This collection includes three valuable books about plant mineral nutrition and deficiencies. The first book, 'The Diagnosis of Mineral Deficiencies in Plants' by T. Wallace, was published by Her Majesty's Stationery Office in 1956, second impression in February. The second one, 'Mineral Nutrition of Plants' by Emil Truog, came from The University of Wisconsin Press in 1951. The third book, 'If They Could Speak' with an unknown author, was published by the Chilean Nitrate Educational Bureau, Inc. in 1941. All books are in acceptable condition. There is moderate soiling on the covers, heavy foxing on 'Mineral Nutrition of Plants', and some soiling along the text - blocks. The bindings are secure, and the pages are clean, slightly yellowed with age. The dust jacket of 'Mineral Deficiencies in Plants' is also in an acceptable state.
These books are great resources for those interested in plant nutrition. To use them, simply open to the relevant sections and read through the information. When handling these vintage books, be gentle to avoid damaging the covers or pages. Since the pages are slightly yellowed with age, try to store them in a cool, dry place away from direct sunlight to prevent further deterioration. Keep them away from moisture to avoid mold growth. If you need to move them, hold the books firmly at the spine to keep the bindings secure.
