Aquarium Aquaponics As I mentioned in another aquaponics post, I am planning to put together my own small aquaponics system for fun, and of course to see if I can get it to work properly. I’ve always been fascinated with both hydroponics and aquatic biology – among numerous other related topics – so it’s only natural (no pun intended – haha) that I would gravitate towards aquaponics. For those of you unfamiliar with the term, aquaponics is simply a combination of aquaculture and hydroponics. Water is pumped from fish tanks to grow beds where plants (typically some sort of edible produce) take advantage of the nutrient rich water. The plants and gravel (or whatever growth media you use) serve to filter the water before it eventually ends up back in the fish tanks. For my experimental system I will simply be periodically pumping water from a small aquarium into a homemade grow bed, then allowing it to drain back into the fish tank – something similar to my ‘artist’s rendtion’ up above.

Introduction to Silvicultural Systems Silvicultural systems are the essence of a silviculture prescription, providing a long-term planning perspective at the stand level and a foundation for building aprescription. They are legislated in the Forest Practices Code of British Columbia Act and the regulations and standards enabled by the Code. A well-designed silvicultural system is a complex integration of both the art and science of forestry, and reflects an understanding of ecological relationships, long-term desires of the landowner, operational realities, and a creative spirit of innovation and discovery. The first challenge for practitioners inexperienced with various silvicultural systems is to determine the full range of choices available, and to sort through the confusing use and misuse of terminology. Note that this publication is only intended to ground you in the fundamental silvicultural systems concepts. ObjectivesThe general objectives of this workbook are: This workbook is divided into two parts.

Keyhole Gardens Keyhole Gardens First made popular in Africa, keyhole gardens are catching on in Texas and other hot, dry places. Keyhole gardens hold moisture and nutrients due to an active compost pile placed in the center of a round bed. Although most helpful in hot and dry locations a keyhole garden will improve growing conditions in just about any climate. From a bird's eye view the garden is shaped as a keyhole. Keyhole Garden in Central Texas, Deb Tolman uses keyhole gardens as the main source of her own food supply, and is working on ways to keep them producing throughout multiple seasons and conditions.

Taillis fureté Le taillis simple se caractérise par la coupe, appelée recépage, des arbres au ras du sol à intervalles réguliers, de 10 à 40 ans, qui varient selon la vitalité des souches (révolution du taillis) et la nature des produits que l'on désire produire. Le plus connu est le taillis de châtaigniers qui sert à fabriquer les parquets. Le taillis simple a un caractère économique. Les souches produisent un bouquet de plusieurs rejets, à développement très rapide, appelé cépée. Ces rejets sont issus soit de bourgeons " préventifs " qui étaient jusque-là dormants en dessous de la section, soit de bourgeons " adventifs " qui se forment à la périphérie de la section. Le taillis fureté ou furetage se caractérise par la taille des arbres à des hauteurs désirées et choisies par le jardinier, le plus souvent, pour assurer des transitions esthétiques, notamment en lisière des bois.
Coppicing - A Lost Art Revisited - Verge Permaculture Coppicing has always been interesting to me as a wood production system (fuel, timber) because it uses trees that can be cut perpetually. In other words, the tree is cut and grows back. This is quite different from the type of forestry we practice here in Canada with spruce, fir, and pine trees. These conifers are cut once and then die. Here is a great Wikipedia definition on coppicing: In Canada we can grow a number of different trees that can be cut and grow back. Here is a great video on Coppicing from Britain. In addition to fuel and timber coppice systems can be used for basketry, propagation, mulch and fodder. In Ohaton in Camrose County, Alberta, they are using willow to clean up their waste water from a lagoon while growing a feed stock for producing heat for the municipality. Dave Jake and Mark Krawczyk are currently working on a book on Coppice Agroforestry which, if it is anything like his last book Edible Forest Gardens Vols I & II, will be amazing!
Application Architecture Guide - Chapter 1 - Fundamentals of Application Architecture - Guidance Share From Guidance Share Note - The patterns & practices Microsoft Application Architecture Guide, 2nd Edition is now live at - J.D. Objectives Learn the fundamental concepts of application architecture. Overview Application architecture is the process of defining a structured solution that meets all of the technical and operational requirements, while optimizing common quality attributes such as performance, security, and manageability. This chapter lays a foundation for practical application architecture. What Is Application Architecture? Software architecture is often defined as the structure or structures of a system. Kruchten, Booch, Bittner, and Reitman on Architecture Philippe Kruchten, Grady Booch, Kurt Bittner, and Rich Reitman derived and refined a definition of architecture based on work by Mary Shaw and David Garlan (Shaw and Garlan 1996). Fowler on Architecture The highest-level breakdown of a system into its parts.
