Development of Nutrient Status in Forest Soils Item Info

Most of the elements which are considered essential for plant growth come from the soil. The inland northwest region is very young geologically, and therefore rock type strongly influences soil characteristics and forest nutrient status. A number of significant geologic events in the history of the inland northwest result in the predominance of a few common rock types in the area, including basalts, granites, metasedimentary rocks and glacial deposits. Average geochemistry of rocks collected from Intermountain Forest Tree Nutrition Cooperative (IFTNC) research sites show that basalts contain the greatest percent by weight of elements which are considered mineral nutrients, followed by granites and then metasedimentary rocks. Mineralogical analyses of the same rocks show that basalts contain the most weatherable minerals, followed by granites and then metasedimentary rocks. These findings are supported by a geochemical-based weathering potential index calculated for each rock type. Glacial deposits typically reflect a wide variety of characteristics due to the variety of rock types comprising such deposits. Climate, biota, time and topography also interact with geology to influence soil formation in the inland northwest.
