Systematic method for rating soil quality of conventional, organic, and integrated apple orchards in Washington State

J.D. Glover, J.P. Reganold, P.K. Andrews. 2000. Agriculture, Ecosystems, and Environment 80:29-45.

Agricultural Efficiency – WSU Extension Energy Program webpage

The WSU Energy Program offers information, education and tools to help reduce energy use in the agriculture sector. Farmers and ranchers use energy directly to operate machinery or equipment and to heat, cool, light and ventilate buildings. They also use energy indirectly through fertilizers and other products that are integral to production or processing.

Alternatives to Fumigation for Control of Apple Replant Disease in Washington State Orchards

Granatstein, D. & M. Mazzola.

Effects of Biodynamic Preparations on Compost Development.

Carpenter-Boggs, L., J. Reganold, A. Kennedy. 2000. Biol. Agric. Hortic. 17:313-328. The study showed that additions of herbal biodynamic preparations to compost piles resulted in consistently higher pile temperature during active composting, and higher nitrate levels and lower dehydrogenase:carbon dioxide release in mature compost samples, compared to the control.

Organic and Biodynamic Management: Effects on Soil Biology

Carpenter-Boggs, L., A.C. Kennedy, J.P. Reganold. 2000. Soil Sci. Soc. Am. J. 64:1651-1659.

Compost quality: new threats from persistent herbicides

Bezdicek, David, Mary Fauci, Dan Caldwell, and Rick Finch. 2000. Agrichem and Environ News 174: 9-13. WSU Extension.

The Future of Agricultural Composting and Compost Use

The third and final video produced by the Compost Education and Resources for Western Agriculture (CERWA) project. Produced in 2000, the video looks at future trends that could affect agricultural composting and compost use, including composting systems and regulations, and marketing of compost products.
