  • Raised Bed Gardening Guide Advantages of Raised Bed Gardening
    RAISED BED GARDENING GUIDE ADVANTAGES OF RAISED BED GARDENING Raised Bed Gardening is an organic growing method which allows you to grow a larger, more plentiful harvest with less cost, in less space, using less water and seeds, and less work than traditional gardens. • Growing your own garden helps families improve their health through better nutrition. • With Raised Garden Beds, plant placement is done differently than in traditional row gardens, allowing you to grow five times as many crops as traditional gardens. • Raised Garden Beds use 20% of the space of single-row gardens. They can be located closer to the house where they will get more attention and care, resulting in a better, easy to manage garden and a more usable harvest. • Because your gardening space is more compact and productive, Raised Garden Beds reduce water usage significantly as you only water the productive area of your garden and not weeds or empty soil. • Raised Garden Beds use specially formulated soil which does not require tillers to break it up, added fertilizers, or weed killers. • The special soil used in Raised Garden Beds is not dug from your existing soil which means it does not contain weed seeds. The soil is not as compact which means if weeds seeds blow in, they are easily removed. SETTING UP YOUR GARDEN WHAT DO I NEED? 1. Lifetime Raised Garden Beds 2. Soil Mix 3. Weed Barrier 4. Seeds or Starts SOIL MIX: VERMICULITE Vermiculite is used to retain moisture in soil. The more coarse the vermiculite the better.

  • Principles of Sustainable Weed Able Weed
    PRINCIPLES OF SUSTAINABLE WEED MANAGEMENT FOR CROPLANDS AGRONOMY SYSTEMS SERIES Abstract: To some extent, weeds are a result of crop production, but to a larger extent they are a consequence of management decisions. Managing croplands according to nature’s principles will reduce weed problems. And while these principles apply to most crops, this publication focuses on agronomic crops such as corn, soybeans, milo, and small grains. The opportunities to address the root causes of weeds are not always readily apparent, and often require some imagination to recognize. Creativity is key to taking advantage of these opportunities and devising sustainable cropping systems that prevent weed problems, rather than using quick-fix approaches. Annual monoculture crop production generally involves tillage that creates conditions hospitable to many weeds. This publication discusses several alternatives to conventional tillage systems, including allelopathy, intercropping, crop rotations, and a weed- free cropping design.

  • Genetic Engineering and Sustainable Crop Disease Management: Opportunities for Case-By-Case Decision-Making
    sustainability Review Genetic Engineering and Sustainable Crop Disease Management: Opportunities for Case-by-Case Decision-Making Paul Vincelli Department of Plant Pathology, 207 Plant Science Building, College of Agriculture, Food and Environment, University of Kentucky, Lexington, KY 40546, USA; [email protected] Academic Editor: Sean Clark Received: 22 March 2016; Accepted: 13 May 2016; Published: 20 May 2016 Abstract: Genetic engineering (GE) offers an expanding array of strategies for enhancing disease resistance of crop plants in sustainable ways, including the potential for reduced pesticide usage. Certain GE applications involve transgenesis, in some cases creating a metabolic pathway novel to the GE crop. In other cases, only cisgenessis is employed. In yet other cases, engineered genetic changes can be so minimal as to be indistinguishable from natural mutations. Thus, GE crops vary substantially and should be evaluated for risks, benefits, and social considerations on a case-by-case basis. Deployment of GE traits should be with an eye towards long-term sustainability; several options are discussed. Selected risks and concerns of GE are also considered, along with genome editing, a technology that greatly expands the capacity of molecular biologists to make more precise and targeted genetic edits. While GE is merely a suite of tools to supplement other breeding techniques, if wisely used, certain GE tools and applications can contribute to sustainability goals. Keywords: biotechnology; GMO (genetically modified organism) 1. Introduction and Background Disease management practices can contribute to sustainability by protecting crop yields, maintaining and improving profitability for crop producers, reducing losses along the distribution chain, and reducing the negative environmental impacts of diseases and their management.

  • Invasive Plants in Your Backyard!
    Invasive Plants In Your Backyard! A Guide to Their Identification and Control new expanded edition Do you know what plants are growing in your yard? Chances are very good that along with your favorite flowers and shrubs, there are non‐native invasives on your property. Non‐native invasives are aggressive exotic plants introduced intentionally for their ornamental value, or accidentally by hitchhiking with people or products. They thrive in our growing conditions, and with no natural enemies have nothing to check their rapid spread. The environmental costs of invasives are great – they crowd out native vegetation and reduce biological diversity, can change how entire ecosystems function, and pose a threat Invasive Morrow’s honeysuckle (S. Leicht, to endangered species. University of Connecticut, bugwood.org) Several organizations in Connecticut are hard at work preventing the spread of invasives, including the Invasive Plant Council, the Invasive Plant Working Group, and the Invasive Plant Atlas of New England. They maintain an official list of invasive and potentially invasive plants, promote invasives eradication, and have helped establish legislation restricting the sale of invasives. Should I be concerned about invasives on my property? Invasive plants can be a major nuisance right in your own backyard. They can kill your favorite trees, show up in your gardens, and overrun your lawn. And, because it can be costly to remove them, they can even lower the value of your property. What’s more, invasive plants can escape to nearby parks, open spaces and natural areas. What should I do if there are invasives on my property? If you find invasive plants on your property they should be removed before the infestation worsens.

Caulkins H. Guyford Stever Professor of Operations Research Carnegie Mellon University Heinz College & Qatar Campus RAND, Drug Policy Research Center Abstract This paper tries to estimate post-legalization production costs for indoor and outdoor cannabis cultivation as well as parallel estimates for processing costs. Commercial production for general use is not legal anywhere. Hence, this is an exercise in inference based on imperfect analogs supplemented by spare and unsatisfactory data of uncertain provenance. While some parameters are well grounded, many come from the gray literature and/or conversations with others making similar estimates, marijuana growers, and farmers of conventional goods. Hence, this exercise should be taken with more than a few grains of salt. Nevertheless, to the extent that the results are even approximately correct, they suggest that wholesale prices after legalization could be dramatically lower than they are today, quite possibly a full order of magnitude lower than are current prices.

Materials: Pressure treated lumber vs. conventional lumber: Pressure treated lumber manufactured since 2004 no longer use a form of arsenic to protect the lumber from insects. It is significantly less expensive than most other lumber available at the “Big Box” stores. If you wish to stain or paint treated lumber, you may have to wait up to six months for it to dry enough to stain or paint. Use care when sawing pressure treated lumber; wear an appropriate respirator and throw away sawdust and left over scraps in the trash. Do not try to recycle pressure treated lumber in a compost bin. Conventional lumber has either natural resistance to pests and fungus (redwood, cedar and cypress) or no resistance to pests and fungus (pine, oak, and poplar). Staining and painting may be necessary for the wood to last more than a couple of years as a garden bed.
