Ebook with lifetime support · by Ruth Okafor, soil scientist
How soil works, how to test it and how to rebuild tired or difficult ground, with lifetime support
$159
One payment, support and updates includedFertilizer can feed a crop for a season, but it can’t fix a soil that has stopped working: compacted, short of organic matter, with little life in it. Living Soil explains how garden soil works, from sand, silt and clay to the fungi and earthworms that build its structure, and how to rebuild it with methods that fit a home garden and a home budget.
Ruth Okafor starts with what you can observe yourself: the jar test for texture, the spade test for structure and worms, a simple pH kit. Then she explains how to take a sample for a lab and read the report line by line, including lead in city soils. The practical chapters give quantities and timings for hot and cold compost, worm bins, leaf mold, mulch, cover crops and no-dig beds, and a chapter on problem soils deals with heavy clay, sand, alkaline desert ground and caliche, acid soils and compacted new-build yards.
This isn’t a chemistry textbook. Concepts are explained with garden examples and drawings, and the numbers are the ones you need, such as how many inches of compost to spread or when to cut a cover crop. Soil changes over seasons, not weeks: most gardens improve noticeably by the second year, and the book closes with a three-year plan to follow. Along the way, you can send our garden team the results of your lab report from your account and get a written answer within 2 business days. Living Soil Masterclass covers the same ground on video.
