U.S. is organized and managed to make full use of all available technology where such use would add more to 
farm receipts than to expenses. » The « B » estimate was formulated on the basis of « a projection to 1975 of 
the yield likely to come about from such application of available techniques as can reasonably be expected on 
the basis of past experience. »

nology under assumed economic conditions. Economic attainable yields are yields that would be expected, by 
1975, from actual application bv farmers of presently known technology. » (Ibid., p. 3)
