Nutrition of Hybrid Willows for Bio-fuel Production

Seven different clones of willow grown as a potential bio-fuel crop were evaluated in their response to irrigation and N, P, K and S fertilization. After three growing seasons, prior to harvesting the plots for biomass measurements, seven stems per plot were be sampled and analyzed for N, P, Ca, Mg, Al, Fe, Mn, Cu, Zn, B, and Na concentrations. As well residual nutrient concentrations in the soil down to 60 cm (24 in) were assessed.


The study is being carried out in the existing Canadian Forest Service two-year-old hybrid willow plantation, located on 14th Street and Circle Drive in Saskatoon. The plantation is a clonal trial with seven different clones of willow arranged in a randomized complete block design, replicated three times, using a 60 x 60 cm spacing within each triple-row bed and 200 cm spacing between beds, resulting in a density of approximately 15,625 stems/ha.

Interpretive Summary


Willow Biomass Quality for Bioenergy and Bioproduct Applications, 2010 Growing willow as a renewable dedicated bioenergy and bioproduct feedstock is advantageous for a number of reasons, such as its naturally fast growth rate, along with important environmental benefits like providing a much cleaner energy source relative to fossil fuels.
