Comparing Some Key Attributes of Sugar Maple (Acer Saccharum Marsh) and Black Maple ( Acer Nigrum Michx)
The purpose of this article is to shed some light on important and often observed differences between Sugar Maple and Black Maple, and to discuss the comparative sweetness of their sap.
Limitations in the Use of Ozone to Disinfect Maple Sap
This article reports on experiments to determine the usefulness of ozone as a method of reducing the microbial levels in maple sap.
Long-term calcium addition increases growth release, wound closure, and health of sugar maple (Acer saccharum) trees at the Hubbard Brook Experimental Forest
We surveyed and wounded forest-grown sugar maple (Acer sacchamm Marsh.) trees in a long-term, replicated Ca manipulation study at the Hubbard Brook Experimental Forest in New Hampshire, USA. Plots received applications of Ca (to boost Ca availability above depleted ambient levels) or A1 (to compete with Ca uptake and further reduce Ca availability). We found significantly greater total foliar and membrane-associated Ca in foliage of trees in plots fertilized with Ca when compared with trees from Al-addition and control plots (P = 0.005).
Equating Syrup Price to Sap Price
In fairness to both sap producers and sap purchasers, the price of maple sap should be directly related to the price of maple syrup. This chart helps calcuate that value.
Sugar Maple Tree Improvement Program
Maple producers and rural landowners throughout the maple syrup producing regions of the Northeast have expressed interest in acquiring improved sugar maple seedings for future sap production. A sugar maple tree improvement program for high sap concentration began in the 1960s under the direction of the USDA Forest Service.
Maple Sap Concentration Processes and Variable Cost of Different Fuels
A spreadsheet to calculate costs of operating evaporators with a range of fuel types.
Sanitation of Maple Tubing Systems: Second Year of Testing – Report on the Season 1999 Tests in the College D’Alfred Maple Bush
Report on the microbial load of sap collected through plastic tubing systems.
A Survey of Sugar Maple Nutrition in Vermont and Its Implications for the Fertilization of Sugar Maple Stands
Can fertilization of sugar maple stands lead to increased diameter growth, better crown conditions, and/or added sugar production? The effectiveness of fertilization depends in large part on soil nutrition.
Update on the Maple Tubing Sanitation Research in Ontario
In the spring of 1998, a research project was initiated to develop alternative methods for maple produces using plastic tubing systems. Although the results are only preliminary, the development of alternative sanitation methods that may reduce reliance on chlorine is looking very promising.
