I just found out that you can download a classic book on liming and fertilizing, Bread From Stones, This classic, written by Julius Hensel over 100 years ago is a highly recommended read. Julius was a chemist and proved that plants are much healthier when fertilized with rock dust. Every farmer will benefit from reading this book.
I bought a reprint of this last year and really enjoyed it. Julius understood that finely ground limestone worked much better that coarse lime. While there are a few things that have proven to be false much of what he has written will be very valuable to many farmers.
I hope you enjoy it as much as I did.
