During the war, when superphosphate was in exceptionally short supply,a wheatbelt farmer experimented with a method of sowing a crop in which he had blocked each alternate drill run and in effect halved the rates of seed and super used on each acre. He expressed himself satisfied with the results and has since continued to plant the major portion of his crop in this manner.
