The dangers of these matches at length were recognized in the laws of most nations, including matchmaking Sweden...
...William Frederick Gericke, associate plant physiologist at the University of California, is the biological chef who concocted the food pill. It is about the size of a pigeon's egg, is composed principally of nitrogen, phosphorus, iron salts. The definite recipe is still a secret; each plant requires different proportions of ingredients and many formulas remain still to be worked out. Chef Gericke plans to tell U.

Untreated barley seed in the same soil yielded no crop...
...phosphorus treatment is only one phase of the larger question of plant requirements. Plant Physiologist Gericke suspects that plants, like people, take more food than they need for growth. He has therefore, experimented with balanced rations, which led to a method of growing floral plants in water solutions containing only the essential growth elements. He has also developed a method of growing young tomato plants in cold frames; feeding them special fertilizers; producing a greater crop than the untreated controls...
