Understory Management in Organic Orchards

Trials examined weed control, soil quality, tree nutrition, and water use. Also monitored for voles, and testing potential for mulch to host nematodes for control of codling moth larvae. David Granatstein, WSU CSANR, Wenatchee.

Greenhouse Gases and Agriculture: Where Does Organic Farming Fit?

Agriculture can be both a source and a sink for greenhouse gases. In this webinar, the presenters discuss these roles of agriculture, how management affects them, and ways in which organic farming systems in particular may influence greenhouse gases.

Climate Friendly Farming Final Report: Improving the Carbon Footprint of Agriculture in the Pacific Northwest

The WSU Center for Sustaining Agriculture & Natural Resources established the Climate Friendly Farming Project in 2003 with an initial grant from the Paul G. Allen Family Foundation. This report represents the culmination of research and assessment of the potential for improved management and technology deployment to reduce agricultural greenhouse gas emissions in the Pacific Northwest.

Biochar and Pyrolysis: Renewable Soil Carbon and Energy – December 2009

Article in Sustaining the Pacific Northwest Newsletter

Organic Waste to Resources Research and Pilot Project Report: Use of Biochar from the Pyrolysis of Waste Organic Material as a Soil Amendment

David Granatstein, Chad Kruger, Hal Collins, Manuel Garcia-Perez, and Jonathan Yoder, September 2009. Biochars from different feedstocks were tested on five soils. Biochars on all soil types increased soil C. Biochar C was stable in soil with mean residence times estimated in the hundreds of years. Soil nitrate levels were reduced with increasing biochar rate perhaps due to ammonium adsorption. Biochar did not accelerate loss of indigenous organic matter through the ‘priming effect.′ Biochars raised soil pH, but did not lead to consistent plant growth improvements.
