The Effects of Manure and Fertilizer on Soil Fertility and Soil Quality focuses primarily on the behaviour of
nitrogen (N) and phosphorus (P) in soil because these two nutrients are the main nutrients that limit crop
yields in Manitoba and they are also the nutrients of particular concern for environmental quality. In addition,
potassium (K), sulphur (S), macronutrients and other trace elements, salts and sodium, soil pH and organic
matter and microbial activity are covered.
