This brochure is intended to help landowners and maple producers evaluate the nutrition of maple stands, and determine whether fertilization might be appropriate. There is an emphasis on learning some of the plants in your woods, as these are often valuable indicators of site quality, and are in many cases easier to interpret than chemical analyses of soil or leaves.
New filter presses do not always include a complete set of instructions and the proper procedures in using a filter press are not always apparent. This publication is meant to provide guidelines for the proper use of plate filter presses.

In this article we describe the effects of fertilization and liming on sugar production in maple stands.
The goal of this project was to examine the effects of liming and fertilization on tree physiology, growth and sugar production of a moderately fertile maple stand. In this first report, we describe, in general terms, the study area, treatments, and results of liming and fertilization on tree physiology and growth.
Although maple dieback has received considerable recent attention in the Northeast, little has been reported about the relationship between sap sugar yield and crown health or crown nutrition. We measured sap sugar concentration (sweetness) in six northern Vermont maple stands in the springs of 1990-1992, and sap volume yield from tapholes at one stand in 1991. The stands differed in average crown dieback, canopy transparency, density, and mean dbh, as well as cation exchange capacity (CEC) of upper soil horizons.
