Long-Term Effects of Forest Liming on Soil, Soil Leachate, and Foliage Chemistry in Northern Pennsylvania

Sugar maple (Acer saccharum Marsh.) decline disease, decreased growth, and regeneration failure have been related to a low supply of Ca and Mg. There is increased interest in augmenting cation availability via liming, but there is little information on the amounts of lime required and the longevity of the lime treatment. A single application of 22.4 Mg ha-1 of dolomitic limestone in 1985 at four forested sites in Potter County, PA has shown that soil, soil water, and sugar maple foliage chemistry are significantly altered by liming and the changes in soils and foliage persist as long as 21-yr post-treatment. By 2001, only 3 kg ha-1 of lime remained undissolved while increases in exchangeable Ca and Mg, and pH continued through 2006 at depths up to 35 to 45 cm.

Long-term impact of liming on growth and vigor of northern hardwoods

Sugar maple (Acer saccharum Marsh.) is a keystone species in the northern hardwood forest, and decline episodes have negatively affected the growth and health of sugar maple in portions of its range over the past 50+ years. Crown health, growth, survival, and flower and seed production of sugar maple were negatively affected by a widespread decline event in the mid-1980s on the unglaciated Allegheny Plateau in northern Pennsylvania. A long-term liming study was initiated in 1985 to evaluate responses to a one-time application of 22.4 MgáhaÐ1 of dolomitic limestone in four northern hardwood stands.

Maintaining a Healthy Sugarbush

A sugarbush is a special type of woodland. Woodlands include a complex mixture of natural processes and attributes such as soil type, elevation, tree species, types of wildlife, history of use, tree age and more. Foresters can help maple producers gain an in-depth understanding of these factors to achieve a healthy and productivity sugarbush, but there are several steps a maple producer can take on their own.

Making Cornell Maple Syrup

In the Spring, maple trees begin to move sap up from their roots. At the Arnot forest, this sap is collected and then boiled down to produce maple syrup. In this video, Prof. Brian Chabot, tells us about the process and we see how maple syrup is made.

Making Maple Syrup in a Land of Funnel Cakes and Pulled Pork

Making maple syrup in the mild climate of southern Illinois is lesspredictable and more work. The sap seasons are longer, there is an almost certain need to freshen the tap holes, and the freeze-thaw cycles are less predictable.

Management Strategies for Invasive Plants in the Sugarbush

There are multiple approaches to treat or otherwise kill invasive plants that that the maple producer wants to control. The best treatment in one situation may not be best in another situation. Methods of treatment are typically either mechanical or chemical. Both methods have advantages and disadvantages depending on the circumstances.
