A new study contains valuable recommendations that can inform container nursery fertilization practices in the northeastern United States. In this region, most nursery substrates are comprised primarily of pine bark and sphagnum moss, with minor additions of other components such as compost, sand, gravel, and humus. According to the study authors, cation exchange capacity—an important factor that affects nutrient leaching from pine bark substrates, pH buffering, and drift over the course of crop production—-had not been adequately studied for pine bark.
