The main purposes of irrigation in American and Canadian nurseries are explained. Information is given on the quantity and quality of water used, the types of pumps required for specific operations, and the types of pipes used in the layout of underground supply channels. Three types of irrigation systems are fully discussed along with the main advantages and disadvantages. The systems described are the flood, the overhead lateral line, and the rotary head sprinkler system. The use of mineral spirits as selective weed-killers in conifer nurseries in America is outlined and the position given with regard to products used, their effectiveness, and quantities and times of application. Figures are given on the costs of the materials along with the costs of application.
