Hay of excellent quality and high digestibility has been made by a process of artificial drying in which a current of warm air is blown through the grass in a stack. The air is heated by a system of hot-water pipes round which the stack is built.
The resultant product was of much greater feeding value than good meadow hay or seeds hay and was made at a season of the year when hay-making conditions were poor.
The economics of the process have not been worked out.
