Tb136: Methodology Development For Study Of Root Influences On Nitrogen Mineralization, M. S. Erich
Technical Bulletins
The current study was designed to explore a particular set of methodologies for addressing the question of whether plant root growth affects the rate of N mineralization. Specifically, the experimental design involved supplying plants with only organic N as manure and no nitrate. A highly sandy growing medium was used in an attempt to prevent overly wet conditions in the pots. In addition, instead of only comparing planted and unplanted pots, four different planting densities (0, 1, 2, 3 plants per pot ) were used as treatments.

The objective of this study was to compare several commonly used lime requirement tests and soil capacity factors for their ability to predict pH change following wood-ash amendment. The ability to predict pH change is important because it is one of the criteria used to prescribe rates of ash amendment to forest soils.
