Resource, Environment and Energy Considerations for Maine Food Security in 2050 and Beyond

This article discusses some of the expensive “externalities” produced by industrial agriculture and fishing. These include impaired watershed quality, soil degradation, pollution, reduction in biodiversity, and impacts on human health. The article also includes a discussion of transgenic crops and how these relate to sustainable agricultur

Nurse Cropping in Potato Systems

In the summer of 2016, a study was conducted at the Rogers Farm in Stillwater, Maine to study the effect of short-term nurse crops on potato yield and quality. The study was designed as a randomized complete block design with six replications. The study compared two sowing rates (winter rye at 100 vs. 200 lbs/ac) to 20 lbs of annual ryegrass or a check plot (no nurse crop). In addition, each of the winter rye treatments was either killed with an herbicide prior to one-pass hilling or just hilled. To address the question of how long to grow a NC, WR treatments were allowed to grow either three weeks or four weeks prior to being incorporated.https://digitalcommons.library.umaine.edu/extension_ag/1008/thumbnail.jp

Historical Perspectives on Resource Use in Food Systems

No one would deny that industrial agriculture and fishing have been highly productive—but at what cost? This article explores the historical development and contemporary impact of food production on the environment, availability of water and other resources, energy, food safety, and even our waistline

Use of EndoMaxx mycorrhizal seed treatment to improve potato production in Maine

With the increasing cost of fertilizer and the ever-decreasing supply of apatite worldwide, improving phosphorus (P) uptake should be a goal for all producers. Due to our high levels of iron and aluminum oxides in Maine soils, P efficiency is very poor. As a result, potato farmers tend to over apply P to ensure that their crop will have adequate P. Over time, this has led to increasing plant available soil test P levels. I recently requested the Maine Soil Test Lab director for potato soil tests over the past ten years. The percentage of soils testing above 40 lbs/ac has grown steadily over the past 10 years (Figure 1). Mycorrhizal fungi have long been used as a means to effectively improve P absorption of perennial plants. Less work has been done evaluating these for annual crops. With funding from the Valent corporation, we were able to evaluate one such mycorrhizal fungi product, EndoMaxx, to see if it might improve P uptake, yield and quality of potatoes.https://digitalcommons.library.umaine.edu/extension_ag/1007/thumbnail.jp

Effecting Land-Use Changes Through Education and Implementation: Assessing the Effectiveness of the Watershed Stewards Program

Over the past 7 years, the University of Maine Cooperative Extension (UMCE) has conducted the Watershed Stewards Program (WSP), a 20-hour lake education and implementation program. To assess program effectiveness, we studied whether our program significantly improved program participant knowledge level over non-participants through quantitative and qualitative measures. An objective, 15-question test was administered to program participants and other people living in these lake watersheds. Stewards scored significantly (23%) higher on the objective test than those who had not been involved in the program. Program participants qualitatively demonstrated much more involvement with lake governance, implementation efforts, and related activities

Word Cloud Analysis of Early Adopter No-Till Farmer Interviews

We interviewed early adopter no-till farmers in the New England region to assess why they changed tillage practices and what the perceived advantages and disadvantages of doing so were. We then generated word clouds from answers to key interview questions to convey the farmers\u27 experiences. Most of these innovators were influenced to convert to no-till by the success of other exemplary farmers. Advantages noted included reductions in production time and fuel use. The greatest perceived disadvantage was pest management issues caused by cover crop residues. Yield losses were not mentioned, and many of the farmers experienced increased yields. Our findings suggest that Extension staff can increase adoption of new production techniques by identifying and conveying experiences of key farmer leaders

Defining a Paradigm for the Dissemination of Health Information to Immigrant Populations at the Fletcher Free Library

Abstract: In recent years, the surge of refugee families to the greater Burlington area has lead to a significant increase in the minority population of the city. The Fletcher Free Library (FFL) represents a potential health information resource for this population; it is, however, little utilized. Our project sought to target one of these minority populations, the Somali Bantu, and to diminish the barriers to the use of the FFL’s resources within the Somali population itself. To reduce barriers to access of health information by the Somali Bantu population, we educated the FFl’s reference librarians on Somali culture, developed a compendium of health information in both English and Somali for inclusion within the library’s collection, and staged a one-day intervention at the Community Health Center of Burlington to present the FFL as a potential source of health information for refugee populations. Somali Bantu use of the library, as well as reference librarian confidence in serving this minority population,was objectively assessed via pre- and post-interventional surveys.https://scholarworks.uvm.edu/comphp_gallery/1022/thumbnail.jp
