Evaluation of base flow separation methods for determining water extraction (Case study: Gorganroud River Basin)

Application of barley straw to remove nitrate from drainage water

ABSTRACT-Nowadays farmers often use N-fertilizers to increase crop yield, but they lost quickly by leaching causes environmental contaminations that reported as most important source of pollutant. Although biofilters are useful for removing nitrate from drainage water, but many researches show that they need an external carbon source to sustain denitrification. Many researchers study on differe...

Evaluation of Nipple Drinkers and the Lott System for Determining Appropriate Water Flow for Broilers

Introduction Water is thought by many to be the most important nutrient for poultry. Charles H. Goan summed up the true concerns of the broiler industry when he stated, “The purpose of any broiler watering system is to provide sufficient water for optimum bird growth and efficiency.” In recent years the industry has abandoned v-troughs, cups, and bell type drinkers in favor of nipple water syst...
