• Liquid Fertilizers and Aerated Compost Tea

    Liquid fertilizers create a huge boost, especially when added to already fertile balanced soil. I urge every gardener to try fertigating a few plants and see what it does. A very small quantity of fertilizer applied to leaves has as much (or more) result than many times more of that same fertilizer put into the soil. One foliar feed can produce a dramatic increase in growth and plant health. But if the soil is seriously out of balance/deficient, the result will not be so good.

  • Welcome to the Soil and Health Library Blog

    The Soil and Health Library Association has started this blog to expand upon their vision for this library: to make available works which empower people to grow their own food, be healthy and think for themselves. Self-empowerment is true freedom.

  • Global Soil Biodiversity Atlas

    This fully illustrated publication details what we presently know about life the soil and the complex ecosystem within which life is sustained. Of course, and here is the rub, when the soil is described as being a very complex living ecosystem, the information flies in the face of Industrial Agriculture. Modern farmers, with the help of their agents, have all but declared war on soil life by the use of petrochemical fertilizers and pesticides.

  • The Biochar Revolution: Transforming Agriculture and the Environment

    A free download of Chapter 1 offered by the author/publisher, with a link to purchase the book from the publisher’s website. The Soil and Health Library offers this item because we feel that biochar is extremely useful and should become more widely known and used.

  • Results from the Biodynamic Sowing and Planting Calendar

    Actual trial results from using Thun’s planting calendar.

  • Nathaniel Southgate Shaler Collection

    Nathaniel Southgate Shaler (February 20, 1841 – April 10, 1906) was an American paleontologist and geologist who wrote extensively on the theological and scientific implications of the theory of evolution. Soil and Health Library has a nearly complete collection of Shaler’s publications.

  • Thirty Years Farming on the Clifton Park System

    How to supply Humus, Texture, and Fertility by the Aid of Deep-Rooting Grasses

  • Harnessing The Earthworm

    A practical inquiry into soil-building, soil conditioning, and plant nutrition through the action of earthworms, with instructions for intensive propagation and use of Domesticated Earthworms in biological soil-building.

  • Soil Management

    Published posthumously. King’s study of Chinese, Korean and Japanese agriculture was part of his plan for the work on Soil Management. The chapter on the study of Far Eastern agriculture has been collected by Mrs. King from ten different lectures and papers which he had already prepared.

  • The Soil: Its Nature, Relations, and Fundamental Principles of Management

    Obsolete soil manual.

  • The Soil and the Microbe

    An Introduction to the Study of the Microscopic Population of the Soil and Its Role in Soil Processes and Plant Growth. A thorough overview of the topic.

  • Principles of Soil Microbiology

    Waksman’s massive work of scholarship was refused by many publishers who thought there was no market for such a book, but it became a best-seller and dominated the field for decades.

  • FARMERS OF FORTY CENTURIES: or, permanent agriculture in China, Korea and Japan

    One of the best travel books of all time. King’s remarkable account of his agricultural investigations in China, Korea and Japan in 1909 was an often-quoted source of inspiration for Howard in his 26 years as an agricultural investigator in India.

  • Humus

    The basic text on the topic for decades; a summary of everything known in the mid 1930s.

  • Miscellaneous Papers of John E. Weaver

    The University of Nebraska put a large collection of John Weaver’s publications online for free download. The Soil and Health Library is mirroring this material. Select this item to see the full list of publications with download links to them.

  • Prairie Plants and Their Environment

    This book is the product of a lifetime of ecological research “to clarify some of the many problems presented by this vast natural unit of vegetation, to better understand the importance and significance of grassland and its utilization, and to furnish a permanent record of a rapidly vanishing vegetation.”

  • Soil Fertility

    What every soil analyst needs to know; a university-level textbook.

  • Jones, Dr. Christine, Publications

    Dr. Jones explains how the main creators of humus are specialized fungi that plants feed sugars and other complexed nutrients. These fungi, in turn, help feed plants both nutrients and moisture.

  • Available calcium a factor in salt balance for vegetable crops

    Observations made on vegetable farms in New Jersey located on sandy soils, show that pH is not always a reliable indicator of the available calcium and that many of those sandy soils which have pH values of 6.0 to 6.6, where large applications of soda and potash have been made, may be very deficient in calcium and magnesium.

  • Does a soil acidity test as used in soil testing laboratories determine our calcium need in Ohio soil?

    Many soils in the United States and Canada show a paucity of available calcium even though the pH reading seems satisfactory. A high pH does not necessarily indicate adequate calcium in the soil.
