Aquaponics

In science & nature on May 1, 2011 at 7:30 am

A system of agriculture involving the simultaneous cultivation of plants and aquatic animals such as fish in a symbiotic environment. In a traditional aquaculture, animal effluents accumulate in the water, increasing toxicity for the fish. It is a closed system in that the only water introduced into the system is done to replace the amount lost by evaporation. No chemical fertilizers or insecticides are used. In an Aquaponics system the water from the fish is pumped through a filtration system which consists of a sump to collect the solids and a bio filter which, through the use of helpful bacteria, turns the ammonia into nitrites which is then turned into nitrates, fertilizer. This water is then pumped to a hydroponic system where the nitrates are filtered out by the plants as vital nutrients. Then to complete the cycle, the clean water is then circulated back to the aquaculture system. The term aquaponics is a portmanteau of the terms aquaculture and hydroponic. Aquaponic systems vary in size from small indoor or outdoor units to large commercial operations. The systems are most always fresh water, as salt water systems are not very plausible because of the lack of edible vegetation that can be produced in saltwater.

Permaculture

In science & nature on May 1, 2011 at 7:18 am

Permaculture is an approach to designing human settlements and agricultural systems that are modeled on the relationships found in natural ecologies. Permaculture is sustainable land use design. This is based on ecological and biological principles, often using patterns that occur in nature to maximize effect and minimize work. Permaculture aims to create stable, productive systems that provide for human needs, harmoniously integrating the land with its inhabitants. The ecological processes of plants, animals, their nutrient cycles, climatic factors and weather cycles are all part of the picture. Inhabitants’ needs are provided for using proven technologies for food, energy, shelter and infrastructure. Elements in a system are viewed in relationship to other elements, where the outputs of one element become the inputs of another. Within a Permaculture system, work is minimized, “wastes” become resources, productivity and yields increase, and environments are restored. Permaculture principles can be applied to any environment, at any scale from dense urban settlements to individual homes, from farms to entire regions.

Selling Like Hot Cakes

In words & phrases on March 1, 2011 at 10:12 am

“Hot cakes cooked in bear grease or pork lard were popular from earliest times in American. First made of cornmeal, the griddle cakes or pancakes were of course best when served piping hot and were often sold at church benefits, fairs, and other functions. So popular were they that by the beginning of the 19th century ‘to sell like hot cakes’ was a familiar expression for anything that sold very quickly effortlessly, and in quantity.” From “Encyclopedia of Word and Phrase Origins” by Robert Hendrickson (Facts on File, New York, 1997)
