OCTOBER 1953

GREENS FOR DINNER--"Many scientists all over the world are interested in the food possibilities of the water plants called algae. On the basis of laboratory experiments it is estimated that each acre given to cultivation of Chlorella could produce an annual yield of 20 tons of protein and three tons of fat per acre--astronomical figures compared with present rates of production in conventional agriculture. Whether algae can be an important contribution to the world food supply will depend on the cost and the yield of large-scale culture. The production of each ton of algal protein requires about 1.1 tons of potassium nitrate and .75 ton of ammonium sulfate."
