HUNGER SIGNS IN CROPS. The American Society of Agronomy and the National Fertilizer Association. (1941. 327 pp. Illus. Price $2.50.) Modern science has recently found that many human ailments once believed to be due to bacteria or which were entirely unexplained are really due to hidden hunger failure to supply all of the elements needed by the body. Now scientists have also found that hidden hunger may affect plants as well as human beings that many so-called plant diseases are merely "hunger signs" or symptoms of plant food deficiencies.

This book represents 5 years' work by a group of scientists interested in giving to the agricultural public valuable and up-todate information on plant feeding. It was written by 14 able scientists, all of whom have had many years of experience in the field covered.
