Organic apple orchards benefit from green compost applications

FAYETTEVILLE, AR In traditional apple orchards, effective management practices rely on two interrelated components: finding ways to manage competitive vegetation under the trees, and supplying important supplemental nutrition to trees. These factors are further complicated in organic management systems where limited tools are available, and producers need to meet the stringent soil fertility and crop nutrient management standards of the National Organic Program. University of Arkansas scientists published a study that includes recommendations for the use of various groundcover management systems for apple orchard floors. They say that selected management systems can improve soil quality in organically managed apple orchards.

Curt Rom, corresponding author of the study (published in HortScience), explained that orchards established on the weathered, acidic mineral soils in the Ozark Highlands must be strategically managed in order to meet the trees' nutritional requirements. "A common characteristic of Ozark Highland soils is a relatively low soil organic matter concentration, a condition that can have detrimental effects on orchard productivity," Rom said. A cross-disciplinary research team studied the impacts of groundcover management systems and nutrient source on soil characteristics, tree health and productivity, and insect, disease, and weed management. The experiments were performed in an organically managed apple orchard that was established in 2006 and continues today at the University of Arkansas' Agricultural Research and Extension Center in Fayetteville.

The researchers evaluated several under tree, in-row groundcover management systems, including shredded paper, wood chips, municipal green compost, and mow-blow. They also tested various nutrient sources (non-fertilized control, composted poultry litter, and pelletized organic commercial fertilizer). The groundcover systems and nutrients were analyzed for their respective ef
