The focus of this study is direct marketing of produce from an urban market garden. Rather than discussing broad issues of direct marketing, we use a case study to frame the decisions a market gardener is likely to face in developing both production and marketing plans. The garden featured in this study is located in Seattle, Washington, a city…

Phosphorus (P) is the limiting nutrient controlling productivity in most inland freshwater systems. Several materials have been proposed for use to remove excess P from wastewater treatment, including volcanic lapilli and ash (tephra). There is limited data in using tephra as a P filter. There were two objectives of this study: (1) to determine…

Copper fungicides and bactericides are often used in tomato cultivation and can cause toxic Cu levels in soils. In order to combat this, organic matter can be applied to induce chelation reactions and form a soluble complex by which much of the Cu can leach out of the soil profile or be taken up safely by plants. Organic acids such as citric,…

Integrating livestock into a cropping system by allowing ruminant animals to graze cover crops may yield economic and environmental benefits. The effects of grazing on soil physical properties, soil organic matter, nitrogen cycling and agricultural production are presented in this literature review. The review found that grazing cover crops…

Concerns are growing regarding the availability of sustainable energy sources due to a rapidly growing human population and a better understanding of climate change. In recent years, the United States has focused much attention on developing domestic energy sources, which include coal-bed methane (CBM). There are vast deposits of the natural gas…

Spatial and temporal variability of riparian areas, as well as potential impacts from climate change, are concepts that land and water managers and stakeholders need to understand to effectively manage and protect riparian areas. Rapid population growth in the southwestern United States, and multiple-use designation of most riparian areas, makes…

Managing fish resources in the ocean, known as marine fisheries management, often involves disagreement among many groups of people: commercial fishers, recreational anglers, national and local conservationists, and several branches of government. While managing marine fisheries in federal waters, the federal government must rebuild marine fish…

The use of case studies in college courses can increase student engagement with the subject matter and improve analytical, problem-solving, and communication skills. Case studies were introduced in a relatively large (54 students) undergraduate world food and population course at Colorado State University in the spring semester of 2008 and…

A set of publicly available online learning modules was created as an educational supplement to a university extension program. Because the modules created for this program--like many online modules developed as a part of university outreach--are supplementary to programs featuring in-person instruction and hard-copy materials, it is not required…

The notion of risk in relation to food and food production has heightened the need to educate students to effectively deal with risk in relation to decision making from a science-based perspective. Curricula and related materials were developed and adopted to support graduate learning opportunities in risk analysis and decision making as applied…

Forestry higher curricula reform is being debated globally. This study examines the views of students on aspects related to forestry education and the profession, focusing on how these views differ across the study years of a higher education forestry program. The objective of the study was to investigate the differences across study years with…

The purpose of this study was to investigate Turkish primary students' scientific process skills under the theoretical framework of cognitive domain. The sample set consisted of 306 sixth and seventh grade students from public, private, and bussed schools. The Turkish Integrated Process Skill Test was used to measure scientific process skills, and…

Articles from the National Science Teacher Association (NSTA) publications were analyzed to investigate resources available for teachers who want to implement interdisciplinary approaches into the science classroom. All articles in each journal from 2004 through 2008 were read an analyzed; approximately 13% of Science & Children (elementary), 21%…

The purpose of this paper is to analyze in detail the process in which a 5th grade student learned proportion and percent using double number lines and to obtain insights into how his use of those representations supported his learning. A series of lessons were designed and conducted in a class and the whole learning process of one student was…

Mathematics learning and achievement is one area of research that has gained momentum in recent years because of its importance as a subject in the school curriculum and its usefulness as a prerequisite for developing the quantitative and analytical skills. However, studies on factors affecting mathematics achievement in Malaysia are limited both…
