livestock production, financial and range condition objectives through the better alignment of feed demand (stocking rate) to feed supply (carrying capacity). We provide nine basic steps that simplify the process of managing the feed supply, equipping pastoralists with the tools to make· decisions and to critically assess the …
