dc.description.abstract | One of the biggest challenges to organic agricultural production and herbicide resistant crops in industrialized
countries today is the non-chemical control of weed plants. Studies of new tools and methods for weed control have been
motivated by an increased consumer demand for organic produce and consumer and regulatory demands for a reduction
in environmentally harmful herbicide use. The objective of this study is to assess different agricultural residues as gritty
weed-abrading materials that are delivered through condensed-air machinery. This is a new weed control technology
based on highly-directed air-propelled, innocuous, abrasive grit. Laboratory equipment was designed to calculate the
angle of repose of seven different agricultural residues (crushed olive seed, walnut shell, maize cob, poultry manure,
soybean seed, almond shell and grape seed). Color, digital, high-speed computer vision analysis of the motion and energy
of the air-propelled particles was conducted. The high-speed video analysis determined the capability of each grit to
damage a reference surface and kill weeds (species of Amaranthus, Centaurea, and Chenopodium) at different growth
stages. A preliminary laboratory trial showed that walnut shell grit has great potential to damage/break the reference
surface when it was propelled at 600, 700 and 800 kPa air pressure. Abrasive-weeding reduced final weed biomass by
80% compared with the weedy control at early growth stages. Field research tests are needed in different cropping
systems to improve the technical and economic efficiency of this novel system before on-farm adoption. | es |
