Effect of nitrogen application on forage yield in alpine rangeland
Large areas of grassland have been deteriorating due to dry climate, simple vegetation structure, poor quality of forage, overgrazing and damage from pests and rodents.Meanwhile, nutrients for plant growth in alpine rangeland depend on biological and chemical mineralization in soil which has been decreasing in fertility because of consumption by plant growth.Research has indicated that N application improved forage yield and crude protein content, which is an important way to solve the problem of protein shortage in alpine pasture which generally has limited legume content.The objective of this study was to determine the appropriate fertilizer application rate for forage yield and protein content.
