Impact Of The Agricultural Sector On The Arkansas Economy In 2001, Jennie Popp, Gina Vickery, H. L. Goodwin Jr., Wayne Miller
Impact Of The Agricultural Sector On The Arkansas Economy In 2001, Jennie Popp, Gina Vickery, H. L. Goodwin Jr., Wayne Miller
Research Reports and Research Bulletins
Agriculture has historically been one of Arkansas’ primary economic sectors. Agriculture is defined as the sum of agricultural production and processing activities unless otherwise specified. Agriculture contributes to the economy through direct agricultural production and value-added processing which generates economic activity in other parts of the economy.
Effects Of Herbicide Application Of Foliar Morphology And Nutrient Concentrations In Mid-Rotation Pine Plantations, Prabudhda Dahal, Hal O. Liechty
Effects Of Herbicide Application Of Foliar Morphology And Nutrient Concentrations In Mid-Rotation Pine Plantations, Prabudhda Dahal, Hal O. Liechty
Journal of the Arkansas Academy of Science
Application of herbicide to reduce competing brush and hardwood species is a common silvicultural activity in young loblolly pine (Pinus taeda) stands. A reduction in competition generally increases the amount of available resources to the loblolly pine crop trees thereby increasing foliage biomass, fascicle dimensions, and foliar nutrient concentrations. To what extent herbicide application and competition control alters these foliar characteristics in mid-rotation stands has rarely been reported. The purpose of this paper is to evaluate whether the application of herbicide alters the morphology, mass, and/or nitrogen concentration of mid-rotation loblolly pine foliage. We aerially applied an imazapyr herbicide to …
Crown Radius And Diameter At Breast Height Relationships For Six Bottomland Hardwood Species, Brian Roy Lockhart, Robert C. Weih Jr., Keith M. Smith
Crown Radius And Diameter At Breast Height Relationships For Six Bottomland Hardwood Species, Brian Roy Lockhart, Robert C. Weih Jr., Keith M. Smith
Journal of the Arkansas Academy of Science
The relationship between a tree's crown radius and diameter at breast height (DBH) has a variety of uses including forest competition studies, tree crown densities, spacing and stocking relationships, wildlife habitat suitability models, and tree volume estimations. Estimating DBH from mean crown radius (MCR) is of interest to natural resource managers because MCR can be estimated from high resolution digital imagery using remote sensing techniques. DBH is a common tree dimensional characteristic that is used to quantify tree and stand structure. This research presents MCR/DBH and DBH/MCR relationships for boxelder (Acer negundo L.), sweet pecan (Carya illinoensis (Wang) K.Koch), sugarberry …
Identifying The Factors Distinguishing Timber Sales On Industrial And Non-Industrial Private Forest Lands In Arkansas, Sayeed R. Mehmood, Prabudhda Dahal
Identifying The Factors Distinguishing Timber Sales On Industrial And Non-Industrial Private Forest Lands In Arkansas, Sayeed R. Mehmood, Prabudhda Dahal
Journal of the Arkansas Academy of Science
Although forests provide a wide variety of products and services, timber still continues to be the most valued forest product in the marketplace. More than two-third of the nation's forests are under private control, some are owned by industries (about 10%) while a much larger portion (about 59%) is owned by individuals. This study investigates the differences between timber sales offered by industrial and non-industrial ownerships. A test of means revealed that there is a significant difference between per hectare bid for these 2 types of sales. A logistic regression model was then estimated to identify important factors characterizing this …
