Utility of wood ash, paper sludge and biochar amendments for the mitigation of greenhouse gas emissions from acid boreal soils
Newfoundland and Labrador (NL) soils are characterized with low fertility, shallow, and acidic soils which impede agricultural productivity. Developing agriculture is a goal for the provincial government of NL and to promote soil fertility and crop productivity, manure and inorganic fertilizers appl...
