Book Description
The Interprovincial Forest Fertilization Program comprises 81 standardized experiments established by the provincial forest services of New Brunswick, Quebec, Ontario, Manitoba, and Alberta, and by the Canadian Forestry Service in the provinces of Nova Scotia and Saskatchewan. Seventy-three experiments were remeasured after 10 growing seasons. The field trials were designed to test the effect of nitrogen when applied as urea at the rates of 112 and 224 kg/ha, and the effects of combined nitrogen, phosphorus, and/or potassium additions on the growth of pole-size and semimature conifer stands. In the combination treatments, nitrogen was applied at the high rate, phosphorus as triple super phosphate at the rate of 112 kg/ha, and potassium as potassium chloride, also at the rate of 112 kg/ha. This final report contains the 10-year response data, with sections of the 5-year report included to present a more complete picture.

Book Description
For thousands of years, forest biomass or wood has been among the main energy sources of humans around the world. Since the industrial revolution, fossil fuels have replaced wood and become the dominant source of energy. The use of fossil fuels has the disadvantage of increasing atmospheric concentrations of greenhouse gases (GHGs), especially carbon dioxide (CO2), with the consequent warming of global climate and changes in precipitation. In this context, the substitution of fossil fuels with renewable energy sources like forest biomass is among the ways to mitigate climate change. This book summarizes recent experiences on how to manage forest land to produce woody biomass for energy use and what are the potentials to mitigate climate change by substituting fossil fuels in energy production. In this context, the book addresses how management can affect the supply of energy biomass using short-rotation forestry and the conventional forestry applying long rotations. Furthermore, the book outlines the close interaction between the ecological systems and industrial systems, which controls the carbon cycle between the atmosphere and biosphere. In this context, sustainable forest management is a key to understand and control indirect carbon emissions due to the utilization of forest biomass (e.g. from management, harvesting and logistics, and ecosystem processes), which are often omitted in assessing the carbon neutrality of energy systems based on forest biomass. The focus in this book is on forests and forestry in the boreal and temperate zones, particularly in Northern Europe, where the woody biomass is widely used in the energy industry for producing energy.
