- Description:
- Three controlled-release fertilizers (fast release (FR), moderate release (MR) and slow release (SR) were incorporated in the growing media at rates of 0.8, 1.6 or 3.2 grams per seedling at the time of sowing as supplements to nursery supplied soluble fertilizer. Effects on seedling biomass allocation of the '160/90' container ponderosa pine (Pinus ponderosa Doug. ex Laws) were evaluated in the field. Two years after outplanting, fertilization significantly increased foliage, stem, root and total biomass of ponderosa pine seedlings, but did not change foliage, stem and root dry weight ratios and shoot/root ratios. Fertilization changed height/caliper ratios of ponderosa pine seedlings. For small calipers (>20mm), fertilized seedlings were taller than unfertilized seedlings of the same caliper; however, for larger calipers (>20 mm), fertilized seedlings were shorter than unfertilized seedlings of the same caliper. Caliper was more strongly related to total and component biomass of ponderosa pine than was height. The strong association between caliper and biomass provides an efficient way to measure fertilizer treatment effects on biomass for future studies.
