Biomass fly ash as foliar fertilizer for hybrid aspen trees: nutrient uptake, growth response, and compatibility with nitrogen fertilizer.
Biomass ash is an important and potentially useful by-product of the bioenergy industry. As a "proof of concept" for using biomass fly ash as a foliar fertilizer, we tested (i) whether the nutrients in the ash were absorbed by hybrid aspen trees, (ii) whether the ash affected tree growth, and (iii) whether the ash was compatible with nitrogen foliar...

Regional variation in growth response of Coastal Douglas-fir to nitrogen fertilizer in the Pacific Northwest.
Hypothesis testing for differences in growth responses among physiographic strata, thinning levels, and fertilizer dosage levels resulted in a set of empirical models for predicting volume increment response of even aged coastal Douglas-fir to nitrogen fertilizer. Absolute and percent responses are estimated for stands both thinned and unthinned, as a function of...

Five Years of Nitrogen Fertilization in a Sweetgum-Oak Stand
Diameter and height growth were significantly increased in a 20-year-old sweetgum-oak stand by annual surface application of ammonium nitrate and of complete N-P-K fertilizer. Nitrogen fertilization significantly increased the nitrogen content of foliage. With increasing nitrate application, exchangeable potassium in the soil 1 year after treatment decreased.

Influence of family and nitrogen fertilizer on growth and nutrition of western hemlock seedlings.
Effects of genotype and nitrogen fertilizer on growth and shoot nutrients of western hemlock seedlings were determined by using 11 open-pollinated families from coastal Oregon and Washington. The families differed significantly in growth, initially and after one growing season after treatment. All seedlings responded well to fertilizer, and fertilization significantly...

Effects of soil and foliar applications of nitrogen fertilizers on a 20-year-old Douglas-fir stand
We compared growth and cone production of Douglas-fir treated 4 years earlier with ISO pounds N per acre applied as urea prill by hand and as a 32-percent N solution applied by helicopter. Nitrogen fertilization increased growth by 3 88 ft per acre during the 4 years after treatment; this 3S-percent gain was similar for both soil (prill) and foliar (solution)...

Nitrogen Fertilization Increases Cottonwood Growth on Old-Field Soil
Nitrogen (150 lb ./acre as NH4N03 ) applied to a 6-year-old eastern cottonwood plantation in an old field on Commerce silt loam soil increased diameter, basal area, and volume growth by 200 percent over untreated controls. The plantation did not respond to 100 pounds P per acre from concentrated superphosphate.

Changes in canopy processes following whole-forest canopy nitrogen fertilization of a mature spruce-hemlock forest
Most experimental additions of nitrogen to forest ecosystems apply the N to the forest floor, bypassing important processes taking place in the canopy, including canopy retention of N and/or conversion of N from one form to another. To quantify these processes, we carried out a large-scale experiment and determined the fate of nitrogen applied directly to a mature...

Growth response of 35-year-old, site V Douglas-fir to nitrogen fertilizer
During the first 4 years following application, addition of 200 to 600 pounds of nitrogen per acre increased height increment 62 percent and d.b.h. increment 79 to 160 percent. Gross basal area increment was greater with heavier fertilizer applications, but severe snowbreakage wa also increased. Thus, net production tended to be greatest with the addition of 200...
