Other claims from this paper (15)
- Association Tree size and distance from boles had no effect on biomass or nutrient concentrations and amounts in understory vegetation.
- Association Above-ground tree biomass of western juniper increased with maturity.
- Observation Biomass of western juniper accumulated rapidly, 22.3 kg per tree per year, between size classes 2 and 3.
- Observation Foliage comprised 41% of tree biomass in class 1 western juniper trees.
- Observation Foliage decreased to 15% of tree biomass in class 5 western juniper trees.
- Observation Percentage of tree biomass in boles and live branches of western juniper increased from 29 to 47%.
- Association Nitrogen (N) amounts in western juniper trees increased from size class 1 to class 5.
- Association Phosphorus (P) amounts in western juniper trees increased from size class 1 to class 5.
- Association Sulfur (S) amounts in western juniper trees increased from size class 1 to class 5.
- Observation In open systems, soil held 89.9 to 99.8% of entire-system N, P and S.
- Association Corg, N and S in aboveground biomass of tree systems increased with increasing tree maturity.
- Association P in aboveground biomass of tree systems did not change with increasing tree maturity.
- Observation For the most mature trees, 30% of total system N was allocated to the organic layer and trees.
- Observation For the most mature trees, 78% of total system S was allocated to the organic layer and trees.
- Observation For the most mature trees, 5% of total system P was allocated to the organic layer and trees.
