New Bale Unroller Design Proves Effective

John Wilhoit and Timothy Coolong from the University of Kentucky have introduced a new technology that can make the application of organic mulches more efficient. The team altered a conventional round-bale unroller and designed experiments to document its efficiency. “We modified an unroller so that the new design would be offset a sufficient distance for […]

Vetch Cover Crop Recommended for Organic Zucchini

In a new study, the popular cover crop vetch (Vicia sativa L.) was used in a two-year field experiment designed to determine the effects on organic zucchini yield and quality of vetch residue management strategies incorporating green manure using a roller-crimper (RC) and organic fertilizers. To allow for timely crop rotation in organic farming, the […]

Weed Control with Flame Cultivation

University of Massachusetts scientists designed a study using flame cultivation (FC) techniques for weed control in cranberry crops. The results, published in HortScience, show promise for integrating the weed control technique into “certain situations,” including organic farming. The team tested three types of handheld propane torches and varying exposure times on several species of perennial […]

Glyphosate-Resistant Pigweed Project

Palmer amaranth, commonly known as pigweed, is one of the most common — and problematic — weeds in soybean crops across the southern United States. Because it is difficult to control, it is best to combat the weed before it emerges. The journal Weed Technology offers results of field tests of resistant Palmer amaranth in […]
