The Fertilizer Control was created under authority of the food control act as a war emergency measure in the Department of Agri- culture. Soon after its establishment this office undertook a survey of the fertilizer industry in order to determine the materials used, the products, and the stocks of ingredients and of mixed goods on hand. In view of a serious shortage of several of the materials that enter into the manufacture of fertilizer, it was deemed important to ascertain what the requirements of the industry were, in order to stimulate production of the scarce ingredients, and, if it became necessary, to apportion the available supply of scarce materials on an equitable basis. A series of questionnaires was sent out by the office of Fertilizer Control. The information collected is for the calen- dar years 1917 and 1918. In the case of fertilizer manufacturers a schedule was first obtained for 1917 and the first six months of 1918, and then another schedule was sent out to cover the last six months of 1918. Data on phosphate rock were obtained for 1918, information for 1917 having been collected by the Bureau of Soils. A potash schedule was sent out later in the year, and called for reports for 127491°â19âBull. 798 1. Please note that these images are extracted from scanned page
