Montana Nutrition Guidelines By Rock Type Item Info

Nutrition guidelines for use in conjunction with current digital geology for Montana State. This document was prepared as a guideline for foresters to use in determining appropriate nutrient management strategies for forest stands on various rock types in forests of western Montana. Geologic maps provided through the Montana Bureau of Mines and Geology (MBMG) and the United States Geological Survey (USGS) were utilized in the development of these guidelines. The digital maps currently available for the state of Montana are available on the MBMG website at http://www.mbmg.mtech.edu/stmap.htm. For this document we utilized the Kalispell, Western Half of Cut Bank, Wallace, Choteau and Dillon 1:250K maps from the USGS, and the Wallace, Missoula West, Hamilton, Butte, Leodore and Lima 1:100K maps and Butte 1:250K map provided by the MBMG. A lookup table for each individual map accompanies this 'Guidelines by Rock Type' document, and may be joined to the respective digital geology map attribute table to assign the IFTNC categorization to the individual map units. A total of 516 map units identifying various rock types were identified on the eleven maps included in this report. Each unit was assigned to one of four categories and 47 subcategories for purposes of nutrition guideline recommendations. The following section of the report discusses a little about the lithology and expected weathering behavior of each rock, and provides some nutrient management strategies for each rock category and subcategory. These guidelines are based on our current state of knowledge regarding rocks and forest growth. Our information on fertilization response for Montana forest types is currently very limited; therefore the nutrient management recommendations will be conservative and should not be viewed as absolute. We fully expect these guidelines to be further refined with additional experience and experimentation in Montana.
