The health of our soils : toward sustainable agriculture in Canada

Interactive effect of tillage and wood ash on heavy metal content of soil, castor shoot and seed

“…The management effect of tillage methods and organic waste application on a near-soil surface is vitally important considering the effect of soil surface on water infiltration, nutrient conservation, trace metals distribution and erosion control. Thus, good soil quality not only produces good crop yield, but also maintains environmental quality and consequently plant, animal and human health (Action and Gregorich, 1995;Franzluebbers, 2002 irrespective of the TM the WA was applied were found to be relatively similar, but higher in value compared to their values obtained from 2tha -1 and 0tha -1 rate of WA. The result obtained could be associated with the type of tillage method, waste applied and water content and infiltration rate of the soil.…”

“…The work is intended to recommend an appropriate rates of wood ash and frequency of application with appropriate tillage method, all with a view to avoid excessive soil accumulation and up take by castor plant, because oil from the seed is very useful to man medically and industrially. 1 of the southeast in the derived savannah agro-ecological zone of Nigeria. The rainfall distribution is bimodal with wet season from April to July and peak in June and September to November.…”

Soil Quality and Productivity Improvement Under Rainfed Conditions – Indian Perspectives

“…A slightly modified definition of soil quality was given by Seybold et al (1999), in which soil quality was defined as 'the capacity of a specific kind of soil to function, within natural or managed ecosystem boundaries, to sustain plant and animal productivity, maintain or enhance water and air quality and support human health and habitation'. Soil quality acts as a major linkage between the strategies of conservation management practices and achievement of the major goals of sustainable agriculture (Acton and Gregorich, 1995). The terms 'soil health' and 'soil quality' are interchangeable.…”

Farms or Freeways? Citizen Engagement and Municipal Governance in Edmonton's Food and Agriculture Strategy Development

“…In contrast, British Columbia, Ontario, and Quebec have provincially legislated delineation of agricultural zones and urban growth boundaries (Hiley et al, 2011). In the prairies provinces, where approximately 80 percent of Canada's farmland is located, there is no legislation to Journal of Agriculture, Food Systems, and Community Development ISSN: 2152-0801 online www.AgDevJournal.com protect this crucial resource (Acton & Gregorich, 1995).
