COMPARISION BETWEEN HYDROPONIC and SOIL SYSTEMS for GROWING STRAWBERRIES in a GREENHOUSE Chenin Treftz, Stanley T

Omaye Agriculture, Nutrition and Veterinary Sciences Department and Environmental Sciences and Health Graduate Program, University of Nevada, Reno, USA. A B S T R A C T Consumption of strawberries has been asserted to have many health promoting bioactive compounds including antioxidants. Growing fruits and vegetables hydroponically represent a possible opportunity towards sustainable crop production; it would be beneficial to examine the feasibility and the potential ability to replace soil systems for growing strawberries. Unlike leafy greens, the root structures, stalk, and fruit are more complex and require more physical support. In this study, hydroponic strawberries were higher in terms of fruit yield and plant survival rate. In soil-grown strawberries, the overall mass was significantly higher by 23%, but there was a larger variation of fruit size indicated by a large standard deviation. Startup costs for growing strawberries in hydroponic systems can be more than soil systems. Growing strawberries in hydroponic systems are feasible, at reasonable cost and more sustainable compared to traditionally soil grown systems. Future research should investigate various hydroponic growing methods and the feasibility of growing at the commercial level. Keywords: Hydroponic, greenhouse, strawberry, feasibility, technology.

Technologies to Sustain Forest Resources
Technologies To Sustain Forest Resources March 1984 OTA-F-515 NTIS order #PB92-182104 Recommended Citation: Technologies to Sustain Tropical Forest Resources (Washington, D. C.: U.S. Congress, Office of Technology Assessment, OTA-F-214, March 1984). Library of Congress Catalog Card Number 84-601018 For sale by the Superintendent of Documents U.S. Government Printing Office, Washington, D.C. 20402 Foreword The United States has a stake in the sustained economic development of tropical nations for humanitarian, political, and economic reasons. To a great extent, the development of these nations depends on increasing production from their poten- tially renewable soil, forest, and water resources. But tropical forest resources, which cover nearly one-half of the tropical nations’ land, are being consumed at a rate that may make them nonrenewable. They are exploited for timber and cleared for pasture and cropland with little regard for their abilities to produce—in a long- term sustainable fashion—important goods, maintain soil productivity, regulate water regimes, or regenerate themselves. Much of the recent deforestation occurs where the new land uses cannot be sustained and it causes productivity losses that tropical nations and the world can ill afford. International recognition of the importance of tropical forests, and efforts to sustain the productivity of these resources, have increased significantly in the last decade. In 1980, the House of Representatives Committee on Foreign Affairs, Sub- committee on International Organizations, held hearings on tropical deforestation. The committee then requested the Office of Technology Assessment (OTA) to con- duct a more thorough assessment of the problem, the technologies that could help sustain tropical forest resources, and possible options for Congress. -
Observe and Replicate Natural Patterns
THE PERMACULTURE ETHICS Care of Earth Care of Humans Share the Surplus Respect Intrinsic Value THE PRINCIPLES OF PERMACULTURE from Bill Mollison & David Holmgren Observe and Interact The primary design tool is the designer. Beauty is in the eye of the beholder. Observation is a short way of saying, “Noticing the information coming from all your senses as they experience and interact with your environment, both inner and outer.” The root of this principle is the willingness to begin designing a culture based on co-creation with Nature, while acknowledging the limitations of our present cultural norm of separation from Nature. It is the willingness to Dance with Nature, learning when to interfere, when not to; learning where limitations and abundances exist, and when; and how to intermesh our human-ness into an ecosystem to meet our needs and help it work better for All. OBSERVATION PRACTICES: sit spot, meditation, breathing awareness, journaling, Nature Walks [learning about the flora and fauna that live around you], Herb Walks [learning about wild edibles and medicinals], learning tracking/hunting skills, learning about the movement of the constellations and the moon. Obtain a Yield You can’t work on an empty stomach. [and neither can anyone else] Definition of system yield: System yield is the sum total of surplus energy produced by, stored, conserved, reused or converted by the design. Energy is in surplus once the system itself has available all it needs for growth, reproduction and maintenance. As PC designers, we are creating “cultivated ecosystems” – cultivated to produce a yield of food, shelter, fiber, medicine, or other product/service useful to humans. -
