There is no line of farming in the irrigated districts that gives such marvelous profits as that of scientific potato production. With scientific knowledge which can be acquired by experiments in supplying perfectly balanced plant food and maintaining soil fertility, the scientific principles of which are similar to those used by every successful breeder in feeding and fitting prize-winning stock; and with proper proportions of plant foods -- phosphates, nitrogen, and potash -- in the soil as found in many parts of the West; and by the use of clover and alfalfa, there is no reason for those who contemplate engaging in the potato industry to fear the outcome. Too much stress can not be put upon the value and importance of live stock in keeping up favorable soil conditions, as no country now known has been continuously successful in crop production without the use of manures from feeding of forage and grain crops.
