This 2-volume set is a must - have for agriculture enthusiasts. Volume 1, 'Plant Analysis and Fertilizer Problems Vol. IV', is authored by C. Bould, P. Prevot, and J.R. Magness, published by the American Society for Horticultural Science in 1964. Volume 2, 'Plant Regulators in Agriculture', is written by H.B. Tukey and published by John Wiley & Sons, Inc. in 1954. The books are in acceptable condition. There's minor to moderate soiling on the covers, some foxing along the text block, and the front free endpaper of 'Plant Regulators in Agriculture' has yellowing due to adhesive. However, the pages are clean and bright, and the bindings are stiff yet secure. The dust jacket of 'Plant Regulators in Agriculture' is also in acceptable condition.













These books are great resources for anyone interested in agriculture. To use them, simply start reading from the beginning to gain a comprehensive understanding of plant analysis, fertilizer problems, and plant regulators. When handling the books, be gentle to avoid further soiling or damage to the covers. Since they are old books, keep them away from high humidity to prevent more foxing and yellowing. Store them in a dry, cool place on a flat surface to maintain the stiffness of the bindings. Enjoy learning from these valuable agricultural references!
