Impact of Process Emissions on Climate Offsets by Different Biochar Production Methods

Agricultural use of biochar is generally considered a sustainable and climate-friendly way to increase farm productivity. These benefits, however, depend on how biochar is produced. I have performed some preliminary calculations for a range of biochar production technologies using published data for methane emission and biochar carbon efficiency that suggest that most biochar production approaches […]

Tallgrass Prairie in Central Washington: Establishing Warm-Season Perennial Grasses on Irrigated Pasture

Warm-season perennial grasses (WSG) native to the American tallgrass prairie have tremendous production potential under irrigation. Central Washington irrigated pastures occupied by cool-season grasses exhibit dramatically slower growth during meteorological summer. Grazing land is a scarce resource in Washington State for which there is high demand. Further, many ranchers’ business growth is limited by unavailability […]

Precision application of organic amendments for improved soil quality in replant orchards

During apple orchard renewal, Apple Replant Disease (ARD) and soil degradation can lead to inconsistent infill vigor and uneven fruit production. Brassica seed meal is an effective organic amendment for suppressing ARD and improving soil fertility in new plantings, but it is expensive and not necessary for orchard areas that do not express ARD. We […]
