Show Adding Minerals to Soil Is Found to Improve Food, Research Worker Asserts The average person's life can be lengthened about a dozen years through the scientific addition of minerals to the soil, believes Dr. Charles Northen, who is an Alabama Ala-bama physician and a research worker in the field of mineral colloids. col-loids. "Crops grown in poor soil produce poor 'food products, lacking in minerals min-erals and vitamins," Dr. Northen explained. "Our problem was to discover a means of adding this mineral content to the soil." Dr. Northen set down several con- content of vegetables grown on adjoining ad-joining soil. A dairy used the process on grazing graz-ing land for cows with the result that a glass of milk contained all the minerals needed for an adult during a day. "With soil depleted of natural minerals after years of usage, people peo-ple cannot eat a sufficient quantity of food to supply these necessary items," Dr. Northen declared. "Farm experts have recognized the problem and have urged rotation of crops allowing the land to lie idle every third or fourth year, and similar methods. "But land would have to lie idle for many years to regain the minerals min-erals which have been taken from it. The discovery of mineral colloids col-loids will mean better crops and a healthier and longer-living nation." Dr. Northen said sixteen mineral elements are indispensable for normal nor-mal nutrition. Calcium, phosphorus and iron are the most important. crete results of his experiments, in Florida, orange groves infested with scale became clean and bore fruit with a greatly increased vitamin content after mineral colloids were added. Land used for growing potatoes, celery, cabbage and other vegetables vege-tables was enriched with the minerals. min-erals. Laboratory tests of the new crops showed twice the mineral |
