Forage is the herbaceous plant material eaten by grazing animals. Forage crops may consist of single species or a grass and legume mixture. In terms of their nutritional value, legumes are rich in protein and grasses are rich in carbohydrates. Forages require essential nutrient elements from soil for normal healthy growth. The amounts of these nutrients required vary considerably among forage species. This work covers the nature of forage systems common in the semi-arid and sub-humid regions of the prairies, their fertility requirements, management, relation to soil properties and impact on the emission of greenhouse gases. Studies were conducted at three different sites in Saskatchewan, Canada over two years to determine the effect of liquid fertilizer. A similar study was conducted in Mongolia to determine the effect of granular fertilizer application on dry matter yield, and nitrogen and phosphorus concentration in plant biomass. Mean respiration rates and pattern of carbon dioxide and nitrous oxide evolution were also measured. This book is intended for researchers, students and farmers.
