As animal density has increased considerably in some regions in Quebec, surplus in animal excretion has been experienced for farms while considering nitrogen and phosphorus requirements estimated for crop production. Water quality problems (by pathogenic bacteria, viruses, high nitrogen and phosphorus contents) can result from high application rates of manure as the climate in Quebec is humid and water infiltration and runoff are frequent in the fall and the spring. Soils enrichment with copper and zinc can also cause problems as in a region of high production density, copper content varying from 1 to 12 mg\/L has been measured in the water (Boyer River watershed) and the standard for drinking water is 1 mg\/L. Even if the pig manure doesn’t provide much organic matter, the soil structure can be improved by an important microbial activity, using the carbon input from manure. Spring manure application and later fall application are the best time in order to optimize nutrients use by the crop and also limit the nutrient losses through runoff and leaching. As the fertilizing value of the manure is almost equivalent to mineral fertilizers value, manure is valuable and should be used optimally in order to limit the environmental impacts and odour nuisance associated with applying.
\nThis article presents well the situation in Quebec associated with excessive manure application that has been done in some regions. Appropriate management of manure in crop production is the way of valorize manure.<\/p>\n","protected":false},"excerpt":{"rendered":"
