SL-240: Improving Citrus Nitrogen Uptake Efficiency: Understanding Citrus Nitrogen Requirements

Figure 2. As tree size (canopy volume) increases, biomass (tree dry weight) is accumulated in both below ground and above ground plant parts similar to nitrogen accumulation. The above ground portions (trunk, scaffold branches, twigs, and leaves) accumulate more dry weight for a given tree size than below ground plant portions (taproot, lateral roots, and fibrous roots).
