Soil and Health : A Study of Organic Agriculture
Bok av Albert Howard
This is a newly edited revision of Albert Howard's important text on organic farming and gardening, and the central role of humus in maintaining soil health and fertility.
THE SOIL AND HEALTH is a detailed analysis of the vital role of humus and compost in soil health - and the importance of soil health to the health of crops and the humans who eat them. The author is keenly aware of the dead end which awaits humanity if we insist on growing our food using artificial fertilisers and poisons.
Albert Howard (1873-1947) was one of the leaders of the British organics movement in the mid-twentieth century. He was the first westerner to document and publish research on traditional techniques of agriculture, including Indian and Chinese farming and management of the soil.
"Agriculture is the fundamental industry of the world and must be allowed to occupy the primary position in the economies of all countries." - Albert Howard
