Description

Many forestry facilities in Alberta use bark, sawdust and yard waste, commonly referred to as "hogfuel," to generate steam, electricity and heat for plant operations. There are also several facilities that use hogfuel as an energy source to generate electricity. More than 180,000 tonnes of energy system wood ash produced annually at pulp mills, sawmills, oriented strand board and fibre board plants is currently disposed of in industrial or regional landfills.

Liming acid soils

Lime is applied to acid soils to neutralize excess acidity that causes reduced crop yields. The application of lime does not improve saline or solonetzic soil conditions. There are over 1 million... More ≫

Description

Lime is applied to acid soils to neutralize excess acidity that causes reduced crop yields. The application of lime does not improve saline or solonetzic soil conditions. There are over 1 million acres of strongly acid and 4.5 million acres of moderately acid soils farmed in Alberta. While many factors, such as the kind of crop, soil type, and climate, influence responses to lime, it can be generally stated that the application of lime should be considered on all strongly acid soils and on many moderately acid soils to improve and maintain productivity. Where liming is an established practice, it is applied to maintain soils in the most suitable pH range for the crops and soils in the area.

Description

In July 1988, Halfmoon Lake (Strathcona County) was treated with two forms of lime in an attempt to lower algal biomass and phosphorus concentrations. 58 tonne of CaCO3 and 49 Tonne of Ca (OH2) were added to the lake over a five-day period.
